IMO, this design is an even better match for those subs (given the same color scheme). This one is finished in a matte black and charcoal leatherette. I displayed both of these N3 designs and one of my GR/Rythmik subs at RMAF last year. It was a lot of fun!
This is a picture of the same pair you posted, but it shows the detail a little better.
Do you mind me posting this stuff in your thread?
