Type-2B: Tweeter distance and angle are
the same as above, but the woofer is located
farther forward. This results in a woofer lis-
tening angle of approximately 70° off-axis,
with a relative delay of 36cm. Again, mini-
mal delay in the woofer is achieved by em-
ploying a semi-1
st
Order 3dB/oct. low-pass,
which still integrates nicely with a 4
th
Order
high-pass on the tweeter as long as some
additional level attenuation is applied. The
resultant acoustic crossover point is
2.05kHz.

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.
