A secondary consequence of the use of twin opposing drivers is the inherently balanced kinetic nature of the device. It is well known that the reproduction of bass with correct dynamics requires a firm, solid foundation – sometimes referred to as a mechanical ground. It is the reason that speakers stand on spikes. A practical downside is that some vibrational energy is transmitted to the 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 an effective foundation.

A simple, yet effective demonstration of the inertness of the enclosure is to touch it while the subwoofer is playing loudly. There is virtually no discernable movement.

PV1 – Technical information

The listening experience reveals a subwoofer with incredible transient response and pitch definition. However, the enclosure design is not the only reason for this. The driver diaphragms themselves also have to be stiff enough to resist any tendency to deform when subjected to the pressures generated inside the enclosure and the forces from the voice coil. A very rigid sandwich construction is therefore employed, with a concave aluminium outer layer, a mica cone at the back and an expanded polystyrene core.

Any compact subwoofer will require substantial equalisation in order to have an extended low-frequency response and this implies a high-power amplifier. The PV1 utilises a 500W ICEpower® module, which allows considerable output levels to be generated without audible distortion. The aluminium enclosure acts as the heat sink.

Naturally, the driver must be capable of handling this power. The large magnet structure aids control of the motion of the diaphragm and forms an effective heat sink for the voice coil, which, at 30mm long, allows sufficient linear movement. A double rear suspension ensures that the coil remains in line throughout the large excursion.

PV1 specifications

Bowers & Wilkins has long been synonymous with high-quality audio equipment, and the PV1 subwoofer stands out as a compelling offering in its range. Launched with an elegant design and innovative technology, the PV1 not only delivers deep, resonant bass but also complements modern home aesthetics.

One of the main features of the Bowers & Wilkins PV1 is its unique driver configuration. The subwoofer is equipped with a pair of 8-inch drivers that are strategically positioned to optimize sound dispersion. This design enables the PV1 to produce powerful bass frequencies without distortion, making it an ideal choice for both music enthusiasts and movie lovers. The drivers work in tandem with a high-performance 250-watt digital amplifier that ensures dynamic and accurate sound reproduction across various genres.

The PV1's enclosure is another hallmark of its design. Constructed from rigid materials, the cabinet is shaped like an oval, which not only enhances its visual appeal but also helps reduce standing waves and internal resonances, resulting in cleaner sound output. This attention to detail ensures that listeners experience the full depth of low frequencies, immersing them in their favorite music and films.

Bowers & Wilkins has also incorporated its innovative Flowport technology in the PV1. This system features a specially designed port that minimizes turbulence caused by air movement, thereby reducing unwanted noise and allowing for a more nuanced bass response. This results in a clean, articulate low-end that enhances the overall listening experience.

Another significant characteristic of the PV1 is its adaptability. The subwoofer is equipped with adjustable settings, allowing users to tailor the bass response to suit their specific environments and preferences. Whether placed in a small room or a large open space, the PV1 can be calibrated to deliver optimal performance.

For ease of integration within home entertainment systems, the PV1 includes a range of connectivity options, including high-level and low-level inputs. This versatility makes it compatible with various audio setups, ensuring that users can enjoy high-quality bass regardless of their equipment.

In summary, the Bowers & Wilkins PV1 is a premium subwoofer that blends cutting-edge technology with sophisticated aesthetics. With its powerful drivers, innovative cabinet design, Flowport technology, and adaptability, it provides an exceptional listening experience that can satisfy the most discerning audiophiles. Whether for music or home theater use, the PV1 is an outstanding choice for those seeking superior bass performance.
