Clear glass speakers promise wireless clear sound

“Serac” Greensound speakers

I am sure some of our glass experts will provide a correction if this claim is wrong, but Greensound Technology has unveiled a line of high-end speakers that they claim is the world’s first wireless, high-fidelity glass speakers and subwoofers, and I have to admit they look pretty cool.

The company is keeping some of the technology that makes the system work close to its chest. When I talked to one of their reps earlier this week, they didn’t want to reveal much about the glass composition or how the drivers that transfer the sound vibration to the glass work. Here is all they are willing to say at this time:

… recent improvements have been made to bring the frequency response from low 150HZ to high 18KHZ frequency responses … The speakers are capable of delivering sound from both sides of the surface of the glass at 360 degree delivering a rich harmonic sound from low to high frequency responses up to 90.6 db. Generally it would seem impossible to be able to hear a low frequency sound from glass, however we were able to achieve a good harmonic sound from low to high frequency responses with our patented approach that is implemented in the base platform of the Serac and Floe speakers to create a combination of low and high frequency sound transferred to the surface of the glass which delivers separated sound from bottom to the top of the glass on both sides of the glass corresponding with low and high frequencies.

Greensound offers their systems in several speaker/subwoofer combinations and each comes with a Yamaha receiver the has the audio and video inputs you’d expect.

So if all this looks pretty sweet, here is a warning. I have saved the “bad” news for last. The company provides a hint of what I am referring to:

“Ideal for venues such as:

• Lobbies
• Large Suites
• Mansions
• Ships
• Large Homes”


Anymore, I am kind of cheap when it comes to buying speakers. Maybe having raised kids that like to amp up the volume to the point of no return cured me of thinking the money was a good idea. But, I still have a lot of friends who have made hefty investments in their speaker systems, so maybe they won’t faint when the see the $8,000–$33,000 price tags on the systems.
