The best speaker for a small room...at any price point.

The original Pulsars would be a better fit over the new Pulsa 2 Graphene version in a room tis size. I've had the originals and now have the Grapnenes in an 11.5 x 12 and can't get the bass under control with the Graphenes.       

At one time I was considering the Vivid Kaya 45 for my 12x11x9 room. However, I eliminated that from consideration thinking that the side firing woofers would pose an obstacle to good sound in a small space.

However, I wanted to revisit that logic since I liked the Kaya a lot. I do not think I will be able to do a home demo of the Kaya 45 but I have heard from manufacturer and also a local dealer that it can be placed close to the back wall (good for a small room). 

The sound of the Kaya is fantastic. It is fast, clear, and a bit like the KEF Blade.

Here is a photo of the Kaya 45 next to the Vivid Giya G1.

Anybody want to chime in on their experience with side firing woofers in a small room?

Berlin 1887 is nice for midsized room and could work with a smallish room.

LS3/5(A) perhaps? from Rogers(Chartwell) or Falcon and very tube friendly. (if you have a 16Ohm tap).
Art Dudley has a recent review and there is a posting on a German blog about then too. https://medialux.blog/
you might have to scroll down to find the bit about the speakers. I quite fancy a pair after reading those reviews.Then there are a couple of Wilsons, the Tune Tots and Duettes. You are going to need home demos to sort this one out, taking a punt based on recommendations is not going to find what you’re looking for.
