KEF’s KC62 Subwoofer Packs 1,000 Watts Into A Tiny Cube

KEF

When describing subwoofers, words like “large” and “bold” are almost required. Yet the new KEF K62 subwoofer, valued at $ 1,500, inspires an entirely new set of words such as “compact”, “clean” or even “cute”. One look at the photos and you’ll understand why: at just 10 inches per side and weighing 31 pounds, the KC62 launching today is darn adorable.

The KC62 is available in black or white and looks like the robot child that WALL-E and EVA could one day have produced if robots actually had children. But don’t let its size and sleek exterior lull you into thinking this subwoofer isn’t the one for you. 1,000 watts of low-end power live in its tiny frame.

What makes the KC62 different from any other subwoofer on the planet cannot be seen. The ultra-compact aluminum shell houses two of KEF’s new 6.5-inch uni-core drivers for force suppression. To build two such drivers into one speaker enclosure, you usually need a lot more space than a 10-inch cube can offer. Uni-core drivers, however, are arranged in a horizontally opposed layout and critically share a single magnet system. To save even more space, the two voice coils are concentric – one actually fits into the diameter of your partner.

According to KEF, this enables the cabinet size to be reduced by more than a third while reaching or exceeding the driver deflection of a much larger subwoofer.

The KC62 also houses two other new KEF technologies. Its P-Flex Surround anchors the driver cone to the wall of the case in a pleated design that KEF says was inspired by origami, the Japanese art of folding paper. This surround design withstands the internal air pressure created by the riders without adding excessive bulk. The company claims that the KC62 offers greater precision and detail.

The other advancement is KEF’s Smart Distortion Control technology which automatically monitors the current in the voice coil and looks for and corrects nonlinear data
Distortions. KEF engineers say this system can reduce total harmonic distortion (THD) by up to 75%.

If the bulk of the KC62 is just clean cuteness, it should be made clear on the back of the subwoofer that this isn’t a toy. There are numerous connection options, including LFE and stereo RCA plugs for inputs and outputs. While the KC62 isn’t wireless per se, it is compatible with KEF’s 200 KW1 wireless subwoofer adapter, which makes room placement hassle-free as long as you have access to power.

Speaking of room placement: The adjustments you can make to the KC62 include location-related optimizations. On the back there is an EQ selector switch with which you can choose from five presets: Free space next to the wall, in a corner, in a closet or in a special apartment mode.

Whether you take advantage of the tiny size of the KC62 and hide it or place it outdoors where everyone can admire its bewitching shape, hopefully at $ 1,500, it’s the last subwoofer you’ll ever need to buy.
