For ease of transport and being able to switch driver cabs at will - next time I'd get the B-600 head and use it with all my other Acoustic cabs mixed/matched as desired.
The B-450 is super good and punchy - but I think now I would rather have the separate head.
I've got every Acoustic driver & cab except the Neos and they all sound great and move a lot of air - but it depends where you're playing too.

Don't try it in the bathroom - the sustain will drive you nuts! Don't ask how I know.
