21. When damping control is enabled a lowpass filter cutting around 400 Hz is automatically inserted into the amplifier chain This feature is intended to be used only for subwoofer applications Another advantage offered by the damping control feature is that in adding the series equivalent output resist ance to the amplifier chain the variation of the voice coil resistance due to heating can be taken into account This allows to obtain a correctly damped bass response at aver age working condition where the voice coils is subject to heating due to the passage of current For example if the subwoofers are going to work at close to full power an additional negative resistance of 1 to 2 Ohms should be added to compensate the high resistance generated by the heated voice coils to obtain a correctly damped response On the other hand if the same subwoof ers are working at low power a smaller negative resistance should be added in this case the cooler voice coil presents a smaller series resistance to be compensated Leaving too high an equivalent series resistance results in an overdamped system Section area Nominal Length Resistance mm AWG resistance ms ohm 5 0 12 2x1 5 16AWG R 12 O km 10 0 24 20 0 48 5 0 07 2X2 5 13AWG R 7 4 0 km 10 0 15 20 0 30 5 0 05 2x4 11 AWNG R 4 50 km 10 0 09 20 0 18 TABLE 10 Typical speaker cabling resistance On TABLE 11 notice the exceptionally high value 3 8 ohm when the driver
