I have the 950/770 Combo and while listening to the new Allman Brothers DVD I burned up one of my 630I B&W Speakers. There was literally a 1 foot flame shooting out of the speaker. The voice coil obviously burned up. Can I check something on the amp itself to make sure that it is ok? I replaced the speaker temporarily with another one. While I wait for my new driver from the repair shop. This older speaker sounds fine. What can I check on the B&W(cross-over etc.) to make sure that it is ok? I like to play it very very loud.
