A:Answer Hi,
Thanks for your question. We do not recommend adding any additional speakers to the MAG6.1 system. Adding additional speakers may damage the Sonos amplifier. I would reccomed looking at our Sonance Garden Series system if you need additional speakers. This system is a step up from MAG6.1. Our Garden Series system comes with 8 satellite speakers, a larger subwoofer, and it's expandable up to 16 satellites and 2 subwoofers powered off of a single Sonance amplifier.
I hope you found this information helpful. If you have additional questions, please feel free to call our California-based support team at 949-492-7777 and ask for Tech Support. We are available Monday - Friday, 8 AM to 5 PM PST. We'd love to help you out.
