These are the new KEF Ci5160RL and Ci3160RL Reference Series in-wall speakers which are based on the blade series, as are a lot of KEF products. In fact, if you go back in time and kill the guy who invented the bales series, you're going to take out the entire KEF organization because a lot of their speakers are seemingly based around technologies developed in those speakers. These speakers use 6.5-inch midrange drivers with a 1-inch Uni-Q tweeter in the middle, plus four 6-5-inch aluminum magnesium woofers for the Ci5160RL and two for the Ci3160RL.
