Meh.
I needed these for an underseat box, which they're designed for. They have decent output, nothing mind blowing. The box is built to specification but the low end is pretty lacking. Not gonna lie, I expected more from Sundown. Product shipped quick, good on D4S, but that has no real impact on the quality of the product.

SD-4 10" D4
WOW!!!!! Highly impressed with this sub! Hits pretty hard for a shallow mount sub with the right box! Will recommend this to anyone who has limited space!
