KEF KW1 Wireless Subwoofer Adapter Kit BLACK

The KEF KW1 Wireless Subwoofer Adapter Kit provides a convenient, high-performance solution for connecting compatible KEF subwoofers without running long audio cables across the room. Consisting of a compact wireless transmitter and receiver, the KW1 allows greater freedom in subwoofer placement while maintaining the detail, impact and precision of low-frequency audio reproduction.

Using advanced digital wireless technology operating in the 5.2 GHz and 5.8 GHz frequency bands, the KW1 transmits high-resolution audio at up to 24-bit/48 kHz. With a line-of-sight transmission range of up to 30 metres (100 feet), latency below 17 milliseconds and intelligent radio frequency selection, the system delivers reliable wireless audio for music and home theatre applications.

Designed for seamless integration with compatible KEF equipment, the KW1 supports KEF Kube 8b, Kube 10b, Kube 12b and KF92 subwoofers, as well as systems using KEF LSX, LS50 Wireless and LS50 Wireless II speakers. The discreet Black transmitter and receiver are engineered to integrate neatly into an entertainment system without drawing attention to themselves.

High-Resolution Wireless Audio Transmission

The KW1 uses a dedicated digital wireless connection to deliver audio at 24-bit/48 kHz resolution. Operating in the 5.2 GHz and 5.8 GHz frequency bands, the system provides the bandwidth required for detailed low-frequency reproduction without the need for a conventional subwoofer signal cable.

Its wireless audio architecture is designed to preserve the dynamics, clarity and impact of music and movie soundtracks while allowing the subwoofer to be positioned independently of the main audio equipment.

Flexible Subwoofer Placement

Conventional subwoofer installations often require long RCA cables between the amplifier and subwoofer, limiting placement options or creating visible cable runs. The KW1 eliminates this restriction by transmitting the audio signal wirelessly between its transmitter and receiver.

With an operating distance of up to 30 metres (100 feet) under line-of-sight conditions, the system provides flexibility for positioning a compatible subwoofer where it performs best acoustically and integrates naturally into the room.

Advanced Radio Frequency Selection

The KW1 incorporates an advanced radio frequency selection algorithm designed to identify a suitable wireless channel and maintain dependable communication between the transmitter and receiver.

Selectable 5.2 GHz and 5.8 GHz operation helps the system manage wireless transmission conditions, while data encryption protects the communication link during normal operation.

Ultra-Low Latency Performance

Accurate timing is essential for proper integration between a subwoofer and the main loudspeakers. The KW1 is designed with transmission latency below 17 milliseconds, allowing wireless low-frequency audio to remain closely synchronized with the rest of the sound system.

Its frequency response of 10 Hz to 20 kHz ensures that the wireless connection can accommodate the full range of audio frequencies required for subwoofer applications.

Compact Transmitter and Receiver

The KW1 system consists of two discreet components. The compact transmitter connects to the audio system and receives power through a 5V USB connection. The receiver connects directly to the expansion port of a compatible KEF subwoofer and receives its power through that connection.

This arrangement minimizes additional wiring and, in compatible installations, eliminates the need for a separate power adapter at the subwoofer receiver.

Expand to a Dual-Subwoofer System

The KW1 can also support a second compatible KEF subwoofer through the addition of an optional KW1 RX receiver, sold separately. A single KW1 transmitter can send the same wireless audio signal to two receivers, allowing two subwoofers to operate from one source.

Using two properly positioned subwoofers can help achieve more consistent bass distribution throughout a listening room, improving low-frequency performance across multiple seating positions.

Designed for Compatible KEF Systems

The KW1 Wireless Subwoofer Adapter Kit is designed for integration with KEF Kube 8b, Kube 10b, Kube 12b and KF92 subwoofers. It is also suitable for use in systems incorporating KEF LSX, LS50 Wireless and LS50 Wireless II loudspeakers.

The combination of high-resolution digital transmission, compact hardware and straightforward pairing makes the KW1 a practical solution for creating a clean, flexible wireless subwoofer installation.
