We wish to thank you for purchasing the Fostex
speaker unit. Please read the following before
using to ensure proper operation of the unit.
Midrange sound is most important in reproducing music. FS21RP and FS41RP are midrange
speaker units of the Printed Ribbon full plane
driving which Fostex have succeeded in making
a practical unit for the tirst time in the world.
An absolutely clear and delicate sound
FOstO(
is
attained by using an extremely thin and lightweight diaphragm, and driving the eltective area
of this diaphragm at the same phase throughout. lt is of extraordinary high efficiency and
endures high input power, unlike the condenser
type or similar type speaker units. As crossover with woofers and tweeters is smooth, it is
possible to assemble a high class speaker system which can totally reproduce musical information of the program source.

instruments.
2. As the construction is such that sound is also
emitted from the rear, the sound will not be
affected by the enclosure thus ensuring a
very natural sound,
3. Reproduction of wide dynamic range sound is
possible because of its high efficiency and
capability to withstand high inputs.
4. Frequency response is flät and the high region
limit is largely extended.
5. Transient response is excellent and distortion
is low.
6. Designing a network is simple as the impedance characteristic is flat over a wide
frequency range.
