“What is the optimum size sealed enclosure for the JBL GX1200? Does it make a difference to run the subwoofers 2 ohm or 4 ohm?”

• 1cu ft. is the recommended sealed box size. Running a 2 ohm load to the amp would typically give more power to the subs

• Our JBL GX1200 can only run at 4 ohms. The optimum volume for a sealed enclosure is 1.70 ft3
