Guys - I have a Crate TX50DB which has a single woofer and a 7 amp hour lead acid battery. This one appears to be about the same size/shape as my Crate. The Crate is a great amp but is heavy at 32 pounds...looks like the weight on this one is only 16 lbs. But the lead acid battery adds about 5 pounds to the mix which is not a factor here...this one is a bit more expensive than my Crate too...looks like it is getting some good reviews.
