Subwoofer Advice


I am running a pair of Martin Logan ESL 13A speakers (24-23,000 Hz). I would have thought with two 10" woofers there would be more bas (the base level dial on the rear of the speakers doesn’t seem to cut it either).

In the past I had a pair of ML Spires (29-23,000 Hz) with only one 10" woofer that had so much base, I sold my pair of ForceField 30s. Not the case with the 13A’s.

I don’t have a lot of room, maybe 16" or so square and I was wondering about a pair of SVS Micros. Do you think they would complement the 13As or do I need something bigger?

Martin Logan has come out with a few new subs lately; do you think I should keep in the ML family?

Hoping to come in under $2K, so used is fine. Thanks all!

I should also mention I’m limited on space so placement would likely have to be on the inside or the outside of the main speakers (same back wall).

."@russ69 are you saying move on from the MLs and hook up with some Infinity RS1B towers or Tektons?"

No, the ML13A are fine speakers. My brother ran ML Requests for a long time. A stereo pair of towers does amazing things. You will get entirely new and deeper sound stage.

EDIT: I prefer stereo subs on the inside of your main loudspeakers.

@navyachts OK, I reviewed your pictures. Does the Anthem program have EQ capability? Can you increase certain frequencies manually? I assume you measure the speakers with a microphone? You should put sound absorption directly behind the speakers. It will improve your imaging and dampen sibilance. 

I also use ESLs and have been since 1978 along with subwoofers. If we can advance the low end 10 dB at 20 Hz keep it flat to 60 Hz then curve it down to zero dB at 100 Hz you should be fine without added subwoofers as long as the drivers and amps can handle the volumes you like to listen at. If not then we have to fill in with subwoofers from 80 Hz down. There are not many commercial subwoofers that are clean enough for your system. Martin logan has its balanced force subs, but you will need two subs. Do not even think about one. In your situation I think the best subs would be the KEF KC 92. They are also balanced force and you can get them in white which would fit your decor. They are quite small. I would put one right next to each ML, either side will do. I am hoping you will not need them. 

Bricasti Design just loaned me an M1 DAC to play with. Nice unit! I live about 30 minutes from the factory in Shirley, Mass.  

I am a happy Rythmic 15 in sealed sub user. Contact them and they will give you guidance on the best sub(s) for your application. They are very reasonably priced given their performance and flexibility.

@mijostyn +1 on the M1 DAC!

I am not sure if I can increase certain frequencies manually, nor am I sure about the program having EQ capabilities. Even if these features were available to me, I’m not sure if I could figure out how to do it. This kinda sounds a little to techie for me.

If we can advance the low end 10 dB at 20 Hz keep it flat to 60 Hz then curve it down to zero dB at 100 Hz you should be fine without added subwoofers as long as the drivers and amps can handle the volumes you like to listen at.

 

I have 11As and use 2 REL S/812s more to improve the soundstage than for deeper bass. Sounds great. Also I have gotten better sound by moving them 30" from the wall behind them. Room treatment has helped enormously, especially the Stillpoints Aperture 2 panels. Hope you get there. Joe
