PSB is one of the best-known manufacturers of high-end loudspeakers in Canada. Founded in 1972 by Paul Barton, the company ha established a reputation for offering exceptional performance in products that are accessible to consumers interested in hi-fi but who are unable to afford the exorbitant prices offered by some of the competition.
Much of PSB's success is due to the fact that it conducts all research at the National Research Council in Ottawa. Paul Barton and PSB were the first loudspeaker maker and company to use the NRC when they began there in 1974. The NRC facilities have enabled Barton and his engineering team to amass a wealth of knowledge regarding the interactions between loudspeakers, listeners and room acoustics. Their extensive speaker analysis and double-blind listening tests have allowed them to produce speakers that offer exceptional value.
Over the past 30 years, PSB's design goals have been to build speakers that accurately reproduce a wide frequency and dynamic range, and have neutral tonal balance and realistic imaging. With the launch of the first Image series, PSB introduced cost-effective manufacturing techniques that are still employed in the updated Image line. This includes the use of a 1" ferrofluid-cooled aluminum-dome tweeter shared by all models as well as 5 1/4" and 6 1/2" injection-molded metalized polypropylene woofers used in different configurations across the line. The advantage of using the same tweeter and just two woofers in various combinations is that PSB is only required to make four different front baffles in which to mount the drivers. From a manufacturing standpoint, this lowers production costs when large numbers of speakers are built, because each model is merely a variation on a theme. The drivers and crossovers of each of the eight Image models are individually optimized for their unique enclosures, so that everything is fine-tuned to enhance the performance of each speaker.
The $749 USD-per-pair T45 uses two of the aforementioned 5 1/4" midrange/bass drivers in conjunction with a 1" tweeter in a two-and-a-half way design. The tweeter handles everything above 2.2kHz, and the midrange hands off to the bass driver at 500Hz. The T45 is referred to as a two-and-a-half-way because one 5 1/4" driver does double duty, handling both the midrange and upper-bass regions. PSB rates the frequency response at 35Hz-23kHz +/- 3dB. Low-frequency extension is down 10dB at 30Hz. Anechoic sensitivity is 90dB/W/m, with approximately 93dB/W/m being the case in a typical listening room. In combination with nominal impedance of 6 ohms and minimum impedance of 4 ohms, the T45 presents a relatively easy load for any reasonably powerful amplifier. A solid 50 watts per channel would be a good place to start.
The cabinet is constructed of what PSB describes as "heavy non-resonant wood composites" that utilize extensive cross-bracing. Each speaker measures 36"H x 7"W x 14 5/8"D and weighs 37 pounds. All drivers are magnetically shielded to allow placement next to a video monitor. Wiring is accomplished via dual five-way gold-plated binding posts that accept banana plugs, spades or bare wire. The second set of binding posts provides the option for biamping or biwiring. Furthermore, the inclusion of two ports on the front of the cabinet means that the T45s can be placed closer to the wall behind them if necessary
