The typical
placement of speakers in the typical room results in a confusion of sound. You
end up hearing a lot of the room colorations and reflections mixed in with the
direct source. Sure, you can spend even more money and equalize the room. Even
then you may have to invest in an outboard crossover in order to compensate for
the loudspeakers design.
Avoid all these
problems with Fostex Near-Field Monitors. They are Point Source, coaxial
speakers. A,, the sound emanates from a point reference, just like in nature,
so all the sound reaches your ears at the same time. Stereo imaging is rock
solid.
This design produces
a "sweet spot" so you know that what you're hearing from the RM
Series will sound proportionally the same in a car, on a hi-fi system or
through a custom-tuned playback system in the studio.
An unusually low
crossover point gives you another imoprtant benefit not found in conventional
designs: vital midband information like vocals will not be modulated by high
impact low frequency sounds like kick drums.
The same RP patented
driver gives you uniformly flat high frequency response in all three models;
the woofers increase from 6,5 inches to 8 inches to 10 inches. The two drivers
in the RM 765 are the identical elements in the RM 865 3-way system, which simply
adds a 10-inch woofwr.
This larger system
is also ready for biamplification. In our listening tests with 800W -1000W per
side, these beauties have generated 116 dB SPL at the console with no audible
distortion. The Near-Field Monitors from Fostex give you clarity and punch and
definition - as loud as you need it.
The Initail
Reference
RP stands for
Regulated Phase. It's new a new trasducer technology which has been under
development at Fostex for the last ten years. So far, more than 20
international patents have been awarded. The first products with the RP
Technology were Headphones. The idea worked so well, the inventors immediately
began applying it to the reciprocal trasducer, the microphone.
A whole series of
microphones now exists' with the same basic principles embodied in the new RM
765 and RM 780 tweeters. The essential idea of this RP Trasducer is a flat,
thin film diaphragm onto which the voice coil is printed; this assembly is then
suspended between magnetic circuits arranged on both side of the diaphragm,
with the same polarities facing each other and the opposite polarities adjacent
to one another.
The end result of
this arrangement permits the diaphragm to be driven with absolute uniformity.
Which means it doesn't sound differently at different levels. It provides the
same uniform frequency response across an extremely wide dynamic range.
It won't break up,
either. Which means three won't be the usual high frequency distortion to mask
the over-use of 12 kHz boost, for example.
Because the printed
film diaphragm moves identically in both directions, and the entire diaphragm
surface is with in the magnetic field, it by-passes all of the response
variations caused by conventional mounting designs. There simply is no
mechanically induced distortion in the RP tweeter. It functions as an edgeless
device.
In this sense, the
double spider design of the RM-Series woofers is the perfect complement to the
RP tweeter. In a conventional single spider design, the compliance from one
direction differs from the other. This difference produces unacceptable
distortion, particularly in the second harmonic region. Fostex engineers added
a second spider in a push/pull complementary configuration to cancel the
compliance effects of a single spider design. The result is a 10 dB improvement
in second harmonic distortion. A 2" voice coil/magnet assembly and a
computer modeled bass reflex design complete the profile of what is definitive
low and response in the Reference Monitor Series.
