Yes-I used mine last night (and it was with my free Genz gig bag I received as part of the offer when I bought it-as well as a $25 gift card).
It handles the lows, but the 10" speaker can only produce so much. I also went through the PA using post eq DI and that produced a super-deep tone (with the bass knob just at 1pm and the LF NOT activated). In fact, it was too deep for our speakers...when I went pre-eq it handled my bass better in the PA.
So...yes, it can handle the low B.
