1. GRACIOSO 2.0
The Gracioso 2.0 is a 2-way bass reflex loudspeaker, distinctive by its topmost design and
dramatically realistic sound. Because of its power-handling and sensitivity, it is suitable for most
audio systems. It will fit in midsize to large rooms, sonically and visually.
Each Gracioso 2.0 speaker is a unique and exclusively handmade product. Every pair is
inspected, matched, tested and approved in Acoustic Preference labs before being sent to the
customer.

3. HANDLING
After removing the external covering of packing, grab the housing of the loudspeaker and pull it out
of the packing box together with the protective inner package.
Follow all the enclosed instructions for setting up the loudspeakers.
Figure 1: Protective grills are attached to the speakers with a self-centering magnet system. You can remove them by
gently pulling them away from the speakers. They can be re-attached by bringing them near to their position on the
speaker and the magnets will lock the grills into the right position.
Figure 2: Firmly mount the lower spikes
into the brass sockets in the bottom of
the speaker.
Spikes are height adjustable and allow
levelling of the speaker in the case of
uneven floors.
Figure 3: Remove WBT terminal
bridges if using bi-wire connection.

4. PLACEMENT
All loudspeakers interact with the environment in which they are placed. Loudspeaker performance
is influenced by the size, shape, and contents of the listening room as well as the placement of the
loudspeaker within the room.
The distance between the speakers and the rear wall should, ideally, be between a half and a full
metre. (For the best stereo imaging and a sense of spaciousness, place the speakers at equal
distances from the primary listening position and the side walls; move speakers closer to the
corners or walls of the listening room to increase bass response).
Figure 4: Distance between speakers, listening area and walls
Remove all obstructions between speakers and the primary listening position. For instance, a coffee
table between a speaker and the primary listening position will degrade stereo imaging and timbre.
Placing a speaker near large objects may also cause unwanted reflections.

In home theatre systems, the magnetic radiation of the loudspeakers must be taken into
consideration. It is strongly advised to refrain from placing front loudspeakers closer than 50cm
from your TV.
The distance between the speakers should be slightly less than the distance from the speakers to
the listening area. For the best stereo imaging and sound staging, the listener should be equidistant
from the 2 speakers.
The angle at which the speakers are aimed at the listener will vary from room to room.
We recommend the following two alternatives:
1) Position the speakers parallel to the rear wall (widen the soundstage).
2) Toe the speakers in to aim at the listening area (optimal stereo imaging and timbre).
Experimentation is vitally important to achieve optimum results in any given environment.

5. CONNECTIONS
Turn off all audio system power before making any connections.
Use high-quality loudspeaker cables. The length and type of speaker cable used for your
system will have an audible effect.
Make all connections observing the proper polarity, positive-to-positive (+) and negative-to-
negative (–).
Most speaker cables are marked so that it is possible to distinguish between conductors by
the colour of the insulation or by a white stripe or small raised edge along one conductor. Correct
phasing of the speakers is vital for sound quality.
Connecting your Gracioso 2.0 loudspeakers
1. Connect one pair of loudspeaker wires to the input connectors. Then connect the same pair of
loudspeaker wires to the desired power amplifier output channel.
2. Repeat step 1 to connect the second loudspeaker to a separate power amplifier output channel.
