Marine Boat 3-Way In Door /Out Door 200 Watt Box Speakers System
Midrange - 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 like upholstery
foam, protective like varnish, bouncy like rubber, or sticky like glue.
In the specific case of our cones, this material allows for maximum
flexibility that produces great sounding speakers lasting you a long,
long time.
Surround - Rubber
Rubber is a synthetic (man made) material and is valued for its
chemical inertness, impermeability to air, and the ability to endure or
resist exposure to the many types of weather fronts. 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. Did you know that most modern chewing gum uses food-grade
rubber as the central gum base, which contributes not only the gum's
elasticity but an obstinate, sticky quality? Just like that chewing gum,
the rubber surround in our speakers can take the equivalent amount of
abuse without quitting on you.
Voice Coil - Aluminum
One of the most abundant elements on earth, aluminum is remarkable
for its low density and for its ability to resist corrosion. It is
nonmagnetic (does not have any magnetic properties) and does not easily
ignite. This solid material has the ability to perform under stress in
both high tension and high compression environments.Aluminum is
relatively soft, making it one of the more ideal materials to use in
voice coils.
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 basically a piece of polarized material (i.e. some parts of the molecule are positively charged, while other parts of the molecule are negatively charged)
