The ear is at its most sensitive in the midrange, so we recommend that, when

single wiring, you connect the cable from the amplifier to the terminals that directly feed the midrange driver.

Bi-amplification goes a stage further and involves the use of two separate power

amplifier channels for each speaker. It is not the same as having a fully active

system, because the speaker's internal passive crossover is still used.

If using bi-amplification, ensure that each amplifier channel has the same gain,

otherwise you will change the balance of the speaker. Check the absolute polarity.

Some amplifiers invert the signal, and a mixture of different types may cause a

dip in the overall response. If you have a mixture of inverting and non-inverting amplifiers, reverse the polarity of the connections from any inverting amplifier to the speaker.

Bear in mind that, even though midrange and, even more so, tweeter drivers can

(and only need to) handle less continuous power than bass drivers, the amplifier feeding them needs to have an adequate voltage swing in order to

supply the short-term high-frequency peaks in music without distortion. A high

voltage capability implies high power, so it is not particularly desirable to have a lower powered amplifier feeding the midrange and tweeter than is used for

bass drivers.





When single wiring, connect the cable from the amplifier to the lower terminals

on 2-way systems and the upper terminals on 3-way systems.
