I wasn't really sure where to post this, and I did search. I'm looking for a full range test tone from highs all the way through to the bass notes. I'd like to see if my system has any quiet (non existant?) points.

White noise.

White noise.

I was thinking a progressive movement.

Oh. Like a sweep of pink noise starting at 20 hz and moving slowly up to 20khz.

I think i have an autosound 2000 disc that has that on it.

Dont' forget though, your ears wont' hear all tones at the same true volume to be at the same volume. Essentially some frequencies are "louder than others. Meaning if all tones create the same SPL, you'll hear some louder than others. It's a bell curve shape. Meaning it'll start low and quiet, get louder and higher up to a point, then get really high, but quieter again. I guess if you hear any sharp drops it could be a gap in F/R, especially near crossover points.

Urei Sonipulse.... Produces a series of pulses set to different frequencies so that standing waves are not gauged. The reason for doing this is in most music a sine wave is not going to be used, also sound is usually very random. And pink and white also have a tendency of producing very unnatural standing waves in loudspeakers systems. So if you can find a UREI Sonipulse 100-A you will be set....

Problem is you can't find one. So use a sine sweep or White/Pink noise... Most of all just use your ear. If it sounds good to you then nothing needs to be done.

i've heard that frequencies like 2400 hz or something like that are the most painful/damaging, is this true?

I think it depends on the person/s who is/are listening....

Did you ever get the issue with yours figured out??

yeah, somewhere around there is the resonance frequency of the ear canal. It's in between 2-3 k for just about everyone.
