No-Compromise Tri-Mode Surround Speaker
For surround sound performance that will impress the fussiest home theater aficionado, the PSB Synchrony S is a dedicated "tri-mode" speaker consisting of two dual two-way arrays.
This tri-mode design may be operated as a dipole-surround, as preferred by many home-theater designers for movie-centered systems, as a monopole reproducer for multi-channel music playback where the most rigorous matching of timbre and directionality is demanded, or in bipolar mode (all four drivers operating and in-phase) for maximum coverage, dispersion, and output.
"It Will Pull at Your Ears and Heartstrings"
The January 2008 issue of The Perfect Vision magazine gave a Synchrony Two-based speaker system its "2007 Editor's Choice Award" for "Best High Performance Home Theater Speaker System."
According to The Perfect Vision, This is not a system you can (or should) listen to in a casual way, because it will continually pull at your ears and heartstrings -- almost forcing you to care about musical performances."
"My Speakers for the Next Decade or Two"
Sound & Vision magazine bestowed its "2007 Editors' Choice Audio Product of the Year" on the PSB Synchrony series. According to Daniel Kumin, "Here are my speakers for the next decade or two."
"According to my value system for loudspeakers -- honest octave-to-octave balance, precise imaging, expansive spatial accuracy, freedom from dynamic compression, and absence of coloration -- PSB's Synchronys are among the best loudspeakers I've auditioned in my studio in several years," reports Al Griffin in the November 2007 issue of Sound & Vision magazine. "You could easily spend substantially more and do no better, or not as well. Synchrony was definitely worth the wait."
"The Synchrony models are clearly Barton's best ever design," reports Steve Guttenberg in the August 8, 2007 edition of his Audiophiliac CNET blog. "The sound… was spectacularly vivid."
"Low Frequency Extension"
"Driver coherence was excellent," notes Neil Gader in his preliminary encounter with the Synchrony series in the October 2007 issue of The Absolute Sound magazine. "Naturally, the S1 tower held the advantage in dynamic headroom and low frequency extension, but the midrange 'voice' of these speakers was nearly indistinguishable… Port and cabinet colorations were vanishingly low… "
The Synchrony S drivers consist of dual 5.25" fine weave fiberglas, natural fiber cone sandwich woofers with rubber surround, and dual 1" titanium dome tweeters with ferrofluid cooling.
From-the-Ground-Up Technology
The Synchrony drivers, enclosures, and crossover circuits are all ground-up components, but in every case are important evolutions of longstanding PSB technologies. The Synchrony structures reflect continued development of PSB's unique, proprietary cabinet-construction system, employing extruded-aluminum corners and tapered rear panels, in combination with elegantly veneered, seven-laminate wood-composite curved side panels, to form what is possibly the strongest, "deadest," most non-resonant and coloration-free enclosures in the industry.
Synchrony continues PSB's tradition of extended-response titanium-dome tweeters, in a new generation that extracts even greater high-output linearity thanks to multiple technical enhancements in its neodymium magnet structure, lighter, stiffer voice-coil components, and enhanced mechanical systems.
Equivalent developments in the 6.5-inch and 5.25-inch cone woofers employed throughout the line (and the Synchrony One's 4-inch midrange as well) have concentrated on improving linearity and virtually eliminating dynamic compression.
In addition to their distortion-arresting electro-magnetic elements (aluminum bullet, copper "shorted-turn," and aluminum magnetic focusing ring), the Synchrony cone drivers all employ a newly developed sandwich-laminate diaphragm material composited from woven fiberglass and compressed felted-complex natural materials, as well as ultra-rigid, cast-aluminum baskets. The sum of these parts is fast-reacting, pure reproduction that contributes impressively lifelike transients and an unprecedented degree of clean, high-output bass.
Uncanny Crossover Performance
PSB's care in crossover design and driver-circuit electro-acoustic integration, already widely admired, has been even further developed for the Synchrony line. All models employ fourth-order acoustic Linkwitz-Reilly sections, for the best possible unification of drivers into a single acoustic entity, with minimal errors in both the amplitude (frequency-response) and time (phase-response) domains, and insignificant static and dynamic distortions. Consequently, the Synchronys' ability to conjure up depth, imaging precision, and spatiality from both two-channel and multichannel productions, is nothing short of uncanny.
Superb performers on their own merits, PSB's latest flagship designs are equally unique in the degree to which work to answer the real-world problems of integrating the loudspeaker with the reproduction system and the listening room. All of the Synchrony models are engineered to produce stable, overwhelmingly resistive (and thus easy-to-drive) loads over their full high-power operating ranges: in short, they make amplifiers work better and sound better.
Each Synchrony is designed so that its "in-phase lobe" is balanced and even throughout the seated-to-standing vertical window of the prime listening area (hence their "tweeter-under" layouts), ensuring their superb sound under real-life listening conditions.
Timbre-Matched System
The entire Synchrony line is extraordinarily superbly matched in timbre -- a claim often made but rarely supported -- so that any selection of floor, stand, and multichannel models may combine to form a tonally cohesive surround system. |
