Apart from the damping problem which has been very well laid out by Fons, there is another factor which can come into play and which I documented in an article in Hi-Fi for Pleasure many years ago. The fact is that many poorly constructed cables, when hit with a bit of power, will actually

Am I missing something? You send electrons and the speaker cone moves out, o.k. It comes back by itself. But surely you want it to move _in_ as well? How do you do that without positrons. (I think that's right, most things in surround sound seem counter-intuitive: So I doubt if it is positrons

Speaker wiring really is a hot topic on all audio related forums. Next time I'll use the term speaker wire instead of lamp cord. :-) For a small and inefficient Kef satellite speaker (3 with a tiny coaxial tweeter and internal crossover circuit), unable to reproduce frequencies lower that 120Hz,
