The Infinity 622MW is a pair of white 6.5-inch marine coaxial speakers designed for boat and outdoor audio installations. They provide a practical upgrade for factory marine speakers that need to handle open-air listening and regular exposure to moisture. The two-way design combines a woofer and tweeter in each speaker for full-range playback from a compact round mounting format.
With 75 watts RMS and 225 watts peak power handling per speaker, the 622MW is suited to marine source units or compatible external amplification. Its 92 dB sensitivity helps it produce useful output without requiring unusually high amplifier power. The 50 Hz to 20 kHz frequency response covers bass, midrange, and treble for everyday on-water listening.
Infinity uses polypropylene Plus One woofer cones to increase cone area relative to conventional designs in this class. Balanced-dome tweeters are used to reproduce upper-frequency detail, while the coaxial layout keeps the system simple to install. This makes the speakers well suited to locations where a separate tweeter mount is not practical.
The 622MW is built for marine use with an IPX5 rating, a polymer basket, rubber surround, and sealed motor structure. Its grille-mounted tweeter allows the front of the woofer cone to be sealed, helping limit water intrusion toward the speaker motor. The white finish and integrated grilles provide a clean appearance for boats and other outdoor installations.
These 4-ohm speakers can be used as direct replacements in compatible 6.5-inch marine speaker openings or as part of a broader system upgrade. Pair them with a marine-rated receiver or amplifier that supplies power within their continuous rating. Mounting hardware, gaskets, screw clips, and documentation are included to support installation.
Key Features
- IPX5 Rating: Supports use in marine environments exposed to water spray.
- 75W RMS Handling: Matches compatible marine receivers and amplifiers.
- Two-Way Coaxial Design: Integrates woofer and tweeter in each speaker.
- Plus One Polypropylene Cone: Provides increased effective cone area for output.
- Balanced-Dome Tweeter: Reproduces detailed high-frequency information from a protected location.
- Sealed Marine Construction: Uses rubber surrounds, polymer basket, and sealed motor structure.
Design & Installation
The 622MW uses a white grille, polypropylene woofer cone, rubber surround, one-piece polymer basket, and sealed magnet motor structure. Its bridge-mounted, grille-mounted tweeter lets the woofer cone be sealed at the front, an arrangement intended to help protect the motor structure from sea spray. The speakers are designed for marine exposure, including sun, salt, and wash-down conditions.
Confirm that the mounting location accommodates the 5-1/16-inch cutout diameter, 2-5/8-inch mounting depth, and 7-1/16-inch outside diameter before installation. Use the included mounting gasket, screw clips, and stainless steel mounting hardware, then connect each speaker to a compatible 4-ohm marine audio channel. For system matching, use amplification rated appropriately for the speakers' 75-watt continuous power handling.
