Very comparable. The hx2's are vicious when it comes to low end bass. Throw'em in a 2 cube ported box to 35-40 you'll be grinning from ear to ear. They take a good amount of power too, as long as you know what you're doing you can throw 1.5 times - 2 times the rated power at'em. Can't beat them at this price. And these are alomst brand new, I should know I used to own'em.
