Are those reflex vents or transmission line on the top edge?? Clever place to but them. Nice looking speakers!

The bottom hs a pair of sealed SDX7eN, the midTweeter was an Alpair 7eN in an aperiodic midTL, they suffered a metal cone accident and A7 MAOP are going in. Not the best speaker we have built (but close), but my favorite.
