Caldera is a type of massive volcano, and represents the structure of ZMF's innovative new magnet system. The ZMF Caldera incorporates CAMS (Caldera Asymmetrical Magnet Structure), an innovative magnetic structure that is shaped like a volcano/mountain on one side. This shape allows air to naturally spread out, and maintains a slightly asymmetric magnetic force that makes the membrane more nodal, pushing a massive amount of air towards the ear and diffusing it at the same time.  In concert with the also Patent Pending Atrium damping system, the Caldera delivers a linear frequency response, with a massive amount of punch, weight, and the natural tones that ZMF is known for. 

Sonically the Caldera takes a lot of the ideas that started when ZMF was a T50 modding business. It expands on the explosive, easy going sound that the Blackwood and Ori brought to the T50 arena, except with a more refined sound and current day technology.  The sound of the Caldera is BIG, with an adaptable stage like the Atrium, but tremendous weight and control that comes with typical planar magnetic designs. The mid-range and treble stand out because of the ZMF damping systems and airflow of the magnets - more lucid and nimble, reminiscent of a great dynamic headphone.  With reference to the Harman Curve for the midrange 1.5 to 4khz area, the Caldera delivers both clarity and impact. The Caldera is ZMF's best work yet.
