Audison Voce II AVBX 12 D4 II - 12-inch Enclosed Subwoofer with 4+4-Ohm Dual Voice Coil
The Audison Voce II AVBX 12 D4 II is a 12-inch enclosed subwoofer that delivers powerful, deep bass in your vehicle. The 4+4 Ohm dual voice coil allows for flexible wiring, and its power handling of 550 W RMS (1100 W Peak) is suitable for powerful mono amplifiers. A 37 mm high CCAW voice coil on a fiberglass former, a high-density ferrite magnet, and a die-cast aluminum basket ensure stability and control. The polypropylene cone with mica injection and rubber surround operates across a wide frequency range from 25 to 400 Hz. Available at Carhifi.shop.
