Example, N501 8A. L.F. circuit.

Four resistive(power consuming components) in series configuration.

Amp to speaker wire(2x6 = 12 ft.), internal speaker cabinet and crossover wiring(2x3 = 6 ft.), 2 ohm DCR choke, driver Re = 6.3 ohm.


*18 AWG wire: 0.006385 ohm per ft. 18 ft. = 0.115 ohm

Current in circuit to give 3 Watt in Re is 0.69 amp. Amplifier power required to deliver 3 watt into Re is I(squared) x R( total in series),

0.69 x 0.69 x (0.115 + 2.0 + 6.3) = 4 watt


*8 AWG wire(0.0006 ohm per ft.): gives 0.69 x 0.69 x(0.108 + 2 + 6.3) = 3.96 watt from the amplifier.

A difference of 0.04 watt, giving a power change = 0.044dB at the amp, less at the driver.


Inaudible.


*If the wire had zero ohms resistance the amp power would only reduce to 3.95 watt for 3 watt at the driver.


*Using a 0.6 ohm choke and 18 AWG wiring requires 3.34 watt from the amplifier, a 0.66watt (0.78dB change).


I wouldn't get too fussed about the wiring.
