And assuming you have a good clean powerful amp, Tigs, those Kef's won't distort if you play them loud?
How much power per channel do you look for in an amp?
The specs look great for the subwoofer. In the old days, they couldn't really get low base ie 30 hz, so they boosted the power at 80 Hz or something like that. Sounded like shit or pretty much the same as the loud thump thump systems in cars.
If you recall the movie Apocalypse Now, the theaters actually had a special speaker for the low base in the scene with the Napalm. I actually had one of those woofers. It was 4 ft x 4 ft x 16 in or so. I could make the neighborhood rumble but it was that real low base.
Or do you remember the Klipsch Horns:
They could really put out some low base because they used part of your house as the horn design, but the upper end sucked because they put another horn in there for that so it sounded like a loudspeaker.
