poor sound palance and image focusing
When br-wmng Ihe speakers, loosen the terminal caps and remove the links. Use a separate twin cable from the amplifier
terminals to each pair di speaker terminals {figure 5] Correct polarity connection ?s even more cinicai m this case lo maintain

When cheesing cable, keep the total electrical impedance (out end back!
