The HTM61 is the larger of the two centre speakers in the 600 Series, and is tailor-made to partner either of the two floorstanding main speakers (the 683 or 684) in a commanding home theatre system.

It’s an impressive piece of equipment in itself: a full, three-way speaker comprising a 165mm diameter Kevlar® bass/midrange, a 150mm diameter Kevlar® midrange with FST cone surround technology, and a Nautilus™ tube-loaded tweeter. It doesn’t have to be laid horizontal beneath the screen, as is the custom with centre speakers. If space is lacking, stand it upright. Either way, the HTM61 is cut out for centre stage.
