JBL’s rugged DuraFlex™ finish. The attractive CNC-machined, 16-gauge steel  
grille wraps around the sides of the enclosure so there are no protruding lips  
on the front of the box to create acoustical interference. The grilles are  
internally lined with acoustically transparent foam to provide additional driver  
protection and give a very professional appearance.

capable of reinforcing bass and kick  
drum or playing high-level music in
