The GB1 was born out of two award winning PMC loudspeakers, the FB1+ and OB1. Technological advances in ATL™ design provided a platform for the radical GB1 design, including the driver and cutting edge crossover techniques seen in the + models.

The GB1 has a slender form factor, ideally suited to modern domestic environments, but the GB1 belies its size and takes any material in its stride. From Copeland to Kraftwerk, it reproduces a soundstage on a huge scale, with superb bass energy and imaging. Critics have praised not only the low frequency depth but also the astonishing midrange and high frequency clarity that make any performance with vocal accompaniment truly captivating.
The GB1 is highly versatile and suited to modest studies or open plan rooms, either free standing or in close proximity to a rear wall.
