Woofers de 15” with 4 ohms of impedance, of the professional type, developed to assist to the sound reinforcement needs in situations where smaller impredance provides larger transfer of potency of the amplifier for load (automotive sound), in the range of low and medium frequencies. It is indicated for use in sound truck, sound outside of the car, mobile speaker system, besides conventional applications in night clubs and auditoriums. To reach a high acting degree and reliability, each component of the speaker was projected using advanced technology, and it has the characteristics above: - Voice coil with 100 mm (4”) of diameter, mold in fiberglass and uses copper thread covered with special varnish to support at high temperatures. - Double spider make possible the perfect concentricity of the moving system, providing, like this, great linear excursion even when great displacements are demanded. - The advanced design cast frame is injected in aluminum with great mechanical and structural sturdiness. - The magnet assembly has an extended center polar piece to allow long excursion and low distortion in the bass frequency range. - Metallic connectors, of easy handling and high pressure, guarantee a mechanical and electric contact of high reliability. - The woofer has a cooling system MCS ( Multi Cooling System) that allows a great dissipation of heat from the voice coil, guaranteeing the maximum of efficiency. - Cone and dust cap manufactured with QCF ( t ® Quartz Composi e Fiber), exclusive Selenium technology, improve high resistence to humidity and UV radiation.
