System Type 2
Network Jumper Setting
Type-2B: Tweeter and midrange positioning
are the same as in Type-2A, but the woofer
is located farther forward. This results in a
more extreme woofer listening angle of ap-
proximately 70°, with a delay of 28cm rela-
tive to the mid. Subsequently, level attenua-
tion is applied to both the tweeter and mid
while also adjusting filter characteristics
appropriatly for the mid/woofer transition. In
this case, changing the midrange high-pass
to a low Q 3rd order and the woofer low-
pass to very high Q 2nd order results in an
acoustic crossover point of 500Hz.
Notes:
• Highlighted tweeter level jumpers are the recommended settings for each configura-
tion, but 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 or tri-wire mode), the appro-
priate signal link jumpers must be removed.
