With many high-quality loudspeakers, you can make separate
connections to the high- and low-frequency drivers
(1)
. If your
loudspeaker allows it, you can improve the sound further by using
separate amplifiers for high and low frequencies. This may allow
you to increase the volume without distorting the sound. As each
amplifier is operating in a smaller bandwidth, intermodulation
distortion may also be reduced.

1. The ‘driver’ is the mechanism inside the case of the loudspeaker which actually
makes the sound. Most high-quality loudspeakers have drivers for high, low and
often middle frequencies and the capability to connect them separately.
However, the lack of this facility is not necessarily a sign of low quality
(as some of the finest loudspeakers in the world have proved)
Instead of one stereo power amplifier, you may prefer to use
two monobloc amplifiers (such as our 125M) in conjunction with
your PA10.

the loudspeaker it is feeding and use short loudspeaker leads. Use high-quality,
screened phono leads to connect the amplifiers
