PSB Synchrony Two B: A bookshelf model with remarkable range and presence

The PSB Synchrony Two B bookshelf monitor uses the same tweeter and woofer of the Synchrony Two tower for superior sound quality no matter what the source.

1-inch titanium dome tweeter with neodymium magnets
5-1/4-inch fine-weave fiberglass woofer
Hand-selected real wood veneer finish
Two sets of gold-plated five-way binding posts for bi-wiring

“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 The PSB Synchrony Two B is two-way bookshelf speaker equipped with the Synchrony high-linearity titanium-dome tweeter and a 5-1/4-inch, dual-laminate-weave woofer. It works well with a high-performance subwoofer such as PSB’s own ultra-compact HD models, yet with output down to a remarkable 50 Hz, it’s fully capable of serious music reproduction on its own. Though more compact — and more affordable! — than the Synchrony tower models, the Two B is remarkably close in sound to its larger floorstanding brethren.

Synchrony acoustical modeling minimizes the negative synergy of typical speaker placements and room acoustics. Synchrony’s “tweeter-under” driver-array is computer-derived to spread the listening “sweet-spot” over seated-to-standing height, so everyone in the room gets to hear great sound! And every Synchrony model presents a stable, easy-to-drive electrical “load” that allows amplifiers to operate at peak performance.

PSB is known internationally as the leader when it comes to loudspeakers of world-standard performance and value. PSB’s credentials — over 35 years of experience in loudspeaker design, led by musician-engineer Paul Barton, exploiting the unmatched acoustical facilities of the Canadian National Research Council in both pure research and product development — are well established.

Synchrony carries these traditional PSB virtues to new heights, with seven models developed together and tonally matched to unprecedented precision. In doing so Synchrony yields sonic performance that pushes the boundaries of the possible, whether judged by way of close technical analysis or by rigorous subjective evaluation. Yet Synchrony delivers something more: a measure of visual elegance and luxurious finish unprecedented in such thoroughly engineered, advanced-performance loudspeakers. As a result, the seven elegant, small-footprint Synchrony models integrate quietly into today’s most sophisticated listening rooms and home theaters.

Tweeter
The titanium Synchrony tweeter, an evolution of PSB’s famous 25mm metal-dome design, incorporates more than a score of new features engineered to extend high-output, distortion-free response while banishing the dynamic compression that limits most designs. This is achieved by a lighter, stiffer, and Ferrofluid-cooled voice-coil, along with a computer-optimised magnetic circuit using a high-flux neodymium magnet to maintain perfect linearity under even the highest power drive.

Woofer
The Synchrony woofers and midranges bristle with advancements. Laminated cones sandwich fine-weave fiberglass and compressed-felted fibers into a uniquely rigid, self-damping, low-mass diaphragm for higher sensitivity and smoothness. Oversized voice coils, and distortion-arresting motor structures preserve magnetic linearity at even extreme excursions, for clarity, detail, and “drive.” Carefully engineered ventilated spiders, and rubber surrounds contribute both error-free dynamics and longevity. The cast aluminum Synchrony baskets are superbly rigid, aerodynamically “open,” and magnetically inert, resulting in maximum efficiency of the motor/magnet structure.

Fourth-order crossover for the best 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."

Superior cabinet construction reduces resonance
PSB’s unique construction details help make the Synchrony family one of the strongest, most inert, resonance-free enclosures in the industry. Extruded aluminum front and back panels unite subtly curving, seven-layered, hand veneered sides into an unbelievably robust structure. Their unbroken, diffraction-free surfaces and near total resistance to coloration-carrying vibrations yield arresting sonic purity — and smooth, beautiful surfaces utterly devoid of visually intrusive hardware.

Double-locking aluminum corners bind each Synchrony enclosure with incredible solidity and “float” its elegant perforated aluminum grille — a uniquely open pattern that’s genuinely acoustically transparent. The double-layer aluminum front baffle sandwiches an elastometric layer that damps unwanted vibrations, fixing the drivers in an utterly rigid, inert working surface.

Terminal cup
Even Synchrony’s solid-metal speaker connectors have been specially designed: gold-plated for maximum conductivity; accepting banana plugs, pins, spade-lugs, or wire up to 10 gauge; equipped with unique, ergonomically designed easily grasped tightening “wings”; and of course configured with discrete woofer/tweeter terminals for easy bi-wiring/bi-amping.
