I picked up a pair of Infinity SM112's at an estate sale this morning. They are in pretty civil shape but will have to refoam the woofers and already have new foam ordered. I hooked them up briefly and they sound fine despite the one woofer that has the damaged foam. I will also have to do something with one tweeter that has a damaged foam dust cover and doubt I will find an exact replacement.
My question is, would there be anything wrong with just using a piece of flat thin foam similar to what the domed cover was made of or maybe a loose weave fabric??? Any of you speaker gurus have any thoughts? RM~
