Which model Tannoy for my audio room

My dedicated audio room is 12 ft wide x 16 ft long x 7.5 ft high. There are no open walls, one door 36" wide in one corner.
The rear of the speakers would be parallel to the 12 ft wall.
I am interested in hearing from people that have listened to Tannoy's in similar to my room size.
I have (3) 300b amps, 8 watts , 15 watts and 26 watts. The 8 and 16 was are set mono's, the 26 is push/pull.
How big a Tannoy speaker can I use in my room ?
I listen to classical and rock on vinyl.

Any comments are appreciated.

If I listened to everyone who told me, "That speaker is too big for your room," I would have had a much more impoverished audiophile experience.
Late to the party and I see you made a decision but to add.

I have Kensington GR in similar sized room but with higher ceilings and I could not be more impressed. Not only do they sound great but they are beautiful to look at. They do a lot of things right IMO
