was able to get a quick spl meter measurment in before wife got home.
with meter pointed at sub, approximantely six feet away, similar to this psw505 review http://www.hometheaterhifi.com/volum...er-4-2005.html
The pl-200 was topping out at around 120 db @ 40 hz.
I intend on measuring a greater response when I can, lol
more : 110 db @ 30 hz ( shows minor signs of struggling)
107.5 db @ 20 hz (struggles but quite deep and room shaking )
So far so good, if im measuring this as the psw505 reviewer was, its easily beating the psw505 down. I am not trying to bash or compare this sub to the polk, but was merely using that review as my baseline for measurement.
