Jealous. I was going to build 2 but I'm running out of room. I'm already building new boxes for my QSC 2150's which will give me an extra 4 feet (wide) behind my screen. Still deciding if I want to hide both PA460 MBM or 4 SI-18" subs with the speakers. Once the weather cooperates I'll start on my subs. Either 2 Maximus v.3 or Tuba HT.
If I decide not to add seating to my riser, that opens up a lot of real estate for boxes. Not sure I need seating for 8 when its only the kids and I. I may actually add a bar area for the and/or adults to eat while a movie is playing. Leaving the seating area on the main floor. Ughh. decisions, decisions.
I'll be watching your build closely. Today its 22 degree, yesterday 68 lol Crazy arse weather..
