Type-2A: For the tweeter in this case,

pathlength from the listening position is con-

sidered to be 85cm, at approximately 15-

20° off-axis. Located at a moderate vertical

distance down from the tweeter and basi-

cally flush to the panel, the midrange is

8.5cm farther away and presents a listening

angle of about 40-50°. Due to the low door

woofer location however, the listening angle

for the woofer is close to 60° off-axis, with

its acoustic center 8cm farther relative to the

mid. For the tweeter/mid transition, a 3rd

order high-pass and semi-1st order low-pass

with increased level on the mid are engaged,

resulting in a summation point of 4kHz. Op-

timum integration between the woofer and

mid is then achieved with 4th order high-pass

and low-pass at 700Hz.

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.
