If multiples of identical speakers
are used in a combo or cabinet, the overall power rating is calculated by
multiplying the individual speaker rating by the number of speakers in the cab,
eg: 4 x 25 watts = 100 watts. However, when speakers are mixed, the lower
rating is used to make the calculation, as both speakers draw the same power
from the amp. For example, in the case of one 60 watt speaker and one 25 watt
speaker in the same cab, the effective power rating is calculated as follows:
1 x 25 watts + 1 x 25 watts = 50 watts total
It is not critical to match the power handling of a speaker
system precisely with the power output of the amplifier but, as a general rule,
the power rating of the speaker(s) should be at least equal to that of the
amplifier.

All guitar
speakers have just two connectors, one marked positive (+) and the other
negative (-). If one speaker is wired the wrong way around in a multiple
speaker configuration, it will not damage the amplifier. However, it will be
‘pushing’ when the other speakers are ‘pulling’, resulting
in the cancellation of some frequencies in the overall sound. It is therefore
important that the correct wire goes to the correct terminal.
Replacing
the loudspeakers in your cabinet or combo may affect the manufacturer’s
warranty.
