HTM4 Diamond
One material sums up our quest for perfection in sound reproduction more than any other. Diamond. It’s the ultimate tweeter material – and the magic ingredient in our flagship 800 Series Diamond. It’s part of the reason why 800 Series speakers have become legendary among professional recording studios and serious sound enthusiasts alike. And now, for the first time, you can hear the incredible precision and clarity of diamond in every speaker in the range. The very best just got even better. And perfection just got even closer.
