Sweden
Audio Pro (founded in Sweden, 1978) makes warm, musical, genuinely fun wireless speakers that punch far above their price. What Hi-Fi calls it the best Sonos alternative for price and performance.
The C10 MkII is a five-star, multiple-Award winner and the newer C20 W is a current Award winner. Unlike Sonos, most models add Bluetooth and line-in inputs, and older Addon speakers slot into the same multi-room system.
