Cabinet Enclosures Kempton’s GT Series injected moulded polypropylene enclosures feature an original proprietary cabinet design with smooth and flowing lines that immediately identifies the GT series appearance from the many Competitors models that look very much the same. The GT Series enclosures rugged construction and exterior finish were designed to handle the rigors of the road when used for portable sound reinforcement applications. Shape The Asymmetrical trapezoidal shape design provides a 45° taper angle for stage monitoring applications as well as for a general Front of House P.A. system Pole Mount Sockets & Handles For speaker stand mounting all GTs are equipped with a 35mm Ø (13/8”) aluminium pole mount socket. The GT Series models feature ergonomically placed carrying handles for a balanced “feel” when handling / transporting. Grilles Extremely rugged 1.2mm (0.05”) steel grilles protect the woofer without detracting from its sonic performance in any way. Rigging/Fly points & Stacking capabilities All GT enclosures are provided with multiple M10 fly points to accept standard M 10 eye-bolts to facilitate safe and easy flying capabilities. The enclosures are equipped with rubber feet and stacking positions that are moulded into the cabinet enclosures, allowing stable stacking of 2 cabinet enclosures. Power Amplifier (GT12A) The bi-amplification system of the GT12A consists of two independent Class AB amplifiers, one for the LF woofer and one for the HF compression driver/horn. Independent LF & HF Thermal and shortcircuit protection circuits are also featured. The Crossover circuitry features an active electronic 24dB/oct Linkwitz-Riley design. The innovative 2channel on-board mixer (CH A and CH B) with each one featuring: Preamp Gain, Volume, High Frequency EQ, Low Frequency EQ controls, XLR/Jack combo inputs. An XLR-M output jack provides mixed signal output of input channels A and B. Passive Version (GT12) The GT12 Passive speaker features professional 2 x 4-pin Speakon connectors mounted to a recessed panel to prevent inadvertent operation. Components All components were carefully selected and manufactured to Kempton’s specifications and tolerances and then severely tested for reliability for the Kempton GT Speaker series. The custom designed Woofers feature high strength curvilinear cones on steel chassis ferrite frames, high temperature resistant voice coils to prevent burnout failures and ferrite magnet structures to produce solid low frequency response. The HF compression drivers provide clean and clear high frequency output and are coupled to an 80°H x 50°V custom designed constant directivity horn for precise dispersion. Crossover Networks The Heavy Duty Crossover Networks that divide the signal going to the woofer and compression driver are constructed with oversize coils, high voltage capacitors and power resistors to provide the best possible sound quality and minimize signal loss. Independent LF and HF overload protection circuits are employed to protect the woofers and HF drivers from failures.

Cabinet Enclosures 15mm, (5/8”) plywood is used in the construction of cabinet enclosures on all models except for PW 218 which has 18mm (3/4”) cabinet enclosure. The use of solid glue joints and the critical placement of internal bracing results in enclosures that virtually indestructible as well as resonance-free. Shape: Maximum Versatility The Asymmetrical trapezoidal design shape with a 45° angle provides for Stage Monitor use and Front of House applications (PW10-PW12-PW15). Finish Durable textured black paint is used to withstand to the rigors of the road when transporting and provide a stylish appearance for permanent installations. Pole Mount Sockets & Handles For speaker stand mounting, all PW models are equipped with a 35mm Ø (13/8”) aluminium pole mount socket. Ergonomically placed integrated handles are built into the 100% plywood structure of the cabinet enclosure. Heavy Duty Grilles An extremely rugged 1.2mm (0.05”) steel grille with high aperture ratio protects the speakers without detracting from their sonic performance in any way.
