Hi I just aquired a set of Sound Dynamics 100s speakers but the woofers surround foam is gone. Is there a replacement I could use or should I try putting new foam on? Has anyone tried putting new foam on before? The box is ported - 3"*12" long; 0.94 cuft.(internal dim-8"(d)*11"(w)*18.5(h)) He said that he was using them one day and then the foam broke up and he stopped using them, I'm assuming that the rest of the woofer is still good. It is a two way speaker system sporting a 10" woofer. The guy I got them off said that they were guaranteed for life but as we all know Sound Dynamics is long gone...he also said that they sounded pretty good, though he is no audiophile(not that I am also).:wink: UpDate: I just came across this 10" http://www.partsexpress.com/pe/showd...ID=16243&DID=7 Would this maybe work? Any suggestions?
