sts9fan - If you're just measuring for fun, then what you listed is fine.
If you're doing any kind of crossover work, then forget about it. You'll need a completely different mic and software (like lspcad). Without an anechoic chamber, it's nearly impossible to design a proper crossover taking impedance, SPL, time, and phase into consideration. You'll need to read a 50 page book on how to use lspcad and then you'll realize that it's nearly impossible to get any kind of descent reading of your drivers in a normal room. The resulting modeled crossovers are also significantly complex. Without proper environment and tools, it becomes extremely frustrating. Learn from my mistakes and save your money would be my recommendation.
If you need any help PM me, or if you would like to try play around with lspcad pro. I have it.
Biggest misconception is that people believe that they can tune their speakers to in-room response. This is completely false. The speakers have to be tuned in an anechoic chamber at 1m distance. Not in-room at listening distance, etc. It's a waste of time.
