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!

FYI, my subs are set at 70hz.  Perhaps start at one end and move to the other to find what suits your ears best.

@audphile1 OK, I move my listening chair closer in and moved the speakers further out from the wall, then toed them in a bit more than the ML recommends. I also ran the Genisis Arc program (in auto) and as long as I play well recorded, bass heavy music, (like one of @jasonbourne52 favorites, Slow Jam by Euge Groove), it sounds pretty good and goes pretty deep. One thing I did notice, when I turn the .arc3 file off (so less bass) I hear more detail in the mids and the highs than when the heavier bass file is turned on.

I’d still like to try a sub. I have my Coda pre-amp up for sale so if & when it sells, I may use the funds to pick up a sub (or two).

@docknow I see a couple of 210s came up here on Audiogon, I’m trying to scrape of the funds for one or two. Christmas time is a tuff time to do so.

Thanks to all for your help & advice!
