A:Answer We provide two frequency measurements. Frequency response and frequency range. Frequency response is a classic anechoic measurement that has a +3/-3db variation and a frequency extreme of 50Hz at the low end and 28kHz at the top end. However, that's an anechoic measurement which does not reflect how speakers perform in real acoustic spaces. This is why we have a frequency range spec. Frequency range reflects what you are most likely going to experience in an actual acoustic space. The low frequency response in that spec is 45Hz, and be able to hear that reflected in instruments like a double bass.
