Rotating a QX (or other symmetrical speaker) in EASE

The box is on the axis of symmetry. This is 100% normal for any symmetrical loudspeaker in Ease and is not exclusive to the QX product.

When symmetry is on, you cannot rotate a loudspeaker at all if it is on the axis of symmetry (because it is technically no longer symmetrical).

You must move it slightly in the +/-X plane to do any calculations. But, you will then have a duplicate mirror image speaker on the other side of the x axis. You can either ignore the mirror image or you can turn off symmetry in your project and use the loudspeaker on center of the X axis.
