Hey every body. I'm new to the forum here and while I have never posted anything I have gotten some good tips from here on audio set ups. OK so here it goes my friend has 2 subwoofers for sale and they are both good. He has the Klipsch RW-10D and a Polk DSW Pro 660. Price is no option for me on this matter and originally I was gonna go for the Polk but now I'm not so sure since the klipsch sounds amazing as well. Any input or guidance would be greatly appreciated.
