Speaker Frequency Conflict?

[Xebec]

I've read in multiple threads that our speakers need to support 20kh. But, on one of the instruction pages, Shannen wrote this:

"Ultrasonic format subliminals require speakers that can reproduce at least 29 kHz frequencies, and higher is better."

So, which is it?

20 kHz is minimum for ultrasonics.

Thanks.

If it said 29, that was a typo. It's 20 kHz minimum.
