In general I don’t buy cabs I can’t lift and or transport on my own regardless of speaker size. Even at age 72, and certainly not a towering hulk by any stretch of the imagination, I can still manage to lift and carry an 80 lbs amp rack. Big stinking woo! The question is why would I want or need to?I feel like we all have different thresholds for what we consider to be a light cab, so it makes me curious: what's your personal weight limit for a 2x12?
The other considerations are , I’m 72 and I know I’m not going to be able to do that forever. The other is while the muscular skeletal part may be fine with it, my sense of balance is not what it used to be. So I have to be very careful there is nothing to trip over where I’m hauling it.
