Connecting the Speakers

Each speaker features two input / parallel connectors — two 1/4" phone jacks. Use one phone jack to receive

input from your sound system / power ampliﬁer. The other phone jack can be used to parallel-connect an addi-

tional speaker (keeping in mind the impedance considerations mentioned below).

Phone plugs for connection to the phone jack inputs should be wired as

shown to the right. Be sure to use proper speaker cable — NOT shielded

instrument or line cable — for all speaker connections.

Impedance Considerations

When connecting speakers in parallel be sure to check

the rated load impedance of the power ampliﬁer. Most

power ampliﬁers are capable of safely driving speakers

with minimum impedance of 8 ohms or 4 ohms. A pair

of parallel-connected 8-ohm speakers have a total

impedance of 4 ohms. Two 8-ohm speakers can safely

be paralleled on one output. 4-ohm speakers, however,

should not be parallel-connected with other speakers.

These models can be connected in parallel, however, if

you are using a power ampliﬁer that can safely drive

load impedances of 2 ohms or lower. Check your

speaker impedance on page 18.
