Full size powerful speaker - FRS7 W
This speaker has an excellent sound with balanced frequency response and very good highs. Compared to the FRS7S this speaker has a little more depth which results in a longer hub for the membrane creating an even richer sound - if you can afford the height.

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!
