Departing from the standard box shape the Image B25’s front, top and side panels all sport gentle curves. The B25 uses a 1-inch aluminum dome tweeter and a sleek looking 6.5-inch metalized polypropylene woofer.
Paul Barton, founder and chief designer of PSB Speakers has probably logged more hours at the Canadian National Research Council’s facilities in Ottawa, Ontario, than any other designer. There he conducts extensive “blind” tests, where panels of listeners compare old PSB models and competitors speakers to Barton’s current project. The process of refining a new speaker can stretch out for years. Barton designs individual drive units and complete speakers.
Tip: Barton designs his speakers to sound best with their grilles in place, better leave them on.
All of that testing paid off, the B25 is a very neutral sounding speaker. Bass goes fairly deep while maintaining excellent definition, the midrange is quite clear, and the treble is extended, though a trifle bright. The speaker handles power well and can play loud.
Pumping up the White Stripes’ Icky Thump CD [Warner Bros.] proved the Canadian speakers weren’t afraid to rock and roll. Jack White’s raunchy guitar riffage plastered a big smile on my face and Meg White’s drums packed a seriously powerful wallop. The Stripes’ tunes are rhythmic, hard and loud, but the B25s low-distortion, highly transparent sound also flattered all kinds of music.
