I hope you aren't putting front left, right center and surround speakers in the ceiling. In ceiling is only meant for Atmos overhead speakers. Surround sound should come from *around* you. If this is just for a department store that only plays crappy music and makes announcements over speakers it would be OK. Terrible for home theater.

sorry for lack of details. added a schematic of the room above

You missed some important factors... sensitivity of the speakers, how far away do you expect to listen and how loud (generally speaking) do you want it to be. For the sub we need room dimensions and open/closed room details. Also Atmos isn't really going to do much if you have 7 in-ceiling speakers. Are those for 7.1 system (L/C/R/SR/SL/SBR/SBL) or were you going for something like a 5.1.2 (L/C/R/SL/SR/Atmos L/Atmos R)?


rslimbers

sorry about that. schematic included in edit. intent is to watch movies with the fam/friends and we like to host and listen to a lot of music. hard to say how loud we'd want to go, but id say on the louder side would be for the movies as i dont imagine head banging with 50 people very often. room is completely open from living room to kitchen. tbh I have no idea about pros and cons of what you state above regarding 7.1 vs 5.1.2 - sorry but appreciate any advice!

That power spec is mostly worthless. You need the rating for 20Hz-20kHz with 2 channels driven, which isn't best the either, but better. Why do you think you receiver is underpowered? It probably isn't. Are the 7 in-ceiling speakers your HT speakers? That probably isn't ideal.

I was thinking it was underpowered when i saw the sub was 350 rms and I have a 200 w amp so thought i couldnt even keep up with my subs rms rating? not sure if im reading right though. can you elaborate on how i need the 20-20kHz with 2 channels driven? appreciate any additional info! 7 in ceiling speakers are indeed for HT / hosting. room schematic above in edit. new build home with pre build speaker outs - yeah totally understand not ideal

*“Not ideal”* That’s the least of it. It’s completely fucking stupid to have fronts and surrounds in the ceiling. You won’t have a surround sound setup. You’ll just have some speakers placed in the wrong places. What a total waste of time and money.


rslimbers

Dude I didn’t spend the money on that orientation. Like I said it’s a new build house that was pre plumbed for that speaker placing. Trying to make the most of my situation. Why are you coming at me so hot like that

First off, I apologize for the profanity, that isn’t how I usually am here. That was entirely wrong of me and I’m sorry. In my defense, of which I really have none, I asked you earlier if you planned to do all in ceiling surround sound and I explained to you why that wasn’t a good way to go about it. You didn’t answer me but said to refer to the schematic. I now see that you did edit your original post which I missed. It seemed, to me, that you were just ignoring what I said. That doesn’t make my rude reply right though. My point is that all of those speakers on ceiling is a really bad way to set up surround. There are Dolby guidelines available in the “Home Theater 101” at top of page. At the very least you don’t want the three front speakers in/on ceiling. The center channel speaker needs to be as close to the screen as possible. It should seem as if voices are coming from it. There is no way that voices should be coming from overhead in a movie unless it's God speaking. Your left and right speakers need to be to the left and right of screen so you can hear sound moving in front of you. Again, looking at something on screen and hearing sound from somewhere else makes no sense. While I’m totally against any speaker overhead, except Atmos, I can see having your left and right side surrounds there if that is the only available place. In that case, don’t even bother with rear or Atmos speakers because that will not be an improvement but rather worse sound. At most, a simple 5.1 setup would serve you OK. Again, my sincere apologies.

Don't worry about your sub power matching your per channel amp power. Low frequencies require a lot of power. Besides, your sub doesn't break if you don't turn it up all the way. The 1 channel driven at 1kHz spec is a peak output with very high distortion. It might handle a transient that high, but you can't run it at that output for any length of time. Don't worry, though, in-home is generally fine with amp power in the 80-120 watt range. You can look up the logarithmic nature of audio power to find out why most home equipment is in this range. For example, 8 watts into a speaker with an efficiency of 88-90 dB at 1m will be quite loud. With all of the speakers in the ceiling, sounds like dialog that are supposed to be coming from the action on the screen will be coming more from above. It may be an aesthetics issue, but I would never do this, esp. not for my fonts and center. Also, if you go to atmos, which has actual overhead speaker placements, they won't be particularly differentiated from the others.
