The SD-1 v.2s are serious SQ subs in a very shallow and efficient package. Made the in the USA to the highest possible standards to last for many years to come.

Ideal for shallow truck enclosures at only 4.5" depth! They utilize a single 6" diameter magnet slug to achieve the necessary flux. Behind the cone you will find a progressive roll spider and a special treatment applied to the back of surround and upper lip of the cone to achieve more stability from the surround and to bring the Mms to where it needed to be. The leads are offset out to the sides and slightly raised to eliminate the possibility for slapping and the motor itself has quite a bit of clearance for the coil thanks to a deeply bumped back plate.
