Kinda. DIY kits are just like rebuilding an engine; all the parts are laid out for you, you just gotta put it all together. I don't know if you've ever looked into changing a standard crossplane V8 (like the Mod 4.6) into a flatplane engine, but a lot of the work is theory based which is then applied to a final product. Speaker designing is like that too; you kind'a have to know what you're doing to successfully pull it off.
If you want to design a speaker, to get started, you'll need a
-impedence measuring equipment,
-(free) software called room eq wizard,
-(free) WinISD, you probably alread have,
-not-so-free software to help design crossovers like LspCad,
-Loudspeaker design cookbook.
-You can also get more software about baffle diffraction to help plan out the placement of speaker drivers of the baffle, width of the baffle and what ripple/diffraction issues you'll have.
You'll design a prototype speaker, measure it, come up with a prototype crossover, remeasure, tweak crossover, remeasure, tweak baffle, remeasure, tweak crossover, remeasure, and continue in whatever direction. Maybe you'll change a mid or maybe a tweeter and start all over again. The key is to be patient and understand why you need to make one change or another so that when an anomaly in the frequency response happens, you'll know how to combat it or at least an idea of what to try.
Oh, you'll need a lot of time too.

No prob. That's the route I am going. I am still rocking an older Pioneer VSX-1014. It has preamp outputs that go to an EP2500 which power some Dynamic 4T's. Once I get my main speakers redone (I want curved walls), get 4 more curved wall enclosures built for my subs, and get my room treatments figured out, I will upgrade my AVR. I'm only running 5ch surround (have the other two boxed up right now), so DTS or DD are good enough for me...well till the summer when this semester is over and I can get some enclosures built.
