Beyma 18P1000Fe - 18" 1000W 8 Ohm
This low frequency transducer is specially designed to withstand real high power (1000 w AES). Beginning with the 4 inch voice coil, it is the result of the combination of the use of high quality materials (high temperature magnet wire and polyimide fibreglass former) and the important improvements we have achieved in the manufacturing process. Moreover, the use of a thick air gap height and a considerable voice coil length assures a good heat dissipation and an unusual X damage (45 mm). Besides, the cone is made of a high strength paper covered with an special treatment that endures the most extremely outdoor conditions. Another typical problem, the lack of retaining spider mechanical properties, has been solved with the use of a dual spider configuration that includes a nomex spider. Furthermore, the application range of this stout loudspeaker spreads from compact bass-reflex cabinets to high -SPL horn-loaded systems.
