Frequency
Frequency response does not reflect maximum output but shows its true response in a anechoic chamber. Typically you will see an elevated response in the bass response below 40Hz in room due to room gain, which can add around 6dB pr. octave under 40Hz depending on the size of your room.
Impedance
The impedance charts are electrical measurements of the loudspeaker’s resistance vs frequency.
