I’ve got original Model 5’s and have tried the rear tweeters on several occasions, but always think it is too bright. My room is small and there is a concrete block wall behind the speakers so any rear output gets reflected back. I did have some cotton tapestries directly behind the speakers but that didn’t really change the results.
Vandersteen Question
....just wondering if anyone uses the rear firing tweeters on the big Vandersteens. Richard designs these with equal phasing....doesn't that rear speaker ruin things?
