Found curbside for 12 bucks. Cabinets and grills in good shape. Main woofers need new surrounds. Can anyone tell me the specs on this set?? Also, they don't seem to have the normal phillips head screws for removing the drivers; any idea what they use and what size?? Oddly enough, they had the little tabs one would put on the bottom of a speaker on the Top of one. Wonder if somebody once had 2 pairs and "stacked."
