Series/Parallel - It is possible to utilize various series/parallel'hook-up' topologies to increase the number of

driven on an amplifier. See diag. 4 for one example of a series/parallel hook-up topology. .

Note: Mis-matching the speaker impedance such that it is below the minimum impedance rating of an amplifier channel can
damage the amplifier and degrade performance. If the application requires more than 2 speakers per amplifier channel
---+-
wired in parallel, a distributed line system should be considered. Also check your amplifier's manual for cautions and
recommendations.
Importance of Correct Polarity ("In-Phase/Out-of-Phase")- When two loudspeakers are wired with opposite polarity
("out-of-phase") relative to each other, the low frequencies of the loudspeakers cancel each other, even though the speak-
ers are "working hard." Trying to correct the lack of bass with an equalizer can damage your loudspeakers-- equalization
cannot correct polarity errors. Always make sure multiple speakers are connected in proper polarity. (See "Poor Low
Frequency Output" in the Troubleshooting section for instructions about how to detect and correct polarity problems.)
