I used to be really into my stereo and TV video and audio. But I have been long pasted by, not keeping up with the industry, just changes too fast.
JBL used to be in 90% of theaters, not sure today, but I think they still have quality speakers.
My son is now big into audio/video, next generation, and he is a big Sonos fan, but they are spendy. You kind of get what you pay for. I was looking for a sound bar about a year ago, same type situation as you, and did a ton of research, and seemed that Samsung had a very good product for the price. Unfortunately, I started reading all the user reviews you can find a Google, and quality of product was not very good for Samsung. Sony and LG are kind of the best middle of the road, but both have very good and very bad products, have to know which one you are buying, do go cheapest. Bose spends a lot of money on advertising, gets a lot of fanfare, but experts knock their actual sound quality. Sennheiser is another high quality bar, higher cost.
I know, a lot of crap information, likely not as useful as I thought. But if I were buying today, I would buy Sonos.
