75 mm diameter aluminum bobbin and voice coil of edgecopper ribbon is adopted on a 75 mm diameter aluminum bobbin, and it is designed to be placed in a uniform magnetic flux even for high power input, so that uniform linearity and braking force are obtained.
The mid-range is equipped with SM75-150 which is 7.5 cm soft dome type mid-range.
This unit contains a magnetic circuit with a gap length of 5 mm, similar to an ordinary woofer, and an edge-wise copper ribbon voice coil with a winding width of 3.5 mm.
