Congratulations on your new Ilumnia speakers.
These speakers incorporate the unique LEMS technology only found in Ilumnia loudspeakers.
However, this technology requires some extra attention from its owner.
To enjoy them to their fullest potential, today - and for years to come - it’s imperative to invest a
little bit of your time to read this manual. It contains valuable information on how to get the most
out of your high-tech speaker system, how to handle and maintain them properly, and last but not
least, how to listen to them. We’re sure you won’t regret.
Enjoy!

Information
Unpacking
These speakers were carefully tested and inspected during production and before packaging and
shipping. After unpacking please check for any damage. It is rare that a unit is damaged during
shipping, but if this does happen contact your retailer immediately.
Due to the specific nature of these speaker’s geometry the necessary attention has to be given to
unpacking / repacking.
UNPACKING
Follow these steps :
WARNING : Avoid touching the cone during these operations!
1. Place the carton box flat (horizontal) on one of its sides so that the bottom of the box is
accessible.
2. Open the bottom of the carton box by folding the carton flaps 270° up so that the content
can slip out (as described in step 4)

User manual V1.0.2
3. Place the carton back up so that the Ilumnia logo is in horizontal position and the “UP” arrow
is pointing upwards to the ceiling.
4. Now lift the carton box slowly upwards so that the speaker including its EPS packaging slips
out of the carton box from the bottom. Watch out not to tip over the speaker.
5. Now carefully lift of the top part of the EPS packaging.

6. Remove the other EPS packaging parts from the speaker.
7. Remove the protection bag from the speaker
8. Remove the fixing foam part between tweeter and LEMS driver gently by sliding it from the
phase plug.
Do not break or throw away this protective piece. Otherwise it will be impossible to further
handle or ship the speakers as the cone must stay at all times at its rest position while the
speaker is being handled or shipped!
For repacking follow these instructions in reverse order.
RECOMMENDATION
We strongly recommend that you keep the original carton and EPS packing material for future use
and shipping. It has been 3D shaped to optimal protect the speakers against shipping damage.
It’s virtually impossible to ship the speakers safely in any other packaging material.
Remark
:
A green foam ring is somet
imes used
to fixate the cone. Remove this ring before
using the speakers.

Recommended Speaker Setup
1. Placement
Correct speaker placement has a huge impact on sound quality. Every room has its optimal layout for
positioning the speakers and the listening position.
In this part of the manual we will give you some guidelines to position the speakers but the result of
these guidelines will strongly depend on your rooms acoustical properties and dimensions. We do
suggest you experiment with a few different locations and see which setup best suits your taste.
Even half of an inch can make a huge difference in performance, especially when focusing and sound
staging capabilities are involved.
For the best bass response we recommend that you keep a minimum distance of 10-30 cm (4” to
12”) between the speakers and the rear wall. For height, position the speakers with the tweeters at
eye level of your most common listening position. This is important for correct placement of the
soundstage.
Ideally we recommend a distance of about 2,5 till 3 meters (8 - 10 feet) between the 2 speakers.
The distance from the speakers to the listening position should be between 1 and 1,5 times the
distance between the speakers to obtain the best sound staging and imaging. We personally prefer 1
time the distance instead of 1,5. But depending on room acoustics, dimensions and also personal
taste it can be a good idea to experiment by adding 0.5 to 1 meter (1 - 3 feet) additional distance.

2. Bass Ports
The Ilumnia Vocalis MKII has an adaptable bass reflex back loaded port. This port constitutes of 2
parts, the inner and outer tube. To change the tuning of its frequency you can shove the inner tube
backwards or remove it completely.
Frequencies of the bass reflex port at different settings of the inner tube :
For associated frequency responses see p.15
Inner tube shoved inwards 4cm (1,5 inch) : 46 Hz
Inner tube at the same height as the outer tube : 49 Hz
Inner tube removed : 51 Hz
WARNING : DO NOT BLOCK THE BASS REFLEX PORT OF THE VOCALIS AS THIS WILL BLOCK
VENTILATION TO THE INTEGRATED POWER SUPPLY

User manual V1.0.2
3. Speaker Conditioning and Break-in
Although a break-in period is not required, we recommend that you play between 100 to 150 hours
of music through the speakers before doing any critical listening or speaker placement.
The LEMS driver does not have a break-in period at all because it does not have any parts which are
prone to strain like spider and surround. But the Scanspeak tweeter and the filter parts do.

Speaker Cleaning
DISCLAIMER : Ilumnia BVBA cannot be held responsible for damage caused to the speaker drivers by
any of the procedures described in this user manual. Physically touching the cone always involves a
certain risk of damaging it and the only way to avoid damage is by not touching it at all. Damage
caused by physical contact with the cone always voids warranty and is not covered by the limited
warranty.
Don't use any solvents or cleaners on cabinets, aluminium parts or speaker drivers.
As already mentioned in the disclaimer we do not encourage customers to touch the cone of the
LEMS driver. But if there’s excessive dust on the LEMS driver and cleaning is really necessary follow
these guidelines :
 Try to clean the cone just by gently blowing off the dust (do not use high pressure tools!!)
 If this doesn’t help wipe down with a soft, dry cloth. Ideally use a clean and unused SWIFFER
DUSTER pad or soft micro fiber cloth. Never use moist or any form of liquids as the cone is
made of impregnated paper!
 When cleaning, don’t use pressure to the cone to avoid deforming the cone or the
aluminium closing ring.
 Avoid the cone being turned around its center as this movement can damage our
proprietary flatband litz wire which is mounted underneath the cone (not visible).
Clean the cone from the inside to the outside, see picture.

If there’s a hint of scraping / scrubbing sound coming from one of the LEMS drivers.
First thing to do : DON’T PANIC, it’s not broken
Most probably a tiny piece of dirt or excessive dust has nested between the outside of the aluminum
closing ring of the cone and the inside of the outer chassis ring of the driver.
The tolerance between these two parts is kept to a minimum in order to avoid acoustic short circuit.
But there is still a very narrow air gap and we cannot 100% exclude that dirt or dust can fall in
between. In practice, if dust or dirt fits in between it also falls through and doesn’t get stuck. But
during testing under severe circumstances (sun, moist, dust) we once simulated this particular
problem with a sticky kind of dirt.
So, if this problem should occur (dust or dirt gets stuck) you can easily fix this problem yourself.
Dirt

Ilumnia Vocalis

User manual V1.0.2
Procedure :
Take an ordinary piece of paper (such as normal 80 grams print paper but don’t use any stiff paper
like thick photo quality print paper). Cut a slice of it (see picture) and move it between the cone and
the outer chassis ring of the driver (see picture). Go all around the cone and at the same time hold
the cone steady with your hand so it won’t turn around!. The piece of paper will push the dirt to the
surface or in some cases it will fall in the decompression chamber located underneath the aluminum
closing ring.
There is no harm in dust or dirt falling into the decompression chamber. It has been designed with
sufficient clearance between cone and bottom.

1. Power On / Off
 This switch is used to power off the speakers completely. For instance when you are
planning not to use them for several days (i.e. holiday) or before disconnecting them
from the power supply unit. Before disconnecting the speakers from the wall outlet
ALWAYS wait until the complete powering off sequence has finished (+/- 40min) and
the cone is in its resting position. There can be occur a slight difference in time
between the left and right speaker.

Playing music
STEP 1
Switch on both Ilumnia Vocalis speakers at the back of the speakers.
Remark : if the speakers are switched off only the tweeters will work. This is done to protect the
LEMS driver against music signal being fed while the cone is not floating (off position). The tweeter is
never cut-off to keep a minimum load for the amplifier (this is done to protect tube amplifiers against
being played without load).
Power consumption “ON” : 6 watt
IMPORTANT NOTE : These speaker have an active electromagnetic field to float the cone. This field
also creates a limited amount of heat. The engine of the driver needs to be at a temperature of at
least 25° Celsius or higher to perform optimal. After being switched on, this corresponds to a warm-
up time of about 30 minutes from cold (depending on room temperature). The pole piece and phase
plug of the LEMS driver have been designed for an optimal temperature control of the driver. After
some time you will feel it’s a little bit warm (lukewarm). This means the speakers have reached their
optimal operating temperature.
