PSB 6919217, Owner'S Manual

Page: 3 / 27

Congratulations on purchasing your new PSB Synchrony loudspeaker.
We hope that you enjoy our product for many years to come. This
owner's manual will give you many useful tips about connecting, placing
and using your loudspeaker. We recommend you read it thoroughly and
it should answer all of your product related questions. If not, feel free to

Synchrony design background
A little technical background might give you an appreciation of the
technology that went into the design of your Synchrony product.
Our intention in designing the PSB Synchrony range of products was to
bring to bear all that we have learned in 35 years of crafting fine
loudspeakers to create a line of high performance systems of truly
elegant design.
The Synchrony models use advances in three core technologies, the
cabinet, the drivers, and crossover design.
THE CABINET
Cabinets for a high performance loudspeaker must be heavy, rigid and
vibration free. Sound must come from the drivers only, never from the
cabinet itself.
Cabinets for Synchrony models are unlike any other. They are a blend of
two very different materials: aluminum and wood. Front and back
surfaces are from very solid double wall aluminum extrusions. The
strength and stiffness of aluminum allows a very rigid structure that can
be precisely machined to accept drivers and other components. Special
contours can be achieved in aluminum that preserve the sonic
characteristics of the drivers.
The curved side panels are made from multiple layers of wood. Wood is
stiff relative to its weight and has inherently high damping properties to
absorb sonic energy that might otherwise color the sound. The sides of
the Synchrony models are made from seven layers of 3mm MDF
individually laminated/formed onto a curved surface which improves the
panel's stiffness. Additionally, the sides are clad in finely finished
veneers to enhance the beauty of the systems.
DRIVERS
Drivers (woofers and tweeters) are a key component to the performance
of the new Synchrony models. A number of enhancements elevate them
over previous components.
Distortion Reduced Motor
The field generated by a signal driving the voice coil reacts with the field
in the magnetic structure's air gap. A long four layer voice coil normally
results in high self induction and impedance that varies with excursion.
