Outstanding overall quality for the price.
Perfectly finished (real wood).
Excellent trebble and mids, good bass... I use a sub for movies to feel it in my chest and my armchair...but really good enough for music witout a sub.
None yet (3 months using them) they sound better after some use.
I auditioned a pair of B&W 683, and... don't miss them..!
you'll love the Polk RTiA7..!
