Free Air REVO subs are recommended primarily for Infinite Baffle (Free Air) applications where a dedicated subwoofer enclosure is not available or practical. 

Both 10" & 12" REVO FA subs are available in White or Black frames (Black frames use metallic grey cones). All REVO FA Subs are available in either single 2 Ohm or single 4 Ohm impedances. 

All REVO 10" & 12" Subwoofers share the same design features:

• Nylas Composite Frame - to withstand extreme environmental use. Designed to accept optional RGB wiring.
• Injection Molded Composite Cone – For durability & low distortion.
• Santoprene Rubber Spider – Much more durable to water & temperature changes than a traditional treated Cotton Spider used by the majority of marine speakers & subwoofers.
• Santoprene Rubber Surround – Offers a superior bond to the composite cone.Also resists deterioration due to water, temperature & ultraviolet exposure. 
• Stainless Steel Terminals – Designed to resist corrosion.

All REVO Subwoofers are sold without grills.8 different grill designs are available separately for all versions of 10" & 12" REVO HP & FA subwoofers.This will enable users to have matching grills on both REVO Coaxial In-Boat speakers & REVO Subwoofers.

Optional RGB LED Kits are available to fit under all REVO 10" & 12" subwoofer grills to enable users to have thousands of LED light display combinations.
