30db drop from 20hz to 20khz??

Hi guys. I am just getting started with REW and was trying to get some baseline measurements done. The good news is my baseline setup looks pretty similar in shape to the recommended house curves. The odd thing is that no matter what I do with the speaker position, I get about a 30db drop from 20hz to 20khz. I am not sure what to make of this and was wondering if anyone has come across this?

Is there another graph that you forgot to upload? The one in your post shows a drop of less than 20 dB.

Regards,
Wayne

Ooops...you are right. I guess I deleted it by mistake. I will need to redo the curves. However, even a 20db drop seems very odd to me. Have you ever experienced this before?

That looks like an entirely normal response for a listening position measurement.
