BC-series User Manual
Connection
BC-series speakers are connected via 2 spring terminals at the rear of the
enclosure. With the amplifier switched off, strip the speaker wire ends and
connect the
“+” wire to the red terminal and connect the “ - ” wire to the
black terminal.
When connecting to the amplifier
, refer to the amplifier manufacturer’s
manual to ensure that total speaker impedance ( Ω) on any channel is not
less than that recommended for the amplifier. It is also imperative that the amplifier does not deliver more
power than can be handled by the BC speaker. Refer to the amplifier manual and specifications below to
calculate this. Normally, it is recommended that the amplifier is capable of the RMS power rating of the
speaker but cannot ever exceed the Max power rating.
