Thanks Jay/ Lacro, that is essentially what I am doing only it is two step followed by wax. I sanded with 800/1500/2000 and followed that with Meguiars #2 fine cut (based on a recommendation for use with EM6000). I bought Meguiars Ultimate polish to follow the #2 fine cut , I also picked up a can of Johnsons paste wax to apply after the polish. I used a wool pad on my random orbit sander for the left speaker, I decided to try a random orbit buffer, I picked one up at autozone. The buffer came with microfiber pads, so I will give those a shot.
At the rate I am progressing, I hope to be listening to these sometime the week of the 4th, I am on vacation that week.
