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.

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.

Voice Coil � Kapton

Until about 1970, all speaker voice coils were wound on paper tubes, which can burn up when they get hot. The voice-coil is the part of the speaker that the output of the amplifier is directly fed to, and they get hot when driven hard. Kapton, which remains stable up to about 725 degrees Fahrenheit, can be made thinner and stronger than paper, and can take way more heat and mechanical stress. It also has excellent dielectric properties.

Boss Audio AR12D 2400 Watts 12-Inch Dual 4-Ohm Voice Coil Subwoofer Review

These subs are rated for 1200 watts each and I put 2 of them on a 1200 watt amplifier and they fried in less than 3 weeks. I even ran them at 1/3 power for a week to break em in. These subs probably can't even handle 300 watts each. Cheap subs but you get what you pay for. They do a lousy job of sustaining a bass note as well.
