That's an interesting claim. How do they figure that? Well, I guess I'll just have to hear it...
dave, what speakers are you running now?
If you've never heard Dynaudio than it's hard to believe. Sounds like marketing hype, but its not. Dynaudio bass is a game changer. I used to have a pair of Dynaudio Excite X12s which is a tiny bookshelf speaker with a 5 1/2" driver. This tiny speaker can shame much larger speakers, even some floortanders in the bass department. Its mind boggling the first time you crank it up.
Here's what Robert Reina said about the bass of the tiny X12 in his stereophile review:
"At the opposite end of the frequency spectrum, the Dynaudio dared to dazzle. Tiny speakers—even ported ones—aren't expected to produce dramatically realistic bass in my large listening room. But with all the rock-'em, sock-'em Blu-ray discs I threw at the X12s (my home theater is integrated into my two-channel reference system), I kept looking around the room for the subwoofer that wasn't there. It didn't sound like that fake upper-bass bump that makes you think it's deeper than it is. Nor did it sound like that farty, discontinuous, "port-like" chuffing bass. No, it sounded like real bass even with the Schwantner disc, when Glennie plays the bass drum during the high-level intro to New World in the Morning. And on Crispell's Amaryllis, Gary Peacock's double bass was prominent, lifelike, woody, and linear throughout the instrument's range. "
