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: I'm not against your advisors that convince you to one sub instead of your original and correct idea of two subs in a stereo fashion.

The integration of subwoofers in an audio system is not only for abetter low bass performance: far from this, please read these links about:

Amazing how strongly some (Truthseeker - funny handle...) confuse opinions with experience. I was skeptical about multiple subs. My neighbor considerately lent me his sub to pair with mine, and the reponse was better - smoother, more toneful, more texture, less nodes. Multiple subs placed symetrically minimize room nodes effects. Multiple subs are NOT about more bass. Also, subs are NOT omni-directional. Try turning off your mains and running tones through your sub. Believe it or not, you will hear the sub above 200 Hz! And mine is an active 24dB/octave crossover at 60Hz.

There is so much BS on the Internet passed off as fact, by punters who never bother to learn for themselves. Warning - too much time in these discussion forums is dangerous to your audio health ;-)

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.
