Adjusting the HF Level:
The PX1122M and PX1152M loudspeakers have a jumper that allows for attenuation of the HF level by 3 dB.
1. Remove the (6) screws that attach the grille to the enclosure (Figure 5).
2. Remove the (4) screws that attach the woofer to the enclosure, and disconnect the wires that attach the woofer to the
input panel (Figure 6).
3. The crossover is located on the inside of the enclosure, on the right rear wall. Move the jumper on the bottom of the
crossover to the desired location (Figure 7).
4. Reconnect the wires that attach the woofer to the input panel (reverse of Figure 6). The red wire corresponds to the
positive terminal, and the red and black wire corresponds to the negative terminal. Reattach the woofer to the enclosure
using the (4) screws.
5. Reattach the grille using the (6) screws (reverse of Figure 5).
