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).

Re the Dynaudio 18s

I want to make sure we ARE talking about the same item. The 18s is very compact in fact and is $1799 at Sweetwater:

The dual opposed design results in zero vibration being transmitted through the floor.

If a sub is getting its sound into the room then sound is also getting into the floor. Unless you have no floor.

@mijostyn Anthem finally got back to me on this. It seems that adjustments can be made with the ML Perfect Bass Kit by enabling the Professional Mode. I'm not sure if I'll know what I'm doing once in the program, but at least it's a start. Here is their response:

There are many YouTube videos that exist to aid you with the ARC process, however these tend to be more product specific. You are welcome to share your ARC file so that we may take a look and make the adjustments you are looking for. Be advised flattening the response curve does usually result in "lower" bass, but there are ways to adjust this such as using the Room Gain and Deep Bass Boost settings in ARC Genesis. 

@wolf_garcia maybe I could "Float" the subs?

There you go. Do exactly what I said with the deep bass boost. You have to dive in. Just keep the volume low and you can not hurt anything. There is also nothing you can't undo.

Bass goes everywhere...it simply cannot be directional by nature, and note that many subs (including a couple of mine) have down facing drivers...you could suspend subs from the ceiling (ha) but if bass gets to your ears, it's getting everywhere else. I have 2 RELs in my main rig and after reading something about WIlson suggesting the Loki's placement as having its voice coil in line with the bass drivers in the mains (makes sense), I adjusted a sub (front firing) to be in line with that suggestion. The other sub is off to the right...a standing wave defeater. This works and I suggest this setup to anybody with a listening space and gear EXACTLY like mine.
