JBL 2350 Bi-Radial Horn
The JBL 2350 is a two-way professional studio monitor horn built around JBL's constant-directivity Bi-Radial technology. It paired a 1-inch exit compression driver with a 10-inch woofer. JBL built on this design for its later studio monitoring horns. The 2350 was used as a component of the JBL 4400 series studio monitors. Enthusiasts regard it as a classic, and one forum owner calls it "an excellent performer" that is "very dynamic and detailed," with great imaging.
The horn covers 500 Hz to 2.5 kHz, with a sensitivity of 112 dB SPL and an 8-ohm impedance. It's rated for 75W/100W program and 150W peak. It measures 19.3" x 17.5" x 16.9" and weighs 26 lbs. Recording Engineer (April 1981, p.51) ran JBL's promotional material for the 2350 paired with the 2324A adapter. The ad showed on- and off-axis response curves alongside the company's new 2441 compression driver.
The sources available don't document production years or original pricing. They also don't record the exact woofer and compression driver models. The 2350 was sold as a horn assembly meant to be paired with JBL's appropriate drivers.
