Well, you do have an air gap between curtain and window. That should help a bit down low.a 1.5 cm thick curtain will not do anything to frequencies below 100Hz so I didn’t bother turning the subwoofer on.
Any idea why now the standing wave is more pronounced than before? Is it the fact that one way you damped a mode, which leads to increase of another?
