What is the Roundffusor1 or R1?
The Roundffusor1 is the world's most
efficient acoustical diffuser and self adaptable low frequency
absorber. Self adaptable means that our device filters, from
case to case, the undesirable room responses and lets your
preferred music sound as it was recorded.
Where to use the R1?
The R1 may be used in any High-End or
music dedicated room, home cinema, recording and rehearsal
studios, schools of music, music halls and big multi channels
sound cinema halls, Radio and TV studios and churches.
Don't forget: the sound quality that
you may perceive in any room from a sound installation is more
or less 60% (worst case scenario) to 40% (best case scenario)
Real Room Acoustics and 40% to 60% Sound System dependent.
Simple, but not simplistic, explanations
One way that our Roundffusor1 treats and
solves all room acoustic problems is just this: being
an adaptable low and very low frequency absorber - the
simple masking and dynamic masking phenomena that exist
because of low frequency overloads are reduced so much so that
are not being perceived by the human ear. The same object, the
Roundffusor1, with a minimum area (58x58cm) and only 11cm
depth is simultaneously a powerful wide band diffuser
that solves the difficult problems of room standing waves
creating a diffuse sound field where no sound detail can be
hidden from the listener. It sounds simple but in fact, from a
theoretical point of view is so complicated that the actual
theoretical background level is not enough to fully explain
the Roundffusor1 functions. Research is done by the patent
holder mostly in the psychoacoustical domain, because there
lays the key to its behavior and perhaps the answer.
Until now, even with the f MRI [magnetic
tomography - collateral research and interpretation of work
done by other researchers] we were not able to find much more.
The question that you must ask yourselves is the following:
What is more important, to have a real device that works
independent from the theory or to obey the ''absolute'' theory
which at the moment is not practically applicable in so many
The Roundffusor1 is patented and its design and function
are indeed original. The native Romanian designer, Zainea
Liviu, who has been living in the last 24 years in Greece, was
influenced in its design by the purity and simplicity of
ancient Greek art. It is a known fact, as archaeology unveiled
the past, that ancient Greeks used no absorptive materials in
their theatres, just hard materials and ingenuity, and we all
know the great acoustics the ancient Greek theatres posses.
Through critical measurements, we can provide any
interested party, we can show that the R1's plastic body
doesn't vibrate, therefore it doesn't produce second
generation sound harmonics.
can show that the cavity from the R1's back Helmholtz
resonator is having a double role -adaptable for low and very
low frequencies up to 181 Hz and beyond this, while the mid
and high frequencies are drastically damped [only from the
R1's inside] about 10 to 25 dB. This explains the dramatically
perceived and, most important, measurable RT60'S reduction
in empty rooms containing only the R1 which negate the need
for further acoustic treatment, reducing the costs of building
a "perfect" acoustical studio environment drastically.
The front R1's surface , don't forget, is producing the clean
diffused field like no other device in the market today,
enhancing the room's loudness field by a factor of 1,5 -2 dB.
This is a paradox, but don't forget that in this life and
universe, the good luck or randomness plays a constructive
role, name it evolution, sometimes, as in the Roundffusor1's
case were a design progression of interrelated phenomena
evolved in this patent. Or, if you prefer, stay put in the
