in front of you ?
TBH when i had the 121 rig i never stood to the side of it. Always directly in front maybe up to 2-3 ft max from it.
I liked the 210 combo they had where the speakers were side by side rather than one above the other. The cab could tilt back to approx 35-45 degrees if i remember right tilting upwards to let you hear it better.
