PSB Imagine T65 black (pack of 2)

The PSB Imagine T65 represent an evolution in the Canadian manufacturer’s lineup. These three-way floorstanders combine technologies drawn from the Synchrony series with pricing aimed at a broader audience. Developed in collaboration with the National Research Council of Canada, they apply Paul Barton’s “True to Nature” philosophy, in a format designed to blend into contemporary interiors.

Sophisticated acoustic design in the service of musicality

The PSB Imagine T65 use a three-way configuration with four drivers, each optimized for its specific frequency range. The 25 mm titanium-dome tweeter benefits from an especially powerful neodymium magnet, a technology taken directly from the Synchrony series. Ferrofluid cooling enables optimal heat dissipation, ensuring treble reproduction that is both detailed and free of harshness, even during extended listening sessions. This technical approach extends response up to 23 kHz while maintaining remarkable linearity through the critical crossover region.

The 133 mm midrange driver occupies a strategic position at the top of the tower, following a well-established PSB tradition. Its woven carbon-fiber cone—material Paul Barton had already successfully explored with the Platinum series two decades ago—offers an optimal stiffness-to-mass ratio. Housed in its own hermetically sealed enclosure, this driver reproduces the crucial 200 Hz to 2000 Hz region with surgical precision. This range contains most of the information related to instrumental and vocal timbre and pitch, explaining why PSB gives it such particular attention.

The two 165 mm woofers share the same woven carbon-fiber cone technology but each benefits from its own meticulously tuned acoustic chamber. This approach, unusual at this price point, enables optimal control of each driver’s behavior while minimizing parasitic interactions. Natural rubber surrounds ensure generous, linear excursion, allowing low-frequency extension down to 28 Hz at -3 dB—a remarkable performance for drivers of this diameter.

Laminar ports innovation: a distinctive technical signature

The PSB Imagine T65 stand out with their rear dual laminar bass-reflex ports, a feature borrowed from the PWM (Performance Wall Mount) series. Unlike traditional circular ports, these rectangular slot openings offer several acoustic advantages. Strategically positioned—one near the bottom and the other about 40 cm higher—they provide better distribution of the acoustic load while reducing air turbulence at high levels.

Each port is individually tuned to its respective woofer chamber, effectively creating two independent bass-reflex systems within the same cabinet. This design allows separate optimization of each woofer’s behavior, resulting in bass that is both deep and articulate. The absence of port noise, even at high power, attests to the effectiveness of this technical solution.

Fourth-order Linkwitz-Riley filtering: a PSB hallmark

The crossover network is one of the T65’s most sophisticated elements. True to Paul Barton’s philosophy, it employs a fourth-order Linkwitz-Riley topology with crossover points at 600 Hz and 2000 Hz. This approach, consistent across nearly all PSB designs, blends the discrete drivers into a coherent acoustic entity with minimal impact in both the amplitude (frequency response) and time (phase response) domains.

The crossover leverages the natural roll-off points of each driver, minimizing the need for corrective measures and preserving signal dynamics. Carefully selected components and thoughtful circuit layout maximize signal transfer while keeping static and dynamic distortions well below perceptible thresholds. This technical approach yields exemplary tonal coherence across the entire audible spectrum.

Construction and finish: balancing performance and accessibility

The T65’s MDF cabinet, measuring 213 × 986 × 343 mm and weighing 20 kg per speaker, benefits from extensive internal bracing. This structure ensures high inertia and minimizes unwanted resonances—essential for faithful reproduction. Separate chambers for each woofer reflect particular attention to internal acoustic isolation.

The satin black or satin white finishes, while understated, integrate harmoniously into any listening environment. Aluminum trim rings around each driver add a touch of modernity while visually reinforcing the build quality. The cabinet’s chamfered edges are not merely decorative: they help reduce edge diffraction at the baffle.

The aluminum foot system with decoupling spikes, supplied with spike pads to protect delicate floors, ensures optimal mechanical stability. The gold-plated dual binding posts accept bi-wiring or bi-amping, giving users the flexibility to optimize their system to taste. The supplied gold-plated jumpers maintain optimal connection quality in single-wiring configuration.

Acoustic performance: the synthesis of precision and musicality

With a sensitivity of 88 dB in an anechoic chamber (90 dB in real-world conditions) and a nominal impedance of 8 ohms dipping to a minimum of 4 ohms, the T65 are relatively easy to drive. PSB recommends amplification between 20 and 200 watts, with the primary criterion being the amplifier’s ability to comfortably handle the 4-ohm impedance dip.

The frequency response curve demonstrates remarkable technical control: 37–20,000 Hz at ±1.5 dB on-axis, maintaining linearity of 37–10,000 Hz at ±1.5 dB off-axis at 30°. This consistent off-axis response ensures a stable stereo image and a wide listening area, especially valuable in home theater setups as well as in pure stereo listening.
