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 describe the look of the cones). Are they worth anything? Also, I believe they are supposed to come with a pair of boxes with 18" drivers as well...can anyone verify this? Furthermore, if they are worth keeping, does anyone know a decent amp to pair them with? Much appreciated
