With the Bowers & Wilkins PV1D, the bass of a song or movie soundtrack will sound deep and un-distorted. This subwoofer has a spherical design and 2 symmetrically placed 200mm drivers. Thanks to this construction, the subwoofer doesn't have noise-induced vibrations, even at a high volume. Presets allow you to choose the bass reproduction that enhances a song or movie best. If you want to adjust the sound down to the smallest details, you can connect a USB cable to the subwoofer with a Windows computer. Download the free SubApp software and gain access to all sound settings, such as the sensitivity and frequency range.
