Upstart home audio company Power Sound Audio’s entry into the internet direct subwoofer arena a few months ago with the PowerX line of subwoofers has been accompanied by lots of speculation and excitement. Their middle model in the PowerX line, the XV15 subwoofer, is a large 15” down firing vented unit weighing in at a substantial 92lbs, with a 500 watt class D BASH amplifier, heavily flared Aero-port, black sand textured finish, heavy duty U.S. made driver and a 5 year comprehensive warranty. Additionally the PowerX line is assembled in the U.S. from U.S. made components with the exception of the amplifier. Somehow the price for the XV15 is held to just $799 and that includes shipping. We found that the XV15 sounded clean, composed and dynamic with music, while possessing extension well below 20Hz in room with plenty of headroom to make its presence felt in a large space on movie night. Even more important than the impressive parts list of the XV15 is the manner in which those parts are tuned to work together in a well rounded finished system. Highly recommended.
