By 2021, the KEF audio brand will hit a new low... in terms of frequency. The company has just announced a new subwoofer model, the KC62, which uses a proprietary technology called Uni-Core that delivers unmatched bass response. Uni-Core builds on the dual-opposed drivers you may have seen in the Sonos Sub before, but mixes things up by reducing the size of the voice coil inside the driver. This allows the driver to move more air than a standard sub or dual sub, producing lower sub frequencies and reducing the overall size of the cabinet. The result, according to KEF, is a subwoofer that can go as low as 11Hz, well below what you can hear, but not below what you can feel, while still going as low as 200Hz.
A small but powerful subwoofer
At just 246 x 256 x 248mm, the KC62 is the definition of small but mighty: inside the cabinet, the KC62 will use two purpose-built Class-D amplifiers delivering over 1000 watts of power to the subwoofer. sailor capable of producing 105 dB of sound. To optimize audio sound, the KC62 uses KEF's Music Integrity Engine, a set of DSP algorithms that amplify and smooth the signal, which is essential to prevent bass sounding too bloated. In terms of connections, you'll have the choice of either an in-line or a four-pin Phoenix connector (more common in Europe than here in the US), as well as the option to use a wireless connection kit if you'd like. wireless installation. That said, the KC62 isn't cheap: it'll set you back $1,500 (£1,400, around AU$1,900), which is definitely the most expensive for subwoofers. It's a big investment, but if you're looking for big bass in a small package, it's going to be hard to beat.
