The THX Ultra2 certified JBL Synthesis SK2-3300 LCR has technology based on the flagship Project Everest. Sporting dual 10" woofers plus two ports, a heavily braced enclosure with a curved front baffle, and dual binding posts plus horn-loaded midrange and ultra high-frequency drivers with extension all the way up to 50kHz. The 1" ultra-high-frequency beryllium diaphragm driver is paired with a 60x30 degree JBL Bi-Radial horn. The horn shape is designed to increase off axis response as horn-loaded drivers are known for their directionality.

The 10" woofers are treated with JBL's Aquaplas material, has dual 3-inch heavy-duty edge-wound voice coils, neodymium motor structures, and cast-aluminum frames.
