EuroLive B115D



I have had my 2 EuroLive B115D speakers for a few years. i love them. just the other day i went to turn one on and the top speaker part (called 1.35" compression transducer in the manual/brochure) is not producing any sound only the bottom half of the speaker. it sounds like as if there if a cloth muffling the top speaker part. Does any one know if i can fix this at home somehow or not where i could buy a part to fix it? Thanks.
