Help with sub upgrade

I have decided going with Jl subs but need further thoughts. I want to start with one sub and see if that would suffice? would a single 113 be all i need for the room. (mostly movies). If i started with a 112 would i quickly want a second? Two 113's seems to be overkill. The 112's are more appealing in that they are a bit smaller and they are a bit lighter.

If you have to put a sub in a cabinet I would think the JL would be one of the best. The JL cabinet is built extremely well. I also found that the F113 takes a while to break in. That driver they use needs serious exercise. They sound excellent right out of the box but are much better and smoother after some good use. I would go with one F113 and then try and pick up another down the road if you feel the need.

JL's are a fine product for sure. If I were considering a cabinet placement of both subs room EQ would be a big concern to me. JL's have an OK set up system but I would suggest the Velodyne SMS EQ component or simply going with Velodyne subs.

As to which brand gives the better low end is almost a toss up. I had some time with the JL 113 and my DD18, using their own EQ set ups I prefer the Velodyne. After the JL has been EQ'd via the Velodyne it's very close. The JL build quality is a bit nicer than the Velodyne which means nothing after a short time.

One on one in my room I prefer the larger 18" coned Velodyne by a very slight margin, my preference really. Using both at different ends of the room really seemed to lock or tighten up the lows in my room. In hindsight I should have gone with two 12" subs. Keep in mind the EQ is everything IMO.

Even with modern HT room correction EQing the sub/subs prior to running the room correction program is important IMO. In my HT the sub settings are just a little hotter for film than music, again my preference.

Just installed dual 112's and not looking back. Thanks for the input.

My thoughts...I have a full Paradigm Signature S1's,C1,ADP1's with a SVS PB 13Ultra and it sounds incredible. I just purchased a HIFI Pyon subwoofer platform custom fit just for the SVS to raise the sub because it sits too low to ground, also to fine tune the subs overall performance. And that it has done....For the price of a PB 13Ultra and a SVS AS-EQ1 subwoofer equilyzer you would only get one JL F113. And from the reviews of this worlds best sub EQ, the Fathom wouldn't even come close to the bass performance of the SVS & EQ. Even two PB13 Ultra's + EQ would kill 3 JL's in my opinion.

My alternate choice:: Check out Paradigms new Sig Sub 25. Apparently it's a great sub with a big price tag....Great reviews online.
