RCF højttalerenhed LF18N405 18" Neodymium 1500W

RCF højttalerenhed LF18N405 18" Neodymium 1500W

LF18N405 er en bashøjttaler med forlænget lavfrekvens som tilbyder kraftfulde og præcise basfrekvenser, med lav forvrængning, lav kraftkompression og en meget høj SPL. Enheden benytter en fiber-loaded cone. Det ventilerede, magnetiske struktursystem tilbyder en effektiv voice-coil ventilation til minimering af kraftkompressionen.
