Engineering such a high level of performance from a slim profile speaker is a serious challenge, but thanks to PSB's 40 years of experience and deep working knowledge of acoustics, the Imagine W3 succeeds. Like all PSB speakers, final voicing for the Imagine W3 was conducted at the scientific facilities of Canada's famed National Research Council. Research and testing has revealed how listener preferences can be integrated into the W3's speaker design for this specific application, yet still uphold PSB's true-to-nature sound.
A special aluminium cabinet minimizes external bulk and maximizes strength and internal volume in order to gain maximum internal volume, which is necessary for good sound and deep bass response. A non-resonant MDF baffle mounts the driver units in carefully optimized positions for an ideal dispersion of sound to the listener. Soft rubber trim rings provide a sleek look while controlling dispersion of sound and adding further damping of spurious vibrations. The metal grille is covered with an attractive cloth, which is transparent to sound and makes the Imagine W3 easy to incorporate with your home décor.
The driver units were specially developed for the low profile Imagine W3 using proven PSB technology. The tweeters use the same titanium dome first seen in PSB's award-winning Synchrony Series, and feature a specially engineered "phase plug" or shield that extends the high frequency response by dampening the tweeter's resonance and preventing phase cancellation in the top musical octave. The clear delicate sounds achieved by this remarkable tweeter accurately reproduce all the musical detail contained in your favourite movies and music. The woofers are no less sophisticated, combining a long throw for good bass response, with an ideal cone profile to assure the accurate natural vocal range response especially important for movies and television. Bass is enhanced by specialized speakers called PBRs that extend the bass reach by doubling the output of the woofers at the lowest frequencies.
One of the most critical aspects of speaker is the crossover network; this is where the final voicing and integration of all the elements of the design are determined. Even proximity to the wall behind has an effect that must be considered when fine tuning the crossover. High quality close tolerance parts make sure that every speaker produced accurately meets its rigorous specification.
