Summary: These speakers are excellent. They look clean, were super easy to install, and sound fantastic. Compared to my friend's Polk in-wall system, these are clearly superior. My friend says he'll be ordering these to replace his Polks in his home theater :-) Another friend of mine has Yamahas in his wall, which sound quite good, but these Energy speakers still sound better.
Summary: I have Polk RC in-walls all over my basement connected to a Denon receiver and am very happy with them. I was installing a home theater in my family room and decided to go with these Energy speakers. Wow! These speakers are much cleaner than my Polk RC85s, but with a little less bass. I combined them with a Sony dn1010 receiver, Polk sub and a Def Tech Procenter 1000 to get an awesome 5.1 home theater for under $1000.
Summary: I bought four of these speakers to fill my house with background music. They sound great but lack bass. I will have to back them up with a small subwoofer. I got them on sale and for the price I am happy with them.
