Details
JBL models 2352, 2353, and 2354 are medium format elements of JBL�s preeminent family of Bi-Radial� horns, providing uniform coverage control over the bandwidth of 630 Hz to beyond 18 kHz, allowing precise control of critical vocal range energy. These medium format horns provide extremely low distortion at typical peak sound pressure levels of 139 dBSPL at 1m. Optimized Aperture The clear and uncolored sound character of the 2350 Series horns is accomplished by coupling the compression driver phase plug to a unique horn throat geometry, resulting in the elusive combination of extremely low throat distortion with high air movement capability. These horn designs were verified through the use of advanced technology, including finite element analysis, boundary element analysis and extensive computer modeling via proprietary JBL horn design software. Components and Accessories The 2350 Series of horns were designed to be used exclusively with either the 2447 or 2451 compression driver. The 100 mm (4 in) diaphragm for this driver utilizes a three-dimensional diamond pattern surround and a pure titanium diaphragm for rigidity and freedom from breakup modes. With its 150 watt continuous program rating above 1 kHz and optimized phase plug design for low distortion, smooth response and wide bandwidth, it matches with the 2350 Series horns for high sound pressure level applications. The 2510 mounting bracket is recommended for suspension of the horn/driver combination. The 2510 installs between the horn flange and driver providing multiple pickup points.
