  • Page 2: Frequency Response

    This measurement is useful in determining how accurately a given enclosure reproduces an input signal. The frequency response of the Impulse 1582 is measured at 1 meter using a 2.83 volt swept sine input. As shown in Figure 1, the selected drivers in the Impulse 1582 combine to give a smooth frequency response from 55 Hz to 19 kHz.
