Anyone have any feedback about sound quality/pricing for these? I'm in the market for an inexpensive bookshelf. These are display model with slight blemish on one grill. They seemed a little hissy in the highs and had a bit of flat thud on kick drum, but I was only able to demo under non-ideal conditions (speakers on floor, lots of background noise etc).

The review link for Polk speakers isn't currently working and a search of the forums only yielded about 6 posts with any mention. A Google does show rpicing in the $350 range, not sure how current though.
