When connecting more than one pair of speakers to an amplifier it is vital to ensure that
impedances are matched. Your amplifier will specify an impedance range with which it can
handle and you must ensure you do not drop the total impedance below the minimum level
or you may damage your amplifier. Conversely if the total impedance is too high, sound
quality will be adversely affected. If in doubt you should consult a professional installer or
contact BluCube directly before commencing installation.
As an example, a typical amplifier may specify an operational acceptable impedance range
of 4 to 8 ohms. If you connect two pairs of BluCube Loudspeakers (set to 8 ohm impedance
on the circuit board) in parallel, the impedance you will present to the amplifier is 4 ohms.
This is within limits. If you connect them in series, you will present 16 ohms resistance to
the amplifier which will have a negative effect on sound quality.
If you switch the impedance of your BluCube loudspeakers to 4 ohms and connect two of
them in parallel, then the impedance will be 2 ohms and may damage your amplifier. If they
are connected in series, the impedance will be 8 ohms and therefore within acceptable
limits.
Please note that, much like attaching a trailer to the back of a car, attaching a second set of
speakers to an amplifier will put additional load on the amplifier (or engine). This makes it
work harder for the same performance or it may simply not have the power to perform at all.
You need to check the capability of your chosen amplifier before tackling this.
Home Theatre Placement
When using the speakers as rear channel speakers in a home cinema environment, they
should be ideally located between 0.4 to 1.8m behind the main listening position. They
should be separated approximately 1.8m to 3.0m apart.
Wire Gauge and Quality
A good rule of thumb to consider when installing speakers is that the total wire resistance
should be less than 10% of the speaker impedance. If using an 8 ohm speaker, your wire
resistance should therefore be no more than 0.8 ohms.
The resistance of any wire is directly proportional to its length. So if you double the length,
you double its resistance.
