One of the themes that I noticed at the show was problem solving and aiding the retrofit market. And when wiring is removed from the equation, retrofitting not only becomes much easier, it opens up an entirely new world of install opportunities. While not new, SpeakerCraft’s SonicAir is definitely a problem solver, able to simultaneously send speaker-level and line-level signals up to 100 feet, allowing a single system to drive both a pair of speakers and a sub. The receiver includes a 50-watt stereo power amplifier capable of driving most speakers, making it a perfect solution for people looking to add rear speakers to a surround system in a tough-to-add-wires location.
