Summary of Contents for Bowers & Wilkins PV1

  • Page 1 Development of the PV1...
  • Page 2 The Problem The holy grail of subwoofer design is deep and clean bass from a near-invisible box. The immediate problem that arises is that reduced box size both curtails bass extension and increases pressure on the enclosure wall and driver diaphragm. Many small subwoofers are unable to reproduce sufficiently extended bass and suffer from considerable cabinet coloration, often resulting in bass that is uneven...
  • Page 3 To illustrate this, there are two analogies that we can apply. The first is the soap bubble. An undisturbed bubble assumes a spherical shape because the pressure difference inside and out is perfectly balanced by the only force the bubble can sustain - surface tension that is entirely in the curved plane of the skin.
  • Page 4 PV1 - Concept The PV1, launched in June 2004, was developed directly from this prototype. From a sphere that comfortably passes through a basketball hoop, it creates truly extended bass that defies its diminutive and gorgeous exterior in both quality and quantity.
  • Page 5 floor, with the potential of radiating sound into a room below the listening room. This can be a particular problem in apartments. With the PV1, there is no rocking motion generated and the device is inherently stable. The subwoofer therefore rests on a circular rubber base that mechanically isolates it from the floor, yet it retains...
  • Page 6 EQ = i EQ = ii EQ = iii Bandpass output level 90dB at 1m The vibration levels of the PV1 (red) are compared with those of a conventional subwoofer (blue) of similar bandwidth, output capability and drive unit radiating area, but using a single 250mm driver in a heavily braced wooden cabinet.
