The JBL 2241H low frequency transducer represents the results of JBL’s industry-leading engineering research in high power transducer design. The 2241H signified a major advance in speaker design by incorporating JBL’s patented Vented Gap CoolingTM technology in an improved Symmetrical Field Geometry™ (SFG) magnetic structure.
 
To increase power handling while reducing power compression, JBL engineers created a unique method called direct voice-coil-to-air heat dissipation (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.
 
Through the use of computer-aided magnet optimization and analysis techniques, JBL engineers were able to optimize both magnet weight, flux density and field saturation resulting in a significant reduction in harmonic distortion. This new magnet structure offers much of the weight advantage of rare earth magnet structures without the higher cost.
