15 women worried magnets will steal earrings at their sound system rave

Hi community Together with 14 other women in Portugal, we built a soundsytem that has a 15'' C2-D. It's been a 3-year project thatis finally almost completed and we'll soon present it to our group of friends and supporters with a party for 200-300 people. And we're wondering -- is it safe to leave the kickbins open i.e. with the driver exposed like this during this 2-day long party? We are thinking that (1) the power of the magnet might pull a phone or someone's earrings if they stand too close and (2) there is a lot of current passing through those connectors that are accessible, should someone less careful want to touch the driver or the connectors.... are these concerns valid? If so, do you think we need to protect them with grids, or a cloth / macramé piece, something that hides a bit the drivers would suffice? Thank you ❤
