1) a sharp drop off below 20 hz. That is to prevent unloading the drivers and would be your highest priority to address. That's why I mentioned the filter earlier.
2) a little hump in the low 20's - you could live without that
3) a natural response shape that is relatively flat - more flat than what you'd get with a sealed sub normally. Going to another amp might give you a more humped response, but that is something room eq (e.g.Audyssey) could address, or you could see if you can live with it.
A PB-2000 might give comparable output from 18-30 hz (probably a little less) but would be nowhere close for midbass.
I spent quite a bit of time reading about SVS subs (although I am still pretty much ignorant on the graphs and hz.
Remembering how Epik sounded, it was perfect in so many ways - all bass levels were filing the room without sounding like a cheap boombox just trying to pump out bass. So, I've decided to test out PB-2000.
I got PB-2000 from SVS, it was their outlet model, which SVS claims is as good as a new sub.
Long story short, either I'm doing something wrong or what a disappointment... I can barely feel or hear any bass, and if I crank up the volume on the sub, it sounds like a cheap ears-hitting boombox, unable to fill the much smaller room (Epik was filling open floor ~ 1,100 sq. ft.).
Mid-bass on PB-2000... what mid-bass?
I'm now considering returning the SVS sub, and try to fix the Epik.
Is it just me or Epik sub was just so much better?

So right now I am running 6- 15" Epik drivers off of the amp. The adjust-ability on the Behringer is very nice. If you decide to keep the Epik and go external you wouldnt need the NX6000D for your setup since you are only powering 2 subs. You can go with something like a Behringer NX3000 which go for about $300.
I looked at the internal amps and they seem like a simple easy bolt in fix. However I wanted something that can power more which is why I went external. It was very simple to convert to external. I actually left the plate amps in the Empires, I removed 1 of the XLR connectors and put a Speakon connector in its place. It actually looks like it belongs there. Its nice now since I just have to run speaker wire to the sub and not sub cables. It makes it easier to move stuff around IMO for when need be.
As far as what to offer for the sub. To be honest, the last 2 Empires I bought, were very cheap. I am in CT, I drove to NY to pick up one with a bad amp and paid $200 for it. The other I got from a member on this site from California. He wanted $100 for it with a blown amp and for me to cover shipping. It came out to about $200 total shipped to get it from Cali to CT. I need 1 more Empire to make a total of 8 drivers and I will eventually make custom enclosures and totally remove them from the opposed firing boxes they are in now.
Thanks a lot! I think I might attempt to fix the sub. I've decided to give SVS PB-2000 a try (please see my other reply above), and was so disappointed in the way it sounds and fills the room, or doesn't fill the room I should say.
For the same price point (both $800) SVS PB-2000 doesn't deliver much comparing to Epik.
I will try to move it around the room before I decide to return it, but Epik might be just a much better sub worth keeping?
