In case someone doesn't know, Q-Logic boxes absolutely suck! Says it's designed for a 10", but it's really for an 11"...where the hell do you find that??? Now, plastic Q-ring? Impossible to get the box air tight! They give you 10 feet of tape to seal it? Even that doesn't help! Particle board??? OHHHH NOOOOOO! Falls apart when the screws go in! Finally got it in without the ring, but still leaks air!
