Thanks to some of you who actually had a point.
To answer a few questions, no I don't own this speaker ,no I have not heard this particular sub, if I had I would not have asked for reasons why 505 had such negative comments. I'm trying to find out whether for a mid level system this would be a good deal, this is not going to be my dream set up. Evidently not a sole who responded has actually even heard the sub in action! The thought that all Polk subs stink might be true but if you have not heard this one why open your mouth.
I was actually under the impression that those in the past who ragged on it actually heard it, my mistake.
As for "bedpan" I mean "bandphan" you must of mistaken "Sheepman" for me in that lame reply!!
Again thanks to the few of you who are real.
