JL Audio F113 or F112 For Dynaudio Confidence 5

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!).

Can Rel still be serviced in the USA if it breaks?

Trance, I have two F113's with Tyler Acoustic D3's which integrated very easily in my big room. One sub was still good but adding the second was the ticket. Two F112's dialed in for your room size would be all you need. Both the F113 and F112 are extremely musical and fast. Start and stop on a dime. Once they are dialed into your liking you won't even know they are there. I would do two F112's before one F113 if that is even an option. Also, hearing or feeling a difference between these two subs is going to really depend on what is going on in the room. You are moving air inside that cube so one is going to sound a little different than the other. At 80hz you may not be able to tell but anything below 40hz you more than likely will feel the difference. You can control the response of the room easier with two subs as well and it won't affect the neighbors anymore than with one unless you want to.

Trance, Forgot to mention that the JL's like any other good sub can shake your walls if want them to. For movies it is fun but the JL's are built more for music. They are extremely tight when you get them right and create an uncanny black background.

As mentioned earlier, I had a 112 then went with two 113's. To me two are far more superior than one. I can't say the the 112 sounded worse than the 113, on it's own ( single sub drive) However, I have played the 113 solo and and a pair several times. There is NO comparison period. I agree that the JL's are superb with music. I can't comment with video and shaking walls doesn't do anything for me either. Get two of whatever and let it be done with ....... MHO
