MB Quart 980 S specifications

General

Tech nical data

Special features

In the course of the later years of construction, an "SP" version of the loudspeaker was released, which differs from the "S" version by foil instead of wood veneer, which should look a little more modern. 980SP speakers and switches are the same as the 980S 2e version. Advantage of the 980 - SP version: connections on the rear wall.

1e version can be recognized by the *MB* logo on the front and the cover has 6 fastenings (6 pins). The MCD25 tweeter has square dimensions (95x95 mm). It is the same height as it is wide.

2e version can be recognized by the *MBQuart* logo on the front and the cover has 4 fastenings. (2 Pins + 2 Push-in brackets). The serial numbers of the 2e version: 10000 to 15388.

Both 980S versions have the connectors on the bottom. At the beginning of production of version 2, old "MB" logos were still used. The following was true for all versions: if made in real wood veneer, there was always a sticker on the back wall with a note that real wood can change color due to the influence of light. In the course of the production of all 980S series, various changes were made: other chassis series (95-6xxx), cheaper crossover components, rectangular instead of square tweeter front panel, etc. The above technical data may not match "your" 980S. In case of doubt, a request with the serial number of the speakers will help with the service of the MB Quart successor "GermanMAES TRO".
