Hi Bob.
Lately I've heard some very good subwoofers from Yamaha, Velodyne, Polk Audio...but I like very much the bass from my JBL subwoofer and don't think it is only good for techno and movies. Pink Floyd's "Dark Side of The Moon", on sacd, sounds fantastic on the strongest bass till the most delicate passages. "Fantasia 2000" Firebird Suite, from Stravinsky, is very impressive and it admires me the power and precision of the low frequencies from the JBL on this track from the dvd. I have many other examples that would make this post too long.
Like fingerprints,no one have the same hearing like another person. I respect your admiration for Yamaha and Velodyne subwoofers. They are really great.
Best Wishes,
Gerald
