What problem are you trying to cure?
My experience is that EQ's, DSP's and Active crossovers are fine for PA systems, but tend to destroy things I like in sound reproduction, ie. Imaging, Soundstage and Impact. So, if you wish to use such things, flying in the face of professional speaker designers, what is your goal? What is wrong that you are trying to right? If you just wish to experiment, fine, I get that. Just make sure you do not do anything that can't be reversed inside your speakers. BTW- blown tweeters, mids and woofers are a reality you should expect to deal with. Crossovers protect drivers. Without them, you are on your own to create a protection plan. State your goal, and We can help you proceed.
