Review on Fluance XL8S Reference High Performance 2-Way Bookshelf and Surround Sound Speakers for Immersive Home Theater or Stereo Listening - Black Ash/Pair by David Robinson

The lack of bass in these bookshelf speakers is why I wouldn't recommend them for a 2 channel system. I've been able to use them with a subwoofer, which is better suited to a 2-channel system and delivers significantly improved bass, as well as better soundstage and depth. I'd say if you have a small room and an amp with tone controls you can adjust the bass and get good results, but in medium to large rooms I don't think these speakers will cut it.
