Imagine W1 On-Wall Speaker

Ultra-slim, single-channel flat-panel speaker

It’s no secret that today’s ultra-thin flat-panel TVs are plagued by poor audio quality. To solve that problem, PSB created the Imagine W1. This super-slim on-wall speaker combines an extremely low profile with renowned PSB audiophile sound quality to provide a stylish and refined option whether used for front speakers or rear channels for your home theatre system.

  • 1″ (25mm) titanium-dome ferrofluid-cooled tweeter
  • Two 4″ (102mm) clay/ceramic reinforced polypropylene cone woofers
  • Two passive bass radiators

Use it as part of a customized home theatre solution

At a mere three inches (76mm) deep, the W1 hugs the wall, allowing for several creative mounting options while maintaining an immersive soundstage. The highly adaptable W1 can be used as a left, right, centre-channel, or surround speaker. Mount it vertically or horizontally on your wall using the included custom bracket, or place it on your entertainment center with the supplied tabletop stand.

Engineered for performance

The W1 utilizes a specially developed aluminium cabinet that provides a slim exterior while maximizing strength and internal volume. A non-resonant MDF baffle holds the drivers in carefully optimized positions for an ideal dispersion of sound. As with all PSB speakers, attention to detail is key—for example, soft rubber trim rings not only provide an attractive look but also control the dispersion of sound and further dampen unnecessary vibrations.

Specially developed drivers

The W1’s driver units were specially developed for its low profile using proven PSB technology. Two 4″ (102mm) long-throw woofers provide a natural and accurate vocal-range response as well as bass, while the 1″ (25mm) titanium-dome tweeter produces clear and delicate highs that accurately convey all of the detail in your favourite movies and music. Flanking the woofers are two passive bass radiators, which provide the W1 with stronger bass performance than you might expect from a slim, on-wall speaker.

 Rich sound meets stylish good looks

All of the W1’s drivers are optimally mounted in a non-resonant MDF baffle for ideal sound dispersion, and they are concealed behind an acoustically transparent, cloth-covered metal grille for stylish good looks. Any way you choose to incorporate this handsome speaker into your system—whether it’s mounted on the wall or placed on your entertainment centre—it will certainly look at home.
