Let’s say you have a nice home theater system in one end of the room and a powered subwoofer in the other. Everything sounds nice until you plug the subwoofer into the AC outlet next to it, and, viola, your system is now humming a new tune. Unfortunately, it’s not humming the tune you wanted it to.

Furman and Panamax have introduced a series of power products under the PFPower name that include the MIW-XT “In Wall Power Management Extender System”, which is a fancy way of saying “custom installed extension cord”. A power cord from the back of your power surge/conditioner device (Panamax or Furman preferred but not required) plugs into the MIW-XT Inlet. The power cord from your subwoofer (or other powered device) plugs into the outlet in the MIW-XT. Your electrician kindly runs the electrical wire from the MIW-XT Inlet to the MIW-XT. Now not only is the hum problem gone, but your subwoofer gets all the protection and conditioning benefits that the rest of your home theater gets from your main power management device. All for $69 (plus electrician’s fees, of course).
