• For subwoofer channel of a cinema soundtrack

The SB184C cinema subwoofer loudspeaker system uses a high power
18-in cone transducer mounted in an optimally vented enclosure to
fill small to medium capacity theaters with high definition sub bass
information at earth-shaking output levels.

The SB184C’s optimally vented enclosure uses enclosure resonance to
increase sub bass response while limiting driver excursion. This
method produces less distortion and minimizes driver strain while
extending sub bass response to the lower limits of human hearing.
Special effects will have greater clarity, greater power and greater
impact.

A two-terminal barrier-strip, which accommodates bare wire, tinned
leads or spade lugs, is located on the side of the enclosure for
convenient access in cramped installation areas.

The use of multiple SB184C’s provides even greater output
capability and further extends low frequency response.

COMPONENTS & CONSTRUCTION

The SB184C is a high output, extended bandwidth subwoofer
optimized specifically for cinema use. It features a high power 18-in
low frequency transducer mounted in an optimally vented enclosure.

The enclosure is constructed of 3/4-in Medium Density Fiberboard
except for the baffle plate which is 15 mm, void-free, gross-grain­laminated birch plywood. Extensive internal bracing is employed to
minimize panel resonances resulting from the large acoustical
energies generated within the enclosure and maximize acoustical
energy transfer.

Input connectors are 2-terminal barrier strip, designed to accommo­date bare wire, tinned leads or spade lugs.

All external components feature a textured, non-reflective, black
finish to eliminate reflection of light through perforated cinema
screens.
