Technical Specifications CB2591 CINEMA SERIES

COMPONENTS & CONSTRUCTION

The CB2591 is a two-way, high output, full range loudspeaker system intended for use in behind-screen cinema applications. It features dual 15-in low frequency transducers mounted in a compact, vented enclosure and a 2-in exit titanium diaphragm compression driver mounted to a large format 90° x 40° constant directivity horn.

The CB2591 requires an external active electronic crossover. The recommended crossover point is 500 Hz. Input connectors for the HF section are dual spring loaded push-button type, designed to accommodate bare or tinned leads, with a 2-terminal barrier strip for the LF section. Separate input connectors are provided for each section.

The low frequency enclosure is constructed of 3/4-in thick Medium Density Fiberboard (MDF) with the exception of the baffle which is 15mm void-free, cross-grain-laminated Baltic birch plywood. Exten- sive internal bracing is employed to minimize panel resonances resulting from the large acoustical energies generated within the enclosures.

The high frequency horn is constructed from a specially dampened fiberglass which is non-resonant, lightweight and non-reflective.

The adjustable mounting bracket attaching the HF horn to the LF enclosure can be positioned at one of three mounting points for optimum HF horn placement. It allows the HF horn to be aimed independently of the LF section in both the horizontal and vertical planes and can be locked once it is positioned.
