The TPT-MD12 PRO 12" midbass speaker from Timpano Audio is built like a professional midbass, but has been designed for use in the mobile audio market. With a naturally damped paper cone and dual roll cloth surround, this driver keeps resonances under control for natural response. The 3" voice coil and powerful vented magnet are designed to allow high sensitivity and increased power handling. Due to a Qts of 0.38, this will work perfectly in vented or sealed enclosures.
