I am considering a Velodyne DD-18...

...to complement my Joseph RM25 siII speakers. When I went looking for speakers with more bottom end the dealer who sold me the Josephs said that in my room, 16'X13'X9', I'd have trouble with resonations. He suggested that a sub that could be tuned to the room would give better results. After much reading, I'm gravitating toward the dd-18 but I have heard it said that a smaller room may prefer the dd-15. I assume that the dd-18 will better reproduce the very, very bottom end and that the equalizer eliminates the issue with the room size. Anyone have opinions on the above? Thanks for any replies.

The issues of room modes will remain. There are basically two ways to deal with them:
1. (re)positioning speakers and/or listener to avoid the worst spots
2. acoustic room treatment to tame them

The EQ on the DD-subs is an excellent one that will help in any room but it cannot fill a (bottomless) null.

BTW, the DD-15 should be OK in that room, if you treat it right. ;-)

I have a DD-15 in my basement and it's set to 6 or 7.
The DD-18 is most likely more than you would ever need.
