Speaker Placement / Acoustic Treatment (Chane Speakers)

I need help with speaker placement. I have Chane speakers. Eventually I will have two Chane A3rx-c speakers in front, one A2rx-c for the center, and four A1rx-c as side surrounds and rear surrounds. Right now, until the A3rx-c comes back in stock, I am using the A1rx-c as my main two speakers in front and only 5.1, so two as surrounds.

Here is the problem, I have read that square rooms are not good acoustically, but that is what I have. My room is 20X20 feet with an 8 foot ceiling. So I need help knowing first, the best placement of all 7 speakers and secondly how to acoustically treat my square room so it counter acts the negative effects the best. There are already two 5x5 foot windows next to each other on one of the walls. All the rest of the walls and ceiling are normal hard drywall. Also, the room is carpeted with a large couch in it and eventually an AV closet/shelf of some sort. That is all the relevant information I can think of, but I am new to this, so if there is more info you need to know to give recommendations, let me know and I will tell you. Thanks!

Speaker placement is easy, just put then as you would any normal 7-channel system. I’d put the couch about 10-12 ft. back from the screen. I’m no acoustics expert, but it seems to me that your large dimensions would put the speakers some distance from the side walls, which should de-emphasize side reflections more than you’d have with a smaller room. There is some debate and more importantly, research that suggests early reflections are more beneficial than not. Here are a couple of articles you might want to read through:

The worst problems with square rooms tend to be with the low frequencies. They can be dealt with by utilizing two or more subwoofers.
