In Reply to: But those Quad-57's didn't have a lot of bass extension, right? posted by Chris from Lafayette on September 4, 2024 at 11:03:24:
Even if the panels were capable of delivering very deep bass, the front wave and back wave are out of phase with respect to each other and they interact progressively to cancel each other as frequency goes down; hence the 6 db/octave rolloff. A subwoofer could compensate for the drop in bass response, but, create a more seamless integration, Gradient thought the subwoofer and the Quad panel should have the same dipole radiation pattern. Their subwoofer is a dipole, with equalization to compensate for the 6 db/octave rolloff.
Quad 57s had other issues, in terms of sound, such as a very narrow listening window. More significant is the low volume output of the panel. If you tried to push the panels hard, not only was their severe distortion and noise, the panel would electrically arc and this created a burn hole in the panel that would progressively grow until the panel failed.
These issues notwithstanding, the 57 is a scary good sounding speaker. Very clean and pure sounding. I've heard some quite "heroic" setups, some even using four Quad 57 panels per channel to reduce the limitations of the design. These setups were impressively louder, went deeper and had better dynamics, but, I sort of like the sweet sound of a single 57 per channel.
