We only recommend bi-amplification when every component
in the system is the best available and there is no other path to
improving the system. In all other cases, you are better off in-
vesting in the best single amplifier. Caution should be used as
some amplifiers will oscillate using this configuration with pos-
sible speaker damage.
Vertical bi-amplification uses a stereo amplifier to drive each
speaker. Four identical runs of equal length of speaker cables are
required. (Two per speaker.)
Please review the information on page 4 regarding cable se-
lection and connection techniques before you connect your
speakers.
1. Connect two cables to each speaker as described in steps 1-3
on the previous page.
2. Designate one stereo amplifier as the left channel amplifier
and the other identical stereo amplifier as the right channel
amplifier.
3. Connect the preamp’s left channel output to both in-puts of
the left amplifier using two sets of pre-amplifier outputs and
two cables or one cable and a high quality single female to
dual male “Y” connector. Use the same method to connect
the pre-amplifier’s right channel output to both inputs of the
right amplifier. The M5-HP must be connected to one chan-
nel of each amplifier.
4. Connect the bass cable from the left speaker to the channel of
the left amplifier where the M5-HP crossover is connected.
Connect the tweeter/midrange cable from the left speaker to
the other channel of the same amplifier. Verify proper po-
larity.
5. Connect the bass cable from the right speaker to the channel
of the right amplifier where the M5-HP crossover is con-
nected. Connect the tweeter/midrange cable from the right
speaker to the other channel of the same amplifier. Verify
proper polarity.

a. Verify with the amplifier manufacturer that your amplifiers
are the same generation and sound the same.
b. If your amplifier has multiple impedance taps, try the 4 ohm
taps and 8 ohm taps to see which sound better. (They will
sound different) The Model Seven is an easy load and always
stays between 4 and 8 ohms so there is no danger of damag-
ing your amplifier or the speakers by using either set of taps.
Both cables must be connected to the same rated taps on the
amplifier.
c. All four speaker cables should be the same type and length.
While certain different cable types may work well together,
using identical cables on
the top and bottom insures perfect
blending.
The input screws should be snug,
but should not be over tightened.
Bare wires should never come into
contact with the aluminum dress
plate while the amplifier is on. Am-
plifier damage could result.
This connection method can only be
used in a system configured with
two identical stereo amplifiers
