I bought 2 of these before the TARRIFFS. Now they are$500 more everywhere.... these are Great subs for djs.

### ⭐⭐⭐⭐⭐ Powerful portable Great quality
*by J***A on January 31, 2026*

Love this Sub. Great sound and response. Powerful

### ⭐⭐⭐⭐⭐ The real deal.
*by D***T on December 3, 2021*

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!
