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.

The 683 is the largest speaker in the 600 Series. A true three-way floorstander, ideal for both stereo or home theatre applications in larger rooms, where its timeless look allows it to fit into any interior.
The 2½-way 684 floorstander is a great choice for hi-fi or home cinema in medium-sized to large rooms. Its twin Kevlar drive and aluminium dome tweeter make for a refined performance.
