I can't tell much of how your room looks from that video, but tow in is a different animal as far as tonal balance... a full tow pointing at the ears should be as close as you can get to the actual frequency response of your speaker. As you turn the speakers outward, you star rolling off the top end - mid, the farther you turn toward straight, the more you roll off the top, at some point, you will start dealing with the interaction of your speakers dispersion bouncing off the side wall and that will also effect your tonal balance along with the top end roll off. Then with panel speakers or baffleless designs, you have to deal with frequencies being projected from both sides of the speaker. With these 2 designs, you have much more room interaction to deal with.... My post were mainly directed to the Op who is using a standard baffle mount drivers with his B&W's
