Hey, after about 6 months of use, my Tapco(Now Mackie) Thump TH-15A's seem to be a bit blown. On some frequencies at high volume the bass distorts and one of them emits a very high, low volume whine. When I emailed them about warranty they said "If they find the voice coil of the speaker to be burnt or torn, or somehow non-defect, it would be a non warranty repair."
Does anyone know if this would be the problem or if it's (hopefully) something different
Thanks, Misha
