PPC Series PPC112C 1x12 60W Closed-Back Guitar Speaker Cabinet Black. The Orange Amplification PPC112 Compact Closed Back Speaker Cabinet is a 1x12 cab featuring a 60W Celestion Vintage 30 Speaker. Orange speaker cabinets, like their amplifiers, are built to last using extremely rugged construction and manufacturing techniques. Every Power Projection Cabinet (PPC) is built using 13-ply high-density 18mm Baltic Birch plywood. A unique skid feet design helps to acoustically couple their cabinets to the stage, thus providing a tighter bass response and full range tone definition. The result is a laser-focused tone that's full of warm midrange. All Orange guitar cabinets are equipped with comfortable flush handles and the same legendary basket-weave grill cloth.
