I went to check out a set of B&W 600 S3 which sounded nice when watching a movie, but when I checked out the fronts (603 S3) in stereo using a CD there was ZERO bass response, I mean my current crappy $50 per speaker setup had twice the kick these did. It almost sounded like there was a high pass filter cutting out the frequencies. When I did an A-B between these set and a similar ranged pair of Dali speakers on the same Yamaha amp the difference was immense, not only was the top end richer but they had much more bass response too, it sounded like good speakers are supposed to. I was a tad confused about the poor performance of the B&Ws which usually are considered to be fantastic speakers so I went home today to do some research. It turns out that every speaker in the Dali ranges are only 4 ohm impedance, where as the B&Ws are 8 ohm. Would this have been the reason the B&Ws were lacking so much in the top & bottom end? I thought 4 ohms took more power to drive than 8 ohm, isn't the result I got backwards? I'm not sure what the amp was rated at but is this just a case of matching the amp & speakers better? I'm going to to the only other place in town that has the B&W 600 series to check them out there, but I thought I'd ask to see if anyone can come up with an explanation for my experience.
