Thanks Jazzy! Totally agree, their 12" ones are probably my preference too. I've seen your BF rig in another post; looks awesome.
They're great for guitar as well! Since they're FRFR, you can run anything through them, just depends what preamp/modeler/amp you use.
The 10" line is great too, just more specific to bass.
And the low weight... wow, what a difference between them and pretty much any other cabs I've played through; it's terrific. Even just setting up that photo with anything other than BF would have probably sent me straight to the chiropractor (or the hospital)
