Why and where
Roundffusor1? Using
our R1 you can obtain aurally pristine
natural acoustical environments
for Recording Studios ,
High-End rooms, City &
Conference Halls, Cinema & Music
Halls, Swimming pools, Listening
rooms, Home theaters, CD
Mastering Rooms, Film mix and
dubbing stages, Music Schools
and practice rooms, Churches.
The R1 is used in the Ray Kimber's
IsoMike special
recordings.
We do the acoustical studies
and acoustical measurements for
all situations
The R1 brings in musical harmony
your recordings/movies with your
room and your brain.
The R1s
grouped surface reduce
drastically the reverberation
time (RT60) / echo in any kind of
rooms. There is the
R1's RT60
constant, which is 0.35-0.4 sec
regardless the room volume,
resulted from a 30% or less
room's surface covering (the 30%
is the
Heinrich Kuttruff's theoretical
limit of diffusion surface).
The total room area is including
floor and ceiling, so
just one
of your four walls is more or
less covered
with R1s depending on audio
system parameters. Construction
which uses non-parallel walls is
not detrimental to the effect of
the R1, but will not be needed
in a room treated with R1s. Typically,
for a normal room of 5L x 3.5 W x 3H
meters, the total area is 86 m2
and 15 units R1 (15 x 58cm x 58cm)
are just 6.4 m2, meaning
less than 8% !
Optically, your room remains
your initial room and not a
heavy upholstered one as the
concurrence propose you !
As
all the unique and serious
ideas / products the R1 is
the one and only model but has
various industrial or
artistically
paintings
Roundffusor1 is an active gain
(~2dB) clean sound diffuser
(180 - 250Hz to 20.000 Hz) &
an adaptable low frequency
Helmholtz resonator
- highly
efficient like bass trap (5 Hz
to 250 Hz) at levels up to 130
dB SPL.
R1's
Diffusion coefficient is ~1 (the
theoretical limit)
! Even after many hours
of listening to or working with
audio
at such high
levels, the
R1s doesn't let you entering
into the ear fatigue or headache
phenomenon
thus, the
critical audio decisions will be
correct - technically and
musically
Being
an adaptable device, the
diffusion / absorption
parameters follows the ear's
ideal spectral / loudness
curves, from whispers to pain
levels. The room resonances
becomes musical ones. R1 was
successfully tested to real
helicopter recorded
sound! During the test we still
understood each other
making
amazing comments
R1 is 100% Occupational Safety and doesn't expose your breath to porous
particles or fungus, common things in
foam absorptive materials or fiberglass
covered with fabrics, which might
cause allergies or asthma.
More, unlike foam or fiberglass
the R1 will not absorb liquids,
can be easily cleaned, is nearly
indestructible, and will not
retain odors. This makes it a
cleaner, safer alternative. R1
is made from high impact
polystyrene with antistatic
additive, flammability rating
ISO UL94 HB @ 1.6 mm
Historically,
having the R1 on the
market, the idea of
acoustical
treatments was
never that easy and
the results so sure.
The level of aural
sophistication is
incredible.
After listening a
song in a R1
environment, we’ll
never be able to go
back to the old and
obsolete absorption
way, harmful for the
music.
This site is a
complex description
of what R1 is doing. Believe it or not
...
R1
is the World's
Most Efficient
All in One
Acoustical
Diffuser Device
and The Real Acoustical
Reference of The Music Industry
& High End field.
R1 is produced by ESR
Acoustics and is Granted with a
United States Patent
and European Patent
Affordability?
R1 costs
LESS
than any other acoustical material ! The obvious advantage of an
invention way ahead of its
time
