Designed for use in compact ported box, the 12W800A is a great choice for any system where high efficiency and high output is the goal. This low frequency midbass has been painstakingly voiced to create a natural tone with low distortion at high levels. Featuring a multi-roll surround, large raised spider, and 2.50″ light-weight voice coil, the 12W800A is capable of high output while keeping distortion under control.
