Is JL best sub for the money?


Looking for a sub to complete my fathers system, Vandersteen Quatro Signature speakers, Audio Research Ref 3 pre, Aesthetix Atlas amp. System is in a 13x22 room with treatment but no bass traps. The JL 113 is what has my fathers interest and used it comes at a good price, so for around $2500 is there other models I need to check out new or used? I do admit I like the idea of a calibration mic the JL offers so that or a EQ with test disc would be huge bonus.............thanks for all ideas.
PS While the Vandersteens dig low with his Organ playing and Classical music collection that bottom end is something we will only get with a sub, I have hooked up a Def Tech 15in sub to show him benefit of air and slam so just need something more musical and tunable. again thanks

Good to see you posting Chadnliz, I agree with Shadorne about hard to beat at any price.

I recently installed JL Audio subs in my system. This is the first time I've successfully integrated a sub for music playback.

After calibrating, the Fathoms disappear into the image of my main speakers. No hint of their presence except for the very deep bass that was not there before.
Albert-did you play with any subs when you had your soundlabs;just wondering as I have M2's.
