@arafiq I had a big speaker, Thiel CS3.7’s, in my 12x11x9 office for close to 2 years. It was a fun challenge to make them work in this space. I used various combinations of the following to make it work,
GIK | Convolution filter on ROON | Rearranged furniture | A bookshelf with books behind speakers | Luck
It sounded good but constrained somewhat by the room. Though, I was enjoying it.
Two weeks ago, I moved the Thiel CS3.7’s to my Livingroom since it was finally safe from my son’s destruction to do so. The speakers sounded so much better in this larger space. I actually sold the speakers a few days later because I knew I could get my end game speaker in there since the Thiels worked well. I sold it in 1 day after putting up ad.
I then put my 10-year-old KEF LS50’s + KEF KC62 sub into the small room. This room is treated with GIK panels. The sound was so much better than the Thiels in the office. Conversely, the Thiels was way better than the LS50 + KC62 in the larger Livingroom.
My takeaway was that you can make almost any speaker work in a small room but there is a penalty. With a smaller speaker in the same space there seems to be much less of a penalty. I am getting much greater enjoyment with the smaller speaker in this space. The LS50 does not seem constrained by the room, it seems to fill the room perfectly. I am not recommending the LS50, just a small speaker.
BTW - the Thiel and KEF drivers are similar in that the tweeter and midrange are in one driver unit. So, the dispersion should be similar (but different results in the same room).

I am not sure if it was you that I said this too before, but another choice that is better than the 2 examples that I have mentioned in this post, is the new RAAL SR1a earphones with the RAAL VM-1a tube headphone amp. This is good as anything I have heard, anywhere. It also eliminates the room from the equation. I am listening to it as I write this, and this is end game sound.
