I'd guess similar...
The Cerwin stuff is generally LOUD, not about sound QUALITY. The new model looks to be similar in that department. Based on history, I'd guess these aren't any more accurate, but still loud, so whether you think they sound BETTER will depend a lot on your personal ear/brain combination.
Bottom line: ya gotta listen for yourself. Or what the heck, just buy 3 of the new one for the front and move your current models to the rear for 5.1!
