So I would say I am still a novice...and I have come to this conclusion through a lot of practice. Basically at this point I think I have a good understanding of speakers/acoustics but as with most my EE skills are deplorable at best.
I used a stock dayton crossover for my first project, they aren't bad but not what I want really want. I put a lpad on the tweeter and actually ended up changing out the vifa tweeter for a dayton silk dome.
I was looking at active crossovers so I could tune (with in room response) the speakers to my liking then build a passive based on those values but this talks to a bigger disconnect.
I have no clue about speaker measurement enough to know what type of db slope, 1st, 2nd, 3rd order L/R, Butterworth, Bisquick freakin crossover I actually need. Because of this I actually had a hard time picking drivers as well. If I am going to make the next step I need to understand this and I think if I go with SpeakerWorkshop/Soundeasy/HOLMImpulse or any of these types of software it won't matter because I won't know the output I am getting or the results won't mean anything to me.
So...to understand the 12d/b 18d/b slopes and the correct type of crossover to choose for a given design and to properly use the acoustic measurement software where should I start that is easy to understand?
Also I want real measurements, not so much simulations. I want to setup a mic in a room or in a car and be able to tune the speakers as best possible. I almost pulled the trigger on the OmniMic last night but I wanted to ask you guys to see if that would even be worth it if I didn't have the theory behind it.

If you want to have some people help you learn about speaker design, then this is probably not the best forum. I can suggest that you start hanging around the Parts-Express Tech-Talk forum:
Techtalk Speaker Building, Audio, Video Discussion Forum
There are some DIY resources that you can read about measurements and crossover design that I host on my web site:
audio.claub.net: software
This is a very good read by Jeff Bagby about doing accurate measurements yourself:

You are at the beginning of a long learning curve that most of us are still one to one extent or another, but luckily you can have a lot of fun and make some good speakers along the way.

You shouldn't believe people such Lynn Olson and others 😛
They're always talking about freakin' levels of volume playing
to very delicate devices 😀
1st order might be ok for starting, since you get a little closer with the devices themselves...that's the title of the thread, right ?
You're decision of changing the drivers wasn't following the previous period you wrote, which assumed that you knew that the crossover was wrong !
