I attended the usual weekly Zoom meeting of my audio club last week and came away with what I think is valuable advice on a speaker that would suit your room perfectly, Here’s the story I heard: a fellow audiophile member had some Danish speakers in for review which he liked very much. When he had finished his review and returned the speakers he was instantly aware that his Harbeth* speakers sounded dull and unmusical in comparison. The difference was so obvious that he immediately decided he had to sell his Harbeths and buy the Danish speakers, which he did. He is very happy with the change and kept emphasizing how much more musical the Danish speakers were. And, interestingly, the Danish speakers cost about half what the Harbeth’s cost. Perhaps that’s because the Danish speakers are sold direct unlike Harbeth speakers which are sold through distributors and audio shops which raises their cost to the consumer. It also turns out that Harbeth speakers are built to a price point and contain el cheapo parts in their crossovers; the Danish speakers have an opposite philosophy in that their speakers are designed with the best parts that will perfect the way they sound. Also the Danish speakers are shipped free all over the world and have a 60 day trial period.
The speakers are Buchardt S400 MKII. They are perfectly suited to your smallish room.
* I’m not absolutely certain of the model no of his Harbeth speakers I think they were 30.2s
