Couldn't load pickup availability
This adapter set is designed specifically to allow the Sonos Era 300 speaker to be securely mounted onto compatible Sanus speaker stands originally designed for the Sonos One SL or Play:1. It provides a clean, stable solution for repurposing existing stands without the need to purchase new mounting hardware.
The Sonos Era 300 has a unique shape and mounting requirement that differs from earlier Sonos models. When upgrading from One SL or Play:1 speakers, existing Sanus stands are not directly compatible, which can prevent secure mounting and correct speaker positioning.
This adapter set bridges that gap by providing a precise mechanical interface between the Sonos Era 300 and compatible Sanus stands. It allows the speaker to be mounted securely while maintaining correct alignment and stability, without modifying the speaker or the stand. Installation is straightforward and designed to be completed in minutes using the supplied hardware.
The adapters are designed specifically for the Sonos Era 300, with dimensions and mounting points matched to the speaker’s footprint and the Sanus stand cross-bolt system. A model-specific design ensures secure support and a clean appearance, with no visible mounting hardware from the front once installed.
Speaker stands and room setups can vary. This adapter set is intended for use only with compatible Sanus stands designed for the Sonos One SL or Play:1. The goal is to enable a safe and secure upgrade path while preserving correct speaker placement and aesthetics.
Manufactured using durable, high-quality plastic with a matte finish, the adapters are intended for indoor home use. Matte black and matte white finish options are available to match different speakers and room setups.

How customers fixed their setup
A customer’s TV unit had a raised side panel that prevented proper soundbar placement. Our custom riser stands lifted and centred the Arc without wall mounting.

Excellent customer service. Went back and forth a few times on dimensions and seller was very patient. Item quality is excellent. The width of 40mm lets me run the power, Ethernet and HDMI cables down the back so they are less visible. Fast turnaround from ordering to receiving.
