System Type 1
Network Jumper Setting
Type-1B: In some cases it may be possible
or desirable to mount both drivers close to-
gether with on-axis positioning, but not quite
at same distance to the listening position.
In general, it is assumed that the tweeter is
the closer of the two, as would be the case
if it is mounted over the woofer. While there
will obviously be some tolerance associated
with different vehicles and installation meth-
ods, this difference is considered to be
approx. 12cm. Phase linkage is accom-
plished by inverting the tweeter and using a
slightly lower Q 3
Type-1A, combined with a low Q quasi-2
Order low-pass on the woofer. This results
in an acoustic crossover point of 2.2kHz.
Notes:
• Highlighted tweeter level jumpers are the recommended settings for each configura-
tion, but some user adjustment may be desirable.
• Transfer function simulations only illustrate the effect of the filter upon the input sig-
nal, and therefore do not represent the actual frequency response of the system.
• If separate channels of amplification are used (bi-wire mode), the appropriate signal
link jumpers must be removed.
