Assitance required on decoding Speaker Response Graph

Sound is measured in terms of frequency (Hz). The loudness is measured in decibels (dB) based on pressure levels of the sound.
20Hz to 20,000Hz (20kHz), is the range of typical human hearing.
Reading the chart is actually pretty simple. The chart shows the range of frequencies (from low to high) horizontally and the Sound Pressure Levels (SPL) in Decibels (dB) vertically. The frequency range represented on this graph is 20Hz to 80,000Hz (80kHz), The upper end of the graph is 100 Khz
Ideally you would like to have the graph which is flat-- meaning that the speaker produces the same sound level across all frequencies. This speaker emphasizes the higher frequencies starting at 4 Khz to 35KHz. Note you need a 3dB increase in SPL to be able to hear the difference is sound- here we have 10 db difference
