Where are you going to rent a measurement mic? And why? Are you going to rent a pistonphone calibrator with it? Just get yourself a panasonic capsule like everyone else - it's plenty good for diy, costs a few dollars and some time, and you can always have a mic to measure your speakers.
Long and Mcquade. 5$ day rental for a Reference Microphone and stand is a good deal in my book as i am not going to buy a $1500 peice for use 2 or three times. I thank you for the speaker workshop suggestion ill try that tommorow but i found another "realRTA" online and it worked. Told me what i could already hear. Cutting in the mid was nessicary, 600 to around 1400 was thick. ANd little bass responce below 90 Hz also expected. Other then that i think my other problems are related to a badly built x-over.
To get an accurate snapshot of the speakers themselves and not the speakers-room combination you need Speaker Workshop. In other words you need anechoic measurement, a measurement with the reflections removed from the acquired signal. RTA measurements include the wall reflections and do not give the speaker response (as you mentioned you wanted)
