KEF Ci160ER Subwoofer

The Ci160ER pairs its 8-inch driver with an integrated amplifier in the ceiling, so it can't match a big floorstanding sub, but in-ceiling placement near a wall or corner reinforces low frequencies. For music and moderate home theater depth, it delivers honest mid-bass while staying completely hidden.

Correct — the built-in amp means you don't run speaker wire to a rack; instead the unit receives signal wirelessly from a transmitter connected to your receiver or streamer. You still need mains power at the ceiling location, so plan wiring during installation.

It's a retrofit-style install: you cut a hole in the drywall, wire power, and clamp the unit in place, but you must first verify joist bays and avoid pipes, ducts, and lighting runs. An installer with a stud finder and drywall saw can typically do it in a couple of hours per unit.

KEF's floorstanding Kube series and competitors like SVS's SB line use larger cabinets and drivers for deeper extension and higher output. The Ci-series sub trades raw performance for invisibility — it's the choice when aesthetics rule, not when you want cinema-grade 20 Hz rumble.
