Überblick

Das Extron SoundField^® XD-Modell SF 3C LP ist ein 76 mm großer Breitbandlautsprecher mit einem 102 mm tiefen Gehäuse aus Verbundmaterial für Brandschutz-Deckeninstallationen. Durch seine geringe Einbautiefe eignet er sich ideal für Deckeninstallationen mit schmalem Zwischenraum, wie z. B. Luftkanäle dicht über der Decke. Der SF 3C LP bietet einen direkten 8 Ω-Verstärkeranschluss und kann für Anwendungen mit 4 Ω-Verstärkern parallel geschaltet werden.
