I've been hesitant to review these speakers too quickly, as I wanted to allow for a break-in period and make fine adjustments to the system, etc. However, I am already so pleased with them, that they can only improve with additional break-in and adjustment!
Pros: The first really positive thing about them is the price. For the quality of these speakers, they are very well priced. I was looking for something besides Bose (I don't hate Bose and have them in other rooms... just wanted something different here), but I didn't want to sacrifice quality or looks. These speakers are beautifully fininished, in a piano black laquer that makes them at home among the finest furnishings, or a dorm room. They are small enough to easily blend in, just about 30% or so larger than a Bose cube. The sound is extremely good. Very crisp and clear. I haven't pushed them hard, but they seem to maintain clarity very well at high volumes. The sound is also rich and full.
Cons: The cons are not enough to diminish the star rating, but just little things that could be improved, or that they prospective buyer should know in order to make an informed choice. - The mounting mechanism could be a little bit better... the speakers accomodate either keyhole style or screw in, but the latter would almost have to be custom fit. The keyhole is a bit tight for the speaker mounts that I have... it works, but takes some tweaking. - The speaker wire connection could stand to be larger to accomodate large gauge wiring. I use two 16 ga. wires in a twisted pair for each connection and they just barely make it... again, not a big drawback, but would be an improvement. - The subwoofer is good, but will not rock the house... not out of the box. However, the adjustments and settings available on the sub allow for you to compensate to meet your needs. You AV receiver likely has additional abilities to adjust the bass as you require. For my needs and my taste, it is fine - but if you want really thundering bass, it might take more adjustment and placement trials to get that.
Overall, very pleased with the Energy speakers, and I would repeat this purchase. I have them employed in a small (12 x 16) home theatre in my basement, and in that environment they sound incredible. A large room, or very high ceiling might be a lot for them to handle. For my "all black" look, they are asthetically perfect. Some others I considered had silver trimming that would have cheapened the look. The gloss black is elegant and goes with anything.
