PMC is marking its 20th anniversary with a 20-year warranty on all its passive loudspeakers.

The British manufacturer made the announcement at the Munich High End Show and the offer will be backdated to apply to all speakers bought from 1 January 1st 2011.

PMC designs and makes all its speakers at its factory in Luton, so allowing the company to rigorously test and check all its parts and products.

The company also keeps records of every speaker it makes to ensure that identical parts can be supplied if needs be.

The 20-year warranty applies to all new passive PMC speakers providing they have been registered with PMC.
