Get you a couple pair of 301s, 904s or the like.... I have used my 396 IIs a handful of times already with HPF at 100 hz and double 18" SRX subs to full in the lows with crowds up to 300 or so (in spaces smaller than your venue) and completely rocked the venues with plenty of headroom leftover. Crystal clear with zero strain at volumes plenty would be uncomfortable with....
