Lautsprecher der D-Lite, Forum, VariLine und
Cobra Familien.

Weitere SL Series Eigenschaften:

• Umfangreiche Schutzschaltungen - Schutz vor
Überhitzung, Überlast, Kurzschluss, Hochfrequenz
und Gleichspannung am Ausgang

• LPN-Filter - zuschaltbare Optimierung von Fre­quenzgang und Einschwingverhalten der Laut­sprecher
