SPEAKER IMPEDANCE MATCHING & HOOK-UP GUIDE: (Continued)
PARALLEL:
When wiring in parallel, the resistance of the speakers decreases. Two 8 ohm speakers wired in ( hooked-up ) Parallel
results in a 4 ohm load. It’s easy to calculate the effect of a resistive load when all the speakers are all the same resistance. It is really
not suggested to wire different resistive load values in Parallel ( 8 and 4, 16 and 8 etc. ) The formula for figuring the total impedance in
Parallel is the multiplication of the two loads divided by the sum of the two loads - i.e. putting two 8 ohm speakers in Parallel results in a
4 ohm load. Connect the Positive side of Speaker A to the Positive side of Speaker B - Connect the Negative side of Speaker A to the
Negative side of Speaker B.
COMBINATION OF SERIES & PARALLEL:
This is really just two sets of Series wired speakers connected in Parallel. This is how
you maintain a consistent load with multiple speakers. The importance of this is more evident when you have more than one cabinet to
connect to your amplifier. This is when you need to figure out the loads and how to wire them up without applying too low of a resistance
on the amplifier.
Simply connect the Positive side of Speaker A to the Positive
side of Speaker C.
Connect the Negative side of Speaker A to the Positive side of
Speaker B. Next, connect the Negative side of Speaker C to
the Positive side of Speaker D.
And lastly, connect the Negative side of Speaker B to the Nega-
tive side of Speaker D.
4 Eight ( 8 ) Ohm speakers wired in Series Parallel = a Total
Load of 8 Ohms.
