Why Choose PSB

PSB Speakers is a Canadian loudspeaker manufacturer founded by legendary designer Paul Barton, whose work has long focused on combining scientific acoustic research with natural and highly approachable musical performance. Developed alongside extensive listening research conducted through Canada’s National Research Council, PSB products are engineered around the idea that loudspeakers should reproduce music with tonal accuracy, balance, and long-term listenability across real-world listening environments.

At HeyNow Hi-Fi, PSB occupies a particularly interesting space within the market because the range combines excellent engineering, practical usability, and strong value while remaining less commonly encountered than many mainstream loudspeaker brands. The result is a lineup that often surprises customers with just how refined, flexible, and musically satisfying the products are at their respective price points.

Signature Design and Sound

PSB products are known for their balanced and easy-to-live-with presentation. Rather than sounding exaggerated or overly analytical, the speakers tend to focus on tonal coherence, natural vocals, controlled bass performance, and broad compatibility across different amplifiers, rooms, and listening styles.

One of the standout areas within the range is the PSB Alpha iQ active streaming speaker system. Incorporating integrated amplification together with the excellent BluOS streaming platform, the Alpha iQ delivers a highly modern and remarkably complete Hi-Fi solution with minimal system complexity. For customers wanting genuine stereo performance without the need for multiple separate components, the Alpha iQ has become one of the most compelling compact streaming systems currently available.

PSB’s AM Series active speakers also offer a highly practical and musically engaging approach to modern desktop and compact Hi-Fi listening. Combining active amplification with strong tonal balance and excellent usability, they work beautifully within home offices, smaller rooms, and lifestyle-oriented listening spaces while still maintaining genuine stereo credibility.

The range also extends into architectural speakers, including in-wall and in-ceiling models designed for discreet distributed audio and home theatre integration, together with heritage-inspired passive speakers such as the Passif 50, which offers a modern interpretation of classic monitor-style loudspeaker design.

PSB Product Range

The PSB range available through HeyNow Hi-Fi includes active streaming loudspeakers, powered desktop speakers, passive loudspeakers, architectural audio solutions, and wireless headphone products designed for both home and travel use.

The Alpha iQ and AM Series in particular represent excellent opportunities for customers seeking high-quality sound with minimal complexity, while the Passif 50 appeals strongly to listeners who appreciate classic loudspeaker proportions and a more traditional stereo presentation.

PSB’s wireless noise-cancelling headphones also remain highly practical for travel, particularly due to their use of replaceable AA battery operation rather than fixed internal rechargeable batteries. For many travellers and long-term owners, this offers a level of convenience and longevity that is becoming increasingly rare within modern portable audio products.

At HeyNow Hi-Fi, Geoff and his experienced system setup team provide assistance with streaming integration, speaker matching, architectural audio planning, and complete system optimisation to ensure PSB products perform at their full potential within each customer’s listening environment.
