Most accurate sub under 1,500 used


I have been looking at velodyne digital drive series and REL. The room is 12w X 23L X8H. 60% movies and 40% music usage. I am open to other recommendations as well.

Thanks

So far, I'd say a DD15 too.... or a DD18 if you can swing it.... but your room should determine which, as much as your wallet.

How much will I gain over the DD12 with the DD15. The 15 will go a bit lower to 15Hz and the 12 is 17HZ. The DD18 is out of my price range.

A lot. If you went with a DD12 you might want two while a DD 15 or DD 18 would probably be enough.
