A:Answer Hi,
Thank you for your question. No, the grilles you are referring to will not fit the Sonos Architectural speakers. I would recommend contacting Sonos Customer Support for replacements. Their support team can be reached at (800) 680-2345. I hope you found this information helpful. If you have additional questions, please call our California-based support team at 949-492-7777 and ask for Tech support. We will be happy to help you out.
