Sonance - VX42R SINGLE SPEAKER - Visual Experience Series 4" 2-Way In Ceiling Speaker (Each) - Paintable White

Hi, Thank you for your question. Yes, the Sonance VX42R can be installed in a ceiling that contains attic insulation. The speaker is designed for in-ceiling use and can safely contact standard insulation materials such as fiberglass or cellulose. We do offer an optional retrofit backbox that can be installed on the back of the speaker to provide additional protection and ensure consistent acoustic performance when insulation is present. I’ve provided you with a link to the VX4-ENC-R Enclosures below. https://www.bestbuy.com/product/sonance-vx4-encl-r-visual-experience-series-4-round-retro-enclosure-for-4-vx-2-pack-black/J78WL76WCP I hope you found this information helpful. If you have any additional questions, feel free to reach out to our California-based support team at 949-492-7777. We’re available Monday through Friday, 6 a.m. to 5 p.m. PST, and happy to help! – Sonance Tech Support Team
