Would Martin Logan Spires benefit from subwoofer?

While the Spires really improved on the Panel/Woofer integration, adding a sub will help. IMO I like Servo Based Subs with stats. But the biggest thing that will help out with the Sub and integration is the DSpeaker Anti-Mode 8033 Sub EQ system. I messed around with a Velodyne SMS-1 (same thing that is in the Velodyne DD series) and measures, tweaked, auto measures, manual measured, tweak, changed settings...FOREVER and really could not get my sub to sound as good as I thought it could (I have my room EXTENSIVELY treated for acoustics). I finally bought the DSpeaker and within 15 minutes of unpacking hooking up and running the calibration, I had the BEST SUB response EVER in my room. Selling the SMS-1 was a no-brainer.

Thanks for two great replies, folks! I'll be experimenting shortly and will post results.

Well folks, I've come down to these possibilities:

One Martin Logan Descent
Two Martin Logan Depths
One JL Audio F112 or F113

Any ideas, preferences?

I would normally say ML Descent because it is easily setup to go with your MLs most likely...But JL Audio is one serious sub.

In the end, with your room, if you can do 2 subs, many people say [properly set up] it is far smoother. And i can imagine that is absolutely right. So i would say 2 ML Depths.

I just bought a JL Audio F113 sub to go with my Martin Logan Spires. Should I still use the powered woofers in my MLs, or should I just unplug them and let the JL do all the 80hz and below work? Or, any other ideas???
