This can allow a reduction in the number of amplifiers and subwoofers to reach the desired bass level. As shown in Figure 9, connect MaxxBass between the crossover and the subwoofer amplifier on the subwoofer path. Using MaxxBass on the subwoofer path allows a reduction in the number of amplifiers and subwoofers, and power consumption to reach
