Looking for the "better sub"


I have Magnepan 1.6/QRs and would like a sub sometime soon to fill in the low end.
Subs suggested to me have been as follows...

Vandersteen 2wQ....problem with this sub for me is most agree I need two from the start for my 25X15 room.
JL Fathom 113....I would have ordered one, but no high level inputs turns a great sub into a home theater product in my eyes. They blew it.
Martin Logan Depth....still a frontrunner. Quick and musical. And one works well enough to get started.
REL....Still looking into these.

So I guess I'm looking at a budget of about 2K...a bit more or less. Anything else I should be looking into beyond the above? Please comment if you've heard the models above, which (except for the Fathom) are well known for working nicely with Magnepan panels.

Thanks!

I am not sure that something linear is a good thing with panels. You may struggle with different SPL levels ....a match here but then a mis-match there. A small sub might be the optimal fit- something with limited excursion/small woofer and which compresses at modest volumes - like the REL's for example. They would probably be the best fit.
Used Alon Thunderbolt.

Shadorne..."I am not sure that something linear is a good thing with panels".....you kidding right?

BTW...I have panels, and a pair of very large subwoofers. I also have a pair of smaller subwoofers...I'll place my bet on larger any day.

I will throw in a vote for a pre-owned Martin Logan Descent, the reason I say pre-owned, the new I Descent is not as good as the previous Descent model, leaps and bounds better than the Depth that you are considering as well.

Really?....I don't understand how you have come to that conclusion about subwoofers?>>>

I tried high level inputs vs. low level on three subs and there is no doubt at all that high level is superior for two channel audio. This is not possible with the Fathom, no matter how good of a sub it is.
