Visual Sound, Inc. Cinema subwoofer loudspeaker system SB284C

EAW - Eastern Acoustic Works, Inc. For medium to large cinemas. (2) 18-in. woofers THX®-approved. The SB284C cinema subwoofer loudspeaker system uses dual 18-inch cone transducers each mounted in its own optimally vented sub-enclosure to fill large capacity 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.A two-terminal barrier strip -- which accomodates bare wire or tinned leads or spade lugs -- is located on the side of the enclosure for convenient access in cramped installation areas. An additional two-terminal barrier strip is provided to link multiple subwoofers. The use of multiple SB284C's provides even greater output capability and further extends low frequency response. All external components feature a dead flat-black finish to eliminate the reflection of light through perforated cinema screens.
