Hey Anthony,
Your project is going on track (and looks like a very good track)!
Just a reminder about the room acoustics. You are talking about bass frequencies which are as dependent to the room as the speaker! Before installing your speakers into your room, calculate the nodes and the amount of absorption you need to cover the room from the dimensions of your room and use specific acoustic treatment for that. An appropriate rt60 and a balanced room response creates a very nice listening. Even though this is a horn system, you will be still listening to your room and not just the horns.
Treat the problematic bass regions first, this means all the corners you can cover. You can also build a front wall or a back wall diffuser or both from Tim Perry's plans. Remember the distance from the diffusers are very important for even response. So the depth you choose for your wells in your diffusers will dictate the frequency they will cover and the minimum distance they have to be from the listener. Then install your speakers, remeasure and then address your problems again, starting with the first reflection points. When you have the specific place for your speakers, the first and the second reflection points will be known. I suggest treating not only walls, but also the ceiling in the first and second reflection points. Remember this is not a recording room but a listening environment, so you are aiming to get closer to a non-environment room (not completely)
Here are the links for diffusers and absorbers, I suggest you to build

I can also share my diffuser/absorber panels plans but they are for my specific room, you can however use the idea.
