Yes indeed,they were made by ITT in Germany,but the spec is better than the standard telly speakers.You can buy a speaker unit that will fit,and in fact looks very much like the original,for about half the B&O price.I was dissapointed with the sound though!
The original drivers together with the special sound tubes they fit into,give the telly that distinctive good sound.Great little telly's too!
