I purchased this set of Energy 5.1 speakers with powered sub and I couldnt be happier. I consider myself a Home Theatre Enthusiast. The speakers seem to be pretty good quality and look great, I like the fact that you can take the dust covers off if you choose. Also you can flush mount to wall or use mounting brakets.The sub sounds really good, deep base that I can actually feel it thumping the floor during movies. The speakers are crisp, clear and sound great.Don't think your buying a generic set of speakers just because they don't say Klisph or Bose. This is really a great product. My AVR is actually a 7.1 so I will order 2 more speakers for my back surrounds.Bottomline is you cant go wrong with this set. 

Question: What is the quality of the speaker?
Answer: speakers are crisp clear and sound great
