Micro Precision 3.28 MKII Tweeter The Micro Precision 3.28 MKII is a 28mm coated silk-dome tweeter designed for smooth and detailed high-frequency reproduction. Its lightweight diaphragm, aluminum voice coil, and compact aluminum housing make it suitable for high-quality automotive systems where installation space is limited. Coated Silk Dome The coated silk diaphragm provides a lightweight and naturally damped radiating surface. This helps the 3.28 MKII reproduce high-frequency detail with a smooth tonal character while keeping distortion low throughout its intended operating range. Aluminum Voice Coil The tweeter uses a 28mm aluminum voice coil. Its lightweight construction supports fast diaphragm movement and efficient high-frequency reproduction. With 90dB sensitivity at 2.83V/1m, the 3.28 MKII can produce useful output without requiring excessive amplifier power. Compact Aluminum Housing The MKII version features a full aluminum housing with a protective hexagonal grille and machined 3-Series engraving. Its 42.7mm cutout diameter and 14mm mounting depth allow it to fit into compact factory locations and custom installations.
