The JBL 2241G/H low frequency transducer represents the results of JBL’s latest engineering research in high power transducer design. The 2241G/H signifies 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 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.
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 2.6 kg (6.5 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 the prohibitive cost.
