Velodyne Digital Drive Series subwoofer in stereo



Hi, I've been very interested in running two subwoofers in stereo (diff. signals to each subwoofer); I've heard many people swear by this setup.

My next room for my system will be 14' x 14' x 18' high ceiling loft living room. My question is, will two DD10 be enough to fill the room with organ music and scare me out of my seat for movie tracks? Should I move up to two DD12s? Money is not really an issue, but I'd like to save wherever I can.

Any help would be appreciated. Thanks,

Dear Spacekadet: Why I already say that you can loose music info. With a pair subs you have stereophonic sound reproduction that is exactly how its happen at the recording event.
Example, let's take a low drum that was recorded at left side of a music hall : if you have a dual mono subs ( left/right separates ) you will hear that drum at the left side on your audio system but if your subs are sum up ( left+right ) you will hear that drum at the center of your audio system.

Regards and enjoy the music.

Possibly the difference between one or two subs is non-quantifiable. I certainly heard a difference when I added a second Vandersteen 2W sub to my system running in stereo. I believe I hear quite well the stereophonic effect of the low frequencies. The room certainly fills with low sound better than with one sub, and there have been no problems with nulls that I'm aware of. Currently I have ten 8" bass drivers operating and simply the presence of the additional drivers makes exceptionally deep frequencies audible. Previously, when I operated two subs (with six 8"drivers total) an incredibly low bass note was not even audible. With the addition of four more drivers it could be sensed.
Dear Douglas: +++++ " . I believe I hear quite well the stereophonic effect of the low frequencies. " +++++

The stereophonic effect: I tottaly agree with you and that issue is all about the use of two sub's instead only one.

This whole stereo sub thing is nonsense. Hardly any info there. Hardly heard. If you can detect a difference, it's because there are now TWO subs in the room instead of one, and the strain on the single sub will now be halved. It's the transients you hear first when it comes to bass, and those transients are almost always located above the crossover point..ie..in your mains. The ONLY possible way you "might" be able to increase the "spaciousness" in your subs is if you physically locate them directly to the sides of your head (ala Lexicon pre-pros)...and even THAT is of dubious benefit. MUCH research has been done on this. If you really want to improve the bass, yeah, buy two subs...but DON'T bother running them in stereo. Either stack 'em or spend a LOT of time and effort situating them properly.
Done
Truthseeker if you haven't tried this in your own room what you speak is nonsense.LOL

"If you can detect a difference, it's because there are now TWO subs in the room instead of one, and the strain on the single sub will now be halved"

I'll be damn you answered your own question. If there are two working less than one..you have lower distortion correct. I've not heard a single speaker that could create a stereo image all by itself. If you have please let me know. :-)
Think of the money you could save by only needing a single speaker!WoW

Have a great day!
