'''Trivia'''
+
'''Besondere Ausstattungen'''
* XLR input jack at satellites from MKI was intended for later regulation of satellites, but never used.
+
* aktive Bassregelung über Doppelschwingspulen und Blackbox bei MKII (von Swoboda entwickelt)
Nomenclature: The manufacturer designated the combination of subwoofer and satellites with System.X, i.e. System.One for the large system, System.Two for the medium-sized system and System.Three for the small system. The subwoofers were designated with .1, the satellites with .2, i.e. System.One.1 for the large subwoofers and System.Three.2 for the smallest satellites.
+
* aktive Bassregelung über Beschleunigungssensor in unterstem Basschassis bei MKI (von ART lizenziert)
The MK-I version was developed by Mr. Karl-Heinz Fink, the MK-II version was developed by Mr. Manfred Diestertich, now with Audiophysic.
 
The crossover modules of the two versions differ in their practicality in that the modules of the MK I version could be switched off. Thus it was possible to listen in the evening without subwoofer via the satellites in the full range. This is not possible with the MK II. Here you have to reconnect.
 
In the MK II version of the subwoofer electronics there is a jumper that overrides the built-in filter. This means that the woofers of the System.One, -.Two and -.Three versions can be operated universally as subwoofers with an external woofer crossover or via an AV receiver.
