this disappoints me, you should see how good the inside of their speaker boxes look and you would understand why.
come to think of it the whole port noise may be caused by the port being stuck inside that little crevice, i always noticed the chuffing came from inside the port not the opening. if anyone owns one of these subs and has the tools to do this i would be very interesting in seeing how much of a difference it would make side loading the port rather then front firing.
