Velodyne DD: 10 or 12?

Thanks Theo, Rwwear. Theo, if I read between your lines too much it might look like even a DD10 might work for your room. It does not seem as if you tried it or even would be inclined to. What do you think you might gain from two DD10s? As I understand it the two 10s and the one 12 have roughly equal surface. I do understand about the stereo subs though.

Cmach, good info and thanks. I guess I was posting at the same time you were and did not see your post before. I am leaning more to the 12 now. More input is welcome of course!

Anyone, does the black finish wear well? Is it susceptible to fine scratches, etc? Some of those things are, even when handled carefully.

Thanks everyone. I think I am almost ready to pull the trigger on the DD12. I do have one question though... I ran a frequency sweep of my speakers with the REL off. While I did not record the results exactly, the things that stood out were:
1) Bump of 4-6 db between 80-95 hz
2) Small dip in the mid-to high 100s... maybe 170 hz? Do not remember and I cannot confirm right now.
3) Rapid rolloff from 55 hz down, to about 6 db down at 40, pretty much nothing there after 37 hz.

Also, I am running an integrated with a subwoofer out feature, which is placed AFTER the volume control (so the SW follows the amps volume). With the REL, I have been using the high-level (Neutrik) connections out of the amp's speaker posts so I have not had to worry about any of this.

Given the points above, is the DD still the way to go to correct all the bumps and dips, and will it do all it is made to do using the connections I have now? As you can tell, I am a bit illiterate when it comes to advanced SW connections, not having had to do so for a while. I am not a technophobe, and am sure I could learn how to set it up, so that is not an issue. But I just want to be sure, before laying out cash, that I can realize the full potential of this impressively-spec'd machine.
BTW, I will be using the sub in a strictly music-only, 2-channel system... does that change any of the answers above or any to come? Sorry, should have stated that earlier. I do like the individual settings feature, so I can use a different one for rock, classical, etc.

Hi, just giving this a little bump... would love to get some answers to my latest set of questions above. Thanks much.

Thanks again, guys... getting close now... I have a specific question. My mains go down to 40 hz... is this overkill for such speakers? I am also confused by the 80 hz crossover point as mentioned in reviews. Does this mean that if my mains have a dip in the 90-110 range, I cannot use the DD to fill in that dip? I see the spec of 200 hz but am having a hard time reconciling this with the previous fact.

I should note that I am quite happy with my Strata II in terms of depth. But because of my wood subfloor, I think I am getting some reverb that might not exist with a forward-firing sub such as the DD, plus I would like to correct for the room anomalies *above* the 80 hz point.

Sorry for all the questions. You all have been great with providing info. I am planning to call up my fave dealer tomorrow and get this wrapped up but would like some reassurance as to the above.

Hard to swallow but I am still on the fence. I spoke with someone at Velodyne and he said something along the lines of "10 and 12 are toys". I believe this has been mentioned before on AA or here so no secret if I say that. How much if this is marketing boost for the 15 and 18 and how much is truth? I cannot stretch to the big boys but do not want to get a 'toy' for $3K.

Also a question regarding vented subs like my REL. From an ad for a closed sub: "Vented systems are usually unsuitable for music because of port noise, low system Q (that causes bass overhang), and phase issues at resonance frequency."

True? In general, does a closed sub make more sense for a music-only system? As you can see I am very much still climbing that learning curve of subwooferland.
