ROOM AND SOUND
Thank you for purchasing ONIX products! We believe you will enjoy wonderful
audio experience from this speaker quite much. First, we would like to suggest you
might keep the carton and cloth bag for future possible shipping use.
Onix Concerto 1 focuses first on outstanding 2-channel sound staging, imaging,
and balance, with additional crossover optimization suitable for reference multi-
channel systems. Intended to bridge the gap between the traditional listening room
and the dedicated home-theater, the Onix Concerto 1 promises to offer performance
and quality beyond your highest expectations.
Try to put your speaker along the long wall. Hard surface acts as reflectors of
high frequencies. Uncovered floors, windowpanes and mirrors can dramatically
affect the distribution of the higher frequencies. Obviously, if you detect reflections
(loss of desirable stereo effect) of the higher frequencies and you suspect the floor
may be responsible for it, placing a rug on the floor close to the speakers may solve
the problem. If the window causes the reflections, drapes should help.
In the other side, the floor and walls act as extension of the speaker. They
generally affect low frequency response. Placing the speakers in the corner of a
room gives maximum bass response. Also with the speakers on the floor, maximum
bass response is obtained. Bringing the speakers away from the walls decrease
bass.
The distance between the two speakers should be approximately as long (rather
a little bit shorter) as the distance between the speaker and the listener. In addition to
possible imaging improvements, toe-in can also change your speaker's tonal balance.
Enjoy experimenting!
CONNENTIONS
All connections should be made with the amplifier POWER OFF and the
volume control set to zero.
Onix speakers feature two pair of heavy-duty gold-plated speaker
terminal for connecting the speaker cable from your amplifier. The loudspeakers can
be connected with every high-class amplifier and power amplifier. When connecting
the speaker with the amplifiers, make sure that the positive terminal of the amplifier
is connected with the positive terminal of the speaker (red color) and accordingly that
the negative terminal of the amplifier

POSITION
In order to obtain a natural music reproduction, please take care that the distance
between Reference speaker and back wall is at least 30cm. further more, at least
50cm between monitor and sidewall. The distance between the two speakers should
be at least 150cm (must no less!).
ATTENTION !
All drivers in the Onix Evolution 2 loudspeakers can handle large dynamic peaks
of power without damage.
However, damage may occur when the speakers are operated from those
amplifiers that are highly distorted. Usually, some low power handling amplifiers are
very easily driven into clipping levels. Even though the amplifiers are low power,
the distorted waveforms can cause damage more so than high power handling

wire, pins or spade plugs, simply unscrew the terminal's end cap to expose the hole
in the center of the shaft. With banana connectors, you don't have to unscrew the

SERVICE INFORMATION
Loudspeakers are inherently reliable and rarely give trouble. It is important to
remember that faults arising in any part of the audio system will be heard via the
loudspeakers and therefore when faults occur, careful and analytical diagnosis will
be required to locate the actual source of trouble.
Loudspeakers cannot generate hiss or hum. Spurious noises of this type
generally originate in the electronics sections of the equipment or even in the
programmed source itself. Faults in a loudspeaker will be audible on all programmed
A fault that is evident only when playing discs but not, for example, when using
the radio tuner, it not likely to originate from the loudspeakers.
Service problems should be discussed in the first place with the dealer from
whom the loudspeakers were originally purchased. Generally, your dealer best
handles warranty claims. Please always feel free to contact our Customer Service
Department.
Thank you, again!
