Description
The NB3 Series of woofers offer a slim line depth for working well under and behind truck seats as well as other tight spaces. The 12” version, for example, is only 3.375” deep. These are designed to optimally perform in extremely small enclosures and in most truck prefab enclosures. Housed inside of a rugged metal basket, you will find an oversized 80 Ounce ferrite magnet that uses a 3.0" voice coil with the ability to withstand temperatures up to 500f and has a FEA designed center pole vent for removing the heat btu’s from the motor and voice coil gap. The spiders are made of a high-quality Cotton and Nomex blend with stitched in flat tinsel leads. This woofer is a work horse and really shines in small, sealed or ported enclosures.
