Динамик широкополосный FOSTEX FE206En. Инструкция на английском языке

FULL RANGE SPEAKER UNIT
FE206En
Features
•  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.
•  o146mm 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 shows a ‘back
loaded horn’ type enclosure for
FE206En.
• FE206En’s magnetic circuit with
o146mm large ferrite magnet
provides sharper resonance and
makes the unit suitable for a back
loaded horn type enclosure.

• 21mm thick plywood is used for
main section and side panels to
ensure a strong enclosure.
• Two way system using super
tweeter T90A is also recom-
mended.
