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

Cant say I'm an expert here, but I recently moved, and have my system on concrete floors/walls. I have placed the boxes to my equipment behind my gear (hidden behind a very large tapestry), I have 2 squares of carpet under each main speaker, and finally some homemade sound panels directly behind each main. I am happy with the response from my mains, and think the bass is damn good. I'm sure every room is different, and equipment acts differenly in each room...but hey, if a salesman wants to actually sell you a less expensive piece, I'd say try it...worse case, exchange for the higher end piece.

Also, my speakers are on spikes...After reading a few other responses, I feel this is important to note!!
