CENYA
User’s manual

PENAUDIO    Ltd. manufactures loudspeakers in Jyvaskyla Finland from the best materials
available. PENAUDIO loudspeakers are made without compromising the quality of
sound. The loudspeakers are designed based on listening impressions in the actual
listening environment. Measurements are used only to support the listening
impressions or to resolve a problem.
During the development period the listening panel consists of professional as well
as amateur musicians. The listening panel’s comments are valuable in ensuring that
the different instruments sound as genuine as possible.
CENYA          Cenya is a handmade 2-way loudspeaker. Cenya’s crossover filter and even the
internal wiring have been selected after long listening tests under actual listening
conditions. Its sound balance has been tweaked to create seamless full spectrum
response.
Please read the instructions carefully to be able to enjoy the full potential of your
new loudspeakers.
Consider the following instructions in positioning the Cenya loudspeakers.
PLACEMENT
The loudspeakers should not be placed too near the corners of a room or too close
to the back wall. The more space there is around the loudspeakers, the better. In
an optimum situation all the distances are different, measured from the
midrange/woofer to the floor, side wall and back wall. It is useful to experiment
with the positions until you find the perfect ‘stereo image’. There are always some
reflecting surfaces in the room that have an impact on the sound, so the best
placement solution for the loudspeakers may not be symmetrical.
The optimum listening distance of the PENAUDIO loudspeakers is from 2 to 3,5
meters, the distance between the loudspeakers being 1,6 – 3,4 meters. The ‘stereo
image’ is best achieved when there is an equilateral triangle between the
loudspeakers and the listener. This is worth trying to achieve the best result.
Usually it turns out that a wide ‘listening triangle’ creates a wide, but inaccurate
‘stereo image’. On the other hand narrowing the ‘listening triangle’ makes the
‘stereo image’ more accurate but also more limited.
It is worth it to take the time to find the best positioning for the PENAUDIO
loudspeakers. Correctly placed, PENAUDIO loudspeakers produces a real feeling of
space, originating in the record. This creates a wonderful impression of the
presence of the orchestra.
ROOM ACOUSTICS
All loudspeakers are affected by the reflections in rooms. At worst, the reflections
can make the sound shrill and inaccurate. This can be easily minimized with the
help of furniture. For example you could place a bookshelf full of books or thick
curtains behind the loudspeakers. The walls surrounding the loudspeakers could be
decorated with a bookshelf or paintings. The space behind the listener could also
include some of the articles mentioned. It is worth placing a rug on the floor
between the listener and the loudspeaker. The acoustics of the rug can still be
enhanced by placing a thin layer of cell foam under it. The rug prevents most of the

reflection coming from the loudspeakers and the floor. It may also be worthwhile to
move aside the coffee table.
CABLES AND CONNECTING THE LOUDSPEAKERS
Use proper cables with your loudspeakers, because poor cables have a lot of
resistance and inductance that will have a bad effect to the sound. Thickness is
usually a sign of good quality in cables. Also keep the cables as short as possible
and connect them tight. The loudspeaker cables should be connected as follows:
Connect (+) to red marked binding post and (-) to black/white marked binding post.
AMPLIFIER
PENAUDIO’s Cenya have a nominal impedance of 4 ohms and its sensitivity is 86dB
so they are quite easy load for the amplifier. The sensitivity of the loudspeakers is
quite moderate, so it is possible to have more power especially in wooden
structured, spacious rooms and heavily acoustically treated rooms. We recommend
power amplifiers in the 50 – 300 W range.
How to prevent loudspeaker failure.
When amplifiers with low power seem inadequate for the listener, the usual mistake
is to turn up the bass and treble. This magnifies the amplification ten times higher
concluding in the over strained amplifier to feed distorted signal into the
loudspeakers, and ultimately burning the loudspeakers. Another mistake is to adjust
the power too high when the source of the program is a cd player. The cd player
usually reaches its peak at the half way of the power density of the amplifier. If the
power is raised beyond that point, the drivers of the loudspeakers could be
damaged.
GUARANTEE
PENAUDIO loudspeakers come with a five year worldwide guarantee including labor
and material. The guarantee does not include failure due to mistreatment.
