Additional resistance has an increasingly negative effect on sound quality of a speaker. The sound becomes less dynamic, the definition
of the bass frequencies can be reduced and, in more extreme cases, the high frequencies can be attenuated. Amplifier power is wasted in
the wire, reducing the maximum power output of the system.

Running Speaker wires
Each BluCube loudspeaker will require a separate two-core speaker cable run from the speaker to the chosen location of your amplifier.
In the case of the CXC-650-S and CXCL-650-S (a single-stereo loudspeaker incorporating both left and right channels) you must treat this
as a pair and run two 2-core speaker cables from the speaker to the amplifier.
Running cables during a renovation or a new construction project is obviously more straightforward than running cables after decora-
tion has been completed. Here are some thoughts on how to make the wiring easier and most discrete.
Are you using a regular infra-red controlled amplifier?
An infra-red controlled amplifier requires line of sight between the infra-red remote control and the infra-red receiver. This means the
amplifier needs to be on display or an infra-red extender needs to be used to relay the infra-red signal to the amplifier. The location of the
amplifier in this case is determined by the control system and is thus less flexible in terms of the cable runs.
Are you using a wireless-controlled amplifier?
If you use a system such as Sonos®, that uses wireless technology for remote control and audio distribution, you can position the ampli-
fier in a location that minimises cable runs as well as the disruption to the decor of your property. For example, in the case of Sonos®,
you could locate the amplifier in a cupboard, adjacent room, or even the attic. This is because the amplifier does not need to be visible in
order for it to be controlled as it is controlled and receives the audio content wirelessly. For more information visit www.blucubespeak-
