From what I know the Chinese own Tannoy now, along with Quad, Musical Fidelity and others. Their whole staff left to form Fyne Audio which is apparently now considered a better product and made in the UK, Scotland? Except for their budget line which is made in China.
Tannoy played cat and mouse for several years never confirming where their speakers were made. As you rightly mentioned cabinets were being made in Poland, except for the cheaper models. I don't have a problem with Poland they are an Audiophile nation but they are not Scotland, with decades of experience building Tannoy speakers.
There are massive markdowns on Tannoys at Upscale Audio, probably the Chinese made ones.
I was highly considering buying a pair of Fynes but ultimately went with ATC SCM 100 passive. Although they were more expensive the power handling was far superior and the cabinetry is mirror finished high end veneer, which means one speaker looks like a mirror of the other. Absolutely beautiful. With real heritage too.
