Speaker covers.

You may be thinking of Joseph (Zsolt) who posted as szigony on the wam. He is an upholsterer and made some covers for his harbeths and was thinking of selling them commercially.
Szigony hasn't posted on the wam for a while, however if you contact Alan Shaw at Harbeth , he should have contact details as Jo exhibited his speaker covers at bristol show 2017.

Ah, many thanks Graham, sure he’s the man. Yes. I’ll contact Alan Shaw.

Cool Mark. Please let me know how you go and if Joseph has a website, he mentioned he was going to set one up back in 2017.
