If Harman Kardon’s GLA-55 is not your cup of tea, look at Greensound Technology’s Serac series and Flow series glass speakers. Unlike traditional speaker technology that may simply include a glass enclosure, Greensound’s speaker projects sound through glass and deliver 360-degree sound. A sound generator in the base of the Greensound speakers vibrates the glass to project the sound and different areas of the glass are responsible for producing different frequency sounds – the curved area at the top produces high frequency sounds, the middle produces mid-range sounds, while low frequencies are produced by the area at the bottom near the base.
The Serac series includes the 25-watt SERAC stand alone speaker, the 150-watt BRAVURA subwoofer, IMMER speaker set that includes one two SERACs and one BRAVURA, and the SEMPRE set that includes four SERACs and a BRAVURA.
The Flow series consists of the stand alone FLOE speaker with 25-watt output, the 25-watt FORZA subwoofer and the FRAZIL speaker set.
