Thanks for the charts GM. Those are pretty useful.
I'm gonna have to read up on your ripole systems, tubelectron! They are pretty close to what I'm trying to achieve looks wise.
mattstat, I'm using the 2 full range speakers so I only need the 1 speaker per box. The characteristics are just a bonus. The full range speakers will be for the mid to upper, and the 2 other boxes will have subs for the bass. The system will be used just about anywhere for everything. Listening to music from all kinds of sources from records to FLAC to MP3 and streaming; Watching TV and movies; listening to audiobooks and podcasts. Whatever so long as they are good for it. We have other speakers too, some klipsch bookshelf units, some DML experiments, and so on.
The design criteria of 16x16x12 is because we have 24 other cubes. These cubes are just the 2 sides, top and bottom. The front and back are open. We move a lot and the cubes make life so much easier when packing, moving, unpacking, and trying to make anything fit in a new space. Cubes can be arranged in any number of ways so thats why I want the speakers to match the rest of the cubes I already have. Cubes everything.
They will be "free standing". Sub on the ground and the FR speakers on top of that probably. They will likely be position near the other cubes if not touching sides. Almost always the cubes are a few inches fromt he wal, but who knows. The "shelving" around them are cubes with the same dimensions that act as stools, shelves, TV stand, book shelves, and so on.

Just for fun I made this too.
Maybe I'll give it a shot, worst case scenario I rip all that stuff out and shrink the internal volume and do a traditional port. I need to find some calculation for filling and how much that reduces the t-line length. Right now its set to 86.56 in.

Oh this is wonderful. Thanks GM.
tubelectron, do you mean the "t-line" design above? I didn't actually plan to build that. I figured it would be a nightmare to make, and probably not deliver. Just a fun idea. As of right now I think my sub will be sealed, while the FR speaker will possibly be ported out of the back. I think the back walls of my boxes will be moved in to match the sizing needed. Like this.
Yes. That's it.
You are right !
This paper about the interest of filling enclosures written by Tom Nousaine is absolutely true - this point is also mentioned by experts like V.Dickason, M.Colloms and J.D'Appolito in their respective books.
The sole point of importance in the case of a BR is to manage a "free channel" (not necessarily direct sight) from the back of the woofer to the port - I mean : no plugging of some sort...
Here's an example on my 222L bookshelf speakers, @90dB/w/m, offering F3=40Hz thanks to filling, with dimensions HxWxD : 370x250x280mm only.

My box size is just weird. If I make it sealed, the box is too small for the FR speakers, if I port it, then its way to big, and I end up with the design above. I don't know if I can fill it enough to make the sealed box work, and even then I keep reading that filling a sealed box is kind of silly.
