Awesome product and great value.

I dropped in to the showroom on a whim to see if there was one of these in stock because I had foolishly assumed I could assign channels in my amp to a pair of passive subs. This was going to get me out of trouble. While the equipment wasn’t stocked at that facility, I was shown the opportunity to order a demo model with full warranty for a significantly reduced price which came quite quickly and was set up at home being enjoyed a few days later. Great customer service.



CHT Solutions has been very prompt to respond and ship the items. I will never hesitate to buy from them again. More power to CHT Solutions!
