This unit uses JBL's unique low-distortion SFG magnetic circuit, as well as a long voice coil and finely designed suspension mechanism to enhance linearity.
A horn type tweeter 2404H is installed in the high range.
This unit uses a biradial horn to realize a wide service area of 100 ゜ x100 ゜ and to suppress the generation of harmonic distortion.

The enclosure is built for durability and is made of 19 mm thick rigid multi-layer plywood with an exterior polyurethane coating for added strength.
