How do I test the sub
The best of course is outside away from any boundaries. Barring that, put it in the middle of the room away from as many boundaries as possible and put the mic about a foot away from the main driver. It will give a decent near field approximation. You do have the floor as a boundary, but unless you're prepared to hang the sub from the ceiling, you have to live with that..

Also, what causes large drops like that? The room, the sub
The room. The sub will output exactly what its specs say, so it's really not required to test it.

I don't have that setting on the onkyo nr1000
Yeah, you do. If you can set a crossover, that means the mains are set to small. Their low frequency is high passed at the crossover frequency. The sub is low passed at the crossover frequency. The two combine for a flat response....
