Audio Legion MR6F 6.5 Marine Boat Speaker Spacer Rings King Starboard – Heavy-Duty, Precision 1/2″ Extension Adapter Pair

Eliminate mounting depth issues and secure your marine audio system with the Audio Legion MR6F 6.5 marine boat speaker spacer rings King Starboard. Precision-engineered specifically for the Audio Legion MR6F 6.5″ speaker model, this spacer pair provides a critical 1/2-inch of added depth clearance to prevent speaker magnet assemblies from contacting internal hull structures, bulkheads, or electrical wiring.

Custom CNC-milled in the USA from heavy-duty, marine-grade King Starboard polymer, these adapter rings resist UV radiation, moisture, cracking, and saltwater exposure without absorbing water or swelling. With an 8.00-inch outside diameter, a 5.75-inch inner cutout, and a smooth 1/8-inch rounded edge profile, these rings provide a sturdy, flush-fitting foundation that elevates sound performance and enhances the look of your boat’s interior.

Key Features

• Custom Audio Legion MR6F Fit: Milled to match the exact dimensions (8.00″ Outer Diameter / 5.75″ Inner Cutout) of Audio Legion MR6F 6.5″ speakers.

• 100% Marine-Grade King Starboard: Crafted from high-density, UV-stabilized polymer that will not rot, swell, peel, or delaminate.

• 1/2″ Depth Extension: Provides vital back-spacing clearance for smooth speaker installation in tight marine spaces.

• Vibration-Dampening Build: Reduces fiberglass panel vibration and resonance for cleaner, clearer mid-range audio output.

• Factory-Quality Edge Finish: Features a smooth 1/8″ rounded edge profile and marine-white finish for a clean, integrated appearance.

Precision Audio Legion MR6F Compatibility

Custom-machined to match the precise specifications of the Audio Legion MR6F 6.5″ driver, these spacer rings feature an exact 5.75″ cutout diameter and an expanded 8.00″ outer frame. This tailored fit guarantees seamless alignment with the speaker’s frame and mounting points, ensuring a tight, secure seal against the mounting surface without requiring extra custom fabrication.

Marine-Grade King Starboard Construction

Manufactured from genuine King Starboard polymer, these spacer rings are built specifically to handle demanding marine environments. Unlike standard wood or soft plastic adapters that absorb water, rot, or degrade under direct sunlight, King Starboard remains completely impervious to moisture, salt spray, and extreme temperatures year after year.

Solves Mounting Depth Clearance Issues

Installing high-output 6.5″ marine speakers often results in clearance issues against tight fiberglass walls, shallow gunnels, or internal wiring. Providing a reliable 1/2-inch thickness, these adapter rings extend the driver forward just enough to ensure ample back-spacing, preventing damage to internal boat structures and speaker magnets.

Vibration Reduction & Structural Support

Operating powerful speakers at elevated volume levels can cause thin marine paneling to flex and rattle. The dense, rigid structure of 1/2-inch King Starboard reinforces the surrounding mounting area, dampening unwanted panel vibrations and creating a solid baffle that delivers clearer audio and tighter sound projection.
