The plastic bass driver domes on both of my Quad 12Ls have become deformed and generally finger-inprinted in a child related disaster. To my ears the mid range sound now seems rather muted and lacking the air there was before - though for casual listening the speakers remain fine. Clearly this damage is gonna need major expenditure to put right. The question is though, what to do? I am driving the speakers using a Quad 909. Is there now anything better out there than the Quad 12Ls that might qualify as an upgrade of my system? Any suggestions? The alternative is to either buy a new set of 12Ls and use the damaged set in a less serious role, or to get the bass drivers replaced (I'd imagine this might be very expensive!). And of course I will be sure to super-glue the guards on to the new speakers!
