I bought a pair of these speakers and a new Onkyo 5.1 receiver. I have tile floor and two stories so I couldn't do in-wall/in-ceiling without more work than I was willing to put in so I was really attracted to the bi-amp capability of these speakers. I have each speaker hooked up to the front and rear on the left and right and they are amazing. I watched Inception when I first set them up and couldn't believe the clarity and the amount of bass they put out. I looked and listened to other speakers in stores but nothing was close to these in the same price range. Highly recommended!
If you have the space for towers and on a budget, $1K pr. can ROCK you room. Bi-amping is recommended for better cross-over control and tuning. If your amp can perform in a 4ohm load even stereo connection at the amp and bi-wire at the speaker would open up the mid-bass and dynamic range (x-over 80htz.) Feet could be wider and offered to the TFE60 book shelf model. Nicely done. Thank you DCM! (please offer the feet to the TFE60)
