Tandberg - Audio Millennium Tower Speaker set

The Tandberg Audio Millennium Tower speakers are rare, high-end appearances from the later period of the Norwegian brand tandbergista.home.blog. These slim speakers combine elegant, modern Scandinavian design with audiophile sound reproduction. They are known for their very spacious, transparent, and detailed soundscape, with tight control in the bass.

Enclosure: Bass-reflex / Slimline tower design

The speakers perform very well indeed.
