The Klipsch Custom Series CS-16C II In-Ceiling Speaker delivers clear, dynamic sound from a discreet architectural design that integrates neatly into the ceiling. Built for distributed audio, home theater, and two-channel listening, the CS-16C II combines a 6.5-inch polymer woofer with a 1-inch polymer dome tweeter to provide balanced music reproduction, articulate vocals, and impressive efficiency without occupying valuable floor or shelf space.
Installation is simplified by Klipsch's patented Sky Hook Cinch installation system, which automatically engages the mounting legs as the speaker is inserted into the ceiling cutout. An infinite-baffle design allows the speaker to operate within the ceiling cavity, while the flat, bezel-free magnetic grille provides a clean finished appearance and can be painted to coordinate with the surrounding surface. The result is a versatile architectural speaker well suited to whole-home music systems, discreet home theaters, and everyday listening spaces.
Key Features & Innovations
6.5-inch polymer woofer — the Klipsch Custom Series CS-16C II In-Ceiling Speaker uses a lightweight polymer woofer designed to provide clear, controlled bass and midrange reproduction for music, movies, television, and distributed audio.
1-inch polymer dome tweeter — a dedicated high-frequency driver delivers clean, detailed treble reproduction for vocals, instruments, dialogue, and cinematic effects.
91dB sensitivity — the efficient design allows the CS-16C II to achieve useful output without requiring unusually high amplifier power, making it compatible with a wide range of stereo amplifiers, distributed-audio amplifiers, and AV receivers.
40W RMS / 160W peak power handling — the CS-16C II provides the dynamic capability needed for everyday music listening, whole-home audio, and home theater applications.
57Hz–20kHz frequency response — broad bandwidth provides substantial musical range from a compact in-ceiling design, while a dedicated subwoofer can be added when deeper low-frequency extension is desired.
Patented Sky Hook Cinch installation system — Klipsch's tool-free mounting technology automatically engages the mounting legs when the speaker is inserted into the ceiling opening, significantly simplifying installation.
Preset clamping force — the Sky Hook system applies controlled pressure against the mounting surface, helping create a secure fit while reducing the possibility of overtightening.
Fast architectural installation — Klipsch states that its Sky Hook system can reduce installation time by as much as 75 percent compared with conventional mounting methods.
Infinite-baffle architecture — the speaker is designed to operate within the ceiling cavity without requiring a conventional standalone speaker enclosure.
Bezel-free magnetic grille — the flat magnetic steel grille eliminates the prominent bezel found on many traditional architectural speakers for a cleaner, more contemporary finished appearance.
Paintable white grille — the included grille can be painted to coordinate with the surrounding ceiling, helping the speaker visually disappear into the room.
Versatile system applications — the CS-16C II can be used for distributed and whole-home audio, two-channel listening, or as part of a discreet home theater installation.
Optional installation accessories — Klipsch offers the IK-650-C II installation kit and ME-650-C fire-rated enclosure separately for projects requiring pre-construction mounting or an additional ceiling enclosure.
