Who it fits

Key specs explained for this speaker

Woofer Size: 6.5"

This measurement indicates the diameter of the cone that moves air to produce bass frequencies. A 6.5-inch driver offers a balance between compact installation and usable low-end response. You should compare this size with other in-wall options to gauge how much bass you can expect in your room without needing a separate subwoofer for every channel.

Tweeter Type: 1" Titanium dome compression driver

The titanium dome is a rigid material that reduces distortion at high frequencies. The compression driver design focuses sound waves efficiently, resulting in clearer highs and greater volume capability. When shopping, look for this type if you want crisp dialogue and detailed treble that remains clear even at higher listening levels in a home theater setup.

Speaker Type: In-Wall Speaker

This classification means the unit is designed to fit flush within a drywall or plaster partition. It saves floor and shelf space, blending into your room decor. You should verify your wall cavity depth and width before purchasing to ensure the physical dimensions match your available space, as in-wall units require specific structural preparation for proper installation.

Model: R-5650-S II

This identifier distinguishes the second generation of this specific Klipsch model. The revision number often signals updates to internal components or mounting hardware compared to the original version. You should check this exact model number to ensure compatibility with your existing system or to find the correct installation templates, as specifications can vary between generations of the same product line.

Design and build overview

The Klipsch R-5650-S II features a 6.5-inch Cerametallic woofer and a 1-inch titanium dome compression driver. This driver combination is mounted to a 4-inch square Tractrix Horn. The horn geometry creates a 90° by 60° dispersion pattern. This design choice increases acoustic output while reducing distortion. You get more volume from less power. The horn-loaded tweeter can pivot. This allows you to aim the high frequencies toward your listening position. It ensures clear sound even if the speaker is not directly in front of you.

According to the listing, the physical dimensions are 9.3 inches wide, 14.3 inches high, and 3.8 inches deep. These measurements define the cutout space required for installation. The speaker is designed for in-wall mounting. This layout keeps the cabinet hidden behind drywall. It saves floor space and maintains a clean aesthetic. The finish is white. This color helps the unit blend into standard interior walls. You will not notice the speaker in the room decor.

The model includes treble and midbass attenuation switches. These controls let you adjust the frequency response to match your room acoustics. There is also an IR receiver knock out. This feature allows for remote control functionality if you add a compatible transmitter. The build focuses on integration and acoustic performance. It suits users who want high output without visible hardware. The compact depth ensures it fits into standard wall cavities.

Setup and daily use guide

Installation requires cutting a precise opening in your wall to accommodate the speaker’s physical dimensions. The unit measures 9.3 inches in width, 14.3 inches in height, and 3.8 inches in depth. You must ensure your wall cavity is deep enough to house these components without protruding into the room. The in-wall design allows for a clean integration with your home theater system, keeping wiring concealed.

Once mounted, you can adjust the sound dispersion using the pivoting Tractrix Horn tweeter. This feature lets you aim the 1-inch titanium dome compression driver toward your primary listening position. By rotating the horn, you can optimize the 90° by 60° dispersion pattern for clearer highs, regardless of where you sit. This is useful if your seating arrangement is not directly centered on the speaker.

The speaker includes attenuation switches for treble and midbass. These controls allow you to fine-tune the frequency response to match your room’s acoustics or your personal preference. You can reduce harshness or boost warmth by adjusting these settings. The product also features an IR receiver knock out, which facilitates integration with external control systems. This means you can automate volume or input selection without needing a separate remote for the speaker itself. The horn-loaded technology reduces distortion, ensuring that daily movie watching or music listening remains clear even at higher volumes. You do not need to worry about the 6.5-inch Cerametallic woofer straining during intense action scenes, as the design manages acoustic output efficiently.

Before you buy this in-wall speaker

This Klipsch R-5650-S II is a dedicated in-wall speaker, not a standalone unit. You will need a compatible AV receiver or amplifier to drive it. The pivoting Tractrix horn allows for vertical or horizontal mounting. You must check your wall cavity depth. The unit is 3.8 inches deep. Ensure your drywall is securely mounted to support the weight. The white finish blends with standard walls. You may need a paintable grille for a seamless look. This speaker fits best in a surround sound setup. It complements a center channel and subwoofer. Regular cleaning with a dry cloth maintains the titanium dome. Avoid harsh chemicals. Verify your room size matches the 6.5-inch woofer’s output. Larger rooms may require additional speakers or a subwoofer for balanced bass. This model suits those prioritizing clean aesthetics and clear dialogue.

Check before you buy

• Confirm your wall cavity is at least 3.8 inches deep.
• Verify your amplifier supports the speaker’s impedance and power needs.
• Check if you need a separate paintable grille for aesthetics.
• Ensure the room size matches the 6.5-inch woofer’s capabilities.
• Plan for a center channel and subwoofer for full surround sound.
