Infinity 622MLW 6.5" RGB LED Marine Coaxial Speakers

The Infinity 622MLW is a pair of 6.5-inch two-way marine coaxial speakers designed for boats and other open-air audio installations. Their white finish, integrated grilles, and RGB LED lighting support a clean marine-audio upgrade where both sound and appearance matter. The speakers are rated IPX5 for use in demanding outdoor environments.

These speakers are intended for listeners who need clear, full-range sound in conditions where wind, water, and open-air listening can make ordinary speakers less effective. A polypropylene woofer cone handles the main frequency range, while the balanced-dome tweeter is designed to provide smooth high-frequency output. With a 50Hz–20kHz frequency response, the 622MLW covers bass, vocals, and treble from a compact marine speaker location.

The 622MLW is rated for 75 watts RMS and 225 watts peak power handling, with a 4-ohm nominal impedance and 92dB sensitivity at 2.83V/1m. Those specifications make it suitable for a compatible marine receiver or external amplifier. Its 3.5kHz crossover point directs upper frequencies to the integrated tweeter.

Infinity uses a bridge-mounted, grille-mounted tweeter arrangement that helps seal the front of the woofer cone and reduce the path for water intrusion toward the motor structure. The speaker also uses a sealed motor structure, sealed magnet, rubber surround, and UV-resistant one-piece cast-polymer basket. These construction details are intended for exposure to sun, salt, sea spray, and wash-down conditions.

Integrated RGB LEDs add selectable accent lighting to a marine audio system. The included RGB pigtail harness can be hard-wired for color selection or used with an external lighting controller. Install a pair as a direct marine-speaker replacement or combine multiple pairs with a compatible amplifier, source unit, and optional RGB lighting control setup.

Key Features

• IPX5 Marine Rating: Supports use in wet outdoor marine environments.
• 75W RMS Power Handling: Matches compatible receiver or amplifier power.
• Two-Way Coaxial Design: Combines woofer and tweeter in one speaker.
• RGB LED Lighting: Adds selectable color accent lighting.
• Balanced-Dome Tweeter: Provides smooth, weather-resistant high-frequency reproduction.
• Sealed Marine Construction: Helps protect internal components from exposure.

Design & Installation

The 622MLW has a white marine-speaker design with integrated grille and bridge-mounted tweeter. Its polypropylene cone, rubber surround, UV-resistant cast-polymer basket, sealed magnet, and sealed motor structure are selected for outdoor exposure. The integrated LEDs are wired separately from the audio terminals.

Confirm a 5-1/16-inch mounting cutout and 2-11/16-inch mounting depth before installation. Use the included foam gaskets and stainless-steel mounting hardware, then connect speaker polarity correctly at the audio terminals. For RGB operation, connect the included pigtail harness by the documented hard-wire color scheme or connect it to a compatible external lighting controller.
