Anybody prefer JL Audio or Velodyne subs for rock?

Running Cornwalls with a McSystem. I wanted to experiment with a sub. Considered the Trinity from Def Tech and JL Audio F113. Wound up with a Klipsch RT-10D for less than 1/3 of the cost of the others. May want to look at Epik subwoofers too.
If cost doesn't matter, go with two JL F113's.

I have both the SVS Ultra 13 in one room running with Maggie 3.6's, and the F113 in another home theater room(much larger space). I'm a rock n' roll guy and have to say that although the SVS is a great piece for the money, the F113 is a different animal and above it in my opinion(FWIW). The SVS is plenty for me with the Maggies in my 2 channel room(12 X 16).

I'm thinking either one you mention might be overkill with Cornwalls, if I'm thinking of the right speakers, but the F113 is a monster. Two might make you deaf!!! No, I haven't tried the F113 with the Maggies yet, since the F113's are with the home theater matched with Paradigm S6's.

I never had any Velodyne DD series, but a while ago I had a Velodyne 1012, which couldn't hunt with either of these two dogs I currently have.

I think either one you ask about, or the SVS will fill up all but a huge room with plenty of McCartney's bass!!!! Rock on and enjoy.....

I have only tried the JL F-113 and I am only using one.
It really rocks!
Fantastic intergration with my Andra 2 speakers! Deep well articulated bass notes.
Its small, has a high gloss finish like my Andra's, looks great, but is heavy as hell.

have 2 jl audio f113 in my 2ch system and one in my HT system --best sub I have ever owned--have a friend who has compared the velodyne dd18 to the jlf113 and favored the jl -113---can't lose either way --I favor 2 subs for 2ch

I really appreciate all of these great responses to my question, your information is very valuable towards helping me arrive at a final decision. The Velo dealer around here doesn't have any DD's on display, and there are no JL dealers here yet, but so far sounds like a person can't go wrong with either sub. The SVS looks like another viable option, looking forward to more responses. Thank you all for sharing your time, knowledge and listening preferences with me.
