Technical Specifications CB152
COMPONENTS & CONSTRUCTION
The CB152 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 CB152 requires an external active electronic crossover. The
recommended crossover point is 1200 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.
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.
