Honestly if you want immersion without getting a noise complaint, headphones are the way to go. TV speakers are definitely holding that Pro back lol. I've been using the Sony Pulse Elite Wireless Headset and the 3D audio is legit... you can actually hear footsteps behind you which helps a ton in shooters. Plus it fits way under your budget. If you really want a room-filling sound without a massive setup, look at the Sonos Beam Gen 2. It supports Dolby Atmos and handles the PS5 audio processing pretty well without taking up much space. Just keep the night mode on if the neighbors are touchy about bass. Honestly tho, stick to a solid headset for the best 3D audio experience. It's way more immersive than a budget surround system anyway.
