I have a pair of JBL L-250's and am wondering if anyone can advise me on how to optimise bass from these cabinets. Right now I have them 17" from the back wall to the back of the cabinet and about 30 " from the side wall. Distance between them is 8 feet. Am I doing something wrong with my placement ....the bass is really weak in presence and no matter where I place them it doesn't seem to improve.
Any input is appreciated.
