Subwoofers - Final Thoughts with Martin Logan ESL 13A

I’ve narrowed this down to 3 choices (I think) and was looking to see if anyone has had some experience with pairing these subs with ML ESLs? I can’t try and return because they are mostly secondhand purchases, so hoping to get it right the first time!

Force Cancelling subs have been highly recommended, so:

KEF KC92 (or KF92 older model) 2, 3 or possible 4 of these:

Martin Logan BalancedForced 210 - Maybe the best as they match up nicely, but I could probably only do one of these as they are HUGE. I have only one spot I could put one as far as the manual's recommendation goes. Martin Logan says these will cover 3000 sq. ft. My room is only 500 sq. ft. Two maybe overkill, but some say, "2 subs or no subs" Maybe I could put another addition on the house :-(

Lastly, The Swarm Subwoofer System - not sure how well this would work with my ESLs.

Any advice would greatly be appreciated (as usual).

Thanks, and all the best of the season to you all!

You can feed the sub from your preamp RCA out if you’re using XLR outs to drive the amp

@audphile1 I see the Coda has 2 RCA outs (L/R) and the M1 only has 1 (L/R) out. Is it better to have the two outs if you're running two subwoofers?

Hmm, maybe I should I keep the Coda? 

The RELs leads hook up to the power amps speaker's output connections, but I think I have been talked out of RELs.

I wouldn’t sell any components if I were you. You may regret it.
Try a sub first from the dealer that has a good return policy (Music Direct, Upscale, Crutchfield). You can use the Coda preamp to drive the sub(s) if you have 2 RCA outs. See how it works with your preamp. 
Also…your dealer stating the woofers in the ML speakers aren’t fast he’s full of 💩 

ML finally, after many years, were able to get the panel/woofer integration correct.

rauliruegas,

" Pleaso do it you a favor and stay away of REL that it’s not a true sealed subwoofer but with a passive radiator that almost function as a ported one." REL No. 31 and 32s are true sealed subwoofers.

@ricred1 sorry, I missed the point, are you in agreement with @rauliruegas ?

I'm starting to get cold feet about this whole subwoofer thing, There's so much conflicting information. Maybe tone controls are the answer...LOL!
