Hi all... I have just cracked my Mission 732 cones after inadvertently hitting them with some "Manson" and forgetting to dial down. I notice that the cones are so brittle, and cracks run around just by merely touching them!I love these speakers, and apart from the now rapidly deteriorating co...
Dying speaker cones.

Hey guys, i was given a pair of vintage Kenwood LS-P9000X 400watt speakers, does anyone have any idea how good these monsters are? The 10" drivers need re-rubbering, but the cones look in all honesty like they are made of carbon fibre (i know that's ridiculous, I just don't know how else to descr...
