Product Research
Woofers: The poly woofer cones are titanium plated for a high stiffness to mass ratio. The cones are strong, lightweight and resistant to the elements.
Surround Material: The butyl rubber surround has greater internal loss than standard urethane, preventing harmonic distortion at higher frequencies. It more efficiently absorbs edge reflections that can cause audible distortion, resulting in clearer bass performance.
Tweeters: The speakers use Plyethylene semi-dome tweeters. Plyethylene is a UV resistant foam material that gives you reliable performance and smooth high frequency response. The tweeters are adjustable and may be swiveled for optimum imaging.
The manual incorrectly states that the tweeters are Polyethermide. Per Rockford Fosgate, the actual material used is Plyethylene.
