The MAGNEPAN TYMPANI Speaker

[luckydoggoldminer]

My first real good speaker was a Magnepan mg 1 in 1978. I brought it with me when i first went to college in nothern california. my room mates were stunned at the realism offered by these unique speakers. So many parties and qustions later the local retailer started selling them a couple years after. I then found a pair of magnepan tympani 1Bs. These speakers were three paneled per side to produce a wide soundstage that no other speaker can copy. Each side is a min of four feet wide and can be un hinged at the tweeter panel to be even wider. The speaker i settled on is the tympani 4 and the single panel mg 3.3. These MAGNEPAN TYMPANI 4s will produce such detail that you will hear the guitar players breath and fingers pluck the strings. The main great thing for me is the mid bass slam. They dont produce much below forty hertz but can be the best speaker used in a huge front projector system if you have the room. You will need the cleanest power you can get and also a good clean pre amp. A nice amp to get is the yamaha b2x or anything with a good and clean power supply. They range from a thousand and up. The earlier TYMPANI 1A,1B,1C,AND 1D were two ways but still great sounding. The newer TYMPANI 4 AND 4As had true ribbon tweeters you have to be real carefull not to damage if you play realistic levels in your theater. The older Tympanis work better for theatre because of this but contact MAGNEPAN on their ability to repair these older speakers.

You should read the signatures of other posters. Several regular posters use Magnepan's. One of the forums here is devoted to planar speakers; Maggy's, esl's, ribbons etc. I used Maggy's in the past. According to an old Stereophile poll more of their readers own Magneplanar's than any other speaker.

I was just offering my opin on the speakers! ok dude?

JoeE was not challenging you, Mr luckydoggoldminer...................

Many of us do have Magnepan speakers....................

I have used Tympani 3A's T/M/W since 1974, with a Velodyne SS coming in below 50 Hz. Only a servo-sub is articulate enough to blend with Maggies. Magnepan will rebuild their older speakers.

But I chose the Tympani 3A *only* because I heard them driven with a Futterman OTL amp. I even did not like the Tympani's when they were driven with ARC tubies. Go figure......

Magnepans are simply not all that attractive when driven with SS amps. The Bongiorno-designed Ampzilla I have that works so beautifully on the bass panels was merely OK on the T/M panels.

OTL amps like the Futterman, the original OTL amp, usually work well with speakers rated at 8 ohm or above because these amps "tend" to operate as constant-current sources. But one can try an OTL with 4 ohm speakers by using Paul Speltz's autoformers....

I also use a Jolida 302B, with Winged-C tubes in it, to drive MMG's in our bedroom with very pleasing results. A Musical Fidelity A2 constant-voltage source amp was only decent with the MMG's.

I had MG-IIs in '76 before moving to electrostats. Note that there is a planar speaker sub-forum where you can find others who enjoy them. There's also a Magnepan Users Group forum (MUG) found here.

I once used a Pair of Tympani 1BS for a center SPEAKER ALONG WITH FOURS FOR THE FRONTS AND MG3As FOR THE REARS. THE PRESENTATION WITH A FRONT PROJECTION SET UP WAS AMAZING. I USED A YAMAHA B2 FOR THE CENTER AND A YAMAHA B2X FOR THE FRONTS AND A YAMAHA B2 FOR THE MG3As. I LATER REPLACED THE THEATER SPEAKERS WITH VERTEC SPEAKERS THAT WERE UNIQUE IN THAT THEY WERE MADE OF GUNITE AND USED DANISH AND GERMAN DRIVERS. I STILL USE THE TYMPANIS FOR SERIOUS LISTENING.



I began to edit your post so it is not in all caps. Please finish what was started.

A friend of mine has a multi-channel system built around current Maggies - 20.1s and dual CC3s up front with 3.6s in rear. Drives them with Conrad-Johnson and Edge amplification with a Sony projector and 100" screen. Very expansive sound and wonderful picture.

I combine the best part of two great speakers; Martin Logan
Summits (woofers not used) with Magneplanar Tympani
IV bass panels (modified). The electrostatic portion of the
Summits has great low level detail, imaging (no xover) and
a wonderful sound-stage. The Magneplanar Tympani
bass panels being a dipole, very light in mass, large surface
area, provides powerful, well controlled, huge depth, and
bass with awesome impact. The Maggie bass panel are
bolted together and to the floor, which improves transient
response and lowers distortion. I also extend the bass
response with the Eminent Technology TRW-17 rotary subwoofer down to 1 hz!!!!! These speakers are in placed
well away from all walls and the room is completely
treated with 36 ASC tube traps.

Impressive concept. What amps power the respective speakers and what sort of crossovers do you use

I use an Arcam AVR600 Receiver to drive the Martin Logan Summits
(woofers not used), Martin Logan Logos center channel, 4 Gallo
Nucleus Micros for rear channels, and 2 Gallo Nucleus Micros and 2
Spica TC-50s for side channels. The Arcam has great current capabilities and truly state of the art in sound. It has superb detail,
imaging, depth and fantastic spacial reproduction. To drive the Magneplanar Tympani bass panels I use a Audio Research D400MKII power amplifier which is controlled by a Mark Levinson 380S preamp.
The Magneplanar Tympanis impedance is 4 ohms and the Audio
Research power amplifier provides 400 watts at that impedance.
This amp has superb bass transient capabilities and also great
depth. The Summits xover is 270 hz and the Magneplanar Tympanis
low pass xover is 250 hz at 18 db per octave (modified with quality
parts) and the two speakers have a very good transition. The two
speakers being dipole are a wonderful match and integration is
fantastic. The Eminent Technology Rotary woofer gets most of the
power from the ac current rotating the fan blades, and the fan
blades are pitched by a rotor woofer controller, specifically designed
by Marchand Electronics. A low pass xover in this controller is set
to 25 hz, at 18 db per octave and the rotary subwoofer provides bass
down to 1 hz!!!!!!! Once again the integration between all these
speakers is awesome and is a speaker system that is simply realistic,
powerful and one that would be hard to beat.

That reminds me of Harry Pearson's mating of T-1Ds with Infinity QRS ribbons in the late 70s. Tympanis have always done very well at the bottom. I confess that I've never been a fan of MLs because of their lack of coherency as compared with full range designs. Mating them with dipolar Maggies is a nice answer.
