Connection Examples
■ Full-range Connection
Each speaker features three input/parallel connectors – two 1/4" phone jacks and one
Neutrik NL4MP connector. Use either a phone jack or the Neutrik connector to receive
input from your sound system/power amplifier. One of the spare connectors can be used
to parallel-connect an additional speaker (keeping in mind the impedance
considerations mentioned below).
Impedance Considerations
We do not recommend connecting more than two 8-ohm speakers in parallel. Two
parallel-connected 8-ohm speakers have a total impedance of 4 ohms, which is the
minimum that should be connected to one amplifier output channel. The R112/R112C,
R115/R115C, R12M/R12MC, R15M/R15MC and R118W/R118WC are 8-ohm speakers,
and two of these can safely be paralleled on one output. The R215/R215C, however, has
an impedance of 4 ohms and should not be parallel-connected with another R215/
R215C or any other model.
