20 hz to 350 hz. Has a pair of MB couplers? That is a lot of room to blend a bass bin.. Use to be hard to find one that would go that high.

Those numbers (20-350) were used to blend Soundlab or Quads.
speakers. Usually a 12", can go as high as 800 hz or so before they really start ringing. Looks like 6.5 or something? Probably go even higher.

Looks like it has separate tuning ports for them also... Sure a honker on top.. Facing forward, though, I don’t understand. Back, down, side or up, but not forward... I guess you could get it to work better, closer to a wall?

Millercarbon,
What is a DBA? Digital equalization? I do use the equalizer in iTunes with good results. I would not have a subwoofer without DSP now that I have gotten used to my Velodyne DD10 (now broken), it really evens out the bass in the room. I ran my main speakers through the 80hz filter and let the 10" servo controlled, acoustic suspension, 1250W handle the low frequencies. It seems as though going up to 350hz would allow localization of the sub, causing soundstage balance issues (unless I got two subs, but two 18" subs with 5,000W of power just seems out of bounds for an 11x16' room, lol. 

DBA is distributed bass array. Means four or more subs in essence. The idea is that four subs can perform better for a variety of reason than fewer can, and you don’t have to spend as much on higher end ones, can spend less on four than two, and achieve better results

I bet it can reproduce earthquakes

Well with four paradigm sub2s on 230v each, ill find out.
