About the PSB Synchrony One B
Capable bookshelf speakers for the stereo music enthusiast
PSB's Synchrony One B produces remarkably natural sound that's similar to the line's impressive floor-standing speakers. Your eyes will appreciate its simple, sophisticated looks, and your ears will appreciate PSB's precise driver design. This speaker's compact bookshelf design and outstanding performance make it a great fit for dedicated two-channel music systems.
PSB's Synchrony speaker family (Synchrony One B shown on stand)
Great sound begins with quality driver materials
The 1" titanium dome tweeter is carefully crafted to produce smooth, accurate highs free from distortion and grain. The woofer cone is made of fine-weave fiberglass, which creates a stiff, self-damping cone. You'll hear exceptionally clean mids with excellent detail and tonal accuracy, plus surprisingly deep bass for a speaker this size. Extra-large voice coils and virtually distortion-free motor structures help preserve clarity and detail. Plus the rigid, cast aluminum baskets are magnetically inert for maximum efficiency.
The woofer uses a lightweight, rigid fine-weave fiberglass cone for exceptionally smooth response.
The tweeter uses a high-flux neodymium magnet to maintain clear, accurate highs, even during dynamic peaks like explosions or cymbal crashes.
Top-notch crossover ensures optimal sound dispersion
PSB's years of design experience and tireless testing at the National Research Council in Canada have led to a superior crossover design. The high-quality components are carefully picked to create the fourth-order crossovers that go into Synchrony speakers. Meticulous engineering ensures minimal driver overlap, with precisely chosen crossover points to maintain proper dispersion. The result is a smooth frequency response over a wide "sweet-spot."
A solid cabinet with a luxurious, real-wood veneer finish
Extruded aluminum front and back panels hold the curved, seven-layered side panels in place, creating an incredibly rigid, acoustically inert cabinet.
The Synchrony One B's heavy, rigid cabinet helps eliminate vibrations to maintain tonal accuracy. The double-walled aluminum front and back cabinet surfaces hold the curved side panels in place. Each side panel is constructed using seven layers of MDF, each one individually laminated to improve the panel's stiffness and absorb sonic energy that might otherwise color the sound. The top and side panels are clad in real wood veneer that's hand selected for its beauty and quality.

Driver Technology
Cone Design: The woofer cones are a laminated sandwich design; each has a fine weave fiberglass layer along with a compressed, felted natural fiber laminate. The result is a rigid cone with added damping properties. The central dustcap offers a second connection to the voice coil to improve bass and midrange control. The inherent distortion resulting from the magnetic field generated by the input signal reacting with the field in the magnetic structure's air gap and the self-induction and impedance that varies with cone movement are addressed using an aluminum shorting ring within the magnet structure, an aluminum phase plug on the pole piece, and a shorted copper turn on top of the pole piece. The aluminum phase plug also mechanically smoothes the response and acts as a heat sink for the voice coil, reducing power compression. The drivers use cast aluminum baskets and rubber surrounds.
Tweeter: The 1" titanium, Ferrofluid cooled dome tweeter has a neodymium motor structure and an aluminum heat sink. The mass (low) and stiffness (high) are optimized for the required wide frequency response.
Crossover Network: The dual binding post input terminals are located on the rear panel of the speaker cabinet. The two sets of binding posts are shorted together by a gold-plated jumper. With the jumper removed the Synchrony One B can be bi-wired or bi-amplified. The binding posts will accept spade connectors, single banana plugs, pin connectors, and bare wire up to 8 gauge.
Enclosure Design
Cabinet: The cabinet is an integral part of speaker design and has a dramatic effect on the overall sound of a speaker. PSB uses a combination of aluminum and wood in the Synchrony One B's construction. The front baffle and rear panel are made of double wall aluminum extrusions. The aluminum panels are very rigid and precisely machined with contours to preserve the sonic characteristics of the drivers. The side panels are seven layers of 3mm MDF, curved for added stiffness, with a wood veneer exterior. While rigid, MDF also has inherent damping properties to absorb energy that might otherwise color the music.
Connections
Dual Binding Posts: The dual binding post input terminals are located on the lower rear of the speaker cabinet. The two sets of binding posts are shorted together by a gold-plated jumper. With the jumper removed the Imagine B can be bi-wired or bi-amplified. The binding posts will accept spade connectors, single banana plugs, pin connectors, and bare wire up to 8 gauge.
