Amazing! Great Product! Review by Juan
I use this product for DJ applications. They are amazing for the size; very lightweight for such a good thumping sub. When you have multiple you can couple them and get an extra 3db boost or if you have more than two you can stack them and they are amazing that way as well. Stacking them makes them easier since they are ready for multiple stacking feature. The inputs in the back are great and easy to use. Overall this product is amazing. You can never have too many of these. (Posted on 4/1/2017)
