Cable Matters 7.1 Speaker Wall Plate with HDMI

Cable Matters Triple Gang 7.1 speaker wall plate consolidates HDMI, seven gold-plated binding posts, and a subwoofer RCA pass-through into a single low-profile faceplate for tidy, in-wall home theater installs.

If you want a neat, professional-looking A/V wall connection that supports 7.1 surround sound plus a UHD source, this Cable Matters triple gang plate offers labeled binding posts, an HDMI 4K@120Hz passthrough, and an RCA subwoofer port. It fits a standard triple-gang opening or low-voltage bracket, comes with mounting screws, and ships as a three-piece kit so you can route cables through the wall and finish the installation with a clean faceplate.

How does this plate simplify setting up a 7.1 surround system?

The plate replaces multiple loose terminals with one organized hub that clearly identifies front, center, and rear channels. Color-coded rings and printed labels reduce wiring mistakes and let you connect banana plugs, spade lugs, or bare 12–18 AWG speaker wire quickly.

• Seven screw-type gold-plated binding posts for reliable speaker contacts
• Red/black rings on both front and rear for fast polarity checks
• Supports banana plugs, spades, or bare wire to match common speaker leads

What video and audio formats does the HDMI port support?

The built-in HDMI passthrough supports modern video resolutions and higher refresh rates for game consoles and UHD sources. Audio passthrough preserves multichannel streams so your receiver can decode Dolby and DTS formats natively.

• Video: up to 3840x2160@120Hz and 2560x1440@240Hz
• Legacy/resolution flexibility: 1920x1080@500Hz and common refresh rates
• Audio pass-thru for DTS-HD Master Audio, Dolby TrueHD, and other multichannel formats

Can I connect a subwoofer behind the wall with this plate?

Yes. A dedicated female RCA coupler lets you route a subwoofer cable through the wall so the sub can plug in behind the plate and the visible area stays tidy. This is useful for future receiver upgrades and hides the low-frequency cabling from view.

• RCA subwoofer female coupler for concealed connection
• Keeps in-wall cabling accessible yet out of sight for a clean installation
• Compatible with powered subwoofers using standard RCA patch cables

What hardware and measurements come with the faceplate?

The low-profile faceplate is sized to fit common triple-gang openings and includes the inserts and mounting screws needed for a straightforward install. Its compact depth minimizes wall protrusion while giving room for connectors and wiring.

• Overall dimensions: approximately 4.5 x 6.4 x 0.2 inches
• Three-piece kit: faceplate plus two inserts for quick wiring
• Mounting screws included for standard triple-gang or low-voltage brackets

Who is this for: Installers, home theater enthusiasts, and homeowners upgrading from speaker wire terminals or messy wall hookups to a single, labeled, professional-looking connection point. It’s ideal for custom installations that need full 7.1 audio support, modern HDMI video passthrough, and the convenience of banana/spade compatibility — all in a white low-profile faceplate that blends with most walls.
