When upgrading my speaker system, I decided to pick these speakers up as my surrounds (two pairs). I have the DCM TFE200 tower mains and TFE center speaker. Matched with a good audio system, this seems like a very competant system for movies and music. These speakers are tone matched with the TFE line, and I was more concerned with having the ability to switch between dipole/bipole for surround. My LFE is a DIY 12" TC Sounds subwoofer (ported and with a true 500W amp). I find that sound transitions are pretty seemless in 7.1 or 5.1 tracks, and the included mounting hardware makes setup very easy. I gave this 4 instead of 5 stars because the cabinet has an active tweeter on both sides, but it has an active mid/woofer driver on one side (where the bipole switch is) and a passive radiator on the other side. With the shape of the speaker, I notice that there's enough pressure for the passive radiator to displace enough air though. Thought I would note that, though
