Transcript
12PW5A / 15PW5A The PW5 series offers excellent quality of sound with strong bass and high SPL, answering of several requests from street sound enthusiasts. These woofers are available on two versions: 12" and 15". This speaker series gets together a set of optimized that will ensure an excellent performance. Deep and clean bass will be obtained from small enclosures. Its high sensitivity allows that the system installed in the car to deliver high SPL, from affordable amplifiers with RMS power rated from 300W to 350W (4 ohms). The PW5 series present the follow features: - Frame with sturdier design and epoxy paint finishing, which provides the speaker great mechanical resistance and high structural stiffness. - Cone made with long fiber pulp with a special coating, ensuring excellent finishing and low distortion. - Surround ring impregnated with rubber that provides excellent fadigue and humidity resistence.
