"These iconic speakers can be used worldwide, regardless of voltage. Regarded by many as the most powerful and finest home speakers ever produced, they were created to celebrate Bang & Olufsen's 90th anniversary. After listening to just one track, you'll realize that nothing else compares. It's like having a concert hall in the comfort of your home! The design complements the sound quality—subtle, elegant, and understated. These speakers have only been used as display models in our showroom.
