Newbie Alert! I've owned a Tannoy MXAV4 setup (MX4, MX1, MXC) for the last four years, driven by a Sony STR DB-1070 receiver, a year or so back, I managed to damage the voice coils on all four drivers off the front MX4s, who knows how , now my receiver, of late, goes into 'Protect' mode when I crank-up the volume into the 30s , IT'S TIME FOR A DECENT AV SYSTEM AGAIN! I checked with Tannoy UK, about a year back, for replacement drivers, and was quoted £30 odd each, I take it this is all I'd have to replace? Been totally out of the (Never have really been in ...) 'in the know how' loop, so would appreciate some advice, before spending my hard earned cash, do I get the MX4s fixed, or should I be looking at other speakers, is the receiver saying it's last goodbye's? Cheers!
