The Isobarik loudspeaker was originally available in two types: DMS (domestic monitor speaker) an internal passive crossover, whereas PMS had no crossover at all, and instead used an external Active crossover. DMS were discontinued in 1988 due to the introduction of an external passive crossover. This improved passive performance and allowed very easy upgrade to Active.
Each speaker has two of each drive unit fitted – i.e. two bass, two mid and two treble. The second bass unit is hidden inside the cabinet, behind the visible bass unit and this forms the basis for our patented Isobarik equal-pressure bass system. This means that the front speaker behaves as if it is in a much bigger enclosure.
