Could you explain how you can tell that I don't have the crossovers engaged on the mains? Just trying to learn how to decipher the measurements.

I simply looked at the response and could tell it doesn't comply with a standard 80Hz crossover.
Below are two REW target diagrams showing what a subwoofer and mains should look like (in a perfect world) when a crossover of 80Hz is set in a receiver. The two outputs will combine for a perfect flat response.
MAINS should look like this (yours does not).

SUBWOOFER should look like this.

This is a poor way of doing this.
Hook up the output of the soundcard to the AUX or CD input of your receiver with a splitter Y cable.
Put the receiver in stereo mode. Now only the sub and mains will play. Be sure the mains are set to small and the crossover you like is setup (i.e. 80Hz).
Disconnect the Mains speakers (with the power off of course).
Now the sub only signal will output when REW is running and the crossover will be engaged. The sub will look like the diagram above for the sub....
Now shutoff the subwoofer and connect up the mains and run REW and the crossover will be engaged for the mains. The mains will look like the diagram above for the mains.
When you turn the sub back on you can take a measure of the mains + sub to see the crossover integration.
Use the Check/Set levels with Subwoofer test signal setup in the Settings screen to do all the tests..
