A concern you might consider is that as the carpet drys under the speakers moisture goes into the enclosures from the air...think humidity. This promotes an increase of oxidation on metal parts. The effect is increased where electricity moves across connections. Areas of concern are where wires connect via lugs or plugs not soldered connections. Some speakers connect the drivers to the crossovers with plugs and lugs to make service easier some solder direct. In general you do not want moisture getting into the enclosures. General humidity is normal but this is like putting a pot of water under the speakers...not normal.
Wet carpet under system
I’ve had a situation where the carpet under my system and speakers got soaked from a leak somewhere because of the heavy rain. The components are on a table removed from the floor. But the speakers are on spikes. Is there any danger of shock or other malady that could befall the equipment?
