The Ultimate Subwoofer (BD-Design)

Hi Peter,

Although the above would be true by itself, it is kind of unrelated;
The low frequency waves just *will* move the diaphragm (Swings' woofers),
even into areas they shouldn't. If that wouldn't give distortion by
itself, it will give electrical feedback.

At second thoughts it became clear to me that this is what Mike was talking about...

Probably no big deal, but something to think about anyway. And just
interesting ...

I can be a big deal if the amplifiers are not able to control this "feedback" enough (EMK is this called if I remember correctly) which then will disturb the accuracy. No worries with the CrazyA's or the Ultimate Subwoofer though but the bigger the receiving diaphragm and the lower the damping of the speaker system (high Q) the stronger the effect....
