Frequency Response Data
The frequency response graph, labeled 'SPL vs Freq', displays Sound Pressure Level (SPL) in decibels (dB) on the vertical axis (ranging from 50 dB to 110 dB) against frequency in Hertz (Hz) on the horizontal axis (ranging from 20 Hz to 40 kHz). The plotted curve shows the speaker's output across the frequency spectrum, with a general upward trend towards higher frequencies, peaking around 2 kHz and extending to approximately 25 kHz. The overall sensitivity indicated in the specifications is 90 dB.
*Peak power handling test. Pink noise butterworth filtered at 12 dB per octave with cutoff frequency of 100 Hz.
Please note that the frequency response measurements are supplied for comparison only and are not a measure of the low frequency performance which may be achieved in a fully optimised system.
