Absolutely stunning performance.

Running 2 in a vented box .86cf per sub tuned to 35 hz. The performance is down right stunning when you realize it's just 8s. It did take a while to tune, but all around amazing sound quality from a little package.

Great sound quality

It has Fantastic sound and build quality for an 8" subwoofer. I have it in a single cubic foot ported box and it has great sound quality and still plays loud as well. It has plenty of bass for smaller SUVs like my Jeep Patriot. It's quality was quite surprising and impressive. Image dynamics definitely makes a great product.
