I'm not sure if this has been already posted... While killing some time at GC today I tried both the SUB SB4 AND SUB Ray4, $279 and $299. First thing I noticed was the weight, the SB4 was noticeable lighter in weight which I really liked but it seemed to be a bit lighter in sound as well, where the Ray4 was slightly louder and punchier which I don't get since everything I read about them claim to have the same electronics. The GC staff seemed clueless about this. Any thoughts?
