The new Diamond Audio H600S system consists of a pair of 6-inch midrange drivers, a pair of high end crossover networks, balanced silk tweeters.
The midrange drivers are in the same proprietary cast aluminium basket they have had since the beginning, but that’s about where the similarities to the originals end. The new cone material is a hollow composite material with very low mass and high rigidity, and is complemented with an all new soft polymer hemispherical dust-cap.
The mass and shape of the cone and dust-cap assembly were carefully and painstakingly selected as a result of hundreds of hours of listening, measurement, and trial and error.
The sound-producing assembly is controlled and supported by a specially designed mechanical suspension with a carefully controlled balance of compliance in the flat progressive spider and the butyl rubber surround. Tinsel leads are woven into the spider to eliminate lead slap issues and increase reliability. Electromotive force comes from a custom made copper voice coil, which is wound on a 1.25-inch Kapton former. The magnetics of the speaker also underwent scrutiny to ensure driver linearity and good sensitivity. The magnetic assembly is a 2.3 pound strontium ferrite assembly, with polished and chromed top and bottom plates. A moulded rubber cover dresses up the edge of the motor assembly.
