I use jbl d123's full range on a 24" x 16" OB board,with a jbl 077 for the high end. It sounds great!,but no low bass.I want to try 24",or 30" wide boards.I've heard that mounting the full range speaker off center horizontaly is better for over all sound. Is there a formula for calculating the off center distance for a 24or30" board? Thanks for any advise.- RUDY
