JL Audio F113 or F112 For Dynaudio Confidence 5

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.

Which REL Model are you referring to?

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.

Trance,IMO I think what was just said sums it up,if you want to "shake the walls" then JL is the choice hands down.If looking for seemless 2 channel, 1 Rel will do it.There is no need to run a pair,waste of money..B series or an older/larger model(and thats coming from a person who has Dynaudios and tried both!).
