PSB, long renowned for affordable excellence in loudspeaker design, launched an all-new range of Alpha loudspeakers that, like their predecessors, deliver remarkable value and performance. It appears that by popular demand, Paul Barton tries to redefine the performance/value equation. Four models in all, the new Alpha Series is comprised of compact monitors P3 ($199 per pair) and P5 ($349 per pair), a center channel C10 ($299 each) and a tower model T20 ($599 per pair). Additionally, all four models are available in a choice of Walnut or Black Ash finishes.
PSB introduced its first Alpha speaker range in 1991 with a clear purpose to create an affordable loudspeaker that is focused on performance first, by leveraging the research conducted at the Canadian National Research Council (NRC) over many years by PSB’s founder Paul Barton. The company has now revisited its Alpha offerings with “clean sheet” designs that benefit greatly from improved materials and production techniques, not to mention an additional 30 years of experience.
In PSB’s new Alpha range, the P3 and P5 are classic two-way bookshelf designs that can be placed on a stand, a shelf, a desk or a table and are equally well-suited for home theater or stereo listening. The T20 tower adds an additional woofer in a larger floor-standing cabinet yet occupies a small footprint. The C10 center channel speaker can be used either as the dialogue loudspeaker in a home theater or for music.
According to the press release, for the new Alphas, PSB developed two new woofers; a 4.5-inch and a 5.25-inch, both employing dual-layer voice coils with powerful magnet structures to provide low distortion and high output levels. The cones are made from a special textured polypropylene compound that prevents cone breakup and extends frequency response for smooth integration with the new tweeter, a 3/4-inch (19mm) design used in all four models. The new driver is ferrofluid cooled and features a Neodymium magnet for high sensitivity and power handling. A waveguide helps match the response of the tweeter near the crossover point with the woofer for a seamless transition. The crossover is a fourth-order, acoustic Linkwitz-Riley filter design.
Each model's cabinet has a unique combination of wall thickness and bracing to control resonances and provide a perfect platform for the drive units. The internal damping material is specialized for the purpose having been developed over many years on much more expensive PSB models and positioned precisely for optimum effectiveness, the company says.
