One speaker for all? No.
There is, logically, a correlation between drive unit size and sound stage, and we can say that as a general rule, as the surface area of the bass/midgange drivers increase, so does the sound stage, realism, power handling, effortlessness and maximum pressure output improves. Were this not so, we would make just the P3ESR and that would satisfy all users in all rooms at all distances and loudnesses.
