Looks good, I like the contrasting baffle color! I've always thought that most commercial speakers either look incredibly bland to blend in with every home, or try to "stand out" and look ridiculous. One of my favorite parts of DIY is getting to build things to my own taste, regardless of how "marketable" it would be. So good job - they really fit with the room, while still having some pop.
I've built a few of Zaph's designs and always found them very well thought out. I don't think he's ever designed a bad speaker (at least, he hasn't PUBLISHED a bad speaker). I'm just starting the ZA5 based center channel myself, and looking forward to getting it going with my ZDT3.5 powered mains.
Do you have any acoustic impressions for us? How are they sounding compared to your last speakers?
As for painting, now that you've gotten used to the most important aspect (prep, prep, prep) you should consider getting into sprayed automotive-style urethane paints. An Astro LVLP spray gun can be run on a moderately sized air compressor, and the range of primers and single-stage urethanes available for spraying is incredible. For the same amount of prep time you can get a really impressive finish.
