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.
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.
