Your tweeter will be destroyed unless you use a crossover to keep bottom end out of it. Just like any other two way speaker - your home stereo speakers for example. You look at your tweeter, decide what the lowest frequency you want out of it might be, then buy or build a crossover for that frequency and the driver impedance. You would still run the woofers full range in most bass cabs, adding in the tweeter for sparkle.
Parts Express sells crossovers and parts. You can buy ready made crossovers. You can buy bare boards to add your own parts to. They have charts so you can look up the part values you need for whatever you plan to achieve. And they sell the parts.
