These low-frequency transducers incorporate JBL’s

patented Vented Gap Cooling technology in an

improved Symmetrical Field Geometry (SFG)

magnet structure.JBL engineers optimized both

magnet weight,flux density and field saturation

resulting in a reduction of overall driver weight and

a significant reduction in harmonic distortion.

The 2242H low-frequency transducer incorporates

JBL’s patented Super Vented Gap

technology for

improvement in power handling capability while

minimizing power compression.

(4 in) diaphragm design includes JBL’s exclusive

three dimensional diamond pattern which

increases the drivers’output in the 5 kHz to 20 kHz

range when combined with the Coherent Wave

phasing plug.

49 mm - 2" EXIT CO M P R E S S I O N D R I V E R S

(100 mm - 4" Diaphragm)

The 2446H/J and 2450H/J use the optimized

configuration of the Coherent Wave phasing plug

design, offering coherent summation of acoustical

power up to much higher frequencies than

previous designs.

The 2450H/J incorporates a neodymium rare-earth

magnet assembly that provides the equivalent

electromechanical conversion efficiency at two-

thirds the size and one-third the weight required

by previous large format compression driver

designs.
