Dog pissed on speaker

Seriously here's what you need to do. Get a bowl of warm water and add a tablespoon of Arm & Hammer baking soda, stir it good then dampen a cloth with this solution, ring it out then gently wipe the area where the pee is. This will neutralize the pee (ammonia). The wipe again with clean water. Don't over do it.

Maddening, isn't it. Flipping cats(four)and dogs(three)like to go in the front room where I have my ping pong table. 

Only one person suggest an ozone generator.  Least likely to damage the components. That would eventually break down the uric acid, urea, and other nittrogenous compounds generating the ammoniacal smell after bacteria and enzyme exposure. UV light (germicidal) might work, but don't expose paper to it (no speaker cones) only the box.

Jeez, just replace the driver. Quick search showed OEM driver is under 150 $. I wouldn't think twice.

Actually the suggestion of taking the driver out and putting it outside in sunlight is not bad, it would help break down the urine, albeit it might also help break down the cone. Ozone generator similar idea but it's an open question about how good of an idea that is in your house.  

But if it were my speaker, I'd replace the driver. The thought would drive me nuts regardless of the actual impact or lack thereof.
