Review: Great Subs! - I bought 2 of these before the TARRIFFS. Now they are$500 more everywhere.... these are Great subs for djs.
Review: The real deal. - This is an excellent unit for my mobile wedding / pub gigs. There are products that go 'lower' or go 'louder' but this thing delivers excellent punchy bass that fills the room day-in and day-out at a great price. Combine it with a screw-in type crank-handle speaker pole and you have a solid base for even the biggest tops. Pairs great with my 68lb SRX812's. The included built-in casters are quiet and strong. Don't forget to order the factory cover to keep your investment safe!
