B-52 SH-Series subwoofer enclosures provide the advantage of low-frequency horn loading from compact and cost effective cabinets which are suitable for a wide variety of high output applications. SH-Series enclosures provide enormous output, high efficiency, low distortion, increased headroom, wide dynamic range and superior transient response with an up to 9dB higher maximum acoustic output capability than any single direct radiator system

CONSTRUCTION

The SH-Series cabinets are constructed of void-free, seven layer, 3/4" plywood for maximum rigidity and minimum weight. Sanded 3/4" Medium Density Fiberboard is used in the porting chambers. Reinforced internal bracings are used to fortify each enclosure. Joint-filling adhesive and silicone is applied to the internal joints of an enclosure to avoid the possibility of air leakage. The porting chambers are finished with three durable paint layers which helps protect the wood and increases the cabinet’s road-worthiness.

All three ruggedly built enclosures house 100% made in the U.S.A. 18" cast subwoofers, with 4" high-temperature, precision-wound, polyamide voice coils employed in the SH-18X & SH-1818X models. A contemporary look incorporates the use of a 3/4" thick, tinted plexi-glass window that reveals the subwoofer(s) at work. The plexi-window also protects the drivers from the elements - such as rain, sun or spilled drinks

Finish:  Each cabinet is finished in rugged, impact-forgiving black carpet. Available in other finishes through our Sound Contractor’s division

Connections:  Steel input connection plates include (2) metal 1/4" phone jacks and a NL4MPR 4-pin Neutrik brand speakon connector.

Accessories:  Each cabinet includes 4" heavy-duty casters for easy mobility, steel bar handles and is reinforced with steel corners.

SH-18 is a relatively small enclosure perfect for medium to long-throw applications. Using the B-52 18-180 subwoofer with a 3.5" polyamide voice coil and a 180oz magnet structure, the SH-18 can deliver rock solid lows that can shake any dance floor.

The SH-18X subwoofer is designed for high SPL, ideal for medium to large venue environments. In smaller venues or playback applications the SH-18X can be located on the floor or in corners of the room for increased subwoofer impact. In outdoor applications, the long-throw, folded-horn design reaches a far greater distance than any direct radiator system. The SH-18X offers high efficiency and directivity which also make it ideal for large indoor sound reinforcement where voice articulation is a concern. The SH-18X is engineered to complement any powerful B-52 full-range system.

SH-1818X folded-horn design is extremely powerful and relatively compact for a dual 18" subwoofer. While the speakers are connected in parallel, precision placed internal dividers allow each driver to fire into the central chamber without any cancellation. With over 2000 watts continuous program power handling the SH-1818X can add earth shaking bass to any system. With this cabinet we really do recommend reinforcing your stage or dance floor!!!

CONSTRUCTION

Each system is constructed of void-free, seven layer, 3/4" plywood for maximum rigidity and minimum weight. Reinforced internal bracings are used to fortify each enclosure. Joint-filling adhesive is applied to the internal joints of an enclosure to avoid the possibility of air leakage. Internal acoustic dampening is applied to all cabinets to minimize adverse reflections resulting in a smoother frequency response. Enclosure venting extends the low frequency response and minimizes distortion caused by excessive driver excursion.

DJ-Series Componets

Woofers: Woofers used in the DJ-Series are 100% made in the U.S.A. with high temperature, precision-wound polyamide voice coils which provide superior electro-mechanical energy conversion and maximum heat transfer.

High-Frequency: Compression drivers are used for high-output presence and clarity. The diaphragms are made from extremely rigid titanium for extended high-frequency response and smooth, accurate transients.

Crossovers: Customized crossover networks are engineered for maximum output and frequency coverage. Only high quality, low-loss components, such as low-dissipation polypropylene capacitors, high-power ceramic resistors and high-saturation level inductors are used in the B-52 crossovers.

DJ-Series Features

Connections: Steel input connection plates include (2) metal 1/4" phone jacks and a NL4MPR 4-pin Neutrik brand speakon connector.

Accessories: Each cabinet includes 4" heavy-duty casters for easy mobility, steel bar handles and is reinforced with steel corners. The DJ-212 does not include casters but has a pole-mount stand adapter.

Finish: Each cabinet is finished in rugged, impact-forgiving black carpet.

The DJ-212 is ideal for small live stage venues where a powerful cabinet is needed and limited space is a key factor. The DJ-212 offers high power handling and efficiency from an exceptionally small enclosure. The DJ-212 includes a pole-mount stand adapter.

DJ-215 includes a large horn with a 90°x40° dispersion angle, a titanium diaphragm compression driver and a B-52 15-120 woofer with a 3" high-temperature polyamide voice coil and 120oz magnet assembly.

The DJ-218 combines the B-52 18-180, cast aluminum frame with 3.5" polyamide voice woofer and a true titanium diaphragm compression driver. The DJ-218 is a large cabinet that has enormous output for those who like a system with deep, tight bass.

The DJ-1515 is the largest full-range DJ-Series system with over 800 watts continuous program power handling. The B-52 Comp-2 titanium diaphragm compression driver provides smooth highs while the dual B-52 15-120, 3" polyamide voice coil woofers deliver earth shaking bass.

19K Hz with a built-in customized passive crossover designed for high power handling with a 12dB/octave slope. The 90°x40° wide dispersion angle horn has great coverage both on-axis and off-axis.

18-180 woofer with a cast aluminum frame, precision- wound 3.5" polyamide voice coil and a vented magnet assembly which help dissipate generated heat, the DJ-118 can produce deep thundering bass with a usable frequency response.

Utilizing the B-52 18-180 woofer, a 10" midrange housed in a damped and sealed subenclosure and a titanium diaphragm compression horn, the DJ-318 was designed for large venues where wide coverage, extremely high output and a powerful bass response is required. The DJ-318 produces a remarkable full-range response and sonic accuracy by combining rock solid low end, smooth mids and detailed, yet pristine highs.
