Klipsch CS-16C II In-Ceiling Speaker (Each) at Vinyl Sound Toronto Canada

The CS-16C II is a 6.5-inch two-way in-ceiling speaker from Klipsch (Indianapolis, Indiana, USA), available at Vinyl Sound in Toronto, Canada. The entry-level model of the Klipsch Custom Series, the CS-16C II delivers the acoustic design principles of Klipsch's premium architectural and box speaker lines at an accessible price point for distributed audio, whole-house audio systems, home theater, and two-channel stereo installations. It features a 6.5-inch Polymer woofer paired with a 1-inch Polymer Dome tweeter, achieves 91 dB sensitivity, and covers a frequency range of 65 Hz to 20 kHz — all within a tool-free, bezel-free installation package that reduces install time by up to 75 percent.

Good Sound for Any Room

The CS-16C II is built on the same fundamental two-way driver configuration and ABS infinite baffle enclosure approach that Klipsch applies across its entire custom installation range. The 6.5-inch Polymer woofer handles bass and midrange frequencies from 65 Hz upward, covering the full range of music, dialogue, and ambient audio content needed for background listening, distributed multi-room audio, and surround sound use. The 1-inch Polymer Dome tweeter takes over at the crossover point and reproduces treble frequencies through to 20 kHz. The result is a speaker that performs above its Custom Series entry-level positioning, delivering clear, dynamic, and balanced Klipsch sound in rooms of small to medium size where a straightforward, no-frills in-ceiling solution is needed.

6.5-Inch Polymer Woofer

The Polymer cone woofer in the CS-16C II is chosen for the same reasons Klipsch uses Polymer and Polypropylene cones across its wider speaker lineup: the material is stiff without being brittle, lightweight without sacrificing structural integrity, and moisture-resistant enough to perform consistently in kitchens, bathrooms, laundry rooms, and covered outdoor spaces where cellulose-based cones would degrade over time. The 6.5-inch cone diameter makes the CS-16C II well-suited to rooms up to medium size, providing adequate bass presence for music and television audio when the speaker is crossed over to a subwoofer at 80 Hz to 100 Hz for home theater applications. At 40W RMS continuous power handling with a 160W peak rating, the CS-16C II pairs with a wide range of multi-zone amplifiers and AV receivers used in residential distributed audio systems.

Patented SkyHook Tool-Free Installation System

The CS-16C II uses Klipsch's Sky Hook Cinch by Swarm installation system, a patented tool-free mounting mechanism shared across the entire Klipsch Custom and Designer Series. When the speaker body is inserted into a 7.99-inch cutout, the internal dog legs engage automatically at a factory-preset clamping force, locking the speaker securely to the ceiling surface without any tools. The preset torque eliminates the risk of overtorquing and cracking the ceiling material, which is a common hazard with manually tightened conventional dog-leg systems. For ceiling surfaces that are not perfectly flat, a quarter-turn adjustment of each dog-leg screw achieves a flush, level finish. At just 3.91 inches mounting depth and 5.1 lbs total weight, the CS-16C II is the lightest and shallowest model in the Klipsch 6.5-inch in-ceiling range, making it particularly easy to handle and position during installation in confined ceiling spaces.

Key Features

• 6.5-Inch Polymer Woofer: A stiff, lightweight, moisture-resistant polymer cone delivers clean bass and midrange response from 65 Hz upward, suited to music, home theater, and distributed audio in small to medium rooms.
• 1-Inch Polymer Dome Tweeter: A polymer diaphragm handles high-frequency reproduction with smooth, consistent output and long-term durability in variable humidity and temperature environments typical of residential in-ceiling installations.
• 91 dB Sensitivity: High efficiency means the CS-16C II delivers strong output from modest amplifier power, a practical advantage in multi-zone whole-house audio systems where power is shared across many speaker positions connected by long wire runs.
• 65 Hz to 20 kHz Frequency Range: Covers the full range of audible content from upper bass through treble, providing balanced, full-sounding audio for background music, television, and general home audio use without a separate subwoofer in smaller spaces.
• Patented SkyHook Tool-Free Installation: The Cinch by Swarm mechanism auto-engages at a factory-preset clamping force on insertion into the ceiling cutout, preventing overtorquing and reducing installation time by up to 75 percent versus manual dog-leg systems.
• Bezel-Free Magnetic Grille: A powder-coated magnetic steel grille attaches flush to the ceiling with no visible bezel ring, creating a seamless, discreet appearance. The grille is paintable to match any ceiling color.
• Shallow 3.91-Inch Mounting Depth: The shallowest mounting depth in the Klipsch 6.5-inch in-ceiling range, making the CS-16C II compatible with ceiling spaces where mechanical services or shallow joist bays limit available rear depth.
• 40W RMS / 160W Peak Power Handling: Compatible with standard multi-zone amplifiers, AV receivers, and residential distributed audio systems used in whole-house and background audio applications.

Frequently Asked Questions

What is the Klipsch CS-16C II?

The Klipsch CS-16C II is a 6.5-inch two-way in-ceiling speaker from the Klipsch Custom Series, featuring a Polymer woofer and a 1-inch Polymer Dome tweeter. It delivers 91 dB sensitivity, handles 40W RMS, and covers 65 Hz to 20 kHz, making it the entry-level model in the Klipsch in-ceiling range and the straightforward, cost-effective choice for distributed whole-house audio, background music systems, home theater surround positions, and two-channel stereo listening in small to medium rooms.

What is the difference between the Klipsch CS-16C II and the DS-160C?

The CS-16C II and DS-160C share the same 6.5-inch format, SkyHook installation system, and bezel-free magnetic grille, but differ in tweeter technology. The DS-160C uses a 1-inch Silk Dome tweeter mated to Klipsch's proprietary Tractrix® horn, which increases efficiency, controls dispersion more precisely into a 100-degree pattern, and reduces high-frequency distortion compared to the bare Polymer Dome tweeter in the CS-16C II. The DS-160C's horn loading also contributes to its wider frequency extension down to 77 Hz versus the CS-16C II's 65 Hz. For budget-driven multi-room audio builds where horn performance is not a priority, the CS-16C II is the practical choice. Where sound quality, efficiency, and controlled dispersion matter, the DS-160C or DS-160CDT are the stronger options.

How does the Klipsch CS-16C II compare to the Polk Audio RC60i or similar budget in-ceiling speakers?

The Klipsch CS-16C II and the Polk Audio RC60i occupy a similar budget in-ceiling price tier, but the CS-16C II holds an advantage in sensitivity at 91 dB versus the RC60i's 89 dB. This 2 dB difference means the CS-16C II produces noticeably more output from the same amplifier power, which matters in multi-zone systems with long speaker wire runs that reduce power delivery. The SkyHook tool-free installation system also reduces installation time compared to the RC60i's manual dog-leg screw system, making the CS-16C II the more efficient choice for installers fitting multiple speakers across a whole-house audio system.

Can the Klipsch CS-16C II be used for home theater surround sound?

Yes, the CS-16C II is suitable for in-ceiling surround sound use in a home theater system, particularly for side surround and rear surround channel positions. Its 91 dB sensitivity and 65 Hz to 20 kHz frequency range cover the full content of surround channels, and when crossed over to a subwoofer at 80 Hz or 100 Hz as recommended by Dolby and DTS guidelines, it handles ambient sound, effects, and dialogue with clarity. For Dolby Atmos height channel positions where on-axis delivery to the listening seat is important, the DS-160CDT with its adjustable CDT aiming mechanism provides better directional control from off-center ceiling positions.

How does the SkyHook installation system work on the CS-16C II?

The SkyHook system uses a patented Cinch by Swarm mechanism where the speaker body is pushed into a 7.99-inch cutout hole and the internal dog legs engage automatically at a factory-preset clamping force. No screwdriver or drill is required for the primary mounting action. The preset torque prevents overtightening, which is the most common cause of drywall damage during in-ceiling speaker installation. For ceiling surfaces that are not perfectly level, a quarter-turn of each dog-leg screw fine-tunes the fit for a flush, seamless finish. The overall mounting depth of 3.91 inches is the shallowest in the Klipsch 6.5-inch in-ceiling lineup, and the 5.1-pound weight makes single-person overhead installation straightforward.

Where can I buy the Klipsch CS-16C II in Toronto or Canada?

The Klipsch CS-16C II is available at Vinyl Sound, an authorised Klipsch dealer in Toronto, Canada. Vinyl Sound carries the complete Klipsch Custom Series and Designer Series in-ceiling speaker range and can assist with system planning, amplifier pairing, and accessory recommendations including the IK-650-C II installation kit and the ME-650-C fire-rated enclosure for code-compliant residential and commercial builds across the Greater Toronto Area and beyond.

Is the Klipsch CS-16C II sold individually or as a pair?

The CS-16C II is sold individually as a single speaker unit. For stereo listening in a room, two units are required. For whole-house distributed audio or multi-room background music systems, the number of speakers depends on the zone layout, room dimensions, and coverage requirements of the installation plan.

Does the Klipsch CS-16C II need a fire-rated enclosure?

The CS-16C II is an infinite baffle design that does not require a dedicated back box for standard drywall ceiling installations. The optional ME-650-C fire-rated enclosure is available separately for projects where local building codes require fire separation between floors or occupied rooms. The optional IK-650-C II installation kit, which includes a mud ring, breakaway wire tie, and color-coded mounting brackets, is also available separately for professional custom integration builds that require structured code-compliant framing around the speaker opening.
