This is going to be so awesome.
can I get a "AMEN"!

Number one is what I'm most worried about though. Bass travels a long way because of long waves, but I don't want there to be any resonance problems from the waves bouncing around on the way out of the tunnel/vent. I don't want the 'tube' (read wood tunnel) to act as a bandpass box.Ok. Just a couple of thoughts.
1.) I'm not a bass expert, I don't think the travel distance will matter but I could be wrong.
2.) The red being the mdf/ply box, you are going to seal the insides of the seams of the box, right? Did I read earlier that you're going to use some sort of vibration dampening between the surfaces of the box and everything else?
Thank you GK. You're one I'd call credible so I'll take your word for it.You will have resonance issues like that. You want the manifold as shallow as possible ie big enough to support the drivers rigidly and that's it. Let the IB work like it's supposed to work. If you want a horn than build that and stick it in the floor or ceiling.
Yep, that's the idea! In my previous post I mentioned having it in the living room- that is what is referred to as an 'outie' (versus the standard 'innie'). It's when you switch the side of the wall the manifold is on. In this case, I would have put the manifold and drivers in the living room, with the bottom being open to the basement. There are sound quality advantages to this as well (on paper) as the sound waves don't have to travel through an opening. Line arrays have this benefit as well. In any case, I'm not doing that.The manifold should just be the opening from the box into the room so I could be concealed with an attractive piece of fabric.
Doesn't have to be anything fancy. I'm just going to make it myself with hinges. A couple layers of ply sandwiched together with sealant between them, followed by the original piece of drywall I cut away, a few hinges, some rubber gasket for around the edge, a lock, call it a day.you can cut a solid core door down from 6'8" to ?.
depends on how it gets framed out wrt to being supportive of surrounding structures.
AND WHAT IS ACTUALLY "NEEDED"
if there is need of aesthetics, maybe make it a "hidden ' door that opens with a touch latch .
using hidden Soss hinges seems a BIT overkill but then again . . .
blends right into the wall . .
