Leave it to the Aussies to come up with something really cool. The land of the didgeridoo, the boomerang, and Fosters Beer is also the land of the wafer-thin electrostatic computer speaker.
Currently on the crowdfunding site IndieGoGo by IC One Two Pty Ltd., the Expanse Speakers are being made with the gamer crowd in mind with a response range between 250Hz and 20,000Hz. The speaker setup comes in two sizes (small and large) and can be mounted to a TV or a computer monitor. They can also be set up to be free-standing. There is also a 55Hz to 350Hz subwoofer that goes with the left and right speakers. It's not wafer thin like the side speakers, but it's not large either as it measures smaller than 13" deep and less than 7" wide/tall. A 200-watt amp is also part of the package and it's even smaller than the subwoofer. IC One Two says their speaker setup "delivers virtually the entire spectrum of audio detectable by the human ear."
Price-wise, the Expanse Speakers range from an MSRP of $399 for just the subwoofer to $799 for the whole kit'n'kaboodle. Those who back the speakers' IndieGoGo campaign get early bird special pricing.
As for the crowdfunding campaign itself, it's scheduled to run until late June and carries a flexible goal of $60K.
