Nothing wrong with JBL. I still have my 4319 (big) monitors and was thinking of something else until I took them off their low, raked back stands and put them up on some stools and viola!, big time transformation.
I thought I always had enough distance to align myself with the tweeter and mid range but I was wrong. I'll be getting my Wharfedale Linton speaker stands tomorrow to complete things and enjoy what I've been missing all this time.
I figure that I'll be about midway between the tweeter and midrange with the stands.
All the best,
Nonoise
