PSB Synchrony T600 Premium Tower Speaker - Gloss Black - Each

Three Woofers, Each in Its Own Isolated Chamber

The PSB Synchrony T600 is a 3-way floorstanding tower built around a 1-inch titanium dome tweeter, a 5.25-inch carbon fiber midrange driver, and three 6.5-inch carbon fiber woofers, each housed in its own individually tuned chamber.

PSB rates sensitivity at 89 dB anechoic (91 dB in a real listening room), and recommends amplifiers between 20 and 300 watts into a demanding 4-ohm load that rewards a genuinely capable amplifier.

The cabinet is available in Satin Walnut or High Gloss Black, and each tower is sold on its own, so a genuine stereo pair means ordering two speakers, one for each channel of a stereo system.

Where the Three Isolated Woofer Chambers Earn Their Keep

A Transitional 3-Way Design, Tri-Wire Ready

The 1-inch titanium dome tweeter, with ferrofluid damping and a neodymium magnet, crosses over to a dedicated 5.25-inch carbon fiber midrange driver at 1,800 Hz, the midrange mounted in a rigid die-cast aluminum basket.

Below 450 Hz, three 6.5-inch carbon fiber woofers take over in a transitional array, each covering a progressively narrower band and each isolated in its own tuned, rear-ported chamber to break up standing waves inside the cabinet.

The Numbers, and What They Ask of Your Amplifier

PSB quotes a frequency response of 24 Hz to 23 kHz at ±3dB. Sensitivity is 89 dB anechoic, though an independent bench measurement from Stereophile found it closer to 87 dB in practice. Nominal and minimum impedance are both 4 ohms, and PSB recommends amplifiers between 20 and 300 watts.

Three pairs of five-way gold-plated binding posts ship for tri-wire or tri-amp use. At just over 77 pounds each, plan for a firm, level floor to support this substantial tower.

What Reviewers Are Saying

Stereophile named the T600 a 2025 Recommended Component, saying it "stepped out of the way of the music being played, imposing almost no character on the sound other than a slightly mellow high treble and a slightly forward midrange."

Chris Eberle, Secrets of Home Theater and High Fidelity, called the T600 "quite simply, the best speakers I've ever heard in my home," adding that "no detail has been left unaddressed" in its design.

Who Is This Floorstanding Speaker Best For?

• You want a speaker Stereophile itself singled out — named a 2025 Recommended Component, recognition earned independently, not just marketing language
• You want three isolated woofer chambers, not a shared enclosure — each of the three woofers gets its own tuned chamber to break up standing waves
• You want a real choice of finishes — Satin Walnut or High Gloss Black, both furniture-grade
• Your amplifier has real current to spare — a 4-ohm load and a 20-to-300-watt recommended range reward a genuinely capable amplifier
• You want real floorstanding bass without a separate subwoofer — the T600 reaches to 24 Hz on its own. For the deepest home-theater effects, add one of our subwoofers and let the towers do what they do best

How Does It Connect to Your System?

Connect each tower to an amplifier or receiver's speaker outputs using the rear binding posts. A 4-ohm load calls for an amplifier genuinely comfortable driving a demanding impedance, ideally in the 20-to-300-watt recommended range.

Three pairs of binding posts accept a single-wire run with the factory jumpers in place, or a tri-wire/tri-amp connection with them removed.

Two included port plugs let you fine-tune bass output to suit your room, taming excess warmth near a wall without giving up low-end extension.

Pairs Well With

What finishes the system around a pair of Synchrony T600 towers:

• Stereo amplifiers — a separate power amp with real current is the natural match for this tower's 4-ohm load
• Integrated amplifiers — a high-current integrated amplifier rated well within the recommended range
• Speaker cables — premium cable for a tower Stereophile itself praised
• Audio racks — house the electronics driving an award-winning tower

Frequently Asked Questions

How much amplifier power do I need?

PSB recommends amplifiers between 20 and 300 watts. The 4-ohm nominal load calls for an amplifier genuinely comfortable driving a demanding impedance, not just one rated for the wattage.

Can I tri-wire the T600?

Yes. Three pairs of binding posts ship for single-wire use with the factory jumpers in place; remove them to tri-wire or tri-amp.

What finishes are available?

Satin Walnut or High Gloss Black, both furniture-grade real wood veneer.

What does the Recommended Component distinction mean?

It's Stereophile's own list of gear its editors independently vetted and found worth recommending — the T600 earned the honor for 2025.

Do I need a subwoofer with these speakers?

Not necessarily. The T600 reaches to 24 Hz on its own, though a subwoofer can still add reach for home theater use.
