one went about a year ago and a replacement was purchased from a B&W supplier. now the other one has gone, and it seems the parts are no longer available :( we're looking for a direct replacement, or a pair from another speaker that'll drop in to replace both. we've got the tweeter out of a 601 to try, but, it's not exactly a drop-in replacement, and some work will be needed to make it fit. perfect opertunity for an upgrade ;) but a proper replacement would be great.
