KC62 Subwoofer - Compact Subwoofer

STEREONET PRODUCT OF THE YEAR AWARDS 2021 - SUBWOOFER

“It looks great, doesn't take up much space (at 246x256x248mm) and packs 1kW of power from twin 500W Class D power amps. Its strong, light magnesium cabinet is a work of art, and it's a highly effective bass maker, punching out up to 105dB of tremulous low frequencies despite those diminutive dimensions.” - StereoNET, Dec 2021

FULL REVIEW

Don’t let the size fool you

Deep and powerful bass is no longer solely the domain of big-shouldered, massive subwoofers. KC62 is David to their Goliath; an ultra-compact subwoofer capable of delivering accurate, deep bass for an immersive music, movie and gaming experience at complete odds with its modest dimensions. And just as David beat Goliath, so KC62’s performance renders these subwoofer behemoths obsolete.

Uni-Core^® Technology

Craving an immersive entertainment experience but put off by bulky subwoofers? KC62’s patented Uni-Core^® technology revolutionises the traditional force cancelling design to deliver deep accurate bass from an ultra-compact cabinet. Combining both drivers into a single magnet system allows cabinet size to be reduced by over a third, while also increasing excursion to unlock exceptional output and depth.

1,000W RMS

Turn up the Power

KC62’s twin drivers are powered by 1,000W RMS (2 x 500W) of specially designed Class D amplification, providing exceptional levels of control and the ability to deliver sudden bursts of power when required, for example when enjoying your favourite high-octane action sequence.

5 Pre-sets

Same performance, everywhere

KC62 slips effortlessly into any environment or listening room, with the five pre-set Room Placement Equalisation feature ensuring the same performance no matter where you decide to place it; in free space, next to the wall, in a corner, nestled within a cabinet or using the dedicated apartment mode.

Well Connected

KC62’s connection options allow it to be used with almost any audio system, with KEF SmartConnect and speaker level inputs eliminating any connection issues. Line output with High Pass Filter (HPF) allows for exceptional fine-tuned integration, and KC62 is also compatible with the KW1 for simple wireless compatibility.

Design meets substance

Crafted from extruded aluminium, KC62’s curved cabinet perfectly blends form and function, providing strength and beauty. Small enough to blend into any décor, the Carbon Black, Mineral White and Titanium Grey finishes also make KC62 an exceptionally attractive statement.

Accurate, deep bass with speed and power

Accuracy is a KEF hallmark, whether in full-range loudspeakers or in subwoofers dedicated to delivering sensational bass. An array of innovative technologies come together to ensure KC62’s bass accuracy, including the P-Flex surround for precise driver movement and Smart Distortion Control Technology that reduces distortion, while performance is maximised via KEF’s Music Integrity Engine.

P-Flex (aka Origami Surround)

The P-Flex driver surround has a unique pleated design inspired by Origami, the Japanese art of paper folding, engineered to better resist the acoustic pressure in the cabinet to allow the driver to move more precisely compared to traditional surround designs. The result is deeper bass extension and a more accurate and detailed bass reproduction.

STEREOPHILE

“In my listening room, KEF's sleek, small KC62 sub merged successfully with three high-quality loudspeakers—including KEF's own LS50. In each case, the KC62 subwoofer did more than add bass: It took an already great speaker and made it greater. Isn't that what a subwoofer is supposed to do? ” - May 2021

Unbelievable sub bass.

I have three of these little marvels, two at the front shadowing my ATC SCM40 speakers and the other under and at the back of my sofa for 5.1 duties. The ATCs have good bass, but the KC62s adds those vital extra low octaves of sub frequencies particularly with some of my organ recordings e.g, Saint-Sans Organ Symphony, you can really feel those big pipes.
I am amazed that something as diminutive as the KC62 produces such amazing bass, the Blu-ray DVD of Wish You Were Here really gets my three subs singing in 5.1!

Refined bass

KEF KC62 Subwoofer. It's absolutely amazing. Small, compact size without compromising that heavyweight, refined bass I was looking for. I went with the titanium grey. Build quality on point, stylish, powerful. I highly recommend it!

I also bought the KW-1 Wireless subwoofer adaptor kit. It works flawlessly.

Although I'm not impressed with no type C to Micro USB cable. I have the LSX II Wireless Speaker, which has a type C USB charging function.

I don't understand why a cable or adaptor wouldn't be supplied, especially when you can power the kw-1 wireless kit via the LSX II.

Fantastic subwoofer that you can feel as well as hear. A great addition to the LSX II LT speakers. Highly recommended.
