After multiple tests we have concluded that the SOUNDBOKS 1 has a frequency range from 66hz to 20khz, but due to psychoacoustics - a sonic filter that makes your brain perceive sound outdoors as if it was indoors - you will perceive the sound all the way down to 46hz. This means that you will be able to enjoy the full range of sound all the way from a warm sub punch to the crispy top frequencies. Also, it is important to note that outdoor sound is extremely different from indoor sound. If you take an indoor speaker outdoors, it will lack bass and sound very tinny. When producing indoor speakers, only 15% of the sound comes directly from the speaker itself and 85% comes from the resonance in the room, whereas outdoor speakers are produced the other way round (85%/15%).
