RCF højttalerenhed LF21N451 21" Neodymium 1500W

RCF 21" Neo woofer 1500W rms 3000W program 4,5"

LF21N451 er en high-power-handling, effektiv transducer specielt designet til kraftfuld og præcise sub-basfrekvenser, med lav forvrængning og lav power-kompression. Et fuldt optimeret T-pole-design genererer den minimale mængde flux-modulation. Et dual-forced udluftningssystem tilbyder en effektiv voice-coil-ventilation for at minimere power-kompressionen.
