Panoramica

SF 8CT SUB di Extron è un subwoofer con montaggio a incasso sul soffitto che fa da complemento alla gamma Extron di altoparlanti da soffitto estendendo la risposta alle basse frequenze in applicazioni audio che richiedono una riproduzione fedele e di alta qualità di musica e contenuti sonori. Certificato plenum e progettato per il montaggio nella struttura del soffitto, SF 8CT SUB si abbina armoniosamente ad altri altoparlanti installati a soffitto nel sistema. Il driver a bassa frequenza da 8" fornisce bassi intensi per una qualità audio eccezionale, anche in sistemi di dimensioni più contenute. Con selezioni del wattaggio ad alta e bassa impedenza e un filtro passa basso integrato, SF 8CT SUB offre la flessibilità necessaria a soddisfare un'ampia gamma di requisiti di sistema.
