CHAPTER 2
Biamping connections
If your speakers can be biamped,
they will have separate input posts for
the woofer and the tweeter sections.
This diagram shows how to cre-
ate a very efÞ cient system with an
active external crossover. The cross-
over will split the incoming preamp
signal into two frequency ranges: one
above and one below the cross over
frequency.
True biamping is very efÞ cient
because each ampliÞ er channel only
receives and ampliÞ es the range
required for its driver. For example, in
the diagram below, the right channel
only am pli Þ es the low frequencies,
and the left channel only ampliÞ es the
high frequencies.
Make sure that you adjust the
crossover frequency to suit your

the speaker owner's manual for this
speciÞ cation.
An alternative connection method
is to have one ampliÞ er running the
two woofers and the other running the
two tweeters. This is useful if your am-
pliÞ ers have different power ratings.
Use the more powerful ampliÞ er to run
the woofers.
