oh, yah.... the studios... i had a 10" dealer demo (never actually used) the owner gave me for 100 (were going to be sold for 300) i don't think the line really ever got out there. there were the silver-coned dei subs that were basically viper subs. nothing real special. my sis had a pair of those 15's, and must have been in a bad box. anyways, if you come across a dei studio, i want it. the one io bought was basically stolen when i loaned to to my sister, along with a cirwin vega i had. i would call it "sql"? circa 2001/02, i think. still look at the magnet boot on the sub shelf and shake a fist, lol.
