4" 10 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.

Incorporating the latest German 'CURV' cone technology and titanium tweeter dome for clear, powerful sound in the harsh marine environment. 'CURV' technology incorporates a woven fibre composite which is heat pressed to form a lighter and stronger cone. This creates greater sound definition, higher output and greater resistance to the marine environment. Engineered to minimise magnetic interference to navigational equipment.

    Fusion speakers working well

    Just installed the Fusion marine speakers in my boat. Sound great. The installation kit had all the components I needed, including good advice on the best installation arrangements.
