Coaxial Transducers - 2142H, 2152H

The 2142H, 2152H and 2155H coaxial transducers represent the results of JBL's intensive research into the performance and applications of coaxial transducers intended for engineered sound applications. To achieve maximum power handling while maintaining wide bandwidth and consistent dispersion in several critical HF octave bands, JBL engineers developed a new high-frequency dome tweeter, as well as new low-distortion Bi-Radial® horn designs.

In response to consultant and contractor requests, these coaxial transducers were designed to perform well in the most commonly specified utility metal enclosure and baffle combinations, despite the generally detrimental acoustical properties of those enclosures. Custom-build boxes will usually result in better performance characteristics than those published here.
