Dog pissed on speaker
Any suggestions for how to remove dog piss from speaker, including on paper cone? Klipsch Heresy IV. It still has faint smell, and if I can still smell it must be strong to the dog. Dog has stopped peeing there but I’m still concerned he might again, driven by the smell. And if I get rid of the speakers, who would buy it?
