That's what i presume happens.

I'd be interested to see your results. Just bought the last pair of those tweeters from partsexpress (sorry guys).

Zvu either you're not reading that graph correctly or I'm confused on what we're talking about. I thought Scott was talking about subharmonics being produced below the fundamental? A tone plot would be needed to show this, because an HD sweep does not show subharmonics, just ones above the fundamental. Your plot DOES NOT show a reduction in subharmonic distortion at 8.7khz, it shows a reduction in 3rd harmonic distortion at 8.7khz: precisely at 26khz. Which is a different topic.

Now why that happens seems odd, I know of no mechanism for it since the distortion is produced in the motor itself, after the filtered signal.

Or maybe Scott just blurred the lines between the two things and each of us took a different message from him.

I understood that we are talking about distortion rise that can be measured lower in the audio band when resonance at 27KHz (in case of Seas 26KHz) is excited.

If i misunderstood, i do apologize.

Might be a bit before I get to these, but I'm planning to use the W8-2096S underhung woofer from TB with them. I'll see what I get when I get there...

Later,
Wolf
