Bit of a bump here, been thinking much the same as @twofingers for some time, am now looking at a active one way cab build and pointers to existing solutions would be cool.

GK makes very good powered cabs MBP series. Been thinking of running them off a tech 21 bass fly rig.This thread is for posting your knowledge and experience (or even just a web link) regarding powered (active) bass cabs. Not PA cabs you have used with great success. I'm curious about dedicated bass guitar cabs.
Have you used one?
Who makes them?
Are they any good?
Your thoughts/impressions?

kinda. They require a super hoofy signal which the combos deliver. There is also their plex preamp pedal set to do same.From what I gather, those cabs only work with GK combos as an extension. Read up on them. That may have changed. You can't just run any signal you want to them, I believe. They have a proprietary circuit that only accepts input from their own amps.
I doubt it would come close to powering up an MBP.GK makes very good powered cabs MBP series. Been thinking of running them off a tech 21 bass fly rig.

If you really really wanted to do it there would be someone who could say what the signal level needs to be to get them working. I did read a spec on here once but all I remember was 'dang they aren't messing around making it it hard for anyone to use other gear with their powered cabs'.
Sansamp PBDDI + GKMBP115 = some pretty nice noise.
So, due to some band work that has started to come my way (amp-less stage and IEM set up) and that I've kinda been in bass amp rejigging mode lately, I've discovered these Sansamp thingies. Then came the notions that this little pedal possibly could also be used to drive a stage amp set up....
After reading as much as I could on the "preamp driving a powered bass cab" topic, I happened upon a deal on a practically brand new GK MBP115 today, with the hope that my Tech21 programmable BDDI would work with it. (All kinds of helpful info here and in other places...so thanks all! There was, in particular, one post from someone who said this combo of boxes worked....so.... ).
I use a TRS 1/4" to xlr adapter from the driver's "parallel out" to run to the MPB xlr input. Selecting the +10 db boost on that output in the driver sure helps too.
The result----seems to work just fine. Should it/could it be louder? I un-scientifically compared the parallel out to MBP volume to the driver's DI out running straight into a 200W power amp driving a passive 15" cab....had to really crank that power amp's level to almost max to be able to hear the passive cab over the MPB.
Now I know there are likely other variables (cab efficiency, etc) but a seat of the pants meter says this is gonna work just fine....as a stage bass rig for most of my "non-PA supported" outings.
The only downfall is the lack of a "master volume" on the powered cab....but c'mon....can't have everything...right?
I bet the Le Bass and Q/Strip combo sounds wicked. Two very highly regarded little boxes!!
