Key Technologies
Uni-Core®
Maximises bass, minimises space
Uni-Core® combines both back-to-back drivers into a single motor system. The overlapping, concentrically arranged voice coils allows for far more driver excursion than in other force cancelling design, unlocking more output and depth from less space.
Each unique Music Integrity Engine® is precisely tuned to allow all components within the individual subwoofer to work in perfect harmony, elevating the overall performance for remarkable integrity, detail, and accuracy of sound.
The pleated structure resists internal air pressure, allowing the driver to move precisely as dictated by the audio signal. The result is a deeper bass extension and more accurate, detailed bass reproduction.
The benchmark of subwoofers
Our flagship twin 9-inch driver force cancelling subwoofer is hand built in the UK. A truly extraordinary subwoofer, Reference 8b delivers exceptional bass precision and control.
These class-leading subwoofers use technology derived from the Reference and R Series to deliver accuracy and incredible depth. The twin-driver force-cancelling configuration with P-Flex Surround design deliver performance beyond their room-friendly dimensions. KC92 is the perfect balance of discreet size and impressive performance, while KC62 is when size matters.
Celebrating 60 years of acoustic innovation, LS60 Wireless is our vision of high-fidelity sound for the future. An all-in-one speaker system that allows you to stream from any source and connect to any home audio devices with audiophile-grade power.
Versatile for effortless immersion
Kube subwoofers allow you to explore new depths of sound. Enhanced by Music Integrity Engine®, Kube delivers optimised performance with exceptional depth and dynamics. With 4 sizes in the range with flexible connectivity, Kube is designed to effortlessly adapt to any setup and anywhere you place them.
Uniquely slim
Easy to conceal thanks to its uniquely slim profile, the T2 delivers fast, uniformly dispersed and devastatingly accurate bass and features a 250 Watt Class D amplifier and 10-inch driver.
A subwoofer is a speaker specialised in reproducing the very lowest frequencies in music and movies. Adding a subwoofer to your sound system builds out the sound further for superb detail and allows you to feel the depth of the bass in your chest physically. Typical examples of low frequency sounds include the bass guitar in Another One Bites the Dust or explosions in action movies.
What are active and passive subwoofers?
All of our standalone subwoofers are active, meaning that they have an amplifier built in so that you can enjoy rumbling, deep bass right away. A passive subwoofer doesn’t have an amplifier built-in, so it will have to be connected to an amp to drive powerful sound. All our architectural subwoofers are passive.
Where should a subwoofer be placed?
It can take a little bit of work to find the best place for your subwoofer. The room, your speaker/listening position and your own preferences all play a part. Sometimes, a subwoofer just has to go where it will fit. KEF understands this, and has included a number of features to help really dial in your subwoofer, no matter where it is placed.
For example, "EQ" mode in KC92, KC62 and the Kube MIE range was developed to help ensure excellent performance no matter where in the room the subwoofer is placed. Choose one of five possible room placements and let the system adjust the settings automatically to give you the best sound possible.
A single subwoofer revolutionises your listening and can be a great addition to your setup. As your system grows over time, adding more subwoofers can help reduce negative effects of standing waves. Standing waves produce dips and peaks at certain frequencies throughout the room – the use of multiple subwoofer positions can smooth out the bass performance throughout the room, creating a more consistent sound experience.
Subwoofers placed very close together playing the same audio will acoustically couple – essentially acting like one larger subwoofer. Whilst this has the effect of creating more output (up to an additional 6dB), the biggest benefit is that each subwoofer can be played at a lower volume than a single one for a given output level. This enables the subwoofers to increase headroom for a more dynamic performance. For this reason we designed the KSK92 Stacking Kit, which allows for the KC92 subwoofer to be stacked vertically.
Which subwoofer should I choose?
We offer a wide range of subwoofers to bring exquisite bass to listeners of all kinds. From the excellent value of the Kube MIE range to the exceptional Reference 8b that blasts bass through your space for phenomenal parties and immersive movie nights, KEF will surely have the right active subwoofer for your home.
Whilst it may be tempting to opt for the largest subwoofer you can fit into your room, bigger is not always better. We recommend you choose a subwoofer that appropriately matches the size of your space and your other speakers.
Why choose a KEF subwoofer?
At KEF, we have created groundbreaking audio equipment since 1961, when we were founded to remain always on the cutting edge of audio. Our subwoofer range was created from this wealth of expertise, passion and ambition.
By treating and designing our subwoofers in exactly the same way as our main speakers, we don't just go deeper. We go beyond the boom, bringing the performance you love about your main HiFi speakers into an even fuller experience. Containing unparalleled technology like the Uni-Core Driver Configuration and Music Integrity Engine, you simply won’t find subwoofers like this anywhere else.
How do I connect a KEF subwoofer with speakers or an amplifier?
Our active subwoofers can be easily set up with LS Wireless Collection speakers through the KEF Connect app by simply choosing the relevant subwoofer from the list in the app’s EQ profiles. This will set the relevant crossovers and gain settings. See our guide to integrating the subwoofer with LS wireless speakers for more tips.
The Wireless Subwoofer Adapter Kit (compatible with KC92, KC62 and Kube MIE subwoofers) enables easy subwoofer setup with any speaker without the limitation of additional cables. Simply attach the Receiver to the subwoofer and the Transmitter to your wireless speaker or amplifier, if using passive speakers.
Alternatively, you can purchase an RCA subwoofer cable to connect your subwoofer to a wireless speaker or an amp. All active subwoofers except the T2 feature this connection option.
