Perhaps this can help, even though am not discussing the same speaker.
Here are in room measurements of Tannoy XT6Fs and Revel M16s. I was astonished when the Revels I got for a secondary system just BLEW AWAY my Tannoys despite not going down as deep. It was a night and day difference. Back then everyone was raving about Tannoy (this has slowed down a lot--which I guess is because there are more measurements out now). I was fooled not just by the usual con artist salesmen but also reviewers I had respected back then.
Again, they are not the same speakers, but there is clearly a similar FR pattern that is recognizable in the Stereophile measurements. Blue, obviously, is Revel.
Once you hear real speakers those irregularities are impossible to ignore. We are seeing 10dB dips in-room in the most audible frequencies. More, it is clear here and in Amir's measurements that that coaxial driver SUCKS. Here it breaks apart past 10. It just falls apart. These Tannoys certainly were brighter than the Revels, that much is obvious in the measurements, but the worst part about them is that that rollercoaster above 1k sounds sort of like the break-up above 10k. By this I mean that after I finally heard quality speakers the Tannoys sounded like I had a large glass table in front of my listening position, with sound not reaching me in a natural manner. In 2022 they don't cut it. They never kept up with R&D and are relying on antiquated technology that was decent 40 years ago to sell a heritage style. As noted, there has been so much improvement in coaxial tech. None are better than KEF. But this is embarrassing. I expect this from Klipsch at their worst.
And so--as a former Tannoy owner--I really do think that that company SUCKS. That speaker is lovely looking, but you WILL NEVER keep it for long if you take a chance on it.
