The greatest movie performers don’t always have the greatest stature. Think Al Pacino and Mel Gibson for starters. Perfect for smaller viewing areas, the compact HTM4 Diamond centre-channel speaker will seamlessly balance the sound in an 800 Series Diamond home theatre set-up, thanks to highly advanced, complementary technology like a Kevlar® bass/midrange driver and – for the first time ever – a diamond dome tweeter unit.
When you want cinema sound in a less-than-cinema-sized room, the HTM4 Diamond is the perfect centre channel speaker for smaller home theatre set ups, thanks to a neat space-saving design and combined bass/midrange driver.
Accurate high frequencies are important in the centre channel. Uniquely for a speaker of its size, the HTM4 Diamond incorporates a diamond dome tweeter - helping to make sure that speech and dialogue are as clear and well-defined as possible.
