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!

Stereophile Review, I’m gonna read it now

A quick read revealed t was not a finished product when reviewed, an excerpt:

"Finally, I want to make it perfectly clear that, as of now, I do not recommend this speaker. If and when the design stabilizes, and I have a chance to evaluate a true production sample, then a final assessment can be rationally made. I consider it insane to spend any money on what has to be regarded, for now, as an evolving prototype."

I am extremely happy with my one ML BF 210 and my two CLXs.  Integration is important and ML gets you there easier with the custom crossovers you can download to the 210 and the PBK kit.  I previously had Kinergetics and Entecs.  The 210 is far superior.

Wow, not your typical Stereophile review - and by Dick Olsher no less, practically Bob Carver's Vacuum Tube Audio's personal press rep during the Cherry VTA 180 release. 

I still can't get my head around how someone could modify one of his solid state amplifiers within a two week stay in a hotel room with the parts on hand, and win the challenge!
