Help please

This is a near field measurement with umik-1 of my crystal audio thx 10in sub. There is no active crossover. How is possible? What have I done wrong? When I measure sub+speakers with a full freq sweep, I do not get that peak between 100-350Hz.

My set up is 2.1, the sub is connected to the preout of a stereo preamp. The near field measurement was done with main speakers on mute (power amp switched off).

Also please note that the sub is excellently blended in the system, I do not hear it at all when playing music.

Please also note that rew warned after measurement for 48% distortion.

Select an actual output device rather than leaving the selection as default. Make some measurements at a much, much lower level that you can comfortably listen to and check what is actually playing the sweep.

Thanks you for the reply and sorry for my delay. It works fine now.
