The ATC HTS11C is the horizontal center version of the HTS11 and has been specifically developed for home cinema and multi-channel systems. As a passive 2-way on-wall loudspeaker, it combines signature ATC studio technology with a slim, wall-mounted enclosure, making it ideal for discreet installations below or above screens.

At its core is a highly precise and neutral reproduction of speech. The 150mm CLD (Constrained Layer Damping) mid/bass driver ensures controlled, low-distortion midrange and surprisingly deep bass for a wall-mounted design, while the 25mm soft-dome tweeter delivers clear, finely detailed high frequencies. This results in film dialogue that is extremely intelligible and stably positioned within the soundstage.

By mounting it close to the wall, the HTS11C acoustically benefits from the room boundary, which supports efficiency and the low-frequency range without sacrificing precision. At the same time, the signature ATC voicing is preserved: neutral, dynamic, and highly controlled rather than tonally colored.

The HTS11C is designed to integrate seamlessly into HTS systems, creating a stable, wide soundstage between the front speakers. Especially in combination with HTS11 or HTS40 models, it creates a homogeneous, professional home cinema setup with clear vocal imaging across all seating positions.
