Vandersteen 3x Owners: More Bass?

The room is 30' Long x 14' Wide. The walls are irregular shaped solid stone. The floor is carpeted concrete. THe ceiling is exposed wood beams (about 9'). The speakers are 10' from back wall, 3 1.2" from side walls, and 9 feet from listening position. I think I have followed most of the recommended practices for avoid major positionj problems. I like to have the main speakers as far out from the rear wall for best imaging and apparent depth.

What electronics are you using with the 5As? I heard them at the dealer with ARC REF2 and some solid state amp (Plinius?). They sounded excellent. It does raise the issue of buying 2Wqs now, or save for a year or two forthe 5As. Word of mouth has it there is a 10% imprvment over the 3a + 2Wq combo for over twice the price, but of course in sector of diminishing who would not pursue that extra 10% - frankly, 10% better sounds like alot of improvement at this level.

Your room and setup sounds ideal and not too different from my own. My room is 18W by 30L by 11H (with cathedral ceilings). I too have positioned the speakers out from the back wall and listen in the near field.

The advantages of the 5As over the 3ASigs/2Wqs are many:

Better mid driver, and better cones.
Total seamless integration of speakers and subs.
A 400 watt amp with plenty of reserve.
Fully adjustable in 10 bands to flatten response.
Adjustable level and Q.
Less total furniture and a better looking speaker (WAF).
A cross-over that unloads the amp and thus cleans up the highs.

I don't know about your 10%, but this combination can't be beat at this price in my opinion.

I am using an ARC CD3, an ARC LS 25 MKII, and an ARC VT 100 MKIII. There seems to be a great synergy with ARC and Vandersteen 5As, and I am running all balanced. Without going into too much detail, I have good image height, width and depth, good separation and definition within the image, no apparent digital grain or harshness, and a roundness to the vocals. I have auditioned both the 5s and 5As in the same room with the same electronics and the 5As are a distinctly obvious improvement on both the top and bottom.

All that being said, the 3ASig/2Wq combination is very good and very reasonably priced, and would raise your current performance. You could go this route with the 5As in your future and have little trouble turning that equipment over later via AGON.

Zargon, thanks for the input. The 5A path seems right. One thing I like about Vandesteen is he has a design philosphy that he can articulate (on speaker boxes, on subwoofer integration, on multiple drivers covering the same frequency. on time and phase etc). Not only articulate, but one that has been consistent for 20+ years. Also a reason I like CAT equipment.

It sounds as if the 5As have some type of equalization programming to improve the bass/room interface. In some of the material I have read, the argument for using of subwoofers on corners for best room/bass acoustical interface seemed to make sense (the ideal location for mids and highs is not the same as the best location for producing bass). Also the the idea that having the subwoofers in a separate box would improve the on the deleterious effects of low frequency interference with the mid range and tweeter - I assume that some of the additional cost of the 5As is dealing with implementing a mechanical engineering solution to this problem.

The strength of those principles suggests that much of what went into the 5As (besides better drivers? crossovers? and fine cabinetry?)are electrical and mechanical solutions to inherent problems resulting from all the drivers being in one box. It sounds as if Richard succeeded admirably while producing a speaker aesthetically better suited for most rooms. I would think if the 5As sound better that the 3A/2w approach it would be due to better parts and tolerances, as "natural" principles seem to favor the use of dual separate subwoofers as a solution to some typical speaker design problems and compromises.

While I agree that the location for best imaging and the location for best bass are in geneneral not the same, in my room they are not very far apart and the controls on the 5A easily corrected for the difference. (Only the bottom two bands were adjusted slightly for flat performance.)

The additional controls on the 5A sub seem to overcome the advantage of physical separation as in the 2Wq. There may be problematic rooms where this is not the case and separating the subs might help, but I would imagine additional solutions would be needed as well.

Since Vandersteen has designed both separate subs and integrated subs I suspect he fully appreciates the pros and cons. I find the 5A subs to be the best integrated and best sounding subs I have ever heard. They disappear along with the speakers leaving a naturally distributed sound stage. So for me they work very well indeed.

Well it certainly seems like you have a very satisfying system. Has the search stopped? or are you contemplating your next move? Any thoughts on interconnects, speaker cabling, or power conditioners within the context of your system?
