PSB, the legendary Canadian speaker manufacturer, has just announced the return of its flagship Synchrony series with two new models: the T600 tower and B600 bookshelf, as the company celebrates its 50th anniversary next year. “Evolution” and “refinement” are the watchwords for the latest speakers, according to founder and chief designer Paul Barton during an online press conference.

The Synchrony T600 towers from PSB Speakers are the best example of the brand’s “True to Nature” design philosophy since its inception in 1972. This latest flagship tower, designed and engineered in Canada by a team of highly regarded acoustic specialists led by renowned PSB Founder and Chief Acoustic Designer, Paul Barton, features a new 5-way transitional driver array, 4-chamber cabinet, and custom IsoAcoustic isolators to provide an immersive, tonally accurate listening experience.

T600

The T600 is a “transitional 3-way” design, with a 1-inch titanium-dome tweeter mounted below a 5.25-inch carbon-fiber cone midrange, both positioned above three 6.5-inch carbon-fiber cone woofers that join forces at low frequencies and gradually drop out one by one as the frequency rises. Every woofer has its own bass-reflex chamber, which has rear-facing ports and is about the same size. It has an on-axis frequency response of 30Hz to 20kHz (1.5 dB) and 24Hz to 23kHz (2.5 dB), a sensitivity of 91dB in a listening room, a nominal and minimum impedance of 4 ohms, and a recommended power rating of 20 to 300 watts.

The PSB Synchrony T600 features a brand-new 5-way transitional array capable of providing unrivaled tonal, spatial, and dynamic precision to the most technically refined and challenging music and film recordings. The new driver platform, which includes three 6.5” woofers and a 5.25” midrange driver with cast aluminum baskets, woven carbon fiber cones, and rubber surrounds, as well as a 1” titanium dome tweeter with Ferrofluid and Neodymium magnet, reduces non-linear distortion dramatically, allowing for higher sound pressure levels without compression or increased THD and IM distortion.

The B600, on the other hand, is a 2-way configuration with the same 1-inch titanium-dome tweeter mounted underneath one 6.5-inch carbon-fiber woofer in its own rear-ported chamber to achieve a frequency response of 55Hz to 20kHz (1.5 dB) and 50Hz to 33kHz (3.5 dB). In a listening area, the sensitivity is 88dB, the nominal impedance is 6 ohms (minimum 4 ohms), and the recommended power rating is 15 to 150 watts.

PSB has introduced woven carbon-fiber midrange and woofers, which have low mass and high stiffness. In addition, the woofer’s new magnet design incorporates ceramic and neodymium magnets, as well as an aluminum Faraday ring, which is said to minimize odd and even harmonic distortion significantly. The tweeter is based on the Imagine series’ tweeter, but with a new phase plug that improves dispersion and control of the breakup modes.

Both models have a 5mm black anodized aluminum baffle that is sealed to the cabinet with “iso cups,” shock absorbers that decouple the baffle and drivers from the cabinet, effectively preventing vibration transfer. These speakers also feature more cabinet bracing than previous versions, as well as IsoAcoustics’ unique isolation feet, which offer a high level of decoupling from the surface on which they rest while avoiding lateral movement and oscillations.

The T600 and B600 will be available in a satin walnut veneer or a high-gloss piano black finish in June 2021. The T600 will cost $7,999 per pair, while the B600 will cost $2,499 per pair (either finish).
