PSB Positions 7-SKU Synchrony as its New Flagship Line
Lenbrook’s PSB Speakers brand is taking the occasion of the Fall CEDIA Expo to give full demonstrations of its new, seven-model flagship loudspeaker line, the Synchrony Series. It consists of two towers, two bookshelf models, two center-channel models and a “tri-mode” surround speaker, and ranges downward in price from the Synchrony One’s $4,500-per-pair ticket.
Paul Barton, PSB’s founder and design-team leader, says the line, in development for more than two years, represents its newest “statement” design. “With Synchrony, our design approach has been taken another step,” Barton says. One manifestation of this new approach is that on the Synchrony range, the entire baffle and back are made with heavy-gauge aluminum extrusions. The speakers’ sides are of seven eighth-inch-thick MDF layers laminated onto a curved surface and fused with a glue that is activated by radio frequencies – the first time the company has used this construction technique, he says. “There are no clamps in the cabinet; its design is based on high-tolerance machining,” he adds. Special attention has also been paid to the grille system, Barton says: “It has no influence on the sound – it’s acoustically transparent because it is so close to the driver there is no effect on the tweeter.”
The five-driver, top-line Synchrony One tower is designed with three individually ported, separately tuned chambers that house its three woofers; its midrange also has its own cavity. Tweeters are extended-response, of low-mass titanium, and their lower-than-usual placement is particularly striking on the One B bookshelf model. The “tweeter-under” placement is justified, says, Barton, so that “in-phase lobe” is even, whether the listener is seated or standing.
