Any experience with Tannoy loudspeakers?

@islandmandan & @mulveling - for the benefit of the OP could you   provide the dimensions of your rooms please.

The room I auditioned them in was approximately 24ft x 22ft and the speakers were on the 24ft wall

FYI...
The only speaker (which I now own) that came remotely close to the gorgeous Tannoy sound are the "Sonogram" model from Gershman Acoustics. Unfortunately they are no longer made, also being built in Canada, they can be a little difficult to get. Their other models are very good, but there was something about the Sonogram's that drew me into the performance, just like the Tannoys did. The other Gershman models did not really do that.

The only speaker to date that I preferred over the Tannoy are the Avangarde Duo's,  They have a huge sweet spot, massive image and crystal clear delivery, but their price tag is a little bit steep for my wallet.

Hmmm - now I have a much larger listening room - I might just be tempted to try out the Tannoy's again.

Damn - I thought I was done :-)

My Tannoys are situated in a section of my living area room, backed into a little alcove (4 feet deep) that’s 14 feet wide and serves as the front wall for my setup. The length of the room in the other dimension is 21 feet. 10 foot ceilings. However, the left wall is only partial, and the right side opens up into the rest of the main living area - fully 30 feet in that dimension. So there’s effectively a bit more space around Tannoys than there would be in an actual closed 14’x21’x10’ rectangular room. The Canterbury is an excellent size for this space. I used to own Kensington SE, and their bass was a little lean in the same room. And the best bass I heard in this room was from Yorkminster SE, but unfortunately its midrange is not as beautiful as the Canterbury.

The bit of room asymmetry is not ideal, but the building construction is excellent and I’ll easily take a little asymmetry over a flimsy construction with bouncy floor and low ceiling under a drywall shoebox. No residential neighbors around, either, so late night loud listening is my favorite pass-time :) And my seating at midfiend/nearfield-ish, along with Tannoy’s controlled dispersion, largely mitigates the asymmetry effects. Sounds amazing! Total immersion into the musical performance, with good records. 

The 12” driver with traditional reflex porting, like the discontinued Yorkminster SE and current GRF 90, will give excellent bass extension - significantly better than the 15” Canterbury. I think that is due to the distributed port on the Canterbury and most other Prestige models - but also I speculate that distributed porting helps given them a sweeter midrange at the expense of bass extension. 

Thinking about this some more, I wonder if @islandmandan ’s custom build, with reflex porting and a large vintage Tannoy HPD driver, would achieve a nice balance of bass extension plus sweet midrange. Especially paired with the right tube amp, which it seems he’s also done. And good god Dan - your custom cabinets are beyond gorgeous! Brilliant work.
