I tried that combo for reinforcing my Porchboard Bass. The results were not good for my purposes, or really, any I can think of. The sound was "hollow", as it didn't have the EQ applied to the B1s from the L1 Power stand.
I've tried finding a good, small, simple Crossover that could be used in front of the B1s. Found a couple of raw, circuit board types that had to be hardwired, but never found anything to my liking. So I've given up on the idea.
I've gone with scaling the gig gear to the instruments involved. Full band, two or three Model IIs with B1s. Duos, and open mic gigs, two compacts and a T1, but no mic'ing the kick drum. This forced me to modify the kick, and tune my drums a little better. It's working out.
I see you use a single Model 1 typically. How often do you do DJ gigs with your Compact(s)?
Makes sense actually. I've only started using my Compact for smaller receptions recently and have been absolutely blown away by it, although it certainly has limitations. Here are some pictures from the first time I used the Compact exclusively, even though I had an L1 M1 in the car with a pair of B1s.
