Type-2A: For the tweeter in this case,
pathlength from the listening position is con-
sidered to be 85cm, at approximately 10-
15° off-axis. Due to the low door location
however, the listening angle for the woofer
is close to 50° off-axis, resulting in a relative
delay of 18cm. Therefore, minimal delay in
the woofer is achieved by employing a semi-
1
st
Order 3dB/oct. low-pass. This integrates
well with a steep 4
th
Order high-pass on the
tweeter, for a resultant acoustic crossover
point of 2.15kHz.

Network Jumper Setting
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.
