Premium 2-Way Angled In-Ceiling Speaker

The CS AIC 860 is not just another in-ceiling speaker. Rather it is an angled in-ceiling designed to allow the proper dispersion required to create a true three-dimensional sound stage when recessed into the ceiling. This is especially true for high performance in-ceiling stereo or home theater applications.

  • PSB technology and expertise in an Angled In-Ceiling Speaker
  • Pivoting Wave-guide Tweeter and Angled Woofer
  • Frameless round and square grilles


Pinpoint Accuracy, Dispersion and Lifelike Imaging are all featured
THE CS AIC 860 features many of PSB’s core technologies with design by Paul Barton the design of the CS AIC860 minimizes the amount of refraction common to many angled speakers which can often “give away” the position of the speaker. With the new PSB design , the listener experiences a wide and consistent sound field which seems to emanate from the chosen listening area rather than from the installation point. So with proper dispersion and tuning, true 3-dimensional lifelike imaging is attainable.

The premium 6.5” woofer of the AIC 860 utilizes a carbon-filled polypropylene cone, for both stiffness and light weight. This woofer includes trickle-down technology that PSB has developed for its flagship Imagine Series to get higher sensitivity, bass extension and lower harmonic distortion at high playback levels. High frequencies are capably handled by a 1” titanium tweeter with Wave Guide and indexed adjustment for precise adjustment of the tweeter’s acoustic axis. Also included are acoustic adjustments for the mid/woofer and tweeter level for additional tuning to the room or listener location.

For maximum visual appeal, the CS AIC 860 features frameless magnetic grilles with invisible scrims for a seamless visual appearance. Both round and square grilles are provided, adding design flexibility while simplifying inventory requirements. Installation is easy and predictable with the improved, simple, foolproof mounting system, using heavy duty doglegs. Cutting templates are included. Optional Pre-construction brackets and back cans are also available.

Like all PSB speakers, final voicing is performed by Founder and Chief Designer, Paul Barton, at Canada’s famed National Research Council. PSB’s research has discovered how listener preferences can be integrated into a wide range of speaker designs for many different applications, yet all featuring consistent sound quality that is natural and lifelike.
