Very good quality

The sound quality from this sub is far superior to any sub I've ever heard

amazing build quality

Rockford Fosgate r1001-d amp great sound and

Bad ass woofer on a JL mono block JX 500, bought another one and another amp clean low low

Shipping was quick and easy, and the sub was in a well protected box.

I highly recommend a sealed box for this sub

Rockford Fosgate r1001-d amp great sound and

It's so clean sounding, but still packs a punch

make sure you use your multimeter to set the gain to get the correct ac voltage on the amp, won't disappoint at all

Fixed our "blown" speaker........fit perfect.

You won't be dissapointed byt this sub.

Still breaking them in but my inital impression is pretty dang good

This is the perfect SQL woofer
