JBL 2226J 15" High-Power Low Frequency Transducer, 600W Power Capacity, 16 ohms

The JBL 2226J low frequency transducer represents the industry leading results of JBL's engineering research in high power transducer design. The 2226J signified a major advance in speaker design by incorporating JBL's patented Vented Gap Cooling technology in an improved Symmetrical Field Geometry (SFG) magnetic structure. To increase power handling while reducing power compression, JBL engineers have created a unique, direct voice coil-to-air heat dissipation method called Vented Gap Cooling.

This process pumps air through the magnetic gap and directly over and around the voice coil to provide immediate heat transfer and reduction in operating temperature - a direct improvement in power compression. The 2226J incorporates a SFG (Symmetrical Field Geometry) magnetic structure. Computer-aided magnet optimization and analysis allowed JBL engineers to optimize magnet weight, flux density and reduce distortion.
