Fostex GZ-1001 Brochure

The GZ Series of high performance speaker
systems has been developed in pursuit of

true fidelity reproduction throughout the

audible spectrum. These absolutely natural
and live sounding systems make you for-

get about the speaker source, so clearly is
the acoustic image positioned within the

rich sound field. A true dipole radiator de-

sing provides startling front-to-back depth

perception. The GZ Series directly repre­sents the achievement of true fidelity- not

only for traditional music, but also for new

sonic dimensions-with accurate reproduc-

tion of all information from any type of

program source.

IEDGELESS WOOFERS SLE34W

(GZ2001) AND SLE24W (GZ1001)

-ARTICULATE REPRODUCTION
OF THE FUNDAMENTALS.

The cone surround, weak point of

most cone woofers, is completely
eliminated in theSLE34WandSLE24W.
An acoustic low pass filter in the
form of a sloted ring replaces the
conventional cone surround. The
voice coil/cone assembly is sup­ported by push-pull, distortion-can­ceiling double spiders. Employing
also a super heat- resistant voice
coil, this special synthetic material
(SM) cone reproduces powerful and
articulate low frequency sound-the
fundamentals of music. Of particu­lar note are the excellent transient
response and low distortion -the
perfect complement to the Printed
Ribbon Planer Loudspeaker.

THE PRINTED RIBBON PLANER LOUDSPEAKER-PATENTED TECHNOLOGY.
The GZ Series employs the Fostex RP (Regular Phase) principle em­bodied in the acclaimed Printed Ribbon Microphone Series, a techno­logy protected by 19 patents pending. An extremely thin and lightweight
diaphragm is used whose entire effective plane is driven at the same
phase. The mass is small and uniformly driven, which results in high
efficiency and durability not found in similar units. This is a unique

loudspeaker with all the classic characteristics: flat frequency response,
high definition, superior transient response, low distortion and unusually
good front-to-back depth perception.

I MID-BASS FS41RP (GZ2OO1)-

ACCURATE REPRODUCTION

OF IMPORTANT BASS HAR­MONICS.

With the tremendous progress in
music program sources, the role of
the mid-bass is becoming increas­ingly important In the nearly perfect
GZ2001 4-way speaker system, the
mid-bass FS41RP handles the im­portant 200 Hz-1 kHz range, a key
to excellent sound reproduction. A
powerful magnetic circuit uses a

1.8 kg. high coercivityferrite magnet.
The planer diaphragm is made of

polyamide film, onto which the high
density voice coil is precision etch­ed. The result: brisk and lively mid
and mid-bass reproduction.

ISUPER TWEETER FT7RP-

HIGH FIDEUTY REPRODUCT1ON
CLEAR UP TO 45 kHz.

The super tweeter FT7RP boasts a
flat, non-distorted response clear up
to 45 kHz, far beyond the audible

range of human hearing. The 12.5

mm effective width diaphragm is

made from an extremely lightweight

polyamide film of 12.5.u thickness,
and it is formed in a special rib pat­tern. Dispersion is further enhanced

by making the front and rear dimen­sions of the magnet assembly non­symmetrical. This super tweeter
employs a Samarium Cobalt magnet
3 times more powerful than conven­tional units. Due to this design,
super high frequencies and impor­tant musical harmonics are faithfully

reproduced in a wide dispersion pat­tern.
