IP ratings refer to the rank of protection given by a casing, against solids and liquids. In the format of IPXX, 'X' represents a number The first value of the IP rating represents protection against solids such as dust, followed by the one that refers to resistance against liquids (sweat).
Scoring IPX5, the Boult Audio Z40's rating for solids indicates that no data available to specify a protection rating, and of liquids that they can withstand medium pressure jet that's 6.3mm diameter, similar to garden hose from any angle for 3 minutes at a distance of 2.5 to 3 metres.
