The Sonos Certified Refurbished program is key to our sustainability efforts, helping minimize waste and extend the life of our products.
Serviceability
We're designing products that are easier to disassemble so they can be more efficiently repaired and reused.
Circularity
By incorporating recycled materials in new products and refurbishing existing ones, we're amplifying a circular economy.
Recyclability
We're eliminating plastic from our packaging in favor of paper that's responsibly sourced and completely recyclable.
We donate 1% of Certified Refurbished sales to high-impact nonprofits focused on environmental preservation and restoration, including Rainforest Connection.
Every refurbished product undergoes thorough testing to guarantee it's good as new and includes:
The same one-year warranty as a brand new product
All accessories, manuals, and other documentation
Pristine packaging and necessary replacement parts
Amplifiers
Dual Class-D digital amplifiers perfectly tuned to the subwoofer's unique acoustic architecture.
Woofers
Dual 5" x 8" elliptical woofers face inward for a force-canceling effect that virtually eliminates distortion.
Architecture
Ported cabinet enhances bass response.
Frequency Response
As low as 25 Hz
EQ
Audio settings automatically equalize to balance Sub 4 and the paired Sonos speaker(s). Use the Sonos app to adjust bass, treble, and loudness.
