Technical Specifications CB152x
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.
