The CT165 is a class leading ceiling speaker that delivers well beyond its price point. Packed with the proprietary technologies and materials found in Monitor Audio’s award winning loudspeakers, the CT165 offers unbeatable audio performance and value for money.
As one of our best selling ceiling speakers, the Monitor Audio CT165 is most commonly used with multi room audio systems such as Sonos and Control4. Its compact size and discreet appearance make it the perfect choice for listening to music in small to medium sized rooms.

The CT165 is a two-way speaker that combines Monitor Audio’s MMP II bass driver with a C-CAM gold dome tweeter to provide high-performance sound. Optimum set-up is achieved via a pivoting tweeter and high-frequency (+3dB / 0dB /-3dB) level adjustment. The CT165 is a firm favourite amongst our specialists and one of our most recommended ceiling speakers for its flexibility and dynamic audio performance. The CT165 is also available as a sonos bundle deal.
