About the KEF KF92

Let's get deep

Who doesn't love at least the occasional dose of deep, hard-hitting bass? I haven't yet met that person. But for the rest of us, thank goodness there are subwoofers like KEF's surprisingly compact, totally high-tech KF92. Its dual 9" hybrid aluminum woofers are arranged back to back, in a configuration that cancels out the forces that can cause unwanted interaction with the cabinet. Translation: purer bass that can get immensely loud. (KEF even puts a number on it: up to 110 dB, which is rock-concert volume level.)

Designed for accurate, musical bass

But this wouldn't be a KEF sub if it was all about playing loud. Each woofer is made up of a shallow aluminum skin atop a paper cone. This hybrid design allows very precise movement, for dynamic, accurate bass. And each features a huge motor system and vented voice coil, for dynamic, fluid bass that goes down well below the human hearing threshold.

Intelligent processing optimizes the sound

KEF's IBX (Intelligent Bass Extension) is a digital signal processing engine that analyzes the input signal and applies customized processing to keep the bass as deep, punchy, and dynamic as possible. And along with standard controls like an adjustable low-pass filter and phase switch, the back panel has a five-position EQ switch that helps you dial in the perfect response for where you've placed the sub. Settings include, "Wall", "Corner", "Cabinet", and even "Apartment."

Part of a complete KEF surround sound system

The KEF R Series features an array of speakers that are voice-matched for compatibility in an immersive surround sound system:
