I didn't think it was to bad. I have a dedicated treated 11.5 x 14 room.
I have a pair of subs, moved them around the room while using REW to measure each position. Once I got the placement close to my liking I then used the on board adjustments of the sub and my Anthem ARC to dial it in.
Getting them placed was a couple hours and tweaking them took longer but you'd expect that.
