- Vented enclosure maximizes output
General Application
Description
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 accomodates bare wire, 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 SB184C?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.

The S8018 II high-efficiency subwoofer is the ideal low-frequency extension to complement RCF installed systems.
The low-frequency transducer is a hypervented vented, high excursion RCF Precision 18” woofer with a 4” inside/outside voice coil to minimize power compression and extend the life of the product.
Using bass-reflex loading the subwoofer design ensures an efficient acoustic response down to 30 Hz. The Baltic birch plywood enclosure is painted with black, heavy duty, textured epoxy. The front is protected by a strong powder coated metal grille. The cabinet features two Neutrik Speakon™ connectors in a recessed input plate. A M20 pole mount adaptor is provided on the top of the cabinet, integrated hand carry points on the cabinet sides.

The Sub 2.18 is a double 18“, high-power subwoofer for very high sound pressure levels: sensitivity 102 dB 1W / 1m, max. SPL 138 dB.
Boasting power handling of 1000W continuous and 4000W peak, the Sub 2.18 can be used universally for active two-way or three-way systems.
It is above all, however, the ideal companion to the C 25.2 for the creation of an active two-way system together with the DSP 260 or DSP 600 controllers and power amplifiers from the SL or LX series.
For easier transport, the Sub 2.18 is prepared for the optionally available DC-WK-C18 wheel kit.
