Cone – Poly Injection

Polyurethane, categorized as a polymer, is a resilient, flexible and durable manufactured material that can take the place of paint, cotton, rubber, metal or wood in thousands of applications across virtually all fields. It can be hard like fiberglass, squishy upholstery foam that can be protective like varnish, bouncy like rubber, or sticky like glue. In the case of our cones, this material allows for maximum flexibility that produces great sounding speakers lasting a long time.

Voice Coil – Aluminum

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 – Butyl Rubber

Butyl Rubber is a synthetic (man-made) rubber and is valued for its chemical inertness, impermeability to air, and ability to endure or resist exposure to the many types of weather fronts. Butyl rubber has applications from sports equipment to automotive parts, the medical industry, and more. We use them for the surrounds that connect the cone to the basket. Food-grade butyl rubber is used in many chewing gums as the central gum base, which contributes not only the its elasticity but an obstinate, sticky quality. Similarly, the butyl rubber surround in our speakers can take an equivalent amount of abuse without quitting.

Tweeter – Piezo

Piezoelectric tweeters have several advantages over conventional tweeters. They are resistant to overloads that would normally destroy most high frequency drivers and they can be used without a crossover due to their electrical properties. The active element is a piece of polarized material – some parts of the molecule are positively charged, while other parts of the molecule are negatively charged.

    Nice little door speakers. I can’t give it 5 stars because, the wattage is a lie. I’ve got an old school Rockford Fosgate Punch 75wrmsx2 @2 ohm and 37.5wrmsx2 @ 4ohm. This isn’t exactly a powerhouse of an amplifier. The sound shocked me for how little I payed for them. They’ve been in my truck for about 24 hours now so I’ve no clue on the longevity. They are a little larger for mounting than many 6.5″s but, a little drilling and tapping got these mounted tight. Running 8 gauge wire so I don’t know what that…
