I need help finding out what model these are. They were a gift from a relative who didn't need them any more. I need to know what they are so that i know how much to ask for them as they cannot take my Sansui amp's wattage. they measure abt 13" tall by 7 3/4" wide by 9 3/4" deep. They came with a matching Paradigm PDR-10 subwoofer.
