Sure, but that doesn't detract from the fact that they sound great in there.
Course not - nothing in audio is an "absolute truth", and of course personal preference comes into it, but I've heard too many pairs of big Tannoys in too many different rooms over the years, big and small for them clearly sounding better in the latter simply to be just a coincidence, therefore I do believe that there is something intrinsically in their design causing that, not simply just my preference.
The biggest shock in that respect, was how much worse mine sounded in a much bigger room at Scalford [after folk had been nagging me for ages about how much better they'd be in a bigger room that would 'allow them to breahe', lol], compared with what I get at home, and which made me re-evaluate things accordingly.
Even in Ian Walker's place, which I believe you've been to, with his Canterbury's, in a room a big bigger than mine (longer) with a concrete floor, we used to spend ages moving his sofa back and forward trying to convince ourselves that it *should* sound better further back away from the speakers, only later to move it forward again, as it clearly sounded better that way
Yes I know you prefer listening to speakers in a larger room, and with different speakers able to benefit accordingly, I would too... But THAT is the key issue. Even you wouldn't prefer listening that way if your ears clearly told you that the speakers in question sounded worse!
