I added the Acoustic B-115 to my Acoustic B-450 (210) combo to fill in the lows, and it works very well. Acoustic's B-115 has all the oomph you'll need, but unfortunately, as posted above (^) the B-100 is a little light in the ability to push much sound. I wouldn't mind having the B-100 for practice - but I never get any of those intimate and small venue places to play that might be better able to appreciate it. I leave those things to people who need to hear a professional, paid combo since I'm only playing for fun.
But I've got 600 Watts of power at 2 Ohms so I can drive the 15-incher with watts to spare so I also added another cab - the Acoustic B-410. We play rural outdoor BBQs and lawn parties where the open air sound dispersion is very high, yet I can fill the area with gob of bass.
There are other, greater powered big names and more professional rigs out there and I know and appreciate them all - but I just went this way (with Acoustic Gen-II stuff) and don't regret it.
More Watts are always good. Excessive Wattage is better!
