Luton, U.K. (July 16, 2004)–PMC has launched its GB1 monitor suited to those seeking a loudspeaker with “a miniature form that does not compromise on performance.” Design cues and the advanced transmission-line technology are derived from PMC’s FB1 and OB1 designs.
The GB1 employs an advanced transmission line with an effective line length of 2.4m (7.8 feet). Drive units consist of the identical 27mm fabric dome HF unit that appears in OB1 and a doped 140mm (5.5-inch) LF unit with cast magnesium alloy chassis. Both drivers have been selected due to their proven capabilities in both consumer and professional arenas.
Sensitivity is high at 87dB 1W/1m. The cabinet consists of 17mm CNC cut Medite panels, balanced veneered both inside and out to guarantee stability. The cross bracing created by the TL labyrinth is 12mm Medite. This combines with precision cut joints, specified glues eradicating the effects of cabinet flex and coloration.
