okey so im thinking for LCR we go with polk Signature Elite ES35 while these techically are center channels they are simetric in both directions so can be mounted vertically either side of the TV. (can be swapped with Signature Elite ES30 to go a touch cheaper, perhaps using one as the acual center istead of the ES35 might look better too).These will get mounted either side and below the TV. For surrounds i'd go with Signature Elite ES15, or the Micca RB42 if you dont mind trading some looks for cash. These will go on speaker stands behind the coutch, i see you have a sim rig so one speaker would go behind the monitor for that and the other could perhaps be mounted close to the seat back. but you should be able to push them away from the couch.im thinking something like this looks decent https://www.amazon.com/PERLESMITH-Universal-Surround-Bookshelf-Speakers/dp/B081N5Z89Y for subs, dayton audio recently released a decent budget sub, i'd go with the biggest that can fit in the bottom shelf of that rack. https://www.daytonaudio.com/category/270/home-subwoofers Then for the AVR, you dont need anything high end, but i'd like someting with the ability to upgrade with a pair of atmos speakers since i think your space could support them well. so cant go wrong with a Denon AVR-S770H. I'd have this in the shelf, then use a cable raceway between that and the TV to hide the wires.
