• ES cone and center cap are adapted.
This new diaphragm material has the
fine, supple and high density fiber, and
its characteristics successfully improve
the mid-high frequency reproduction.
• ø110mm strong ferrite magnet is em-
ployed.
• Well tuned Qts / Mms values for ease of
use in the back loaded horn enclosure.

Recommended Back Loaded Horn Type Enclosure
• This example s h ows a ‘back
loaded horn’ type enclosure for
FE166En.
• FE166En’s magnetic c i r c u i t
with ø110mm large ferrite mag-
net provides sharper resonance
and makes the unit suitable for a
back loaded horn.
• 15mm thick plywood panels are
used for the main section and
21m m thick plywo o d for the
side panels to ensure a strong
enclosure.
• Two way system using super
twee t e r T90A is also reco m -
mended.

• This example has sufficient internal volume. However, if you prefer ‘tighter’
sound reproduction, you can reduce airspace using sands or other ll material.
• Placing thin sound absorbent material as shown enables reduction of peaks & dips
around 150 to 400Hz band width. However, it may reduce transient response. You
should adjust it to your taste.
• In order to avoid unwanted mid/high frequency dispersion of the horn, we recom-
• FE166En is designed for a back loaded horn
mend damping the enclosure with ller and sound absorption material.
Bass Reex Type Enclosure
type enclosure. It is generally unsuitable for
bass reex type enclosure use because of its
over damping sound characteristics. Howev-
er it is possible to use the FE166En in a bass
reex type enclosure as shown.
• This example is a narrow and tall style bass
reex type enclosure. Internal volume is 15
liters tuned to approximately 65Hz (Fb).
• Low frequency response from around 150Hz
is gently damped with a controlled peak at
60 to 80 Hz.
