PSB Speakers Synchrony One B Bookshelf speakers
Among the competitors PSB Synchrony One B stand out not only for chic finish and the highest build quality, but also for unconventional arrangement of drivers relatively to each other. Usually tweeter is placed in the upper part of the body, here everything is the opposite - a 165-mm mid-woofer with the membrane made of fiber glass is on top. But on the second thought this solution is justified - bass becomes clearer due to smaller reflections from floor and tweeter is almost at the head level of the seated listener. Four ordered crossover is assembled from high-quality components. The tuning frequency is 2200 Hz, all links are coordinated in order to achieve in-phase radiation of drivers.
As befits loudspeakers of such class, there is the possibility of two-wire connection with an amplifier. In a heavy body both metallic (front and rear panels, which form a unique frame) and massive MDF panels are combined successfully. The construction at the same time turns out to be extremely damped and behaves as a real monolith when tapping.
PSB Synchrony One B gives clear and well balanced sound at any volume. Aurally you won't notice obvious coloring, however, sometimes some boominess of bass is caught, caused, most likely, by side-tones in bass-reflex port. The lower case is unusually powerful, absolutely untypical for shelf speaker system. Such a confident entry to depth is rather typical for floor standing speaker systems of medium size. Dynamic potential of One B is also quite impressive, due to which any musical material is transferred with correct contrasts.
We liked very much the playback of the upper band. Keeping high resolution, the sound does not have metallic taste, being typical for titanium drivers. Against the background of increased attention to the edges of the range, the middle is perceived to be too neutral and detached. However, slight lack of colors in vocals does not spoil overall impression. Spacious characteristics of PSB One B are also normal and do not have special deviations. Moreover, they even slightly exceed expectations from the loudspeakers of this cost. You should only install them very carefully.
