Which Sub. Rel B-1 or Fathom F-113

My Ref 3 also has 2 sets (4 in all)....two balanced and two SE, so it will be no problem

With two unequal loads running in parallel it would have put great strain on my Ref 3. This way it is prettty effortless. It was done also at the advice of the people from ARC

Ozzy...I run my X-2 series ll's full range and use my two Gotham's to fill in the bottom. Depending on the input impedance of your amps you might need a tube buffer or something similar as you will be running two loads in parallel. Here is how I solved the problem in my system

Once you own the Fathom you will lust for the Gotham. IMO the JL Audio subs are the ones by which all others are judged. You won't be as happy with the Rel

I run a pair of Gothams in my system.

Not true, the Rel subs are more musical and also faster. They integrate better with high end speakers. If you are going 2 - channel get the Rel. Nothing loads a room better than a Rel! I dont think you will need the brute force of the JL, which is better for high SPL. BTW, there is absolutely no port noise.

You have to try them both. The Rel will win because they are fast enough to keep up with you Martin Logan's and disappear into the background

I hate to say it but you are delusional/ BTW, I would like to think that my Wilson X-2's are high end speakers. Prior to my pair of Gotham subs I was using a Wilson XS which had a pair of 18" drivers. After I heard the Gotham I immediately sold the XS as IMO it couldn't compete anywhere near as close to the Gotham.

I agree that the pending 212 will be great as well. When it comes to JL Audio subs there hasn't been one critic that feels there is a better sub made.

Here is an interesting read from Jeff Fritz

I have a very good friend who has the TOL Rel in his system and each time he listens to my setup he just shakes his head and smiles.
As far as cables I have ~$50K of cabling in my system so I am very familiar with cables and you are preaching to the choir. For the size of your room the F112 either singly or as a pair would work just fine. I agree with the previous poster as to the speed of the JL Audio drivers.
A final caveat is perhaps your room isn't set up correctly or your subs weren't positioned properly.
I also agree that it is a matter of preference. IMO the REL used to be the leader of the pack but they now have some catching up to do

Well I suppose that one can then have a look at the new Thor's Hammer by Wilson Audio
