Hi, Could anyone help me identify these speakers? They are the Sony SS-C510AV tower speakers, I tried all kinds of searches on the Internet, to no avail. They are approximately 3.5/4 feet tall and use three drivers, includiang an oversized one for bass (probably 12", but I could be wrong, haven't seen my 12" sub driver in a long time so can't compare). Their max power handling capacity is 270W, according to the back of the boxes. I need to get some specs or data on them, most importantly how much they used to cost new, because I will be selling them after I get my RF-7s... I'm sure at least ONE of you guys has come across info on those speakers. At least to what range of Sony speakers do they belong, the crappy one or the REALLY crappy one? Thanks and merry Christmas to all!
