Home Speaker Asylum

General speaker questions for audio and home theater.

Re: Who owned Maggies and went back to non-planar drivers?

205.188.198.22

Every large planar speaker in my experience has some band of frequencies (set-up dependent) where the big spacious soundstage behind the speakers collapses and the sound appears to be much smaller, and coming from right on the panels themselves. Maggies, Sound Labs, Acoustats, Martin-Logans, Audio Statics, Sound Labs, Apogees, Emminent Technologies ... every single one I've ever heard. I find this effect very annoying and, therefore, have never plunked down the green for a planar.

I think this is a combination of several factors: 1) Beaming when the frequency wavelength becomes shorter than the panel size, 2) dynamic constriction and/or distortion as the panel nears its excursion limits, and 3) some combination of comb filtering effects or lack of integration between multiple drivers.

I have not heard this effect from Quad 63s, designed to mimic a point source, or from true line-source drivers.

I lived with a well set-up pair of Maggies for about two months, and I've chosen not to return, despite the many appeals of planars.
