That would be news to me, and many others. I’ve got several Tannoy speakers here with "MADE and designed in the UK" stickers slapped all over their cabinets and boxes. Some really nice quality cabinets, too. It’s known that they started farming out the lower-level lines to China a while ago.
Back when I demo'd the TEAC, they were using Tannoy speakers in their listening room. I remarked on how nice the cabinets were finished and that's when I was told about where the finishing was done. This really jogged my memory some and I need to clarify what I was told.
The cabinetry was done at Tannoy but they were shipped to China for finishing as it could be done cheaper and better there. The lessor lines were being assembled there anyway so they had the infrastructure in place and had a great relationship with them. Some time after most everything was done there no matter what the line up.
All the best,
