The ATC HTS11C On Wall Speaker is a mid-size 2-way loudspeaker designed for high-performance home cinema and installed audio systems. It works well as a main speaker in medium-sized rooms and also as a surround speaker in larger spaces.
In addition, the HTS11C combines clean design with flexible placement options. Therefore, it integrates easily into a wide range of interiors while maintaining ATC’s focus on accuracy, clarity, and low distortion.
High-performance 2-way driver design
The HTS11C uses driver technology taken from ATC’s high-end studio monitors. In addition, it delivers high dynamic range and precise transient response. As a result, it handles both music and film soundtracks with impact and control.
CLD bass/mid driver technology
The handmade bass/mid driver uses ATC’s CLD cone technology. Therefore, it reduces distortion and improves midrange clarity. In addition, it delivers a natural and balanced sound character.
Neutral sound and low distortion
The HTS11C is tuned for neutral voicing. In addition, it keeps distortion very low across the full frequency range. As a result, it delivers clear and accurate sound suitable for both hi-fi and cinema use.
Flexible installation design
The speaker supports both portrait and landscape mounting. Furthermore, hidden wall brackets and concealed input terminals keep the installation clean. Therefore, it fits neatly into modern interiors without visible clutter.
Build and reliability
The HTS11C is hand built in England and designed for long-term use. In addition, ATC supports it with a 6-year warranty.
