I appreciate everyone’s help and not to say that “I know everything” because I don’t. Which is my reason why I am here…
So, I will take all of this forum recommended suggestions (including recommendations from other audio forums) including Parts-Express techs and see what happens.
It seems like you are here only to announce what you intend to do, despite any suggestion offered here.
Today's technology allows you to design speakers that have flat frequency response and sound excellent. It involves a speaker frequency response measuring rig and computer software to make it work. For home use, this didn't exist until about 25 years ago. However it still requires some experience and skill to use it well. It would be a shame to spend good money and hours of labor on DIY speakers without taking advantage of these techniques.
Did you read Crossovers 101? It is only meant as an illustration of how good crossovers can be designed. It isn't a how-to guide. Do you understand the pitfalls that can come with using first order crossover filters? They are easily avoidable.
A large problem with using any online calculator or look-up table to determine the value for a capacitor or inductor, is they assume a fixed value, usually 4 or 8 ohms, for a speaker driver's impedance. In reality, impedance varies with frequency, and must be measured for each driver over the full audio frequency range. The capacitor or inductor values, even for simple first order filters will be quite different if they are estimated using the impedance vs. frequency data from 20 Hz to 20 kHz than if calculated using a fixed value. Which do you think will work better?
You never told us what woofer and mid range drivers you plan on using for those simple and probably ill-suited first order filters. So that leads me, as well as others above, to ask why you posted.
