KEF BANNER

The KEF KW1 is a Wireless Subwoofer Adapter Kit comprising a discreet transmitter and receiver, delivering near lossless 24-bit/48kHz audio over a 5.2GHz/5.8GHz digital link with up to 30 metres line-of-sight range — freeing compatible KEF Kube, KC62, KC92 and wireless speaker systems from cable placement constraints.

The KEF KW1 allows compatible KEF subwoofers to be placed in the optimal position within a room without being limited by cable runs. Comprising a discreet transmitter and receiver, the KW1 works with the KEF Kube subwoofer range, as well as the KC62 and KC92 subwoofers, giving installers and listeners complete freedom to position their subwoofer for the best possible bass performance rather than compromising placement for the sake of cable access. High-quality wireless transmission ensures every ounce of detail and impact from films and music is delivered faithfully, with no perceptible compromise compared to a wired connection.

Lossless, Low-Latency Wireless Transmission

The KW1 operates on a selectable 5.2GHz or 5.8GHz high-bandwidth digital wireless link, delivering near lossless audio at up to 24-bit/48kHz resolution for pristine performance. An advanced RF selection algorithm continuously monitors and selects the cleanest available channel for stable, reliable wireless transmission, whilst latency of less than 17ms ensures audio remains perfectly synchronised with on-screen action during movies and gaming. A wide operational range of up to 30 metres (100ft) line of sight makes flexible subwoofer placement straightforward in even the largest rooms.

Simple Setup & Flexible Power

The KW1 transmitter is powered via USB, whilst the receiver is powered directly by the subwoofer's expansion port — eliminating the need for an additional power supply at the subwoofer end. Pairing between transmitter and receiver is intuitive and highly stable, ensuring a reliable wireless connection is established quickly and maintained consistently during use.

Expand to Multiple Subwoofers

The KW1 receiver is also available separately, allowing a single transmitter to send the same wireless signal to two KEF subwoofers simultaneously — ideal for dual-subwoofer setups where both units need to receive an identical wireless feed.

Broad System Compatibility

In addition to the Kube, KC62 and KC92 subwoofers, the KW1 is also perfectly suited for use with KEF's LSX II LT, LSX II, LS50 Wireless II and LS60 Wireless systems — making it a versatile wireless solution across much of KEF's current wireless speaker and subwoofer range.

    Delivery Notes

    On delivery, you must inspect the goods carefully for damage as Audio Volt is unable to accept responsibility for damage in transit, shortage of delivery or loss of products unless the customer advises Audio Volt of such within three working days from the date of delivery.

    60 Day Returns Policy

    We ask that you follow these guidelines to help us process your return as quickly and efficiently as possible:

    1. Please keep your order reference to hand. This confirms your original order and gives us the necessary details to authorise the product's return.
    2. Contact our Customer Services Team on 02476 369890 (or email info@audiovolt.co.uk). We will then send you an RMA number and a returns form, which needs to be completed and sent back with the returned item(s).
    3. If the order has been unpacked, re-package it to ensure that it is being returned in its original condition. Please make sure all items relating to the product are returned, including manuals and cables.
    4. When returning an item, please obtain a proof of postage receipt from the courier.

    Returned items must be mailed within 10 days of when the RMA number has been issued. Items received with a post date 30 days after your requested return will NOT be eligible for refund.

    Please note: our returns policy is quite straightforward, but there are a number of conditions that we ask our customers to comply with before applying:

    1. It is your responsibility to request a return. If you don't tell us you want to make a return, we don't know. Once you do tell us, we will do everything we can to action it.
    2. If you have not requested a return within 60 days of receiving an order, we will assume that you are intending to keep it, and we will not authorise a return.
    3. We always refund the payment according to how the original purchase was made and aim to do so within 72 hours of the return being received by us.
    4. Returned goods are liable for a restocking fee of 15% towards handling and repackaging if the order is not returned in its original, unopened packaging. This charge will be subject to our inspection of the returned goods.
    5. Delivery charges will not be refunded unless the delivered goods are faulty.
    6. Replacement products are dispatched immediately after the returned goods have been received and accepted by Audio Volt.
    7. Items that develop a fault within 30 days of delivery are eligible for a replacement or a refund. Delivery costs are also reimbursed for faulty items. Please contact our Customer Services Team on 02476 369890 if you believe your item has developed a fault.

    Finally, please remember that notifying us of your intention to apply for a return, saving the delivery paperwork and keeping the order in its original packaging will help both you and Audio Volt to process the return quickly.
