I just ordered my Atmos receiver (Onkyo TX-NR676) and now I need a pair of ceiling speakers. Since they are just for effect channels, I'm thinking smallish (5 1/4 - 8") should be fine. Monoprice has new ones for relatively cheap, but I thought maybe I could do better here before I go that route. A pair of B&Ws would be fabulous to try to voice match what I have, but I don't think it is critical for just "height" speakers. Any decent 8 ohm, 2 or 3 way should be fine. Please let me know what you are looking to get rid of. Thanks.
