Hertz SPL Show SX300 From Accutek, Hampshire
The brand new show-stopping Hertz SPL Show SX300 stocked by FOUR MASTER, Accutek in Hampshire is well worth checking out. Designed in the Hertz tradition, this ground shaker is built to provide system builders with bundles of bass whilst looking drop-dead gorgeous. Designed for competition and extreme SPL performance, the SPL Show SX300 is described by Hertz as an “Acoustic Pressure Generator”. The SX300 is a 12″ dual 2 ohm voice coil subwoofer with an exceptionally light, four layer voice coil assembly on a 40mm aluminium former offering exceptionally rapid excursion resulting in more air movement and extreme efficiency.
The unique dual spider design ensures extreme control and linear movement of the cone even during maximum cone excursion conditions. This results in incredibly accurate and surprisingly musical reproduction of sub frequencies with very low distortion. A triple magnet assembly also aids with accuracy under high SPL conditions and the unique back vented spider support system, consisting of vertical holes which drive air directly over the voice coil ensuring effective coolong without discenible compression.
Despite the technology on board, these subs add attractive styling to any installation whether mounted cone or magnet facing outwards. Accutek has competed in UK rounds of the European Mobile Media Association’s sound-off format and are well placed to help their customers build class winning SPL or SQ systems. Coupling Accutek’s skills with this state of the art subwoofer should help propel them to the forefront of the growing number of FOUR MASTER competiton car builders.
