In Reply to: Re: Room size Vandersteen 5 & 5A vs Quatro posted by TaP on March 27, 2007 at 10:14:08:
My room is similar to yours in size (lower ceiling) and I have a similar dose of room boom between 40 and 50Hz.I borrowed my dealer's Quatros for an eval. With the bass contours set flat the major room mode was a good 12db higher than the adjacent frequencies. With a bit of tweaking of the crossover controls I was able to get the delta between frequency centers down to about 3db without any trouble at all. Keep in mind that Vandersteen recommends against using the controls to create a perfectly flat response. Rather the goal is to reduce the size of the peaks and troughs by an equal percentage (75%).
The bass out of the Quatros is impressive, but they still lack the ability to pressurize this room and provide "impact" with deep bass notes. The additional bottom end of the 5As should solve that issue... so that's what I have on order.
Since both speakers provide solid bass well below the 45Hz hump that you have in your room both will have equal ability to excite it. The bass contouring controls will allow you to effectively flatten that hump and hear/feel bass like you've never experienced.

Can you share the reasons that you have chosen the 5A's over the Quatros?One significant advantage of the 5A's is the appearance...I would love a pair of 5’s or 5A’s in Birdseye Maple. The Quatros are to me the most visually attractive of the lesser Vandersteens...narrow and deep ass opposed to wide and shallow.
I went with the 5As for three reasons....1) More bass weight in the 5As
2) The 5As have a quality in the midrange that I just can't describe. Every time I've heard them I've been amazed at the fact that I'm too busy listening to the music to bother with any of the audiophile analysis. The quatros do this too, but to a lesser extent..... and the MOST important reason ....
3) WAF --- My wife HATES floor standing speakers and doesn't hesitate to comment on how ugly they are. When the Quatros landed in our living room there were no comments at all. Eventually, I got a "not bad," and "they aren't as gaudy as the Wilsons." I took her to the home of a local 5A owner and she nearly caused the end of the Universe with, "Wow!! Those are beautiful!" Go figure....
It's exposing her to the Wilsons that did it.Not just the question of physical appearance either, expose anyone to the sound of Wilsons and they will marvel once they hear 5As!
It was actually kind of funny. She came along to look at the 5As... literally... she just wanted to see what they looked like in person.Since we were in one car she got to sit through a 1 hr listening session with me. Definitely had an audiophile experience with constant comments like:
"I heard things that I've never heard before!"
"Look, I've got goosebumps!"
and the all-important....
