Energy speakers-price point/value, big box store brand popular with home theater fans.
Relative to price, you get a decent speaker. Especially when you can get them on sale.
Not worth exerting audio neurosis over. Get them if they're in your price range- you don't like them, sell them.
I had a pair of the bookshelf years ago-very nice, especially since I found them 1/2 @ Best Buy as a closeout of the line.
