I like everything about the Sony ES STR-ZA5000ES, but it only controls one subwoofer even though it has two jacks. I actually have four subwoofers. I read that the Yamaha gives you more control of your subwoofers and allows you to pick "enhanced bass" and also "subwoofer trim". I haven't given up on ATMOS because I've already sank a ton into making my system an 11 channel ATMOS system. I just hope it doesn't get replaced by something like IMAX enhanced. And it's been a long time since I've hooked up a Yamaha. I still have a RX-V3300 in a bedroom for an audio only system. My most recent Yamaha I've owned has been a RX-V2700 and I don't have that one anymore. After Yamaha, I went to NAD but ended up having to many reliability issues. Then I tried a Denon which was awful. Last two receivers have been Sony ES receivers and I have been happy with Sony ES except you can't really adjust the subwoofer settings that much. I hope the Yamaha A3060 is the answer.
About the bass settings. On the Yamaha 3060 receiver, set it up so all the speakers are set to small, set the "Extra Bass" setting to "Off."
You stated you have four subwoofers. There are two outputs on the back. A sub Front output and a sub Back output. Also, there are three settings. On page 134 of the manual; it states there is a Left & Right setting, a Front & Rear setting, and a Monaural X2 setting. I'm not positive, but I think the best setting for four subs would be to hook up two to the Front output and two to the Back output. I'm not sure, but I think there are separate distance settings for the front and rear subs based from what I read on page 62...as long as you let it know you have front and rear subs. If
the receiver does not have a way to set separate distances for the two front and two rear subs, I think it might be best to set the subs on the Monaural X2 settings for each pair of subs. It might be best to ask someone else about the sub settings. In my case, I have two subs, and they will be set in the front (left and right) from only the front output and the setting in my 3060 will be set to Monaural X2 setting.
Unfortunately of the three options to choose from for Atmos speaker type and placement...the best option is in-ceiling speakers. Less than ideal would be speakers placed high on the wall, and the least ideal Atmos setup is using speakers that fire up to bounce audio from the ceiling. The problem with using speakers that fire upwards is there's very limited control as to where the bounced audio is landing, and the audio has to be in a certain area in front of and behind the listener.
Take for example the illustration below. Unless you have a way to aim the up firing speakers to direct the bounced audio as shown below; the setup will be less than ideal.
