Cone Polypropylene is a resilient and durable manufactured material. It allows for maximum flexibility that produces great sounding speakers. | Voice Coil Our speakers are capable of higher or elevated temperature strength and fatigue properties that will increase performance and efficiency of heavy duty play time through lower weight and higher operating temperatures | Surround Impermeable to air, rubber has the ability to endure or resist exposure to the many types of weather fronts. Rubber has many different applications. We use it for the surrounds in a many of our speakers to connect the cone to the basket | Tweeter Dome tweeters have improved sound dispersion and the shape radiates sound with a wider dispersion pattern than the semi-dome design. Since high-frequency sound waves are very directional, a wider dispersion of the sound waves will give you a larger "sweet spot" to work with when setting up your system. |
