Weather and chemical resistance

This 2″ spa speaker is resistant to rain and splashing, so it suits use around a spa. It is not designed for submersion, so it should not be placed where it can be fully under water.

The speaker is also resistant to the corrosive effects of spa chemicals. Its construction prevents the materials from breaking down after long exposure to the sun, and an integrated gasket seal is included in the design.
