Product description

8" 2-Way Speaker W/ Flush Mount 1" Titanium Dome Tweeter 

Upgrade your marine or powersports audio system with the Cerwin-Vega SM8F4 2-Way 8" Marine Speaker with Flush Mount 1" Titanium Dome Tweeter, engineered to deliver powerful sound, rugged durability, and modern styling for outdoor environments. Designed for boats, UTVs, ATVs, and other recreational vehicles, these Cerwin-Vega marine speakers provide high-output audio performance while standing up to the harsh conditions of water, sun, and outdoor adventure.

The SM8F4 8-inch 2-way speaker system features a high-performance 8-inch woofer paired with a flush-mounted 1-inch titanium dome tweeter, creating a balanced audio experience with strong midbass, clear midrange, and crisp high frequencies. The titanium dome tweeter ensures precise high-frequency reproduction, allowing your music to cut through wind and engine noise for exceptional clarity while cruising on the water or riding the trails.

Built for demanding environments, the Cerwin-Vega SM8F4 marine speakers feature a high-temperature injection molded composite basket that provides superior strength and heat resistance. The UV-coated waterproof composite paper cone is designed to resist water spray, saltwater exposure, and prolonged sunlight, ensuring reliable performance in marine and outdoor applications.

With 150 watts RMS and 300 watts peak power handling, the SM8F4 speakers deliver dynamic sound output capable of filling open spaces with powerful, distortion-free audio. The ferrite magnet motor structure with Max X-Max suspension enhances bass performance and maintains stability even at higher output levels.

Installation is quick and clean thanks to the flush mount design, allowing the speakers to integrate seamlessly into boats, wake towers, dashboards, or side panels. To enhance visual appeal, the speakers also feature integrated RGB LED lighting, adding customizable illumination that brings style and atmosphere to your marine or outdoor setup.
