The Cal.1H (pronounced "Caliber 1H") is not trying to break new grounds. It's an honest take on Electrodynamic transmission. The Cal.1H employs a 50mm driver with an infilled PET diaphragm. There is enough excursion to produce low-frequencies with ease and linearity without the unnecessary/overbearing side-effects. 
The high-sensitivity of the drivers used in the CAL.1H is an advantage for ones who are wanting to correct the Frequency Response to their liking/compensations. 

The build of the CAL.1H is primarily unibody Aluminium. The Headband is a mixture of Aluminium and Spring Steel with Delrin buffers which ensure clean action against the surfaces to avoid metal on metal fatigue. 
Almost all parts of the CAL.1H are precision machined on CNC Turning and CNC Milling machines.
