The sound reproduction is great, but need more volume. Also no remote to control the volume, but a good buy

We wanted a portable sound system for BBQ, parks, and beach activities. Found this box and for the price I am pleased. Robust sound. Bluetooth connects Asap. So far so good. Throughout the years I've purchased gear from Sam Ash always been a pleasant experience. I bought my sons Yamaha dgx-650 at the Queens location near my old neighborhood. This is the first time ordering for delivery. It came in perfect condition and fast. very pleased with this purchase.



Great job


It was everything I thought it would be
