Home Speaker Asylum

General speaker questions for audio and home theater.

So... some folks display them

At the risk of stirring things up -- i.e., for better or for worse -- ASR is offering assessment of HD in loudspeakers.

HD levels tend to be high, especially at lower frequencies ("doubling" -- at very low frequencies, the output of the system at the fundamental frequency may be quite low, but there is lots of second harmonic output).

There is (I would say) controversy as to the audibility or "impact" of fairly high levels (> 1%) HD in loudspeakers -- depending upon the fundamental frequency, of course.

It's still something of a can of worms, as best I can tell.


all the best,
