Ricci... I have to ask, hows that XXX18 sound?

Deep...like the ocean . It's crazy when you feel the floor ripple and you get shoved by the pressure wave but it isn't accompanied by easily discernible sound because it's so low. :T Like when something heavy is dropped or set down and you feel the ground shake. It can actually pull off a pretty convincing reproduction of stuff like that. It also sounds very nice with music as well.
It's 25ft net, tuned to 11hz with a 10" based power port design. The power is from a bridged Crown CE4000. I use the 8hz DC filter in the amp for my highpass:whistling:. The full build log is here at the Shack.

I have a question for the inputs for the AVR to the EP2500. What do I use! Do I wire up a TS/TSR 1/4" plug to a MONO-RCA and hook that up to the subwoofer pre-amp out on the Onkyo 805?

That should work, or you can even wire up an XLR to RCA cable. You can buy cables like this at various places also. I'm not sure about mounting the amp in the box. I don't see why it wouldn't work but it seems like a lot of work with adding extra fans and all.

Make sure to get some pics during the build and keep us updated. BTW you are going to need a SSF to protect the driver from over excursion below tune.

Reckhorn B1 from Creative Sound Solutions. Unlike the E.D. eQ2, it's guaranteed to work with a pro amp.

No, that's the F1. You need the B1.
