Best Big Sub? or duals?


I just moved and my HT is a 25 x 30' room in the basement with concreat floors. My current sub a vandersteen is to musical and just not big enought to have any effects, I also have a 15" velodyne that just about cuts it but doesn't really shake the room and the sweet pot is to narrow, probably because of lack of power my old house this did great in. I am using all vandersteen speakers so they are really fast I need a good fast sub or two that will shake the room. Any sugestions cost is not a big issue just want to do it right and don't want to spend more than I have to.

Parts-Express has the Titanic subs and a few of them use the Dayton Reference drivers.These probably aren't necessary ,due to being used strictly for HT.I use 2 subs,each with two of the Reference 10" and the IB woofers for LFE.They have on sale the D-dub kit for $320.These have 15" woofers mated to 240W plate amps.The Titanics are about $750 each,though they do have 1000W and a parametric EQ.
Is that the Nelson-Reed top of the line where he used ATC midrange in the mains and eight Volt 12" woofers in a pair of subs? I believe he claimed 120 db SPL at negligible distortion...WOW.
I use a Bag End Infrasub 18. Very nice reviews. Wish i had room for two so i could have one next to each speaker. Excellent IMHO. Don't know if this is out of your price range but i saw a very nice one used a week or so ago for around $900. A very unique and great sounding sub. Good luck on the down low.
The best sub I've ever heard was the jl audio gotham. Musical, acurate, fast, goes as low 15hz, and has as much slam as a concert at a coliseum. Probably a fathom 113 would do the job right but if you want overkill the gotham is the way to go!
