PSB GB1 User manual

PSB G-Design
For thirty-five years, PSB has been praised for delivering the best value
in high-performance loudspeakers. Speakers that are more musically
transparent. More dynamically honest. More true to nature – neither
adding nor taking away from any sound. And more technically rigorous,
and more carefully designed, built, and finished. Continuing this
tradition, PSB G-Design models,
GT1
,
GB1
and
GC1
share more than
just a name and family resemblance. Each one represents a ground up
engineering effort by Paul Barton and his team, and continues a thirty-
five year legacy that has earned PSB the praise of critics, audiophiles,
and music and film lovers from around the world.
PSB G-Design consists of the
2-1/2
-way
GT1
Tower, the
2
-way
GB1
Monitor and the
2
-way
GC1
Center Channel. All three models
are comprised of heavily braced solid MDF cabinets. These rigid,
resonance-free enclosures are finished in an elegant, hand-rubbed,
furniture-grade seamless high gloss. The G-Design
GT1, GB1
and
GC1
share a highly evolved
1
” aluminum-dome tweeter – like each and
every PSB driver, a completely proprietary design – with a unique
combination of performance factors. Exceptional extension yields
outstanding accurate treble, tremendous dynamic linearity delivers
the clarity of details both loud and soft for which PSB speakers are
Platinum Series woofers that employ high quality
woven fi berglass cones have been used on all three
G-Design models.
PSB G-Design uses a
1
” aluminum dome tweeter
with neodynium magnet. An integrated heatsink
assures stable output levels.
For home theater and serious music listening alike,
demand high impact, accurate ultra-deep bass from
powered subwoofers like the SubSeries 6i (left) and
SubSeries 8.

famous, and unusually even, broad dispersion promotes superbly true-
to-life “soundstaging.”
The
GT1
and
GB1
feature
6.5
” woofers (two on the
GT1
and one on the
GB1
) while the
GC1
uses two
5.25
” woofers. For use in home theater
applications all models have been video shielded. The woven fiberglass
woofers are engineered for dynamic range, controlled expression, and
exceptionally linear high-output reproduction. Together, these superb
transducers enable the G-Design models’ smooth, accurate reproduction
and remarkable dynamic potential. Combining this with our never ending
quality control – we compare each speaker to its reference standard, a
much over-looked but crucial factor – to yield consistently matched
speakers. This, in turn, produces the PSB G-Designs’ wonderfully
natural, stable and precise spatial qualities.
The same characteristics that make the G-Design
GT1
and
GB1
excellent
stereo speakers make them superb anchors for a multi-channel home-
theater system: exceptionally accurate tonality, tremendous dynamic
range, superb clarity and detail. But truly excellent multi-channel sound
demands companion speakers of equal quality, meticulously “timbre-
matched” to preserve the consistent tonality and dimensionality so
critical to convincing surround-sound reproduction. This is achieved
with the G-Design
GC1
center-channel speaker. The
GC1
delivers the
high efficiency and wide dynamic range required by a center channel in
a home-theater system. Its complex drivers-cabinet-crossover system is
extensively fine-tuned for accurate timbral-matching to the
GT1
and
GB1
.
Less obvious but just as important, Barton was equally careful to ensure
complementary dispersion and spatial response for seamless “front-
stage” imaging. Experience your favorite music and film soundtracks in
all their glory on the PSB G-Design models to understand how PSB has
taken performance to new heights of excellence.
