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!

@ricred1 I feel the need to sincerely apologize to you yet again - and to thank you for answering my question.

 

My apologies

 

I have never understood the preoccupation with bass. For half a century we didn’t even have subs. When you listen to a live band do you experience the bass is missing? I just don’t get it. I have ML’s, and I have more bass than I need. This without a sub. End rant. 

@coltrane1 Sorry then about my post, you're probably right!

If you don't mind me asking, what model MLs do you have? 

Your system isn't virtual here.

One option that doesn’t get much airplay on Audiogon is Perlisten. The company does advertise in the glossies, but rarely offers its products for review, so it’s not surprising that it flies under most audiophiles’ radar. However, when Perlistens are evaluated by a credible reviewer, the raves are almost embarrasing. See the last link below.

The reason I recommend them for use with an electrostatic is their reputation for speed, transient response, detail, and transparency. Having spent decades sub-rolling my vintage Quad ESLs, I’m no stranger to how tricky it can be to extend the low end of an electrostat.

So it strikes me that even a pair of Perlisten’s entry-level R10S (physically smaller than you’d think and reasonably priced at $2K per) might be a great match for a ML stat. 15" cube, 45lbs, sub-20Hz extension. Downside: no DSP / app.
