If memory serves, the Acoustic 360 is the folded horn cabinet containing a Cerwin-Vega 18 and the power amp, and the head is the pre amp. These were (are?) quite loud, but difficult to hear well until you're about 30 feet away. There quite literally are no highs to be heard. Also, as I recall, the CV speaker is extremely prone to failure. The variable electronic tuning fork is a hoot. The pre amp has multiple outputs, so I guess if you could figure out the phasing a second cabinet/power amp could be used for some comprehensible stage volume. For kicks, you could turn the cabinet toward a wall and use an EB0 with old flatwounds!
