Velodyne Digital Drive Series subwoofer in stereo

Truthseeker, not to argue...but I my understanding is that there is indeed different information that is sent to L/R subs when run in stereo. I may be wrong about that.
I know that my system (using Vandersteen subs) does not simply make a dual mono presentation. They are literally receiving only L/R signals. Are naysayers suggesting that in all recordings there is never low hz information sent to either left or right, but only both chanels? This may be, but I have never heard of it.
I have listened for years with one sub, then added the other. Whatever it does, using stereo subs alters the listening experience, especially since (and I don't care much if it's technically appropriate or not - it sounds great) the subs are directly behind the main planar speakers in the front corners of the room. To me, it's the ultimate way of integrating the subs with the mains.

Perhaps Truthseeker has not had experience with a high end system using a pair of properly integrated subs but the difference vis a vis a single is quite pronounced. I would suspect most audiophiles that have switched from a single sub to a pair will testify to this.

No question about Wc65mustang.

Dear friends: THis is a very interesting link about the subwoofers number that we need.
This link was posted by Skushino on other thread. The conclusions are on the page 28, yes is a long history:

Folks, as it so happens, I had a pair of Velodyne HGS-10 subs. Yes, a PAIR. I experimented with many locations...stereo, opposite walls, 1/3 wall, staggered, etc. I ended up stacking them and placing the stack just outside of a corner. Even played with a Behringer (very difficult learning curve).

Gmood1, what I meant to say is that there's hardly ANY out-of-phase information in the low bass regions where subs operate, and even if there is, it's NON-DIRECTIONAL...ie...it makes no difference. There is NO imaging at frequencies that low. If somebody thwacks a 50hz bass drum note, the imaging will come from the over-80hz transients located in your MAINS, and not the sub.

And btw, the Velodyne HGS series play with undetectable distortion in the first place, so the addition of the second sub served merely to increase overhead. The pair of HGS-10's has been replaced with a single DD-10, which will soon be upgraded to a DD-12.

Wc65mustang, my system is indeed high end enough to be able to discern a difference IF there was one. There wasn't. And my subs were as properly integrated as experimentation allowed. If I should ever decide to experiment with two subs again, I'll have YOU come over to demonstrate your special integration skills, but only if I can blindfold you to see if you can detect a difference. :)

On 99% of cd's, low bass out-of-phase info just isn't there...period.
