The MAC-04 is a 4” cast frame midrange/mid bass featuring an attractive anodized aluminum cone with a rubber surround. This driver features a 2 layer 25mm voice coil, flat spider, inverted dust cap, and extended pole piece. The voice coil is vented through the Kapton former, under the spider, and through the back plate.

Parameters are optimized for use in a small vented enclosure or as a dedicated midrange. It features linear response through the passband with minimal breakup for a metal cone driver. The 4 ohm impedance increases sensitivity for use in a small 2-way and offers flexibility in padding options when used as a midrange.
