Velodyne DD-series subwoofer

I am currently deciding between a Velodyne DD-15 or Velodyne DD-18 subwoofer for my home theater system. My room size, not yet confirmed, will likely be at least 15 x 20 feet and possibly larger if there is an adjoining kitchen and/or dining area (although there may be no adjoining area at all, so the room may only be that size or even a bit smaller or larger). The room height would be about 9-10 feet. I have a very good deal on all the Velodyne DD subwoofers, so the price difference between the subs are insignificant.

Music/HT is about 60/40.

Is there any reason NOT to get the 18" subwoofer? Is it possible it would be too large for my room? What is the smallest room for which the 18" sub should be used? How would two 15" subs compare to one 18" sub? Are two 18" subs feasible, at least for future upgrades?

I live in an apartment- it it possible to use an 18" sub without disturbing the neighbors? How about the 15"?

My equipment currently includes B&W804s and B&W HTM1, and will likely be using a Bel Canto 3-channel amp to drive them. pre/pro/surround amp is Yamaha RX-V1500, with B&W DS7 surrounds probably.

regards,
Brandon

If you are in an apartment then decouple the sub from the floor to prevent shaking your neighbors physically. Try some Aurio's under the sub, and mass load the top with some lead shot (25lbs #6)

DD15 or DD18? Awesome problem to have, I basically couldn't use my sub in an apartment before decoupling the sub. Invite your neighbors over during movie time..

at least you have concrete walls which will help! If you like it loud, then you might consider positioning the sub behind your couch (my 18" is now set that way and floated) and get a ButtKicker to get the impact of a loud sub plus the sound of a loud sub.

I would still do at least a 15 if you can afford it, you won't be there forever.. If that is not enough then buy a second one.
