An optional iQ 10P (passive version) can be ordered if (part no. 8001 2210)
A loudspeaker driven in Biamp mode offers a number of performance advantages, such as increased system headroom. Audio program materiel is made up of many different frequencies and harmonics. In music materiel, most of the energy is in the low frequencies, with less in the highs. When both high and low frequencies are present in a signal, the stronger low frequencies can use up amp power, leaving little or no reserve for the highs, so they are more likely to cause the power amplifier to clip. In a Biamp driven system, a smaller amp can handle high frequencies, LF amp clipping is less of a factor, and less overall amplifier capacity is needed due to the efficiency improvement in the absence of a passive crossover.
