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!

That is why I suggest first finding out how low your speaker will actually perform.

OK, I still have to figure out how to do this first.

Velodyne - DDP-10+ - Digital Drive Plus 1250W Active Subwoofer

At $5,600 each, I think these are out of my reach at present but thank you for all you help and suggestions!

 

Running the main speaker’s full range and augmenting the lowest frequencies with the sub(s) is the best of both worlds.

subs used to boost bass will just completely break a good setup 

 

@navyachts definitely try a sub but I’m surprised you’re selling your Aurender. What do you have in mind for a source to replace the N200?

The M1 as network player. My Coda preamp is up for grabs as well. I'm using the M1 for that too. I like separates the most, but I want some decent subs as well, so it's a bit of a tradeoff.

Dear @ozzy  : I respect your opinions.

 

" Running the main speaker’s full range and augmenting the lowest frequencies with the sub(s) is the best of both worlds. "

 

Unfortunatelly it does not exist those " both worlds " and probably you don't understood what I posted about that very high ML crossover 300hz frequency that procuce a very high Intermodulation Distortion that contaminates all the ML quality response.

What that ML is doing is to develops " trash "allover the MLspeakers through that severe IMD.

When that " trash " is out of that ML woofers then the midrange, midbass and high frequency ranges now arepristine, with clear sound, nearer to the original signal and shiny all that system as never before:NO MATTERS WHAT.

 

@navyachts  deserves the best from his room/system.Btw, Velodyne is not the only subs that can help you inside your budget.Only look for a sealed subwoofer design.
