JL Audio F113 or F112 For Dynaudio Confidence 5

My room size is 20x15 and I've owned 2 REL subs, the Storm II and then I switched to a REL Stentor III. I heard about JL audio from car stereo days and was curious.Long story short I sold the Stentor III and changed to dual JL F113's and have never looked back!Sad part about it was after arguing with Sumiko back and forth they finally replaced the internal amp on the Stentor which is a known problem.They tried to tell me it was my Levinson amp causing the problem although it had functioned without a hiccup for 3 years prior to that. REL's are musical but lack the output to really bring the feeling home especially with HT. The REL amps were never designed for high output HT or music.Two REL's would be great but outrageously expensive.My Fathoms are the most dynamic and musical sub I've had in my system and I've gone through a few to get where I'm at presently.If I could compare the two in closing it would be the REL will reinforce that last octave of bass missing with most speakers. The JL will also do that but add a tad bit more realisim due to it having the ARC function that helps smooth the bass out in the listening position.

JL subs have a wonderful on board room correction system that helps you dial the sub in for seamless perfect sound. Also you can run the output of a JL112 to another JL112 and let the same set up program dial in both woofers.

I own the 112. I have one in my theater and one in my music system. Both are excellent for music. One night I moved the 112 (UUgh heavy) into the music room and dialed both in and tried two subs. Two were definitely better than one.

For years I was an anti-sub guy. Now I won't have a system without one. I hope this helps.

Wow, thanks for the education, this message board has helped me understand many things I didn't know. I notice the Rel's sell instantly when they come up on audiogon, JL audio sell very well also, their seems to be more JL subs available on the used market this makes it easier to find a good deal. I am guessing more JL subs were sold in the market resulting in more sale availability on the used market. I will start with one sub and then move on to two. Thanks for all the help.

I just read through this entire thread. Very helpful information. I am considering adding a second Earthquake MKV-12 to run in stereo, or sell it and buy one JL 113. Based on what I read above I am going for the second Earthquake - and can always change to JL later.

Any opinions on this move would be much appreciated.

My speakers are Dynaudio C1 with Pass X250 amp.
