"PBECISION SOUND... BY DESIGiI"
FOSTEX specializes in the manufacture of a
comprehensive range of professional audio
equipment including loudspeaker systems and
components, microphones, amplifiers and stereo
headphones. Our goal at all times is to provide
products which will excellent performance and
reliability.
This demands a fully integrated manufacturing
system, from continuing reseach and development
of basic materials through extensive, strict, quality
assurance programs.
All majoi components and critical such as cone
materials and diaphragm assemblies are
manufactured using advanced technology, in our
own factories, These methods, together with
through enviromental testing and scientific
measurem€nts, assure the fulfillment of our qoal.

DIYIDING NETWORI{S
ln order to form as excellent speaker systerr. it is
absolutely necessary to use high performance dividing
network parts, such as, for example, a large-sized
inductor incorporating a cut core of low capacitor
that permits minimized loss or leakage, and an
attenuator R80 of high power input resistance, capable
of controlling inputs. The R8lois an attenuator kit of
high power input, which incorporates a special
transformer to permit attenuation per dB step down to

CONE TRANSDUCERS
FOSTEX Laboratory series loudspeakers are specially designed
for use in sound reinfqrsgrngnl, discotheques and studio monitor
applications.
All units feature
l)
I
Low mass, rigid, cones
2) High efficiency magnet circuits
3) Rugged durable construction
4) High power handling
The "L" and "F" series have edgewound aluminum or copper
voice coils on epoxy-mica bobbing for increased durability and
power handling.
The "FW" series features coated cones and extra-long voice
coils: two layers of round copper wire result in the optimum mass.
and density for the smooth reproduction of low frequencies.

These models are intended for demanding
high power applications.
Specially stiffened cones and heavy voice
coil assemblies increase power handling
at extreme low frequencies.
Dual spiders maintain long term stability
and linearity while preventing catastrophic
failure. These units are ideally suited for
super bass use :n sound reinforcement and
discotheques.

COMPRESSION I'RIVERS
FOSTEX compression drivers
are available in three voice coil
diameters, two throat sizes, and
offer aluminum, duralumin
or phenolic diaphragms and
alnico or ferrite magnet
structures.
The "1 inch" throat units feature
4 cm and 5 cm voice coils.
While the "2 inch" throat units
have a 10 cm coil diameter.
Diaphragms are field replaceable
with only a screw driver.

SUPER TWEETERS
FOSTEX super tweeters are available in two diaphragm sizes: 2 cm and 4 cm.
The T825/T925 feature extended smooth high frequency response and use the same 2 cm
aluminum diaphragm and voice coil assembly. The T825 uses a diffraction horn and offers
an unprecedented wide dispersion, even at very high frequencies. The Tg25 operates as a ring
radiator with controlled conrcal dispersion.
Similar in dispersjon characteristics, the T845,/T945 respectively, use the larger 4 cm aluminum
diaphragm for high power applications. fhe T725 is a horn loaded tweeter which offers extremely
wide bandwidth and is recommended for use in critical applications, such as studio monitors.
