I have some questions for you my good man. Do you know what kind of crossover slope this speaker has?(6db per ocatave, 12,24??)

I know it is possible to replace the woofers(I bought the last 4 they had in stock in the Radio shack warehouse), is it possible to replace the mids and tweeters? Besides the scew terminal versus the spring clips, and the amount of screws on the L-pad, what other differences are there between the 4024's and the 4029's. Once you replace the woofers on the 4029's with a 4024 woofer, what sonic differences are there? Is there any way to remove the dispersion "vanes" on the midrange horn? So many questions here...
