90RT vs Mc80 or Rc80 ceiling speakers

Anyone have either of these setup in a 5.1 or 7.1 setup? Wondering if any appreciable differences (besides price) between RT series and MC vs Rc80 setups?


  • And by RT series I'm specifically asking about RT70 vs RT90

    I've never used the RT, For my in-ceiling speakers I've used

    RC80i not a bad speaker at least better than nothing
    MC80 good for surround use
    TC80i Good for full range or surround use try's to act like a book shelf speaker. These made going all in-ceiling almost work kind a sorta
    80/FX RT good speaker for surround use. Best I've use for in-ceiling surround and great for ATMOS/DTS-X

  • 90-rt is very nice. Have a pair of them in one of my rooms. Music is nice and full-bodied as ceiling speakers go. Definitely a nice step up over the MC80.

    (RC80 is older model and never had a chance to play with them).

    What is your planned use for them? Atmos? main front? surrounds? If its for your main front channels, i'd say they are definitely worth going with over the lower models. For surround use, can get by with the MC.
  • Yes....I'm looking to add 90RT as L/R front. Will get away with MC's for rears. Also curious if any big differences between RT70 and RT90
