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!

@rauliruegas I get it. But…I’m enjoying the music with my system and I do not hear IMD. Neither do I need to obsess over it because…
According to Wilson Audio…

The tweeter is isolated internally from the midrange and woofer drivers with the latter two transducers sharing the same internal volume. Wilson Audio notes that in this configuration any potential for intermodulation distortion is minimized by prudent driver selection and precise porting of the enclosure. 

This sounds like truth as I cannot detect any distortion. The drivers cross over seamlessly. 
 

I’m very thorough when it comes to my system but I think we’re attempting to shoot down a fly with a bazooka here…

By the way I looked at your system page and I’m very impressed! Gorgeous system and some collection of cartridges you got there…enjoy!

The one thing I like about the Rel is that you can potentially hook it up and use it as support when watching movies. Is this an option with the SVS 16? Does this mean finding s radio shack to rig some connection?

I should add that I just have a basic tube amp, not a receiver with all sorts of "outs" so I essentially be hooking the sub up to a soundbar for tv use.

m-db,

My subwoofers were set-up by my dealer using REW, listening, and the No. 32 parametric equalizer. They are on the outside of my speakers.

"you are the only staunch sub user I can recall who prefers a -6dB sub-bass speaker to the -3dB subwoofers you’ve owned." Subwoofers aren't just about bass and that's why I prefer the No. 32s. It’s what I prefer based on actually owning several subwoofers. As I always say, no absolutes in audio, only preferences. I don’t understand why people care what people spend their money on. It’s simple, if you don’t like REL subwoofers, don’t purchase them.
