What customers say
Customers consistently praise the KEF KC62 Subwoofer for its shocking performance relative to its compact size. The core theme is exceptional quality and design integration.

Know before you buy
The KC62 uses KEF’s proprietary Uni-Core technology, which combines two 6.5-inch drivers into a single, space-saving motor system. This allows for significant driver excursion within a very compact cabinet, delivering bass performance typically found in much larger units.
Yes, its compact footprint is ideal for smaller rooms where space is limited. Additionally, the five preset room placement EQs allow you to optimize the sound based on where you position the unit, ensuring balanced bass without overwhelming the room.
The KC62 is an active subwoofer with a built-in 1000W RMS Class-D amplifier, so it does not require external amplification for the drivers. You can connect it to your receiver or integrated amplifier via RCA or speaker-level inputs.
Absolutely. The Music Integrity Engine processing ensures the bass remains precise and controlled, making it equally capable of handling the subtle textures of music and the high-impact demands of movie soundtracks.
The two drivers are mounted back-to-back, which cancels out the reactive forces that cause cabinet vibration. This results in a cleaner, more accurate sound because the enclosure remains stable even when playing at high volumes.
You can use the variable low-pass filter to match the subwoofer's output to your main speakers' frequency range. This ensures a seamless transition between your speakers and the subwoofer for a cohesive soundstage.
