• 15mm thick plywood panels are used for the main section
and 21mm thick plywood for the side panels to ensure a
strong enclosure.
• Two way system using super tweeter

Sound
Absorbents
• This example has sufficient internal volume. However, if you prefer 'tighter' sound reproduction
you may wish to use sand bags or fill to reduce airspace further.
Sands
•Placing thin sound-absorbent material as shown reduces peaks & dips from around 150 to
400Hz. However, damping may reduce transient response somewhat. You should adjust to taste.
Sound
Absorbents
Sands
• In order to avoid unwanted mid/high frequency dispersion from the horn, we recommend
damping the enclosure with fill and sound absorption material.
• FE166E is designed for a back loaded horn type
enclosure. It is generally unsuitable for bass reflex type
enclosure use because of its over damping sound characteristics.
However it is possible to use the FE166E in a bass
bass reflex type enclosure as shown.
• This example is a narrow and tall style bass reflex
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 - 80Hz.
