Our passive 15″ sub is powered by a master 2-channel Hamrammr Sub 15 Active.
A magnetic front grille is included.
The sub is only 30cm deep, making it a perfect fit for baffle wall installations. The detachable rubber feet make it feasible as a free-standing sub as well.
Three channels are located on each side and below, allowing for easy cable management as well as the possibility of running hidden cables beneath the sub.
The cabinet is made out in thick, 25mm birch plywood to provide a maximum stiffness and rigidity.
