3. Disconnect one end of the lead connected between the
two 10 inch loudspeakers.

failure. The speakers should all sound generally alike
with a slight difference between the 8 inch and 10 inch
loudspeakers.

of each loudspeaker individually. Each 10 inch speaker
should measure between 12 and 16 ohms. Each 8 inch
speaker should measure between 5 and 8 ohms. Read-
ings outside of these limits indicate possible failure.
