Ultra-thin architectural subwoofer for custom installations
The KEF Ci200TRb is an architectural subwoofer designed to deliver deep bass even in rooms where installation space is extremely limited. Thanks to its ultra-thin 200 mm woofer, derived from T Series technology, this model allows low-frequency reinforcement to be integrated into walls or ceilings without compromising the look of the room. It is an ideal solution for custom install systems, discreet home theatres and high-end multiroom audio systems.
KEF performance in just 59 mm of depth
With a mounting depth of less than 59 mm, the KEF Ci200TRb can be installed even in false ceilings or walls with limited space. This makes it particularly suitable for modern apartments, prestigious interiors, advanced residential installations and projects where the audio has to remain almost invisible. In passive mode it adds body and depth to the KEF Ci160TR or Ci160TS speakers, while in an active configuration with the KEF KASA500 amplifier it delivers a more energetic and engaging impact.
Deep bass for music and home theatre
The KEF Ci200TRb is designed to improve low-frequency performance in flush-mount audio systems while keeping its physical presence to a minimum. It can be used in passive stereo mode, with an impedance of 2 × 8 Ohm, or in mono mode, with an impedance of 16 Ohm. Paired with the KASA500, it extends the response down to 32 Hz, ensuring more intense and dynamic reproduction for music, films and home cinema content. The discreet grille allows clean, refined integration into any room.
