``Resonating realism'' Balances the depth of the sound and the sense of speed.

The 3.16 MK III Mid Bass features a black anodized aluminum diaphragm, as well as a high-rigidity steel basket, basket, surround, spider, speaker cone, and dust cap that meet EURO-DIN standards. This improves the clarity of the midrange and bass ranges, as well as the core and speed of bass reproduction. It is also compatible with the optional aluminum inner baffle ES-T09AL and waterproof cover ES-FSP-65 (silicon baffle), expanding the range of installation.
