In-wall Subwoofer setup - Polk vs. Monitor

[Torbu]

For a smaller room - about 11-1/2ft x 14 ft. - I am considering an in-wall subwoofer in order to not further clutter the space.

I am trying to decide between the Polk Audio CSW155 and the Monitor Audio IWS-10 subwoofer & IWB-10 backbox. Does anyone have any experience with either one of those?

Also, what would be a suitable amplifier to power either one of those?
I am not an audiophile, so price is more important to me than sound, meaning amplifier should be less than $200. (I am most likely going to end up using the Sony STRDN1080 AV receiver; and in my ideal world, the AV Receiver would have been able to power the passive sub as well, but there does not appear to be such an AV Receiver.)

Have you looked at Triad? All their in-wall subs have sealed enclosures. The company will also paint the grill to match the color on your wall.
