Painting the speakers and grilles.
Both the speaker frames and the grilles can be painted, if desired. We recommend doing this
before installation to avoid a paint scar or meniscus forming around the frame edge. If the speaker
frame is painted after installation, use the supplied paint mask to protect the speaker drivers
during painting.
Always paint the grilles separately from the speaker itself. The grilles should only be spray painted
and with the use of thinned paint to avoid clogging of the fine mesh of the grille. Thin the paint
with 5 parts thinning agent to 1 part paint.
Only install the speakers and grilles once the paint has dried thoroughly.
Single-Stereo (CXC-650-S) model
The 650-S model uses the same installation procedure as other models but needs two speaker
cables as it produces both left and right channel audio signals from one speaker housing. It is
ideally suited to smaller rooms such as bathrooms. The crossover circuit board on the speaker
features two sets of push-to-connect terminals and it is essential that the correct polarity of the
connections to your amplifier is maintained. If the sound from the speaker lacks definition, it is
highly likely the polarity is incorrect. It does not matter which speaker terminals are connected to
the left or right channel on your amplifier, but the correct polarity is critical.
Setting the Tone Control
Blucube CX-series loudspeakers feature baffle-mounted level controls for both bass and treble
frequencies. The level control will help you to fine-tune the performance of the crossover to meet
any demanding room acoustic issues or listener preferences.
Each level control adjusts an octave wide band of frequencies most affected by the interaction
between the drivers. The controls can be adjusted to provide 3dB of boost or 3dB of reduction on
each of the drivers in any CX-series loudspeaker.
The level controls are able to help you maximise sound quality regardless of room setup and
speaker placement.
Adjusting your speakers
Note: Do not apply pressure to the tweeter dome itself. The pivoting tweeter can be used to direct
sound towards or away from a listening area. To pivot the tweeter, apply light pressure to the
plastic ring around the outside edge of the tweeter.
If your speakers are widely separated and the music fails to blend into a central image when the
system is operated in stereo mode, you should orientate the tweeters toward the listening area.
If you are using your BluCube loudspeakers in a home theatre environment, you can point the
pivoting tweeter towards a wall or window to create a diffuse surround effect.
