Blackstar Series One 412PROB Extension Cabinet
The S1-412PROB delivers awesome tone and projection unlike anything in its class. These standard "1960" size cabinets use heavy-gauge wiring and finger-jointed birch-ply construction. The internal baffle design delivers a balanced midrange response. Inside, four 12" Celestion Vintage 30 custom-voiced 8 Ohm speakers give this cabinet its voice. The S1-412PROB can be used in mono (240W RMS; 8 Ohms) or stereo (120W / Channel; 16 Ohms per). The S1-412PROB is a base (or "bottom") design; a companion S1-412PROA angled (or "top") cabinet is also available.
