    U15 D4

    Still breaking in but at low power they are making a beautiful sound. They (2) are hooked to a BC4K. D4S for the win!!!

    Sundown U 15s

    Posted by Jeff LaField on Mar 24th 2019

    I updated from the SA 15s to the U 15s. The U series is awesome in every way, if you are thinking about getting this sub don’t hesitate, this thing hits you in the chest and also hits lows very well. I’m powering mine with an sae 3k, great combination. Great service from Down4sound, JP went above and beyond to help me make my decision, he takes care of his customers and of course is very knowledgeable. Very pleased with the U 15s, get them..
