PRODUCT INFORMATION
APPLICATION
• For subwoofer channel of cinema soundtrack
• THX® approved
The SB284C cinema subwoofer loudspeaker system uses dual 18-in
cone transducers each mounted in its own optimally vented suben-
closure to fill large capacity theaters theaters with high definition
sub bass information at earth-shaking output levels. This system has
been approved by the THX® division of Lucasfilm, Ltd., for use in THX
certified theaters.
The SB284C’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.
Each 18-in woofer is individually accessible via a two-terminal bar-
rier strip, which accommodates bare wire, tinned leads or spade lugs,
located on the side of the enclosure for convenient access in
cramped installation areas.
The use of multiple SB284C’s provides even greater output
capability and further extends low frequency response.
