Morning all. Ive got a bit of a problem! I have some oldish (probably about 4 years) mission 780s which were made redundant about 3 years ago when I bought some B&W 603 S3s. I decided to get the 780s out from the loft for use downstairs with a cheap amp from Richer Sounds. On connecting everything up I was a bit startled to find the low end doesnt seem to be working (when bi wiring). I thought it may be the amp (Cambridge Audio A5), so swapped it for my Arcam A85 (which should be more than enough to power the speakers). But still no joy. . Has anyone had any similar problems? They have been in the loft for a couple of years but can imagine this would cause the problem - Ive also taken the backs off the speakers and everything looks ok (admitedly I havent put a multi meter on them or anything yet). Any suggestions greatly appreciated. Thanks James.
