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.
