This speaker is made in Germany by the German manufacturer Visaton, a company that I personally know for more than 30 years. I build my first studio speakers with speakers from Visaton and they lasted for 15 years until I sold them - and they probably perform still today. So it is no surprise, when entering into the garden railroad sounds, I found Visaton again - and they are great!
