You need to decide how & where you're going to use it.......Then pick the best box for that.
Someone should make a decision flow chart.
Want loud as possible? OK, but do you care how heavy it is? If not, get a Panasonic A2. If yes, get a JVC M70 or M90.
Want a looker with tons of chrome and LED's?
Want a shelf box that oozes quality?
