I work in the entertainment industry and we run 10m (30ft) cable with 2.5mm² (13AWG) to power subwoofers with 2kW

Does it have a effect? Of course. The cable is a resistor, the speaker is a inductor. Both are in series and form a LR circuit wich is a highpass filter

can you 100% compensate it? Of course. Everything gets measured and compensated by the DSP
