However, this brings its own set of complications. Multi-driver center-channel speakers tend to have a
"picket fence" dispersion pattern, which means that as you move from left to right (or vice versa), you run
into sonic hotspots and nulls caused by the different drivers' acoustic cancellations. A single diaphragm,
such as that used by the MMG W, avoids the hotspot/null problem, but flat panels work best on-axis -move to one side or the other and the sound drops off. The answer is to bow the panel so its curve
broadcasts sound across a wide pattern. It sounds easy, but it's devilish hard to pull off. Somehow
Magnepan has managed this nifty little trick.
The MMG C may not be the best match for every loudspeaker, but it's sheer perfection when mated to a
pair (or two) of MMG Ws.
To be prepared against surprise is to be trained...
The sound of four MMG Ws and a MMG C, mated to a dynamic, musical subwoofer such as the Polk
PSW-650, is robust and seamless, although even the term seamless is a tad deceptive. The reality is that
the sound is much more like "no speaker" than any $300-per-pair speaker has any right to sound.
If that sounds elitist, I apologize. I have absolutely nothing against inexpensive loudspeakers. In fact, I
adore 'em. I think the contemporary music lover lives in a golden age when it comes to loudspeaker
choices. It has become decidedly difficult to buy a bad-sounding loudspeaker. But getting to the magic that
live music possesses remains tantalizingly out of reach for almost every loudspeaker, no matter how
costly. The Maggies capture a piece of that magic, which is a trick speakers costing ten times more have a
hard time doing.
I suspect a big reason for this is that the speakers are so darn simple. There are a lot of things they don't
have: no crossover, no box, no individual drivers. As a result, there's no crossover distortion, no box
coloration, no cancellation -- which means that sound is generated over the whole panel and dispersed into
the room in a manner that is closer to the way a musical instrument resonates in free air than conventional
designs manage.
Maybe that's just my overactive imagination, but the Maggies disappeared sonically like $10,000
loudspeakers -- and even if I was using a $997 system to pull that trick off, it still seems like a bargain.
With a truly great multichannel performance, such as the Atlanta Symphony's Beethoven Symphony No. 9
[Telarc SACD-60653], the sound was literally engrossing. The orchestral sound from the front three
speakers was cut from the whole cloth -- it was rich, warm, and dynamic. The surround channels added a
subtle touch of ambience, which seems like a small thing, but it added a convincing element of solidity to
the entire experience. It transformed my 2200-cubic-foot listening room into the Woodruff Arts Center's
Symphony Hall -- truly an alchemical transmutation.
The secret of happiness is to admire without desiring
