First, let me thank anyone who posts a reply for your knowledge, insight and willingness to help. I have a pair of Wharfedale e.seventy floor speakers. The bass driver in one has some problems with the dome insside the cone and sounds muddy. Have found a company that does re-cone, but want to know if anyone has had luck with replacing the driver. Older model speakers (first intorduced 1977) but still love them. Anyone else have these speakers or know where I can get a replacement? Thanks again.
