i hope that's the right amount lol
That is not going to be too high. If it works for you, go for it.
Shannon can I ask if my speaker frequency response range is 50Hz-22kHz +/-1.5dB is this okay to listen to Ultrasonic on? Or does my lower end need to be 20hz?
Sorry in advance I know you probably get this question a million times.
Warm regards,

The standard for "CD quality audio" is 20 Hz to 20 kHz. 20 Hz is bass so low that it's relatively close to the lowest sounds human ears can register.
20 kHz is necessary for ultrasonics, because we use the audio range from 13 kHz to 20 kHz for ultrasonics. But for masked audio, the range is going to need only to cover normal speech, which is usually well covered by 1 to 4 kHz. So 50 Hz low end is fine.
