On rare occasions it’s hard to associate the equipment before you with the sound you’re hearing. Take as an example the amazing KEF KC62 subwoofer – it’s tiny at just 25cm per side, with a pair of drivers just 16.5cm in diameter, and yet this seemingly miraculous speaker delivers massive, fast and tautly controlled bass down to subterranean depths. So the KC62 is so small you can hide it away almost anywhere, but the performance is all down to clever design – the opposed drivers use Uni-Core force cancelling, each powered by a 500W amplifier, all under the control of digital signal processing.
