High-performance Subwoofers, specifically engineered for marine duty

Truly engineered for marine duty.

To ensure long-term performance, all models are designed and built to exceed industry standards for salt-fog and UV exposure. These are salt-water rated products that you can use with confidence.

Outstanding Sound Quality

All models are designed to operate in open-air boat environments, delivering powerful, smooth sound that is several steps beyond common marine speakers. These are not car speakers painted white, they are acoustically engineered for boat installations. Engineered to operate without a dedicated enclosure.

Versatile power requirements

Suitable for use with standard marine head-unit power. Designed to benefit from operation with quality amplification, such as the JL Audio marine amplifiers.

Three great looks to choose from!

Available in two grille styles: “Classic” or “Sport”, both in Gloss White. Sport models are also available in a sleek, all Gunmetal finish.
Allows you to match the look of the speakers to the theme of the boat intrior and the customer’s tastes.

Built-In RGB LED Lighting

Included on this Sport grille model, multi-color LEDs are embedded within each speaker grille to produce vibrant accent lighting.
Choose from seven fixed-wiring lighting colors or connect a lighting controller accessory (sold separately) for adjustable control. (Separate 12V wiring is required to power the illumination.)
For optimal performance, we recommend using the JL Audio MLC-RW (Marine Lighting Controller).
