Technical Specifications CB152x CINEMA SERIES

COMPONENTS & CONSTRUCTION

The CB152x is a two way, high-output, full range loudspeaker system intended for use in behind screen applications. It features a 15-in low frequency transducer mounted in a compact, vented enclosure and a titanium diaphragm compression driver mounted to a large diaphragm, 1.4-in throat, 90° x 90° coverage pattern, constant directivity horn.

The CB152x's internal passive LF/HF crossover filter network allow the system to be powered by a single amplifier channel with no external active electronic crossover. The input connector is a 2- terminal barrier strip located on the LF section. A "jumper cable" is provided to continue the signal chain to the HF section.

The low frequency enclosure is constructed of 3/4-in thick Medium Density Fiberboard. Extensive internal bracing is employed to minimize panel resonances resulting from the large acoustical energies generated within the enclosures. The enclosure and all external parts are coated with a black finish.

The high frequency horn is constructed from a specially formulated structural polyurethane foam which is non-resonant, lightweight and non-reflective. The LF enclosure has 2 mounting points on both top and bottom to allow optimum front/rear positioning of the mid/ high component for either right or left channel. The adjustable steel bracket attaching the HF horn to the LF enclosure 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.
