RCF højttalerenhed LF18X451 18" Keramisk

RCF 18" Ceramic Woofer 1800W, 3600W program, 4,5"

LF18X451 tilbyder lineær frekvensrespons og high-power-handling. LF18X451 benytter fiber-loaded cone sammen med en high-excursion triple-roll geometry-surround. Denne kombination leverer en maksimal peak to peak excursion på 54 mm. Det nye dual-forced hyper-venting-system garanterer en effektiv voice-coil-ventilation for minimal power-kompression og power-handling.
