It works out as half through the maths although the correct way to calculate is to multiply the swing by 0.707 (the reciprocal of the square root of 2).

If the supplies are +/-20v, your peak output swing will be 16.4v whereas the RMS will be 16.4 * 0.707 = 12.6v. This will result in an RMS current of 1.45A into 8R, giving 16.82W RMS output power.

Nice one,
David.
