Since I've upgraded the front side of my ML system (ESL 15, Illusion), I'm wondering about the rear side which is currently running Script i speakers. As far as I know there are no issues, other than they were installed in 2006 so the panels are starting to age. The way I see it, I could re-panel my Script's, or replace them with a new pair of ML EFX. I checked with ML and Script i panels are $995, so it would seem like a bargain to just re-panel my existing Script i's. Other than the woofers, I would have 'new' speakers, and they would already be installed. Since the specs are 'essentially' the same between these models, is there a reason why I should consider replacing my existing Script i's with the EFX... as opposed to just re-paneling them?
