JBL 2206H

The 2206H/J incorporates JBL’s patented Vented Gap Cooling technology in an improved Symmetrical Field Geometry (SFG) magnetic structure.  Vented Gap Cooling is a unique, direct voice coil-to-air heat dissipation method that increases power handling while reducing power compression.  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.

Through the use of new computer-aided magnet optimization and analysis techniques, JBL engineers were able to optimize both magnet weight, flux density and field saturation resulting in a 1.8 kg (3.9 lb) reduction in overall driver weight and a significant reduction in harmonic distortion. This new magnet structure offers much of the weight advantage of rare earth magnet structures without their prohibitive cost.
