The 50 mm dome on the HiVi DMB-A dome midrange is a treated artificial fabric coated with special damping material. The resulting sound is airy and light, but very articulate. The high power handling is a result of the under hung voice coil paired with an aluminum former.
With the DMB-A's shielded symmetric double magnet and vented design, the low distortion on this driver is truly pleasing to the ears.
