New sound-over-power-line tech might let you position your passive speakers anywhere you can find a power outlet -- no speaker cables needed.

Imagine being able to place your existing wired speakers anywhere you have a power outlet, instead of running speaker cable through walls, or under carpets. That’s the promise of Audio Cu , a technology developed by Scottsdale, Arizona-based Fasetto .

Using power lines to transmit data isn’t new. Several networking companies like TP-Link make power line networking products that act as alternatives to Ethernet and Wi-Fi. However, solutions focused exclusively on multichannel, multiroom audio have yet to become mainstream. This is likely because of the inherent difficulty of creating fast and robust connections over wiring that was never meant to perform this role.

“Users can now experience high fidelity Dolby-certified Dolby Digital and Dolby Atmos audio through speakers or subwoofers connected across power lines with minimal latency and exceptional sound performance,” said Fasetto founder and CEO Coy Christmas in a press release. “This enables users to place and connect their home audio system through power lines wherever they wish without the hassle of cumbersome speaker wires or worrying about structural and RF interference.

Audio Cu components are simple. A transmitter plugs into a power outlet and a TV or any other device that has an HDMI output, and the receivers plug into power outlets and have standard positive/negative red and black speaker cable terminals for wiring to a speaker.
