To improve the sound further, you can use separate amplifiers for
high and low frequencies. This will 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.
Connect the output of one channel of a preamplifier (such as our
PA20R) to
INPUT
on one 125M. Connect

on another 125M. Connect one 125M to your
loudspeaker’s high-frequency driver and the other to the low-
frequency driver

.
For stereo, you will need to duplicate this arrangement for the
other channel.
Some high-quality loudspeakers have separate drivers for the
middle frequency range as well as high and low. In such cases
it may be possible (for details refer to your loudspeaker
instructions) to run separate cables for each frequency range
to tri-wire the loudspeakers.
If you wish to do this, you will need to connect two wires to one
terminal. We recommend that you use stackable BFA plugs for
this purpose. These are available from your retailer.
The arrangements described above and on previous pages are
only suggestions and do not cover all the connection possibilities
for amplifiers and loudspeakers.

retailer who will be happy to discuss your specific requirements.

1. This simple connection method works with any combination of TAG McLaren Audio
F3 Series amplifiers because they have matched gains. If you want to connect a
different manufacturer’s amplifier, you may need to use an active crossover or a
gain-setting facility. Please contact your retailer for advice if you wish to do this
