Velodyne DD's flying out of owners' houses


I've been watching the subwoofer listings for a couple months now, and notice alot of Velodyne DD-series units being listed. Normally when I see that I think poor price-performance ratio, but I've not seen anything critical of the DD series in print.

Sure, each seller typically lists a reason for selling that seems to indicate an issue other than unit performance, but the sheer number of units being listed makes me wonder about the price-performance characteristic. Anyone have thoughts to share on this?

Drubin - You can set up the Veolodyne in each way you described. I go preamp -> sub -> amp -> speakers. I find the that the sonic gains of high-passing my speakers outweigh the loss of transparency by having the sub in the chain.

Though - if you dont want to mess with the "architecture," just use a preamp output, or run another set of speaker wires from your amp to the sub. You can still do all the room correction with the sub hooked up these ways.

for 17 x 23 x high ceiling, you would want the 15".

for 10 x 16, you want the DD10.

For sub sizes, room volume is everything. If changing it between rooms a lot is a must, go with the DD12.
Thank you!

Have any of you DD owners also owned REL subs? How would you compare their strengths and weaknesses?
Drubin -

I did an exhaustive sub exploration before I ended up with the DD15 that I chose.

I brought a Rel Strata III home (their tightest sub), and I liked it a LOT, but room integration issues... you know how they go. I would have bought it if I didn't encounter the DD series...

I would say that the REL Strata is a HAIR more musical than the velodyne. The bigger subs probably less so. Definitely neck-and-neck here. I am defining musical as: (hi Mr Tennis) tight, articulate (hear notes, not frequencies), and "disappearing" ability.

But - with the Velodyne, you get:
* room correction (this is the deal breaker for me) with auto room-eq ability
* high pass (don't think the rel has this, I may be wrong)
* ability to feed a mono signal for running 2 subs in true stereo
* remote control
* ability to change "profiles" with 1 button. I have different gains,slopes,crossovers, servo settings for:
-> music (rap/electronic, rock, classical/jazz)
-> moves (drama/comedy, action/loud)
