You have a small room, you need to buy a speaker for a small room that plays big. If you ask a question like what is the best speaker, with 50 people responding, you will get 50 different responses which won’t get you anywhere. I just moved from a 27’ x 15’ room to a 12’ x 16’ room, had to get new speakers because my other speakers were too large.
i can list off many speakers I looked at but I’ll just tell you what I was looking at so you can make up your mind: floorstanding with multiple small woofers, midrange, and a Beryllium or Diamond tweeter. I also put in 2 rel t7x woofers.
Only you can determine which speaker sounds best so I would recommend attending a few audio shows or travel to a couple of dealers to actually listen to speakers.
