We'll send you an email when JBL 2242H 18" Maximum Output LF Driver 8 Ohm is back in stock or available for preorder.
The 2242H is ideal for use in high output subwoofer systems with bass extension to 25 Hz. The total peak-to-peak excursion of the 2242H is 18 mm, within 10% linearity. The Super Vented Gap™ (SVG) series of low frequency transducers takes the patented Vented Gap Cooling™ (VGC) heat dissipation process one step further. A completely new motor structure design extends the pole piece above and below the top plate to improve gap flux symmetry and increase thermal conductivity from the voice coil to the pole piece. In addition to the benefits of Symmetrical Field Geometry™, these transducers also incorporate a copper shorting ring that is imbedded in the pole piece at the precise center of the gap and in close proximity to the voice coil. This ring results in a reduction of third harmonic distortion and a reduction of voice coil inductance, which improves the transducers' transient response.
