Thanks, will give that link a try. Of course, loudness is not the ONLY criteria (criterion?) for assessing a speaker, but loudness with clarity and fullness of sound (which is subjective) and without distortion, seem like desirable traits. And yes I understand that Watts-RMS is not the only thing that affects a speaker's loudness. . .

Thanks,
Jim
