The Artisan 412B delivers awesome tone and projection. Based on the vintage tall-style design, these cabinets use heavy-gauge wiring and finger-jointed birch-ply construction. Rear-mounted controls allow the cabinet to be used in mono (240W RMS; 4 Ohms or 16 Ohms) or stereo (120W / Channel; 8 Ohms per). Inside, four 12" Celestion G12 Vintage 30 loudspeakers give this cabinet its voice. The Artisan 412B is a base (or "bottom") design; a companion Artisan 412A angled (or "top") design is also available. Castors are included.
