I am a newbie and trying to learn from the pros here... Generally speaking, does it mean the "more way" a speaker has, the better it is than a "fewer way" speaker? Simply put, does it mean that a 4 way speaker can reproduce better sound quality than a 3 or 2 way speaker?? Nowadays, there are speakers on the market that have 2.5 way? What does that mean?? Many thanks for all your comments.

None is better than the other. All speaker designs have trade-offs, no matter how many drivers they use.

Speakers should not be looked at based on their driver amount. There are some single driver coaxial speakers that outperform two way speakers, some two way speakers that outperform three way speakers and so forth and so on.

You ever heard the term never judge a book by its cover? That goes the same for speakers - never judge a speaker by how many drivers it has. Good sound can be had by all designs in the hands of a talented speaker designer.

Quality over qty.
The number of drivers does not mean as much as the quality of the drivers, design and crossovers,

Great comments. I notice that the more high-end speakers tend to have more drivers, thus, implying the more drivers a speaker has the higher quality of sound it can reproduce. This is why I am confused. So why does high-end speakers have, in general, more drivers, if the quality of the sound is the same regardless of the number of drivers? Thanks

Here is a state of the art two way available for $27,000. There are some very nice speakers using a single full range driver. Much depends on what is most important to you in your choice of speakers and the equipment you will be using with them.

Designs using more drivers provides greater power handling and wider bandwidth. There are some systems like the Scaena that employ dozens of drivers in a three-way design. This they do not only for power handling, but also to act as a vertical line source. As for me, I prefer the inherent coherency and transparency of using a single very large driver whose mass is less than the air around it They will not, however, deliver 100 db output nor vast quantities of first octave bass unless you employ them in large arrays.

A "two-and-a-half" way speaker implies using two similar drivers (usually woofers) that have overlapping frequency ranges. One is optimized for the low end at cuts off more quickly. The other is allowed to respond into the midrange to blend more evenly with the tweeter. An example is the Paradigm Studio 80 using two 8" drivers and a 1" tweeter.

Hi-End is only for the best quality of sound.
When some one have a lot of money he has a big listening room so he buy a 3 or more way speakers to fill thos big room with music. Mostly to have a better performance on bas.
For e.g. you can buy MBL 101 (great speakers), or if you have really big room you can buy 101 Extreme with two huge subs.

Here is a one way speaker - one of the best speakers I have heard. It almost does it all - it's as good as midrange gets, it has a nicely open controlled treble band and more bass than most people will need - and to top it off it is highly sensitive and efficient making any amplifier choice on the market acceptable. It's not quite there on the driving bass that I think it needs but overall here's a one way speaker for a reasonable amount of money (albeit reasonable is still way more than I have - LOL) but there's a lot of bigger far more expensive speakers on the market that are not as capable in my opinion.

This illustrates that one driver is enough - at least if well executed

http://www.teresonic.com/product_speakers.htm#1

There are also some nice speakers using a LOT of drivers from Scaena and Perfect8 technologies which shows that you can make a nice sounding product with a lots of drivers. It's in the execution of the design. The "multi-way" designs are tougher to do properly in my opinion and they tend to get very pricey - and even then the expense often outstrips the results.

Hello Ken,
That's a good question. I think that you can ask the same about lots of other things. Such as: do the size of the pistons (displacement) equate to the most car engine power?

The answer to this is: "it depends". My 1998 Volvo S90 has less displacement then my 95 Grand Caravan. But, my S90 runs circles around the Caravan. It has: significantly higher compression, tighter engine design, etc, etc. So, it really has much more power.

With speakers its the same. Some speakers have lots of drivers BUT sound really poor. What matter is the engineering that goes into the speaker. Not just the number of drivers.

Best Regards,
Stan

It is difficult to design a single speaker that covers the complete range of the human hearing. Possible but expensive. So a combination of units are normaly used to reproduce the desired sound range and a crossover is needed to separate the octaves that are to be send to this or that unit.

But crossover adds distortion (back to this nasty bit later) and being that we hear much better in the 1000 to 5000 Hz (vibration per seconds) range just where a 2 way speaker system would have it, some designers went to a three way (or more) system. Not only will you have a tweeter to reproduce the higher sounds better, you will have a woofer for the lows and maybe a mid (we older folks may remember the term "squawker") for...well, the mids.

So where does a "sub woofer" comes from? Well as the name state, it lives below the woofer. You can not have a subwoofer if you are without a woofer to begin with.

Now, not only do we have a number of distortions created by the crossover, we have more problems matching the various speakers sound qualities, keeping to sound waves emited by each units in sink with each others and dealing with more vibrations coming from the box that contain all of the above.

This is where the "art" of building a truly great speaker system begins. Do I use a single unit and avoid the crossover's nasty distortions? Keep to a two way and have a simplier crossover? Go for a three way and avoid the area where our ear hears the best? Have a big box that may extend the low notes? Keep it small to minimize vibrations generated by the box? What is best?

Have fun finding the best speaker for your listening needs.

Are there actually single speakers which will reproduce full-range (20Hz-20KHz) +/-3db? I've seen many single driver speakers declare they're full-range, only to read the specs and see their ranges listed as, for example 40Hz-17,500Hz +/- 3db. Being over 50, this probably isn't a big issue for me, but to someone (younger) who can hear full-range, they may feel a bit cheated.

The physics involved say a 1" driver will never be able to reproduce 20Hz, or a 12" driver reproduce 20KHz, so there will always be a compromise, either in freq. response, dispersion or level. This is where multiple drivers and xovers come into play. A good engineer will use appropriate numbers of drivers, design box/panel and xover to minimize the compromises. Some may have better mid-range, but boomy bass, excellent frequency response, but poor power handling. This is where the big money comes into play designing custom drivers and cabinets using exotic materials and designing intricate xovers. This is also where diminishing returns on investment also come into play.

I have a pair of Legacy Focus 7-driver 4-way speakers ($6800). I also have a pair of Klipsch Kg4 3-driver+passive 2-way speakers ($600). The Legacys are definitely a better speaker, but are they $6300 better? Maybe? (there's no substitute for 6 12" woofers for HT). Both are excellent speakers. Both will always have a place in my media room.

When you don't limit the discussion to dynamic drivers, the answer is yes if you adjust your cutoff to 25 hz. In room bass response (yes, there is some room gain) of my Sound Lab U-1s is flat to 25 hz where it disappears below that. It is a full range electrostat with about 15 square feet of 2.5 micron diaphragm per speaker. While they are not ideal for HT playback of planets exploding, they do a fine job at reproducing music at levels up to 90 db. High SPLs can be achieved with this type of speaker, but you would need to put together a suitably large array like Ray Kimber has demonstrated at RMAF.

From what I understand after reading your great comments, the number of drivers have nothing to do with a single/2 way/3 way, etc, system, meaning a speaker can have, for example, a 2 way system and at the same time has 7 drivers. Is my understanding correct?

Which brands are better in terms of good engineering going into the research & development of the final products? How would one rate these brands. I understand that this is so subjective and everyone has a preferred brand. Taking everything equal, which brands would rate higher than others?? I often hear that Japanese speakers would always rate inferior to American, Canadian and European. Is that true?? On the other hand, Japanese hi-fi equipment, like receivers, TV's, blue-ray players are always rated very highly. Is that so? Thanks.

Yes. Roger Russell's equalized IDS-25 (http://www.ids25.com/brochure.htm) line array employs twenty five drivers per speaker in a one-way design. The exceptional Scaena 1.4 (http://www.scaena.com/main.htm) is a three way design using twelve ribbon tweeters, fifteen midrange drivers and two subs per channel. I heard a pair driven by VTL Siegfrieds. They offer jaw dropping performance.


Which brands are better in terms of good engineering going into the research & development of the final products? How would one rate these brands.
There are quite a few very good companies making wonderful speakers. It all boils down to your set of priorities and budget!


I often hear that Japanese speakers would always rate inferior to American, Canadian and European. Is that true??
As with American brands, there are the mass market flavors and the niche market players. While I've never been fond of the mid-fi Japanese product, they do make some nice higher end stuff be it dynamic, horn or electrostat.


On the other hand, Japanese hi-fi equipment, like receivers, TV's, blue-ray players are always rated very highly. Is that so? Thanks.
As a rule, yes. Don't get too bogged down with such hard rules.

I would not get too caught up on frequency response - whether a speaker hits 20hz or 30hz - if the speaker doing 30hz sounds better then while the other speaker may have spec bragging rights it doesn't mean much if the bass is one note sounding or can't create the visceral pressure of the instrument in the room.

You can follow our show report and see many different designs and how they did versus other designs. At the end of each reviewer's show report most of us put our favorite rooms - and there is a lot of shared results - meaning most of us heard most rooms the same way. Sometimes not remotely so. http://www.dagogo.com/View-Event.asp?hEvent=25

I don't think you can necessarily compare one design off the other. At the end of my show report which is quite a ways off I list my favorite 5 budget rooms and 5 above $10k rooms based on the price of the loudspeakers.

My five budget rooms have a couple of 2 ways (stanmount and floorstander), a couple of 3 ways, and an electrostatic panel.

Thank you all for your very insightful and excellent input. The other question I have is regarding the quality of the speakers. Why is it some of the very high-end manufacturers (like Teresonic) have never won any single award whereas those in the mid to expensive manufacturers (like Paradigm) have won many awards from industry experts. Please correct me if I am wrong !! I would think that the very high-end manufacturers would have spent a fortune to get the best acoustical engineers and best cabinet designers, etc to come up with their final products which, in theory, should be the best and yet they gather less awards than the less expensive manufacturers. Why is it? Many thanks.

RGA
02-11-2010, 08:11 AM
Awards from whom? Anyone can give out awards for products they may deem to be better suited for mass appeal or by price or functionality. A British magazine awarded the Roksan Kandy their supertest 5/5 shootout winner for amplifiers but the Sugden A21a an amp they gave 4/5 they noted as sounding by far the best of the group - but the Sugden had less features and less power and looked dumpy. But if it was about the sound then it was clearly viewed as the best sounding unit. Back then Sugden also didn't pay for print advertising which may or may not effect some magazine ratings.

I'm not a big fan of awards because unless the specific reviewer heard everything in the speaker class how can he award one as the best - best out of what he has heard which in some cases may not be very much.

Sometimes too - several writers for a magazine actually pay for a certain speaker - they liked it enough to buy it. The magazine may not give it a top rating but always remember that there are other factors, appearance, idiosyncratic requirements, size, looks, features (is there a home theater package available) what have you.

Perhaps, you can enlighten us as to who those people are. For me, I have no clues whether they come from credible organizations or from some " amateurist bozzos"!!! I guess a reputable company like Paradigm would not mislead consumers as to the credibility of these awards - they must mean something worthy. Do they????

Who cares about awards the country of origin or how many speakers are in the box? None of those things mean diddly. The only thing that matters with any speaker is, do you like it. Nothing else matters in the slightest. Well price and size may have some significance but If you want the speakers bad enough even they won't matter.

Paradigm makes a lot of products over many years. It may be that in their particular price class they view a given Paradigm package of home theater speakers as being the best - and who knows maybe you and I might agree with them - but the more important question is what else did they audition?

The thing is when you compare a tiny company like Teresonic or Sonist or Gallo etc these guys are not very well known compared to gigantic companies like B&W and Paradigm. Many magazines with very good intentions are out to compare BIG speaker makers that tend to be in every city all around North America - so when you walk around you are assured of seeing Paradigm B&W and Klipsch someplace. So it makes some sense to compare Paradigm and B&W to a Klispch or a Polk or whatever. But have any of those guys ever even heard of Teresonic or a Sonist or a Studio Electric or King Sound let alone auditioned one? I'm betting not very likely.

I started way way back assuming the same thing - you would very logically assume that if a B&W (enter model here) is going to be very good because of the sheer number of reviews. And you know many of their models are pretty good. I auditioned a Sugden A21a in the early 1990's - at that time (before the internet) I was thinking wow this is great - who the hell is Sugden. I then auditioned an Arcam Delta 290 - roundly reviewed as the best integrated amplifier in its price class. And it sounded good but the Sugden was a lot better. But being a newbie I said well you know it got an editor's choice award in a Brit magazine, Stereophile raved - it was the least expensive class B amp they had. Award winner in several other magazines. Sugden who? So I decided that perhaps it was the room acoustics and that I should trust the magazines. And the Arcam was good - it wasn't like it was junk or anything but it really is outclassed by the Sugden.

Sugden's view was 'If we build it they will come" and didn't bother actively seeking out reviews - they could care less - they were entirely about word of mouth sales. As my dad used to say - the more they advertise a movie the more it probably sucks. And he's not too far off. Plus you have to factor in price. The S2 for example is not too expensive but I found the upper mid lower treble and lack of dynamics at reasonable drive levels to be completely unacceptable - Stereophile liked the speaker a lot - but noted the very same problem that I noted but for whatever reason they were less bothered by something that to me is not something I can stomach whatsoever - I believe they raved highly - but did any of their reviewers actually buy the loudspeaker to use as their main speakers? That is more important to me than any award.

To answer your question, I have to go back some 50 years and that is a decade before anyone ever heard of Paradign. Back them our national government built a research center in Ottawa and employed the most knowledge individual to run it, if my memory serve me right, a Dr. O'tool. His interest was sound reproduction, how our ear hears stuff, how this sound is affected by the room it is produced in and the likes.

He did something that was unheard at the time, he open this lab to anyone who wanted to test speakers, do research on our hearing, on how our brain takes these sound waves and makes sense of them. Paul Barton of PSB was one of the early visitors so was the fellows at Dayton-Wrights who build some great electrostats back in the late 60's. Soon a numbers of great Canadian speaker companies made surface, like Energy, Sound Dynamic, Paisley and many more.

Paradign came out of this same lab. But they went one step further, they built their own lab and soon their speakers started to be noticed by the various trade publications...and awards followed. Their Monitor 5 Serie 1 was way ahead of its time and was available at a great price. Yes, these awards do mean somethings.

Because todays computers can do most of everything this great lab was doing 50 years ago and do it in basements and garages, todays speaker designers have the know how at their finger tips with at a very little cost to built some great sounding speakers. These last 10 years, I listen to some amazing speakers built by some "golden ear" with the help of his friend, a cabinet maker.

Doc Sage

P.S. I am listening to Miles Davis on my Josephaudio speakers powered by a Sugden amp. Since I purchase these two pieces of equipments, I have no more urges to upgrade.

Unfortunately things aren't as simple as we'd like them to be. A 3 way may not be better than a 2 way. To a point the 2 way has a better chance since it's simpler to design and will have better quality drivers. If the 3 way has the same quality drivers and more attention is paid to the design then it has the potential to be better, but it's not a given.

What is a 2.5 way? It's essentially a 2 way where one of the two midbass drivers has the mids filtered out. The other midbass driver will cover midrange and the bass. With a 2 way using two midbass drivers, bafflestep compensation is required, but the 2.5 way is an alternative way to do it. If you see a floorstander with a TMM arrangement then it's probably 2.5 way, and if it's an MTM then it's probably a 2 way, but not always. It's not a major difference, and not the basis for choosing one over the other.

If crossovers were perfect, and driver quality a given, then more drivers would be better. But there are many different simultaneous trade-offs. In a nutshell, you can't say 3 ways are better. As with many things "it depends ..."

This also a reply to you on the other thread. A crossover is not necessarily a problem if it's done properly and the two drivers being crossed over have very similar characteristics (something that is not looked into very often and which may be blamed on the crossover)

Every driver has a sonic signature - A ribbon produces a given frequency differently than a metal dome or paper or silk or diamond etc. And that also applies to the woofers. There is a "handoff" or point where the woofer and tweeter are reproducing the same frequencies. You could have terrific crossovers and measurements but it doesn't mean you won't hear that step as annoying. The appeal of two way speakers is that there is only one crossover - in a 3 way you have two crossovers and it's very difficult to get it all to mesh.

So you might say - buy a single driver and avoid the whole porblem by not having a crossover. That's fine it solves one problem but adds other problems. The one driver now has to be able to create the nuance and subtle shadings of microdynamics and also has to produce bass at level with impact and finer subtleties of the treble band from a single driver. Generally the good ones like Teresonic have a rather large cabinet that can extend the bass frequencies in some sort of Transmission Line or Quasi Transmission Line. The Teresonic Ingenium does a terrific job and extends into the lower regions very well. Treble is extended and the midrange is fantastic. The compromise is the bass dynamics of rock is thinned out because at high volumes the speaker is still trying to do it all. So there is a slight slowness to the bottom end that basically compresses. This is a minor quibble if you listen at moderate volumes and music suited for it. Heavy rock you would want something else.

Crossovers and boxes are not the problems - the fact is most (the VAST MAJORITY) speakers are multi-way and use crossovers. And the thing is most people hear bad examples of these and conclude that all boxed speakers and all speakers using crossovers are bad. It's not unlike people who rail against American movies. All American movies open in theaters in North America - and msot of them are terrible. And it seems like the import films from Russia, France, Germany etc are so much better - yes but the films that get imported here are the "best" of the films from those countries - we don't get the piles and piles of abysmal films they put out - we get their Cannes award winners and academy award nominees in the foreign film department.

There may 5% of boxed speakers with crossovers that sound very good. It's very possible that people have not heard a single boxed speaker that falls in the 5% "great" camp.

Well said... I've never been a fan of using dramatically different materials for tweeters and woofers... All the examples I've heard doing that, call too much attention to themselves... I just don't hear a cohesive sound when an aluminum tweeter is mated to a Kevlar midrange and a paper bass... I find that speakers that use consistent material from bass to tweeter are able to sound more cohesive...

RGA said it well.

Audio is all about choosing the best compromise. A lot of guys prefer single full range drivers because of the idea of avoiding a crossover completely, and because they want to get closer to the ideal of a point source loudspeaker. Single driver speakers like all speakers do some things well and others not so well. They are considered good at imaging and a lot of them use an efficient driver which needs a large horn loaded box to keep the efficiency down low. A lot of them use a whizzer cone to get the treble.

Unfortunately their weak points put them into a niche. IMO they create bigger problems than they solve. A multi driver system allows different drivers to be designed for ideal dispersion, low distortion, low coloration within a limited bandwidth. A full range driver is trying to be all things at once.

I find that speakers that use consistent material from bass to tweeter are able to sound more cohesive...

Exactly - you see a lot of makers advertise their tweeter or woofer and I always go back to the B&W 705 versus the AN AX Two example. B&W heavily and I mean heavily advertises their tube tapered metal tweeters and ultra stiff kevlar woofers which in themselves are probably quite nifty products. Cabinets look nice and use good connectors. $2300 and it looks the part. The AX Two is $700 and uses two rather dumpy looking Vifa Drivers (silk dome tweeter paper woofer) in decent cabinet with good connectors. The B&W has more extension but the AX Two sounds more cohesive. So do the Dynaudio Audience for about half the price of the 705. Ragarldess of cost I have yet to meet anyone who has heard the two and found the 705 better.

Quad wrote a whole thing about this very issue with choosing matched drivers. The two Vifa's are made for eachother. Kevlar is not made for a metal tweeter. Interestingly the B&W 302 I once had was quite a nice match - no kevlar - soft dome tweeter - sounded better than the 602 from a balance perspective. The only thing I can think of is that a brighter speaker will draw the ear better in a short audition at the stereo shop. It sounds like there is more treble and you can identify bass characteristics more on a short audition - whereas a balanced speaker tends to sound less exciting or possibly polite in comparison, at first anyway???

I think the problem with the big multi-ways is that they get too far from the point source ideal and you get a situation where the ear is drawn to the drivers making it tougher to suspend one's disbelief. Some big multi driver speakers are a lot better at it than others but I am looking at the rooms I felt were the five best of CES - my criteria is the ability to reproduce music so I forget about the gear - which after all is merely a tool to get the results. I personally am uninterested in the technology other than as conversation points to figure out a correlation.

My top 5 rooms at CES based on speakers above $10k have
2 two way standmount speakers of relatively modest size
2 single driver speakers of rather large size
1 multiway horn with mid treble and 3 woofers weighing over 300lbs each (it's also $30,000 more than the next closest speaker on my list - and I'm not convinced it was the best). As good but not better - depends on priorities.

Good points, that’s will explain every thing and I agree with you. Back in early 70s we use to have and I think many people had: big cabinet with TV in one side, tuner and turntable in the other side (left), 2-way speakers located below them (by the way this is definitely best speaker setup than bookshelf or towers). The sound was very good no coloration or anything, directly and simple not heavy like 3 way, midrange strong and apparent unlike modern speakers, and the bass very rich filling the room. I don’t remember I sew crossover so I assume its coaxial design.

Other example is Electro Voice speakers, which installed in our theater in 70s, very natural sound particularly high frequency very soft no harshness at all, there are unique colors (not coloration) in midrange that SO special, it’s easy to identify different sounds, and its none fatiguing sound too. I would describe the sound: natural MORE than nature! The sound was magical until now and I couldn’t find any speaker at present have that quality (best performance) Including reference B&W, Wilson, MG20.

These are two things from the past im dying to have them again, I don’t want go to commercial shop and meet new generating because their interests is to sell. Sometimes I don’t prefer demo unless im sure I don’t like wasting people time.

Closed-cell foam is more expensive, but that investment pays off in a higher R-value per inch. In addition, because of it's 'sticky' qualities and rigidity once cured, it can also provide increased structural integrity to walls and ceilings.
