link is dead but if its the square jackhammer than its a piece of sh!t just like the original Jackhammer. Its a joke of a subwoofer.
Only engineers that have been able to pull off the squares with any real hope of making them kill is the kicker boys!! WOO!! who else makes squares? i know of MTX, Pyle kick, and hifonics (i think)
i thought the square mtx's sounded perty good, but im a mtx fan myself. hifonics did make a square sub. i beleive my buddy had 13'' square subs. i thought it was kinda weird.
