Most likely yes. If you read this white paper from Harmon on the number and placement of subs for optimal listening, you would conclude that at least two subs properly positioned will give you a smoother response in your room than one. If you are the only one in the room, then you can position the one sub for optimal listening. On the other hand, if you move from that spot, or there are other positions in the room that you want to optimize, then more than one sub is required. The quality of the sub(s) will matter, but the positioning of them is most important, but difficult if more than one is involved. It may require a computer program to perfect, whereas one involves a more simple approach, trial and error. This is the white paper:
