Bass Response and concrete floors

I was talking to a Dynaudio dealer the other day and asking about the Confidence 5's in comparison to the rest of the Dynaudio line. The 5's are apparently being cancelled with two new models being released in the Confidence line, based on the Evidence technology.

Anyway, he asked what type of flooring the speakers would be on. I said concrete with thick pile carpeting. He said the bass response on a concrete floor, even with carpeting, would be muted, that the Confidence 5's need a floor with give to produce decent bass. He said that the bass would roll off around 50 Hz on a concrete floor.

I've seen so many very positive comments about the 5's, but I suppose that people who are satisfied may well be using them on a main floor built on joists. The dealer indicated that I'd be a lot happier with the 3's on my floor.

Anybody know why this would be? More importantly, is this a common behavior of floor standers on concrete floors? Is it a general "rule" that if you have concrete floors, you'll get better performance from a high quality monitor? Thanks for any info -Kirk

Concrete is the BEST floor to have, period! I've lived in seven different houses and the best sounding room by FAR has been my concrete floored room (carpet covered). The inital transients are better, the decay is much more deliniated and the overall sound is way more real sounding. If you add a serious subwoofer to a concrete floored room, look out! You'll be floored (yes, pun intended!) by how well the bass couples to the room.

I think there are way to many audiophiles that are used to feeling the bass through their feet and their asses, and somehow think this represents "better" bass. IMHO they are dead wrong in their advice when they "dis" concrete.
