The bottom radiator on one of my L1 Mod II systems is stuck in the power stand. I've repeatedly confirmed that the legs are fully extended yet the speaker won't come off. I've had to drag the speaker/stand out in the rain to load in my vehicle after a gig and I am not a happy camper at this moment. Another band member claims he has similar issues. As expensive as these things are, you'd think they've have better quality control.
