PSB Synchrony B600 Premium Bookshelf Speaker (Pair) at Vinyl Sound Toronto Canada

The Synchrony B600 is a 2-way stand-mount bookshelf speaker from PSB Speakers (Pickering, Ontario, Canada), available as a pair at Vinyl Sound in Toronto, Canada. The flagship bookshelf model in PSB's premium Synchrony Series, the B600 was designed at the world-renowned acoustics laboratories of Canada's National Research Council (NRC) in Ottawa by Paul Barton and his engineering team using scanning laser vibrometer analysis, finite-element modeling, and precision anechoic chamber measurement. It features a 6.5" woven carbon fiber woofer with cast aluminum basket and mass-loaded rubber surround, a 1" titanium dome tweeter with Ferrofluid damping and neodymium magnet, a 5mm-thick solid anodized aluminum front baffle, and four integrated IsoAcoustics isolation feet derived from IsoAcoustics' award-winning Gaia II isolator design. Rated frequency response is 50Hz to 20,000Hz (+/-3dB) with 86dB anechoic sensitivity and 6 ohm nominal impedance. The SoundStage! Hi-Fi Recommended Reference Component-designated B600 is available in Satin Walnut Veneer and High Gloss Black finishes.

Advanced Driver Platform and Amplitude-Perfect Crossover

The PSB Synchrony B600's driver complement shares its technology platform with the flagship Synchrony T600 tower speaker. The 6.5" woofer is built around a woven carbon fiber cone that combines low mass with high stiffness, resisting cone breakup distortion through the upper bass and into the lower midrange without the additional weight that would limit transient speed. A mass-loaded rubber surround suppresses standing wave reflections within the cone, reducing harmonic distortion that would otherwise arise from reflected energy traveling back toward the voice coil. The motor structure is engineered to maintain constant magnetic force throughout the full excursion range of the voice coil, ensuring linear excursion at high output levels and minimizing intermodulation distortion under dynamic program material. The 1" titanium dome tweeter uses Ferrofluid in the voice coil gap for both thermal management and mechanical damping, contributing to consistent high-frequency output without compression during sustained high-level listening. The drivers are connected via an amplitude-perfect fourth-order Linkwitz-Riley acoustic crossover at 2,200Hz, a topology that achieves flat summed amplitude response at the crossover frequency with minimal phase error and coherent time-domain behavior. A PSB design hallmark, the woofer is positioned above the tweeter on the baffle, placing the acoustic center of the speaker approximately 12" up from the bottom edge of the cabinet, which optimizes phase alignment across seated and standing listening positions.

Aluminum-Clad Cabinet, IsoAcoustics Integration, and Vibration Control

The B600 enclosure is constructed from extensively braced MDF, with the internal bracing pattern calculated to push cabinet panel resonances well above the speaker's operating bandwidth and reduce their amplitude. The front baffle is fully clad in a 5mm-thick solid anodized aluminum plate, a treatment PSB describes as eliminating "baffle talk," the tendency of a conventional MDF baffle to vibrate sympathetically with driver output and add a diffuse low-level coloration that obscures micro-detail and softens transient leading edges. A matching smaller aluminum panel surrounds the rear-firing port, whose flange is CNC-turned from solid aluminum for precise port geometry and visual continuity with the front baffle. At the base of the enclosure, four IsoAcoustics isolation feet custom-designed for PSB adhere to the supporting surface and decouple the cabinet from vibration reflected back from the stand or shelf, reducing the re-excitation of the enclosure from below. PSB's partnership with IsoAcoustics for the Synchrony Series represents the first integration of dedicated acoustic isolation feet at the manufacturing level in a PSB production loudspeaker.

Frequently Asked Questions

What is the PSB Synchrony B600?

The PSB Synchrony B600 is a 2-way stand-mount bookshelf speaker and the flagship bookshelf model in PSB's premium Synchrony Series, designed by Paul Barton at Canada's National Research Council facilities in Ottawa. It features a 6.5" woven carbon fiber woofer with cast aluminum basket and mass-loaded rubber surround, a 1" titanium dome tweeter with Ferrofluid damping, a 5mm solid anodized aluminum front baffle, and four integrated IsoAcoustics isolation feet based on the award-winning Gaia II design. Its rated frequency response is 50Hz to 20,000Hz (+/-3dB), with 86dB anechoic sensitivity and 6 ohm nominal impedance. The B600 earned the SoundStage! Hi-Fi Recommended Reference Component designation in 2021 and shares its driver platform with the Synchrony T600 flagship tower speaker.

How does the PSB Synchrony B600 compare to the Revel M126Be or KEF LS50 Meta?

The PSB Synchrony B600, Revel M126Be, and KEF LS50 Meta each represent distinct engineering approaches to premium stand-mount speaker design. The Revel M126Be uses an aluminum cone woofer and beryllium dome tweeter, with stronger off-axis uniformity at higher frequencies. The KEF LS50 Meta employs a coaxial point-source driver configuration for a different stereo imaging characteristic. The PSB B600 differentiates itself through its woven carbon fiber woofer, mass-loaded rubber surround, IsoAcoustics integration at the manufacturing level, and its NRC-voiced fourth-order Linkwitz-Riley crossover, which published reviewers note produces bass output and dynamic headroom that significantly exceed what the B600's cabinet size would suggest. In direct comparison at SoundStage! Hi-Fi, the B600 was found competitive with the Revel M126Be despite the Revel's higher price point.

What does the IsoAcoustics integration do for the Synchrony B600?

The four IsoAcoustics isolation feet built into the base of the PSB Synchrony B600 are custom-designed derivatives of IsoAcoustics' award-winning Gaia II isolators, adhered to the underside of the enclosure. They function by mechanically decoupling the speaker cabinet from the surface it rests on, preventing two forms of vibration transfer: energy from the drivers and cabinet radiating downward into the stand or shelf and being reflected back upward into the enclosure, and structure-borne vibrations from the floor or stand traveling into the cabinet. By suppressing both pathways, the IsoAcoustics feet improve micro-detail resolution, sharpen transient leading edges, widen the perceived soundstage, and increase imaging precision. PSB's dedicated Synchrony 24" stands are designed to accept the B600's IsoAcoustics feet directly, maintaining the full decoupling system from speaker to floor.

What amplifier does the PSB Synchrony B600 pair well with?

The PSB Synchrony B600 is rated for amplifiers delivering 15 to 150 watts into its 6 ohm nominal impedance, with a 4 ohm minimum that places moderate current demands on the amplifier. Published reviews confirm that the B600 rewards amplifiers with strong current delivery: reviewer accounts note that the speaker opens up significantly with amplifiers rated at 80 watts per channel or above into 4 ohms, with mid-tier to premium integrated amplifiers from NAD Electronics, Arcam, Cambridge Audio, Rotel, and McIntosh Laboratory all cited in published reviews as strong matches. For the B600's bass capability to be fully realized, an amplifier comfortable into low impedance loads is more important than raw watt ratings alone. AV receivers with 6 ohm ratings and high-current output stages are also viable for home theatre use.

Can the PSB Synchrony B600 be used without a subwoofer?

Yes, the PSB Synchrony B600 is capable of full-range use in small to medium-sized rooms without a subwoofer for most music content. Its 6.5" woven carbon fiber woofer in a tuned rear-porting bass-reflex enclosure extends bass to a rated 50Hz (+/-3dB) and a -10dB point of 35Hz, an unusually deep low-frequency extension for a speaker of its cabinet volume. Reviewers have consistently noted that the B600 produces bass output well beyond what its size suggests, making it suitable for acoustic music, jazz, and orchestral content without sub support. For home theatre applications where low-frequency effects below 40Hz are common, adding a dedicated subwoofer and crossing the B600 over at 80Hz via the AV receiver's bass management is recommended to maximize both deep bass reproduction and the B600's dynamic headroom on program content.

What stands should I use with the PSB Synchrony B600?

PSB offers dedicated Synchrony 24" speaker stands designed specifically to interface with the B600's integrated IsoAcoustics isolation feet. The stand's top plate is sized and positioned to accept the four IsoAcoustics footers directly, preserving the full mechanical decoupling system from the speaker through the stand to the floor. Height-adjustable floor spikes provide a stable and level footing on both carpeted and hard surfaces. While third-party stands can also support the B600, using stands not designed for the IsoAcoustics footer spacing may interrupt the decoupling system and reduce the isolation benefit. For listeners placing the B600 on an existing shelf or equipment rack, the integrated IsoAcoustics feet still function independently of stand choice.
