4" 120 Watt 2-Way Speakers

FUSION's Full Range Marine Speakers are designed and engineered specifically for the marine environment. FUSION's marine speakers include design innovations and materials that not only produce great sound, but also ensure a sustained high performance level during prolonged exposure to the marine elements. These 4” 2-way speakers have an impressive 120 Watts peak power. 

The Full Range speakers incorporate the latest German 'CURV' Cone Technology and a titanium tweeter dome for clear, powerful sound in the harsh marine environment. 'CURV' Cone Technology incorporates a woven fiber composite which is heat pressed to form a lighter and stronger cone, which creates greater sound definition, higher output and greater resistance to the marine environment. The FR speakers are also engineered to minimize magnetic interference to navigational equipment.

Features:

True-Marine™ designed and engineered – Extensively tested to perform in the harsh marine environment.

IP65 water resistant design - Rated IP65 water resistant and complies with international standards for UV stability and salt/fog resistance. Features a fully sealed cross-over, magnet and tweeter housing with water resistant cone and surround.

Efficient design – Designed to operate efficiently, saving power through reducing battery drain.

Magnetic shielding – Magnetic interference is something that all installers take into consideration when installing marine electronics. FUSION understands this, and has added a bucking magnet at the rear of the speaker motor assembly to reduce interference that can occur with compasses or compass-based electronics*.

*As with the installation of any device with a magnetic field on a vessel, compass accuracy should be checked after installation.

CURV Cone Technology

CURV Cone Technology is an innovative engineering process that has created a superior-performance composite cone that delivers premium audio reproduction. CURV is a tough and abrasion-resistant material that is 30% lighter than mica-filled polypropylene at equal stiffness, matched with superior durability and high resistance to moisture, UV and temperatures. CURV is the only option for the FUSION Full Range speakers.

The True-Marine Standard

As a True-Marine product, the Full Range marine speakers are designed and engineered for the harsh marine environment. Once a product has been subject to rigorous environmental testing and passed our stringent True-Marine approval process, it is awarded the accreditation and recognized with an industry-leading 3 year consumer warranty.

IP65 Water Resistance Rating

Every Full Range marine speaker undergoes extensive environmental testing for ingress protection, ensuring they are prepared for the marine environment. The Full Range series has achieved an industry standard rating of IP65 - this indicates the product's protection against dust and water ingress. You can be confident that your Full Range marine speakers are designed to withstand the harsh marine environment season after season.
