This project has been on the back burner for 3 years!
I finally got a good paint finish, and after color sanding/buffing, I got the nice piano black finish I wanted to match my X-LS Encores. I stored the finished box away in a closet, and lost interest. I spent most of my spare time building and playing around with chip amps, and didn't have much interest in home theater as I was mostly listening to 2 channel music.
When this post came up: http://www.audiocircle.com/index.php?topic=153347.0
I decided it might be time to finish the speaker, and help out someone trying to unload some unused items. I got the drivers and rear terminal cup installed without issue. I was concerned about damaging the gloss finish while drilling 20 screw holes The only issue I had was the need to deepen the counterbore recess for the tweeter which had been built up with multiple coats of finish. I used a carbide scraper to carefully remove several layers of finish so the tweeter would be flush with the front baffle. This was another delicate operation using a sharp tool close to a gloss finish which could have been a disaster with one slip of hand.
Anyway, all is well, and I thought it best to finalize the build thread even though it took 3 years to finish!
The speaker matches my X-LS Encores both visually, and sonically http://www.audiocircle.com/index.php?topic=108371.msg1114394#msg1114394
