Will second the above...Most manufacturers test their drivers on an IEC baffle which is standardized for frequency response, but the distance of the measurement can vary or not be stated. The scales used can make a big difference in how something looks. A compressed vertical scale will make the driver look flatter, the same data viewed in Vituix will look different because the scale is more equal between horizontal and vertical.
For experimenting and for anyone not well versed in passive crossover design or someone who already has a large stock of passive parts an active crossover is considerably easier to get right, and easily changed if it turns out you made a mistake along the way.
For both reasons (baffle step and flexibility), will second that an active crossover is the way to go. Even if you plan to make the design passive eventually, you will likely save the cost of a minidsp 2x4 in passive parts. If your plan is to go passive in the end, you simply need to consider designing with that in mind (keep it simple, avoid high order filters, no delays, and padding the tweeter.
