Boston Acoustics PV-500 Subwoofer

Boston Acoustics PV-500 sub looks very elegant. On the front panel there is only a stylish volume control. A 250-mm driver radiates down and the large bass-reflex port is placed on the back wall. DCD-technology is used in the driver, which provides substantial speed of diffuser. Basstrac scheme allows avoiding distortions at overload and at the same time pickup signal doesn't lose the form. 2 linear inputs are available: through built-in crossover and direct. Also there are 4 spring input terminals for high-level signal. Any outputs are absent.

Sound. Boston Acoustics PV-500 sub required to tinker at settings. Gain band, in which the model has weighty and focused bass, turned out to be quite narrow. If you turn volume up or down, the material loses form and blurs. In a movie Boston features are almost invisible. Here the sub is able to juggle with bass dumbbells and rush LF-wave. Do not twist volume knob to maximum, so the sound overflow the banks.
