Like someone mentioned, music is usually the weak link. Klipsch The Fives Powered Speakers are a decent option under budget since they fit narrow stands and handle eARC without glitching... pretty simple setup.

In my experience, everyone gets way too hyped about that Sony Acoustic Center Sync feature. I've tried it on several setups over the years and honestly, the TV speakers usually have a different timbre than the soundbar, which makes voices sound weirdly localized to the screen instead of blending in. If the Sony HT-A5000 5.1.2ch Dolby Atmos Soundbar is gonna hang off the edges of your console, just dont do it. It looks sloppy and ruins the clean look of that Sony BRAVIA XR X90L 65-inch 4K LED TV. Heres a couple direct tips based on what I've seen work best:

• Stick with the Sonos Beam Gen 2 Compact Smart Soundbar for that specific space. It punches way above its weight class and the Sonos eARC implementation is basically the gold standard for not glitching out. You wont feel like its a downgrade once you hear how crisp the dialogue is.
• If you really want to stay in the Sony family but need to save space, look at the Sony HT-A3000 3.1ch Dolby Atmos Soundbar. Its much narrower than the 5000 and fits those tight media consoles perfectly while still giving you the on-screen menu integration. Skip the KEF LSX II LT Wireless Hi-Fi Speakers for a main movie setup. Theyre amazing for music, but without a dedicated center channel, you're gonna be riding the volume remote during movies just to hear what people are saying. Stick to a bar for the living room.

I spent years swapping out gear in my tiny Seattle apartment before I realized that if you care about music at all, most soundbars under a grand are just gonna sound like a bigger version of your TV speakers. I tried the Sonos route and while it's simple, the music usually lacks any real depth or weight tho. If you're worried about dialogue but want that stereo imaging for your WFH music, I'd look at the SVS Prime Wireless Pro Powered Speakers. I ran these for six months and they have this huge, wide soundstage that actually makes movies feel cinematic without needing a center channel. They're compact enough for a narrow console and since they have HDMI eARC built in, your Sony remote will still control the volume just fine. Another dark horse if you want to stay in soundbar territory is the <a href=" https://www.bhphotovideo.com/c/search?Ntt= Sennheiser+AMBEO+Soundbar+Plus&BI=8941&KBID=10361&SID=12345&DFF=d50" target="_blank" rel="nofollow sponsored">Sennheiser AMBEO Soundbar Plus. It's much shorter than the Sony A5000 so it wont hang off your console, and the virtualization tech is miles ahead of anything else I've tested for movies.

• Get a high-quality Zeskit Maya 8K 48Gbps HDMI Cable to avoid the common Sony eARC handshake drops that drive everyone crazy.
• Angle your speakers slightly toward your face to create a phantom center that keeps dialogue locked to the screen. Honestly, those KEFs are pretty but they can feel a bit thin for huge movie soundtracks. The SVS pair has way more grunt for the money, especially if you're worried about hearing the commentary during the big game.

To add to the point above: I really agree about that Sony center sync feature being a total letdown. I tried it once and unfortunately the sound just didnt blend... the TV speakers had this weirdly thin tone that ruined the soundbars depth. Honestly, I was also pretty disappointed with the Sonos Beam's music performance. It sounds okay but feels kinda hollow for a 65 inch setup. Since youre tight on space and need reliability, I'd look at the Bose Smart Soundbar 600 with Dolby Atmos. Bose is usually a bit more conservative with their tech but their dialogue processing is actually super reliable for movies. It fits narrow consoles perfectly without hanging off. I had issues with other brands dropping the eARC connection on my Sony, but Bose usually stays locked in. Maybe pick up a Monoprice 8K Certified Ultra High Speed HDMI Cable too just to be extra safe since Bravias are so picky about cables. It really sucks having to troubleshoot this stuff when you just want to watch the game, but I'm sure you'll find a solid fix!

Yep been there done that. Can confirm everything said above is spot on.
