Parleur woofer pionner ts

Haut parleur 15" Selenium  15 PW3 SLF en bon état. Le cône est un peu enfoncé mais non percé et cela ne gène en rien son fonctionnement. Professional 15” woofer designed to meet a variety of PA needs for small and medium-sized rooms, with excellent performance in the mid and low frequency ranges.For sound reinforcement in nightclubs, dancing halls, auditoriums, bands and also for studio monitors.Its great efficiency in sound reproduction is due to the excellent combination of the different components:- The light cone manufactured with long fiber pulp together with a surround of impregnated fabric give the array great stability, high yield and low distortion.- The voice coil is made of high temperature wire, wound on ® Kaptonformer.- The epoxy painted reinforced steel frame provides thearray with high mechanical resistance.- The aluminum dust cap guarantees great voice coil heat dissipation.- The use of highly resistant adhesives guarantees optimal cohesion and durability of components.*15PW3-SLF: Product with black dull finished dust cap and without Selenium logo printed on it.
