Speakers with closest sound of Tannoy KensingtonGR

Dear all,
Just went to a local dealer and heard Tannoy Kensington GR driven by the Airtight amp with EL 34 tube (forgot the name).
I was impressed by the sound but my room can't accommodate its size.

Anybody can advice more compact floor stander speakers with similar sonic signature of Tannoy Kensington GR?

Thanks in advance for any advice
