RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT REMOVE COVER (OR BACK).
WARNING:
NO USER - SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
Avertissement:
To reduce the risk of fire or electric shock, do not expose apparatus
to rain or moisture.
pour réduire le risque d’incendie ou de choc électrique, ne pas exposer
cet appareil sous la pluie et l’humidité.
The lightning flash with arrowhead symbol, within an equilat-
eral triangle, is intended to alert the user to the presence of
uninsulated "dangerous voltage" within the product's enclo-
sure that may be of sufficient magnitude to constitute a risk
of electric shock to persons.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in the
literature accompanying the appliance.
Read these instructions.
Keep these instructions.
Heed all warnings.
Follow all Instructions.
Do not use this apparatus near water.
Clean only with dry cloth.
Do not block any ventilation openings. Install in accordance with
the manufacturer’s instructions.
Do not install near any heat sources such as radiators, heat
registers, stoves, or other apparatus (including amplifiers) that
produce heat.
Do not defeat the safety purpose of the polarized or grounding -
type plug. A polarized plug has two blades with one wider than the
other. A grounding type plug has two blades and a third grounding
prong. The wide blade or the third prong are provided for your
safety. If the provided plug does not fit into your outlet, consult an
electrician for replacement of the obsolete outlet.
Protect the power cord from being walked on or pinched particularly
at plugs, convenience receptacles, and the point where they exit
from the apparatus.
Only use attachments/accessories specified by the manufacturer.

Unplug this apparatus during lightning storms or when unused for
long periods of time.
Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way, such
as power-supply cord or plug is damaged, liquid has been spilled or
objects have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate normally, or has
been dropped.
The apparatus shall be used in an open area.
Cet appareil doit être utilisé dans un endroit a aire ouverte.
Apparatus shall not be exposed to dripping or splashing and that no
objects filled with liquids, such as vases, shall be placed on appara-
tus.
L’appareil ne doit pas êclaboussures et aucun objet ne contenant
de liquide, tel qu’un vase, ne doit être placé sur lobjet.
Mains plug is used as disconnect device. It shall remain readily
operable and should not be obstructed during intended use. To
completely disconnect the apparatus from supply mains, the mains
plug of the apparatus shall be disconnected from the mains socket
outlet completely.

Use only with the cart, stand, tripod, bracket, or
table specified by the manufacturer, or sold with
the apparatus. When a cart is used, use caution
when moving the cart/apparatus combination to
avoid injury from tip-over.

Impedance characteristic
Main Features
FE163En-S is a direct line from FE163 and is an over-damping speaker unit that has been developed based on all the skills that
Fostex cultivated in the past. Retaining the FE series' middle-high range bright and forceful sound characteristics, a fulfilled
low-mid range and a smooth frequency response up to a higher range are realized. A light-weight and easy-to-drive diaphragm
is driven by a powerful magnetic circuit. This allows to realize a linear response from low to high input level, a superb acoustic
field position and fine as well as powerful high-definition sound reproduction.
• Corrugation type light-weight fiber edge
While steadily holding the ES cone paper, a corrugation type fiber edge is employed to realize a higher compliance and to improve the
linearity. On FE163En-S, by changing the shape of edge inner/outer circumstances and peaks/troughs intermediate part, an edge-
specific resonance has been diverged and lightened for a better response from a low to high input level. Also a thick low-mid sound
even with an over-dampling characteristic as well as a clear and flat mid-high frequency response have been achieved.
• Three-point adhesion / pocket-neck damper
A three-point adhesion which binds the cone paper, spider and voice coil bobbin at the same line is employed to enhance the strength
of the inside rim of the cone paper for stable high frequency characteristics. Employing a pocket-neck damper which puts a pocket
shape at the damper neck section allows a three-point adhesion even with the use of a junction cable to the voice coil and reduces a
transmission loss from the voice coil to the input terminal.
• Low-distortion large ferrite magnetic circuit
A 145 mm diameter large ferrite magnet is employed for the magnetic circuit to ensure a substantial magnetic flux density. A nickel
plating process is applied onto the magnetic circuit metal part surface finishing. With a placement of copper ring to the inner circum-
stance of the magnet, a current distortion is lessened to realize a low distortion of the drive system.
• Highly-rigid aluminum die-cast frame
A high-rigid aluminum die-cast frame which securely holds a low-distortion large magnetic circuit and does not transmit an unneces-
sary vibration to the cone paper is employed.
• Gold-coated 205 Faston receptacle terminal / High definition OFC (Oxygen Free Copper) interconnection material
Less junction-loss gold-coated Faston receptacle terminals are employed to avoid a sound degradation as much as possible. Employing
high definition OFC cables lessen a transmission loss from the speaker input terminals to the speaker unit.
