Soundbar dimensionsiBar alone in its normal tabletop orientation, without detachable rears, wall brackets or external cables. A source that includes detachable ends must use component_dimensions instead. A size labelled L x W x H, as on Amazon, is width x depth x height.

The 280 mm mark is the spacing of the two wall hook holes. The US page and info sheet say 25.95 x 2.95 x 4.72 in, which would be 659 mm wide. TechRadar also gives 75 x 650 x 120 mm, so the guide is used.
