Best For large Room: KEF balanced Input Subwoofer

Buy on Amazon

We would, of course, be remiss if we didn't mention kef balanced input subwoofer for daily purpose. It is the brain behind the kf92 intelligent bass extension that optimises the relationship between the amplifier drivers and cabinet. It is engineered to blast out low frequency energy, yet is subtle enough to pick out the delicate details of a double bass. Even at high volumes the box has no vibrations whatsoever as its design is pretty astonishing. It improves timing accuracy and dynamic response, producing a more detailed sound closer to that in the studio. The low frequency response is just extraordinary and you can feel the air compressing around you.

The small footprint is an amazing engineering feat from KEF with the dual opposing driver configuration. All you get from this is very clean natural sounding bass and nothing else. The KEF is cleaner and goes tremendously lower. It allows kf92 to be used in any system installation with minimal fuss.

Why We Like This:

A very forgiving subwoofer in terms of room placement
Great for classical, jazz and rock music
Good investment for long term
