I think I might have blown my PS-1000 today during the opening credits of Gladiator. I seen no visual damage to the woofer itself but it is making a very loud vibrating noise when I have it cranked fairly hard during the opening credits of Gladiator. It looked like it would be very simple just to put in a new woofer in the old ones spot. Does anybody reccomend doing this? If so what should I replace it with? Do you think it would sound any good? Thanks. Kevin C.
