Hidden Bass - KEF Ci200TRb In-wall Subwoofer Speaker This in-wall subwoofer hides discreetly yet delivers serious impact. The Ci200TRb occupies less than 59 mm of wall or ceiling depth, fitting into tight cavities without compromising performance. It blends into your space while remaining firmly committed to deep bass delivery. Powerful Its 200 mm (8-inch) ultra-slim T‑Series driver moves enough air to produce generous low frequencies. In passive mode, it gives warm, controlled support. In active mode, it connects with KEF’s KASA500 amplifier to deliver thunderous output that anchors home-theatre soundtracks or music with authority. Adaptable You can configure the Ci200TRb in stereo (two‑channel) or mono (single-channel) mode, depending on your installation. The built-in crossover ensures smooth integration when used in passive setups. If you run it active, the internal DSP works seamlessly with KASA500 to maximise output and efficiency. Discreet The magnetic grille and paintable ultra-thin bezel allow the subwoofer to disappear into your décor. You don’t need to compromise design for performance — the Ci200TRb gives you refined, room-matching aesthetics without affecting bass depth. Durable Installation stays secure thanks to dog-leg mounting hardware that grips firmly into plaster or drywall. The low mounting depth and rugged build suit both residential builds and professional installs. Once in place, the subwoofer stays steady and delivers consistent bass for years.
