Pushing the boundaries of what is possible on the water, FUSION’s Signature Series marine speakers are designed to provide unparalleled performance even when exposed to the harshest marine conditions.

Combining ‘CURV’ Cone composite technology with a Silk Dome tweeter and fully sealed crossover components, the Sports Industrial Chrome Signature 7.7” Speaker system is a stylish solution for premium on-water listening.

The Sports style Signature Series speakers feature dual-colour diffused LED lighting options that illuminate Striking Blue or Sparkling White, to either set the mood or start the party.

These 7.7" Signature Series speakers can handle up to a thunderous 280 Watt peak power. 

UPDATE: Now with an updated grille and enhanced acoustics to take your audio experience with Signature Series speakers to the next level.
