Any love for powered subs as part of your rig?

I was checking this thing out, looks like it would be a great part of a bass rig from the specs...Probably have to put it off to the side tho.

It's a 1000 watt amp with an 18, the crossover chops it at 140, and it has a 3 band eq. I think I would rather have a crossover that could be dialed in but hey.

I was thinking this guy combined with a Markbass traveler, or a Phil Jones Suitcase would be all you would need, or would it be too boomy? I like the idea of part of the bass amp showing up with the PA stuff tho, and breezing into gigs with nothing but a 2 x 8 cabinet and a gig bag.

Not that expensive either.

I just got an F2 (something like that), but mines downfired, OBC2000 or something? 12" powered with a 430 watt Bash amp(200 watts rms). I haven't tried it yet, as I have a new years resolution that i cant play with my new toy until I clean my bedroom (I feel like I'm 12) here is a few square feet of my room. Wife is out of town, and the whole room looks like this....
Yea, from now on, one project at a time....
