Hah, I actually like the way these sound. I totally understand why others think they suck. You may not remember, but I told you I didn't think you'd like these a while back purrin lol.
Not to keep parroting myself, but FAD did have a specific sound in mind when they made these. They wanted them to sound like really old horn speakers. They did a better job on their successors, the 1602 (aka "Piano Fortes"). Those who are trying to imagine how they sound... telephone line is kind of accurate in a way.
It doesn't help that the fit on these is atrocious and screws up the sound even more.
