- Sonos Sub (Gen 3) wireless subwoofer measures 389 × 158 × 402 mm (15.3 × 6.2 × 15.8 in) according to Sonos; size as Sonos lists it for Sub (Gen 3): height × width × depth = 389 × 158 × 402 mm.
- Sonos lists the Sub (Gen 3) as 389 × 158 × 402 mm (height × width × depth); the Sub 4 guide lists the same 389/402/158 mm figures with the 158 mm value as depth, so the 158 mm side is the slim dimension.
- The file is a plain bounding box at the published size: the rounded square frame and central opening are not modelled.
- True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
