I am thinking of trying out Under Cover waterproof speaker covers for my 4 zx5a and 2 kv2 ex.2.2. Lately i have been finding myself doing a lot more outdoor gigs and want to protect them just incase of bad weather. I would shut them down but, just incase i cant get to the power fast enough, I think it might be worth trying for additional protection. Has anyone used them for powered speakers? I have seen them used in passive speakers but not powered.
