I don’t know how they sound but the Sony Soutina glass speakers really look awesome.
They feature a transparent organic glass tube which vibrates and expands sound to 360 degrees. A short glance at the specs:
Frequency response of 50Hz – 20,000Hz- Input line, coaxial, and optical connectivity (means active speakers)
- Subwoofer (13cm)
- Medium speaker (7cm)
- Tweeter made of organic glass
Last but not the least, the price hurts (6,500 €)…
