Gain essential depth clearance and secure your marine audio investment with the Clarion 7.70 CMSP-771RGB-SWG 1″ marine boat speaker spacer rings with King Starboard. Custom-cut specifically for the Clarion 7.7-inch CMSP-771RGB-SWG speaker series, this spacer pair adds a full 1 inch of extra back-spacing to prevent rear speaker magnets from colliding with tight hull structures, bulkheads, or internal wiring.

Precision CNC-milled in the USA from genuine high-density King Starboard, these mounting rings are built to endure harsh open-water conditions, resisting intense UV exposure, saltwater spray, humidity, and fading without cracking or absorbing moisture. Designed with accurate bolt-circle dimensions and smooth edge profiling, this heavy-duty spacer pair provides a flush, vibration-dampened seal that enhances audio clarity while delivering a sleek, factory-style finish across your console, gunnels, or deck walls.

Key Features

• Custom Clarion 7.7″ Precision Fit: Tailor-milled to align with the frame dimensions and bolt pattern of Clarion CMSP-771RGB-SWG speakers.

• 100% Genuine King Starboard Polymer: High-density marine material that will never rot, swell, peel, or warp under sun and water.

• Full 1-Inch Clearance Extension: Solves back-spacing restrictions in shallow compartments, gunnels, and center consoles.

• Vibration-Dampening Baffle: Rigid construction minimizes panel flex and resonance to deliver cleaner, punchier sound.

• Custom Color & Edge Profiles: Available in marine white or black with selectable edge profiles for a seamless, integrated look.

Custom Clarion CMSP-771RGB-SWG Compatibility

Engineered around the exact frame profile and screw-hole configuration of the 7.7-inch Clarion CMSP-771RGB-SWG driver, these spacer rings ensure a flush, snug fit. The precise inner cutout accommodates the speaker chassis without modification, ensuring full perimeter sealing and preventing acoustic energy loss around the baffle.

Marine-Grade King Starboard Durability

Built from genuine UV-stabilized King Starboard, these 1-inch adapter rings are manufactured specifically for harsh marine environments. Unlike standard wood or lower-grade plastic spacers that warp, rot, or degrade, this high-performance polymer remains completely unaffected by continuous salt spray, high humidity, and direct sunlight.

Eliminates Shallow Depth Restrictions

Upgrading to high-output 7.7-inch marine speakers often leads to clearance issues against interior fiberglass panels or electrical runs. By extending the speaker forward by a full inch, these adapter rings grant the back-spacing necessary to mount deep-magnet speakers smoothly into shallow cavities.

Structural Support & Resonance Reduction

Powerful marine speakers produce intense mid-bass energy that can cause thin fiberglass surfaces to rattle and flex. The solid, dense 1-inch King Starboard structure serves as a firm isolation barrier, dampening unwanted panel vibrations and anchoring your speaker securely for tight, accurate sound output.
