JBL 2352 Horn
The JBL 2352 is a professional horn/waveguide for 1-inch exit compression drivers. It's an Asymmetric Bi-Radial® horn, so its horizontal and vertical coverage angles differ. Here that means 90° horizontal by 50° vertical. The asymmetric vertical pattern is intentional. You can orient the horn to aim sound more precisely in venues where the listener plane is below or above the horn axis. Mix magazine (July 1995, p.133) noted that proper pattern control is vital for intelligibility in installed sound.
The 2352 belongs to JBL's "2" series of Bi-Radial horns, which use a 1-inch throat. The "3" series has 1.4-inch throats. The stock driver match is the JBL 2425, and the screw pattern is the standard 1-inch driver arrangement. Cutoff is rated at 500 Hz, with coverage extending beyond 16 kHz. Physical dimensions are 22.5" wide by 14.5" high.
The 2352 is a passive component, so there are no power or impedance specs. It's a cast horn, typically used in two-way professional or home systems. One user on audioheritage.org reported crossing a two-way design at 1.2 kHz with a 1-inch driver on the 2352. That same forum is generally favorable: "This is a nice sounding horn," and "Very good sounding horns." Mix magazine (July 1995, p.133) noted the importance of proper pattern control and intelligibility in installed sound, which is what the asymmetric coverage of the 2352 was designed for.
No production years or original price are documented. The record is thin on formal specs - the figures above come from a JBL datasheet reproduced on audioheritage.org. The horn shows up regularly on the second-hand market, often paired with a 2425 driver. Recent asking prices have ranged from €250 for a pair up to €450 for a horn-with-driver combo.
