Phrases like articulate, powerful, punchy and expressive have been impartial comments made about the original GB1. Now with the extensive upgrades that bring it to i status its performance levels exceed the expectations of the most demanding critic. Its slender form blends seamlessly into any modern interior and does not suggest the sheer level of performance it achieves. It belies its size in both depth of bass and the scale of image taking any music or movie material in its stride.

The GB1 was born out of two award winning PMC loudspeakers, the FB1 and OB1. The technological advances in ATL™ design in these models provided a platform for the radical GB1 design and the similarities in their sound signatures are clear. Vocals are natural and supremely well defined with an amazing ability to produce breathtaking levels of controlled bass.

The GB1i is highly versatile in both stereo or surround set ups and is suited to modest spaces or open plan rooms either free standing or in close proximity to a rear wall.

Customer Reviews

"They sing amazingly well straight out of the box "
Mr L, Helsinki
"I was listening to many speaker and different brands prior to purchasing my PMC GB1i's. There was something about them that made me smile. They are 'musical' speakers, which is a rare talent even with today's 'sea of choices' "
Mr R, Canada
"Very impressed, for a small speaker these do the heavy lifting. I chose GB1s because these are the only small speakers I have found that reproduce piano realistically across the instrument's register and the design is neat and unassuming. "
Mr D, Hove
"Fantastic performance from such a compact speaker. "
Mr H, Doncaster.
"I love the sound the pair of GB1i produce: details, tight bass... This pair may be the best I have owned up to now "
Mr V, Vietnam
"Excellent rendition of Classical, Vocal & Jazz. Will buy more PMC speakers for the AV room. "
Mr P, Bolton
