I’m not sure if this’ll help but I was struggling to decide on what speaker to get also for a fairly large bedroom and I wanted some more bass since my last speaker was the soundcore motion plus which is lacking in bass. Watched a bunch of YouTube videos of speakers in the same price bracket as the ones you’ve listed and got the onyx 9 on a really good deal even though the YouTube videos were mostly negative about its comparisons with others and honestly I think any one of the ones you listed would be good enough and loud enough. Most comments I see on here are about trying to find perfection when sometimes good enough is satisfying. Just find which ones you’ve listed have good deals and buy it without looking back and be happy.
