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,
spacekadet

I can put my hands on each driver simultaneously
and feel them vibrate at different times on the same tracks. I suppose the subs only think their receiving a stereo signal as well. LOL
I agree with Mcreyn and some of the other guys. No doubt about it two stereo subs are very easy to discern from a mono sub or two mono subs.Infact once you hear it ..all your questions will be answered.
Yeah..no need to bother if you can't hear the difference.Just enjoy the mono string plucks.:-)

Good listening
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!
[email protected] and Truthspewer remind me of the Borgs from Star Trek. When they say " Your resistance is futile".

Just because we do not want to play in you guys sand box. You get upset. I'm here to tell you ..It's alright.. there's plenty of sand boxes for everyone!!LOL

I'm sure you'll find some more folks to come over and play in yours.Now go back over there and make sand castles.:-)
Oh yeah don't forget to take Truthspewer with ya! He said he was outta here days ago! I think one of the other kids threw sand in his eyes.Because he hasn't found his way out yet!
Opalchip you come across like the cock of the walk with the tone of your last post. Tell you what my friend..how about you turn off that subwoofer. Use only your fullrange speakers, take one and cut it's low frequency extention off at 65 Hz. Listen to some well recorded full scale music in stereo.
Come back and tell me you can't hear an improvement running both speakers full range in stereo. I'll tell you.. you need to find a new hobby!

I've read some of the scientific papers you touch on. But it still can't explain what the human ear perceives as a whole.If everything you say is the absolute. Maybe most of us only need one full range speaker and a matching monitor.. since we can't distinguish mono from stereo bass any way.

What kind of bass are you talking about? Acoustic Bass,synthesized crap or movie bass.
Quick quiz ..have you ever tried it? Most of the nay sayers are the same people who have never tried stereo subs. Also you've forgotten the Piano goes deep into the 20 Hz range. Oh I forgot the Piano's not a musical instrument either... right? Or you'll give me your theory on why I or anyone else shouldn't be able to detect it's presence in stereo..right.

What if I had 3 bassist in the same recording from left to right. You trying to tell me the stereo subs can't differentiate between the right and left player? Even at the lowest frequency of 41 Hz. I've already tried this using indentical subs. Both subs responded at different times depending on who was playing. Apparently there are recordings with the lowest notes in stereo on some cds.

It's possible to have this in a movie track. Why do you not believe it's possible in some other recordings? I guess some people know more than the engineers of Lexicon and Meridian who have mutliple sub outputs just for such a thing.

Next thing you'll tell me is that bumble bees can't actually fly. Because there's not a shread of evindence that suggests otherwise. Me and 4 billion other folks just imagine seeing them fly ..right.
Opalchip...LOL..I really enjoyed getting under your skin.
No doubt your very brilliant. It's been a pleasure.My only point is, I as well as others enjoy what stereo subs do for the music and movies.Thanks for all the great info.Will it stop me from ever using two subs again..not hardly. Just like a die hard tube fan, we all have our preferences whether anyone else likes it or not.
It may not be sane for some.But hey there's nothing really sane about the hobby anyway.Lighten up.. it's only audio.

Good listening!
