Zen Crescendo or 5a...will they work in my room?


I'm looking for some thoughts here...

My dedicated listening room is 20'x 15'x 8' with the back wall behind the listening chair 4' high and opening into the kitchen area. The supported floor is wood and there is a 2' high crawl space underneath. The speakers can out from the short wall as much as need be, and proper treatment of the room will be done.

My very short list has come down to the Acoustic Zen Crescendo, and the Vandersteen 5a non-carbon. I have listened to both and could be very happy with either. Since I am a fan of tubes, I suppose the Crescendo has nosed perhaps ahead in the race, due to the fact that they seem to enjoy being paired with them. But I'm not dismissing the fact that the Vandy's woofers are self-powered, leaving the rest of the spectrum to be powered by perhaps a 100w tube amp.

Does anyone see an issue with my room dimensions when it comes to either of these speakers? Will the crawl space below lessen the chances of getting excellent bass response from either speaker?

I'd have more of an idea to what would work in my environment, but this is a new house and I've yet to put a system in there.

TIA...

Rpeluso,
You should read the original post again, he's heard and likes both speakers but is concerned with his room's dimensions and compatibility. The opinions from us responders regarding speaker preference are unsolicited.
Charles,
Yes 5as will work great in that room
Just last week we did a pair of 5 A Carbons in a 19 x 11 8ft ceiling
Their bass adjustments allow you to tune out the problems.
We nailed 24 hz flat and trimmed down any bloat at the room resonance
with ease . Their High Pass allows the amp that you love to work at its best & to be super 3D just playing the speakers in the top end.

Thanks for all the responses...much appreciated.

Rpeluso, I only wanted some input from any members that might have had some positive experiences with either or both speakers in a similar environment. As I can setup and treat the room any way I see fit, I have confidence that I can make virtually any speaker "work".

Just yesterday I listened at length to a friends Revel Studio 2's. After many years in this hobby, it was actually the very first time I had heard Revel's. I was very impressed. A slight different presentation than either of the two speakers on my current list, but excellent nonetheless. Makes me wonder how good the Salon's are.
I've been listening to speakers for 50 years and would rather have a pair of AZ Crescendo than any other .
