Key Features: 44 mm (1.75 in) Pure Titanium Diaphragm HF Compression Driver Flat-Front Bi-Radial® HF Horn Sensitivity: 102 dB SPL 1 W, 1 m (3.3 ft) Power Capacity: 150 W IEC Pink Noise Integral Transformer Mounting Bracket
The JBL 2155H Coaxial Transducer represents the results of JBL’s intensive research into the performance and applications of compressiondriver coaxial transducers intended for engineered sound applications. To achieve high acoustical power output capability while maintaining smooth response, wide bandwidth and consistent dispersion in several critical HF octave bands, JBL engineers used advanced CAD techniques to apply low-distortion Bi-Radial® horn architecture to a coaxial system, and then combined the new horn with JBL’s 2416H High-Frequency Compression Driver. The 2416H incorporates a pure titanium diaphragm with JBL’s patented “diamond surround” for control over secondary resonances, extended frequency response, and greatly reduced mechanical fatigue. A copper shorting ring on the pole piece controls high-frequency impedance and further improves highfrequency response. The low frequency driver combines a rugged die-cast frame with a specially designed cone and 76 mm (3 in) edge-wound aluminum ribbon voicecoil motor structure. An integral transformer mounting bracket is preattached to the LF transducer frame and also allows quick access to the crossover network.

2155H 380 mm (15 in) Coaxial Transducer In response to consultant and contractor requests, the JBL 2152H was 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 peformance characteristics than those published here.

New materials, production methods, and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current JBL product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated.
