How Can I Upgrade to Atmos Without Running Wires for Additional Speakers?
A Along with buying a new receiver, upgrading your system for Dolby Atmos will entail one of two things: adding in-ceiling height speakers, or adding Atmos-enabled speakers to the front and rear of your current system. A wireless speaker solution might sound good in theory, but the reality is that there aren’t any good options available for Atmos setups. Also, wireless speakers still require a power cable, which essentially defeats the whole wireless notion.
Since you can’t easily run new wires, I’d recommend going the Atmos-enabled speaker route. Atmos-enabled speaker modules, which are available from companies like Def Tech, Atlantic Technology, Pioneer, and Onkyo, are designed with angled drivers that bounce sound off the ceiling to convey overhead effects in Atmos-encoded soundtracks. Such modules can either be placed on top of or near your current speakers. And you don’t have to worry about compromised performance since Dolby strongly recommends this solution for those who, like yourself, are unable or unwilling to retrofit their home theater with in-ceiling speakers.
