I figured I'd start a new thread instead of mooching off of the other threads with my questions... I have started my build for the two Gjallarhorns designed by Ricci - thanks for sharing the plans Josh! I'm building these for my 2700 cu ft living room that we use for watching movies, listening to music, entertaining, etc. Not really a "true" HT because it's the main room of our house and there are several different openings to the room, two windows, sliding glass door, vaulted ceiling, fireplace. The goal is to have this room +10 on WAF by looking like a "normal room," but with ninja-stealth, bone crushing sound coming from the shadows.
I chose the G-horn because it's output of sheer terror down to 15hz, which is as low as I care about, below 15hz doesn't do anything for me. I like to turn it up to 11, and have a history of destroying my drivers because of my generosity toward the volume knob, but also because this living room is difficult to pressurize. These will be placed in the attic, behind the vaulted ceiling and firing through to the room from the front and rear left side corners. As soon as these are finished and tested, demo on the room begins for our remodel, subs get hoisted up to the attic for placement.
So far I have the sheets of BB cut according to the plans and the horn-path drafted to the side panels. Tomorrow I will begin with attaching the first couple of panels with PL, also using the Kreg system and screws.
Here is the vaulted ceiling. After bracing and prepping the ceiling structure, the middle gets ripped out, subs go in, one goes to each corner.
Some other shots around the space. Layout will be the same after the remodel is complete
