These D&B Audiotechnik B2 subwoofers are in perfect working order but have a few scruffs from regular use. These subs always traveled in a protective bag along with a wooden lid to protect the grill (both included). MULTIPLE UNITS AVAILABLE!
 

The B2 subwoofer with its high output bandpass horn design and extremely high SPL is ideal for extended bass requirements. The B2 cabinet is constructed from marine plywood, has an impact resistant paint finish and eight integral steel handles. The front of the subwoofer cabinet is fitted with catches at the sides for securing an optional wooden lid, and mounted on the rear are four heavy duty wheels.
