Rauliruegas,
Good link. I did not read the entire thread but I realize that I do share your views about the terrible amounts of distortion from typical bass in both subwoofers and most speakers. This is why I recommend large woofers with large motors with large diameter voice coils working with a short coil in a large magnetic gap (the most linear type of woofer). I did not mention it above but the vast majority of woofers are the lower cost small diameter long voice coil in a short gap and which means they are pretty much non linear over their entire operating range and resulting in highish amounts of IMD distortion and harmonic distortion.
However, I think this goes far beyond the simple request of Ziggy and don't want to divert us from that goal but nevertheless I agree with you wholeheartedly.
