Ultra-Compact, Mega-Great
Ultra-compact and mega-great, the PSB B4 sub-compact monitor is comprised of a new four-inch woofer and a one-inch titanium tweeter. Intended for home theater or multichannel applications, the two-way system fits in a cabinet only 5-1/4 inches wide by 9-1/8 inches high by 6-1/2 inches deep, making it as easy to place as a conventional bookshelf speaker.
The B4 shares the injection-molded, clay/ceramic-filled polypropylene designs of the Tower drivers, which also include dual magnets, polycarbonate baskets, and rubber surrounds. It is rated up to 80 watts at 6 ohms. The compact size is ideal for today’s urban, modern decors.
The B6 features 40mm rear ports and, like the Towers, PSB’s sturdy multiway gold-plated binding posts that accept bare wire, lugs, banana plugs, open and closed spades, and enable bi-wiring and bi-amplification. Bi-wiring reduces interference by allowing the two channels to separate electronically when routed through an amplifier. Bi-amping allows the use of two amplifiers to separately power the woofer and the tweeter.
Along with more robust baffles made from 1-1/8-inch thick MDF, a material usually reserved for more expensive models, the new Image speakers exhibit a highly finished look, with clean and soft, esthetically pleasing lines and no visible fasteners.
New Heights of Performance and Sophistication
PSB introduces a dramatically new edition of its successful Image Series speakers benefiting from top-level technology trickled down from the highly acclaimed Synchrony and Imagine Series. Many of the features that debuted in the flagship Synchrony Series in 2007, and then introduced to the stylish Imagine Series in 2008, are now available in the all-new Image Series.
Long considered among the most versatile and affordable of PSB's major speaker lines, Image Series speakers have been remodeled and equipped with many of the features and enhancements developed in recent years for PSB's award- winning Synchrony and Imagine Series loudspeakers. Scaling the size of the whole Image project was a major objective.
The new Image Series represents the final stage of a profound three-phase reconsideration of PSB product offerings in freestanding speakers that began with Synchrony, then moved to the Imagine Series. With the new Image Series, PSB again raises the traditional PSB virtues to new heights of performance and sophistication, whether judged technically or by rigorous standards of subjective evaluation.
Fundamental Acoustical Research
Like all PSB speakers, the new Image designs benefit from the world-class acoustical resources of Canada's National Research Council in Ottawa, Canada. For more than 35 years PSB founder and design team chief Paul Barton has returned again and again to the NRC to conduct fundamental studies of loudspeakers and room acoustics in its anechoic chamber as well as vital subjective evaluations in its listening-studio facilities. Mr. Barton's research at the NRC, which included an extensive three-year development project for Synchrony, played an important role in the design of the new Image Series. |
