First, make sure you're testing AT THE SOURCE to make sure it's as accurate as possible. Like an inch or so from the front of the speaker. It should never be higher than -32db there, it's loud enough, trust me. It's been tested in concerts and still works, so don't worry.
Aside from that, lower frequencies aren't the issue with masked, they're made to be within the range of normal human speech, which pretty much all speakers can produce. However, the ultrasonics should indeed be silent. So, any sound especially like a staticky sound or anything else, either means it's too loud, and judging by your Frequensee that doesn't seem to be the case (unless you're testing further away and NOT at the source like you're supposed to of course). OR, it's a case of the speakers being unable to properly produce the ultrasonic, and it results in distortion which won't get you the result you want. That seems to be the issue here. Many manufacturers list stuff as 20-khz or beyond, but to save money, don't actually MEET those specs in reality when tested. And since marketing is the issue there, and most people don't listen to stuff too far above the normal range of human speech, they chance it and misrepresent to appear to be higher quality than they truly are. That seems to be the case here. You'll need to change speakers, or use masked with these ones. I used masked for a lot of my AM6 run before switching to ultrasonic, and they both worked great. They both have the SAME messages in them, it's just a difference in delivery methods.
All of this is in the forum in stickies and threads and the manual etc. Explore around, there's a wealth of info to get you the most out of your listening.
