False wall and audio sound

[Resident Loser]

Any acoustic suspension, or ported speaker with the port on the front can be used in a baffle wall. Ribbon, Ribbon panel, Electrostatics and other exotic speakers, probably not.

And yet earlier:

If you are speaking of a baffle wall, that will increase bass tremedously, and get rid of some modes and nodes in the room. THX actually recommends this for THX certified rooms. I would not recommend boxing the speakers, that would create resonances that are undesireable. If you build a wall with speaker cutouts for the left, center, and right speakers with acoustical foam surrounding the speakers, you will get pretty good sound.

Well, at least we now have a bit of specificity...your earlier response was shall we say a. er...vague, to the point of being downright misleading.

Also, That word "any"..."any"one reading your initial response replete with "THX" and "baffle walls"(love that jargon!) might actually come away from the encounter thinking, hey this guy says I can do it and it's no big deal. And what about "any" speaker enclosures whose front baffle design and cabinetry are used to minimize edge diffraction? Are we now going to defeat the designers purpose and simply surround the niche, alcove, hole, with wall treatment?...can it be done? Sure, maybe but, do try to keep your suggestions within the context of the posters plight...he's looking for a solution that will appease his sensibilites. Also, please...a wall is a wall is a wall is a wall...avoid the jargonistic "baffle" cr@p unless your intent is to, well... baffle!

If this was a serious question, I would answer it. As it stands now, its not worth answering. Perhaps you could re-write a more intelligent question I can respond to.

Well, if you could get out of your soundbite mentality and take in the paragraph as a whole, perhaps you could come up with some sort, any sort of response...after all I'm simply "parroting" your earlier suggestions...Oh, how quickly they forget! And it does seem as though something got through, particularly in light of of your new-found specificity...as in your first quote above.

I never said look in the THX placement guidlines did I? I am referring to THX certified ROOMS, not speaker positioning. I think you are stuck in the old school, baffles have been used on a great deal of custom theater designs. They are used in studios, THX and HPS theaters, and in hometheater installs if the customer want to place the speakers behind the screen. The speakers do not have to be THX certified to be placed behind a screen. You can choose to use a baffle, or a shadow box in mounting speakers behind a screen.

Infinite baffles? As old as hi-fi and maybe older, no argument...HOWEVER the drivers(mostly raw)and their specs( natural roll-off, compliance, etc.) are taken into account...Or do you refer to "baffles" used to break up room nodes...or is it apples and oranges?

Then we have "I am referring to THX certified ROOMS" and in the same breath "The speakers do not have to be THX certified". Are you trying to confuse or are you simply confused? In order to get the little "Certified HT" plaque from THX, dontcha' hafta' use certified gear? Or is it simply dependent on how much you pay your contractor?

Yeah, you can certainly buy acoustically "transparent" screens AND you can get THX cert. loudspeakers, again with compensatory circuitry, specifically for this purpose...Once again, you can put your enclosures or drivers in any configuration you chose, but they need to be either designed for the purpose or mechanically/electronically manipulated to compensate for their environment. At the risk of repeating myself, our poster HAS some gear and has a question...we aren't back at the drawing board to lay out a budget, etc.

I have used klipsch speakers, M&K, JBL, older Snell, Tannoys, and PMC speakers behind a screen and mounted to a baffle wall.

Mounted to or flush with? Were they intended for the purpose? Were our posters PSBs?

Just because a speaker is mounted in a baffle doesn't mean it cannot be aimed at the primary listening position. Its called pre-planning, and theater design. Have you heard of such concepts?

Again, the poster is looking for his speakers and his screen to lie in the same plane...yes, things can be done BUT what you suggest is irrelevant to the subject at hand, i.e. the poster's inquiry.

Logic would dictate that not all speaker designs can be mounted in a baffle. I wouldn't and don't recommend exotic speakers in hometheater setups I install.

Not being certain where on a scale of one to ten on the "exotique" meter the PSBs are, I kinda' think the "baffle concept" would not be an option.

Ummm... you don't use laser alignment tools for calculating beam patterns. You use it to accurately alignment a speakers center axis to a particular point in space(preferably so both speakers center axis intersect just behind the head). This is pretty difficult to do by eye accurately.

So I'd guess were no longer dealing in the realm of THX certification(which, as I recall, requires a minimal dB difference between ANY two spots in the soundfield)and are simply speaking of approximating the "sweet spot"...this is only difficult to do if you've never had experience with design or construction...I rely on my ability to do so, must be the artist in me.

As for your links...well, somehow I don't think we are dealing with the expenditure level required as indicated by the HTs they represent...I have the feeling it's probably a tad lower in our poster's case...getting into the fruit salad as usual?

The behind-the-screen baffle wall...geez I'm gettin tired of sayin' it but...say it with me now...designed for, designed for, designed for...The poster's PSBs, not so much...

Re: the remainder of your attempts at insult and other sundry prattle...the poster's needs are relatively simple, the solution is not quite so, there are no generalties that apply and I have merely attempted to point that significant fact out...sorry if it bursts your over-inflated ballon.

When the gentlemen desides he wants to do this, I am sure he will find somebody competent to help him out.

Which begs the question, why is he HERE? and a second one which I will spare you, given your already somewhat bruised ego.

And of course we never really did touch on this issue:

Personally I know of no consumer speaker manufacturer who states plainly how far from the walls to place their speakers, except Bose. I know of no speaker company that designs consumer speakers with certain distances built into their specs.
