Hi Jeff, I use a QSC PLX 2402 and have been pretty satisfied so far, especially the weight. If you are willing to put up with about 10 pounds more and a few extra inches of length, however, the Crown K1 looks good. It's damping factor is around 3,000 vs. about 500 for the QSC. Plus it's color scheme matches the F1-X real well. Another thing to think about is regarding the cabinet, if you're not dead set on the DRBass yet... After years with a Henry the 8x8, now I'm using 12" speakers, specifically the Edens and the Bergantinos. They weigh 36-39 pounds each, and the Eden has 32Hz-14KHz and 103dB sensitivity. The Berg isn't as loud and doesn't have the bottom of the Eden, but adds a healthy dose of midrange which sounds good to my ears. 1 Eden and 1 Berg are sufficient for most smaller clubs or resonant rooms.

If I add another Eden, I have headroom for days.

I haven't felt the need to use all 4 yet. I'm running them full range in parallel mono, with the Eden(s) on 1 side and the Berg on the other. The light weight of the cabinets is great, and the fact that I can use only as many as I need is cool, too. Since this is turning into a photo esay on my rig, here's the front of the rack...

In the back, I used zip ties to stress-relieve a 3-way extension cord so I could keep the 4-space rack. The SF-2's wall wart is electrical taped to the X-cord to keep it from coming loose.

I'll eventually have to get a bigger rack when the Dragonfly gets here, but I'm putting it off as long as possible. Hope this gives you some more to think about... Charles
