Does anyone know the actual frequency response for the Echo 2? or any typical audio speaker measurements for the Echo 2?
“The Frequency Response specification attempts to describe the range of frequencies or musical tones a speaker can reproduce, measured in Hertz. The range of human hearing is generally regarded as being from 20Hz, very low bass tones, through 20kHz (20,000Hz), the very highest treble.” via Polk
