“Great quality and customer service! Brian and Scott were spot on for my needs and beat delivery schedule for install. They reached out to the installation contractors and helped coach them through the install. And the best part, it sounds great!”

I own Mermet Springs, Inc which is a scuba diving facility with an 8.5 acre spring fed quarry in Southern Illinois. Brian and his team have not only helped us set up our underwater safety recall and sound system but has been there for us since day one. The speaker system they recommended includes just two of their speakers and allows us to recall our divers in the case of an approaching storm or if we need to do an emergency recall. The divers can hear us from anywhere in the quarry whether we are doing a recall or piping in a little Jimmy Buffet on their dive. Our system has been in place for nearly 20 years and has been seamless. We recently had to replace a transform but Brian was there and had us the parts in 2 days so we were back up and running before the next weekend. Their customer service is top shelf and I would absolutely recommend them!
