Wharfedale Pro Delta 218B Passive Sub

WHARFEDALE DELTA 218B PASSIVE SUB

The Delta 218B uses two high output, low distortion 18” cast frame woofers with 3” voice coils.  

Comprehensive array inserts are marked on the top panel for arrayed applications. Delta 218B is ideal when used in arrays and is equally at home in a wide variety of fixed installation and touring applications. Rhino Rock, our new texturised composite finish is used in all models. This new finish provides the great look of a painted finish with the durability of a carpet covered enclosure giving you the best of both worlds. The Delta 218B is constructed from plywood.
