Generally, if you use the program for less than eight hours a day, you don't want to go below six. Eight is optimal, and most people can handle up to 12 hours a day without having too much trouble processing what they have exposed themselves to. I recommend 8 hours a day if you can do it, and more if you can handle it. Up to your limits of processing capacity, more exposure is better. Most people will peak at 8 to 12 hours of exposure, and after that will see slower results because they don't have enough down time for processing the input.
Speaker manufacturers tend to claim a higher frequency response than is actually useful on the speakers; they list the absolute limit of what it will reproduce without distortion at normal volume, not what it will reproduce clearly. You see the difference in listening to an ultrasonic on a pair of speakers with a frequency response rating of 20 kHz versus 22-25 kHz, it's obvious. My ultrasonics go up to 20 kHz, but that's not even the center frequency, which is lower.
Lower frequency responses will clip the audio, resulting in more distortion and thus less clear subliminals, leading to degradation of results and other potential problems. If your speakers are not capable of reproducing at least 20 kHz, you should either get a pair that can, or use the masked format. 20 kHz is the minimum necessary for clear reproduction of the ultrasonic subliminals we offer here.
