Our take on the PSB Synchrony Two B by Crutchfield's Kristen Schaub
Exceptional performance from compact bookshelf speakers
PSB's Synchrony Two B delivers sound so natural and rich, you'll be surprised to hear it coming from a bookshelf speaker. Your eyes will appreciate this speaker's simple, sophisticated looks, and your ears will appreciate PSB's precise driver design. This bookshelf pair works great on its own, or you can add one of PSB's HD subwoofers to create a high-performance stereo music system that's worthy of everything from classical to rock.
"The Synchrony Two B impressed me as an unflappable performer with tonal qualities remarkably similar to the Synchrony One flagship. The superb construction quality, details, and fittings are also identical. The amazing thing about this speaker (Synchrony Two B) is that except for the lack of deep bass, it sonically mirrors the Synchrony One flagship. PSB hasn't just paid a lot of lip service to the subject of timbre matching; they've achieved it."
Neil Gader, The Absolute Sound, December 2007
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.
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
The Synchrony Two 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.

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 crossover is a 2-way acoustical fourth order Linkwitz-Riley type with a 24 dB/octave slope. Tight tolerances were used when choosing the crossover components; heavy multi-laminated iron cores are used for large value inductors, high gauge wire air core inductors are used for medium and small values, all the capacitors are low loss and film capacitors are used for the midrange and treble frequencies.
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 Two 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.
Dual Binding Posts: 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 Two 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.
