I've had my Walsh 4's since 1986; they're rated at 4 ohms but they're actually 6 ohms. From all the tech reviews I've read on the Walsh drivers over the years they usually end up being a nominal 6 ohm load and fairly easy to drive. However the Ohm spec on sensitivity has always been somewhat optimistic; my 4's are actually 83 db with all switches in the center position as opposed to the published 89 db, that means 3 times more power required. My vintage Marantz 2325 with 125 wpc sounds good driving the 4's but my NAK PA-7A MKII with 225 wpc sounds great. Bottom line: they love horsepower.
