I have attached a wiring diagram for anyone interested in the IR remote control of the KEF Ci380QT or Ci200.2QT (and likely the CiFDT) motorized speakers. Finding the right hardware and wiring everything correctly took a tremendous amount of time and I wanted to provide this information to save anyone else the hours upon hours it finally took to get what I needed and wire it correctly.
Typically, the KEF motorized speakers are triggered by a 12V output on the receiver OR with the detection of audio output. The auto position is for auto music sense (not recommended for home theater installations due to prolonged silence in most movies) and the manual position is for using a 12V trigger. I wanted to control the motor function by IR remote control. While this is not an inexpensive project, it is possible and the final result is very cool.
KEF MOTORIZED SPEAKERS
 CiFDT (since discontinued by Kef). I did not specifically research the CiFDT motorized speakers but the wiring diagram would almost certainly work for these speakers as well.
 78944 Connecting Block without power plug.
Xantech used to sell the 789-44PS (which included the power plug) but this model number is no longer on their website. If you cannot find the 789-44PS, you can order the 78944 and the 781RG power plug separately.
 CC-12 Remote Relay Module
I originally used a Radio Shack power supply. However after a few years, a hum developed in the speakers that I isolated to the power supply. I even tried placing the power supply on another AC circuit. I replaced it with a Pyramid PS8KX6 6 amp power supply and that resolved the issue. The Pyramid is available from Amazon.com. The higher the rated amps, the more reliable the power supply. Pyramid does offer a 3 amp power supply but it is nearly the same price as the 6 amp.
A run of Cat5 ethernet for each speaker (and traditional speaker wire).
Many learning remotes would likely work well. However, I used a Logitech Harmony Remote and downloaded the IR profile for the Xantech CC-12 from the Logitech database.
Logitech Harmony Remote Controllers
For my home theater, I used the KEF motorized Ci380QT speakers in the ceiling. To wire everything except the speaker cable, I used (3 out of 4-color coded twisted pairs in) CAT5 ethernet wire for each speaker for the 12V DC, Control and 0V in the wiring diagram. If anyone has any questions about this setup, I may be able to help.
The typical disclaimer applies to all information in this post. While this setup worked well for me, I take no responsibility for anyone's equipment or safety and this post is for informational purposes only.
