The HTV-412A delivers awesome tone and projection. Standard sized and stackable, these cabinets use heavy-gauge wiring and finger-jointed construction for strength and tone. Rear-mounted jacks allow the cabinet to be used in mono (320W RMS; 4 Ohms or 16 Ohms) or stereo (160W/Channel; 8 Ohms per). Inside, four 12-Inch Celestion 80 Watt loudspeakers give this cabinet its voice. The HTV-412A is an angled (or "top") design; a companion HTV-412B base (or "bottom") cabinet is also available.
