Hits hard with good amp
iI’m using a cheap 100W subwoofer amplifier between this sub and an old Yamaha 5.1 receiver. Anything less than 100 watts isn’t going to push it hard enough. I’m running this along with 4 small 3way outdoor speakers and sound coverage is great. For best coverage from one of these bury it next to a wall. Price seems high for one 12”sub in a speaker box. But it’s less than most competition.
