JL Audio F113 or F112 For Dynaudio Confidence 5

I had the chance to demo both the F113 and the F112 with a C4 setup and frankly I could not tell the difference (in music). I got the 112 (notably cheaper) in my HT/2 channel system. My goal was good solid LFE for movies and a tunable sub that would help in music without having to mess around in switchover. the 112 was good enough for me in HT and like I said for music I could not tell the difference. Now the disclaimer. I listened to a variety of alternative and such but with hip hop I have no doubt that the 113 would be better. You can tell the difference in ht between the two with ease but both are stellar. No experience with dual sub setups, sorry. In a nutshell, if you want thumping bass for music go 113, if you want more subdued or perhaps slightly faster go 112. if on a budget go 112. Now I just need to fix the picture frame that my 112 knocked off the wall during ironman last week. Not a puny sub. Luck.

IMO,Rel works better with Dynaudio than JL.I tried a 112 with my C4s in the same room size.It wasnt as seemless as the Rel I have.For 2 channel Rel is your ticket with those speakers.

I'll second Missioncoonery. We run a pair of 113s in the media room, Rel Stadium III for the music system. Dialed in, the Rel is 100% seamless when paired with a full range speaker and does magical things with imaging and soundstage. The JLs are frequently noticeable, but more satisfying in the kick and room-pressurization front.

I've had zero problems getting my JL to disappear. It integrates seamlessly.

Whatever brand you get, plan on getting two. Maybe not now, but down the road. Two will integrate much better, there will be less resonance issues and so forth. Jim Smith of Get Better Sound fame doesn't even want to try to optimize a room with only one sub. Says it's very difficult to do so.

With that in mind, I'd go with the F112. Unless your room is gigantic, one F112 will do the job. Then, you'll be able to get back to getting the clone sub faster given that it's substantially cheaper than the F113. The lone F112 I have (have not gotten around to getting the clone yet) literally shakes my walls (that's not metaphorically- I have pictures on the wall that get off kilter when I listen loud)- even when it's not being cranked up. My room is pretty good size, too. 19 x 13 with 10 foot ceilings.
