cerwin vega comparison

hey there, wondering if anyone out there has ever compared the older E-712 model to the somewhat newer 
CLSC 10 model

I own a pair of the E-712. one needs a tweeter replacement. looks like id be in about 80 bucks when its all said and done to repair it. there is a local guy selling a pair for clsc 10 for 300 bucks OBO. wondering if it might be a better option to just buy those?

anyone have any thoughts??
