"Voice coils of God", that's exactly what I've read for all the time best products of B&W on WhatHIFI's site. I got a pair of Β&W 601 S3 to see what was the hype all about them.
Well, not impressed for being the "voice coils of God"...
As I've heard from others, I agree: Recessed mids and boosted high frequencies. I would say nice for background listening, even the highs being boosted.
Some people think they need 200watt amps (!) just for headroom to drive them at their best? Those people also propose to drive them with PA amps... LOL.
