Subwoofers - Final Thoughts with Martin Logan ESL 13A

navyachts,

"@ricred1 sorry, I missed the point, are you in agreement with @rauliruegas ?" I submit audio is personal and there are no absolutes. I personally don't like REL subwoofers that use a "passive radiator", because my listening room is upstairs and I could hear the radiator. My point was REL does have "true" sealed subwoofers(No.31 and 32). In my system, I prefer sealed REL subwoofers and I use dual REL No. 32 subwoofers. In my room/system, it isn't just about bass, but how adding the No. 32s have improved everything across the audio spectrum and the soundstage. I prefer the 32s to every previously owned subwoofer...dual JL Audio F110, dual JL Audio F112 v2, HSU, Martin Logan Depth i, and SVS 16 Ultras. I prefer my system with subwoofers, some don't.

Dear @navyachts  :  The SVS App will be tell you all about the placement of 2 subs and everything around:

SVS App Specs:

• The most powerful and flexible Bluetooth controlled subwoofer DSP app, works with both iOS and Android operating systems.
• Easiest and most convenient way to adjust crossover frequencies, parametric EQ, polarity, room gain and all other bass management functions.
• Three convenient custom presets allow for perfect tuning in any room or system, from your favorite seat.

• Single tap adjustment for controlling variable port tuning with standard, extended and sealed modes.
• Unique bidirectional feedback shows adjustments in real time on both app and subwoofer interface.
• Easy-to-follow tutorial provides clear guidance for all functions

You need a High-Pass filter for your main ML speakers, this is critical.

Yes the 4000 can function for your room/system

@ricred1 at almost $13K a pop you better prefer them to the measly priced SVS 16 Ultras :-)

@rauliruegas thank you!

It's what I prefer, but it certainly doesn't mean they're for everyone. In my opinion it has nothing to do with price, but what I value. Everything impacts a system and in my particular case, purchasing REL No. 32 subwoofers and a Antipodes Oladra music server has been two of the best decisions I've made for my system. I submit SVS and RELs impact systems differently. 

I have been following this thread to read how different opinions can be.

Stat users are either in the ML camp or "other"- Soundlab, vintage Quad or whatever. 

Your 13A's to my ears can sound very impressive with basic placement according to room allowance.- living space or dedicated.

If it's NOT dedicated, then you accept what you have and enjoy.

That's including bass response.  As audphile1 mentioned- those things need to be pushed out into the room. If space allowed doing 1/3 of room or Cardas might be ear pleasing.

Sub or subs will always  make the experience more enjoyable.

It doesn't need to be so technical as implied here.

Just my thoughts. I use ML's previous generation, bottom of the "premier" line Theos-passive woofers. They are supported by 2 ancient REL's but alone deliver listeanable performance thanks to placement and SOURCES.

I can just dream for know about  some giant Soundlabs and a swarm of REL No 32's.
