How to polish Wilson Audio speaker

jmvs has offered the best solution. When buying used speakers, if the speakers were not cleaned properly (not using micro-fiber cloth to dust or clean) swirl marks may be present. To remove these, I have used Meguiar's Swirl Remover with light application, followed up with Meguiar's Ultimate Polish. The Quik Detailer is great in between waxing....just like your car.

This is an older thread, but I am sure that someone looks up this type of information every so often. Just like I did the other day. And would like to thank everyone for their suggestions. 

I recently got a pair of WATT Puppies 7, with light scratches on top. Moreover, while the general appearance was fine, the finish has - most probably - never been maintained.
Followed the advice in this thread and would like to confirm that the following worked for me, with great results!
- removed scratches using Meguiar's Ultimate Compound (applied, worked it in and wiped clean 3 times) 
- polished to a beautiful mirror look using Meguiar's Ultimate Polish.

Consulted with Maguire's over chat and confirmed that no waxing is necessary since the speakers are not exposed to the elements. And waxing will not protect from scratches. 

Based on other recommendations, will also get an Ultimate Quick Detailer to keep handy. 

I am in no way associated with Meguiar's, just reporting on what worked for me.  

Call Wilson that would be the smartest idea.

After your happy with polishing I would use Mequiars Ultimate Liquid Car Wax. Absolutely non abrasive and will make dusting easier for a very extended period. 

I’ve spent thousands of hours polishing cars...
Novus plastic polish #2 works well to remove swirls and # 1 works well to polish. These have less chemicals than meguirs etc. and in my oppinion are better to use on speakers where you want to takecare around drivers.

Griots Speed shine is my go to, to maintain a nice reflective surface.  Remember than any dust will make swirls so wipe it off carefully with a damp cloth before doing any polishing.

For cleaning drivers, again a lightly damp cloth, no chemicals, no rubbing alcohol, and be gentle.  A soft paint brush works well also.
