I wanted to begin by saying Thank you to everyone that has helped me in making my final decision. My middle name really should be Secondguesser. Erich, Bill, Nate, and everyone else who were involved, Thank you. I also wanted to say Thank you to ChopShop1 and John at AE for executing the GB. I was waffling between the SEOS 15/AE TD15M and the SOES 12/AE TD12M. Although I can easily fit the larger design, I don't believe it is necessary in the room it is going to be used in.
I have placed my order for the AE TD12M's already. I was going to wait a few days for Erich to get caught up before I ordered the SEOS 12 and DNA 360. It will be a little while till I receive the drivers from AE, so I want to iron out the details before then. I wanted to start this thread in an attempt to gather information as well as make sure I was on the right track.Total: $778.00

Please let me know if I am missing anything or you have a suggestion.
The plan past that is to order blank front baffles from Erich with the waveguides and cd's. I would rather have the recess for the waveguides cut with the precision I don't have. The woofer recess and slot port is within my skill level. The overall space available for the cabinets is 30" high and 24" in depth and 22" wide. I don't think I will need that much, but it is there if I need it. My next questions are about optimal enclosure volume for the TD12M and tuning. (Note) I currently have a single sealed Titanic 15" on sub duty and have 4- 18" Q's here ready to be built, however have put that build on hold to focus on getting my mains in order. Considering my equipment, I was going to tune to 60Hz. I will have them crossed at 80Hz when the 18"s were in use. Although I will not always have the 18"s fired up. Is this advisable? Has anyone modeled and/or know the optimal enclosure volume for the TD12M?
I like the idea of internally separating the waveguide from the woofer and will plan for that and take it into account when ordering the baffle. I also would like to house the crossover in the upper chamber where the waveguide.cd will be I like how RB's turned out and have linked his build below. I understand he had a limitation on cabinet size due to space constraints but I don't have that constraint, thus me asking if there is a more optimized enclosure.

I also added a link to AV Science Sales 5 (Mike's) to the sources as I have been referencing his build thread a lot.
for 3-26" pre cut baffles from Erich.
because I am a PITA. :P Thank you Erich.
I also forgot to add the cost for the 2 sheets of 3/4" MDF +$65
