Verify that the polarity of the connections to all of your loudspeakers are correct. When more
than one loudspeaker reproduces the same frequencies, but with opposite polarity, there will be
sound cancellations. Therefore, if any of the loudspeakers are wired so that the +/- connection
polarity is reversed with respect to the others, incorrect reproduction will result. Most notably,
the bass response will suffer. This is especially true when loudspeakers are situated in adjacent
positions where the sound waves readily interact with each other.
Two cabinets can be connected in parallel, at which time the signal can be linked through from
one loudspeaker to the next. Make sure that the linked cabinets total impedance is more than the
minimum impedance indicated on the amplifier.
Systems total impedance can be calculated with the following formula:
6.1 Amplification
There is no exact answer to the question of what amplifier size you should use for a loudspeaker.
The loudspeaker power rating in Ohm’s specifications only means it has passed a standard power
test. This provides a rating that can be used as a point of comparison with other loudspeakers.
This rating does not necessarily correspond to the best amplifier size to use nor is it a measure
of a “safe” amplifier size to use. Rather, the amplifier should be sized according to both the sound
levels required and the type of audio signals that will be reproduced. If you are unsure of how to
determine this, consult with a qualified professional or contact Ohm Technical Support.
Preventing damage to the loudspeaker is a function of operating your audio system so that the
loudspeaker is not stressed beyond its design limits.

Normally systems minimum impedance should not be lower than 2 ohms, with Ohm D class
amplifiers not lower than 4 ohms.
