I really want to order up a pair of BB2's but I fear it's overkill.
Is anyone regularly and effectively using two of them currently? I suppose in reality one would only need them if they had no PA support. Am I off base here?
I use two all the time at our louder/larger gigs. It's not overkill for me at all but I have zero FOH support like you mention.
If you've always got good FOH support and your rig never has to carry the room then one BB2 would be a killer monitor.
I use a single BB2 for our smaller/quieter gigs all the time as well. Very portable and very capable, but it definitely doesn't have the same low end presence as a pair have. Running two of them makes me sound like I have great FOH support for when the band is really cranking along.
