I am thinking i didn't give all the information so here is more
The cavity of the speaker is limited to about 6" deep, 15" wide and anywhere from 40 to 60" tall. These dimensions are because i want it mounted into the wall. So the woofer is 8" and is the CDT-800CF. I was going to do a sealed enclosure because from what i understand the woofer hits 0 db around 200hz if it is not ported. I am not sure what to do about the midrange which is a DS18 PRO-NEO8 8" which i hooked up in a temp system and sound good but I am thinking it is not as high quality as i wanted so i might switch them out. The tweeter is the Dayton Audio AMT3-4 Air Motion Transformer Tweeter 4 Ohm, i know it is not the best tweeter and the AMTPro-4 is better but money is not unlimited. So right now i have already into it $600 dollars for the speakers and 300 for the amp. I still need to build the crossover and speaker box.
So I would like as high fidelity as possible on my budget.
Does this help? Do you have suggestions for a better Midrange woofer?

Between stud spacing is ideally 14.5 inches (a little more or a little less in actual). With 1/2 inch material that leaves an interior depth of 3 inches and a width of 13.5. Use a modeling program to determine the interior volume need for the tuning you need - an in-wall loudspeaker does not need baffle step correction - but you may need to adjust the tuning a bit if the speaker is within a couple feet of a corner and if the Sub is in the likely position near the bottom of the wall. You can use a service - Madisound or Partsexpress to work on your crossovers - or purchase a program such as LEAP. Always best to measure the speakers Thiel-Small parameters. FYI - these are car subwoofers that are optimized to radiate into a small volume - not a room.
(Not real subwoofers with a Fo = 45Hz?)
No worrys though - what ever you do - enjoy the process. you will probably want to crossover the AMT at 2000-2500 - though you will find the AMT, as a large diaphram, mid-range tweeter to be beamy - not much off axis energy above 5kHz

I recommend total newbs buy a kit and AFTER, if they have enjoyed the process, they can purchase a measurement suite and mic and measure the end product and do a sort of "design analysis" of what the kit was about.Doing a three-way design from scratch with zero previous knowledge or study is, well, just a bad idea.
It's like going to a car forum and saying, "Yeah, I know how to change oil. Can you guys help me build a *custom* 400hp engine from scratch and give me a step by step on how to do this?"
Yeah, no.
