Connecting speakers via cable

16 March 2022

Anyone who buys new good speakers like our GRAND ORCHESTRA or the ORCHESTRA for their hi-fi system must inevitably ask themselves the questions: What is the best way to connect my speakers to my receiver? Which cable do I need to connect my speakers? How long and how thick should the speaker cable be? Because the question of cabling is not unimportant. In fact, it makes a lot of sense to include sensible cables in your budget before you buy. The cables do not necessarily have to be expensive, but good cables provide audibly better sound for small and large systems.

In a hi-fi system, the receiver controls each speaker with its own electrical signal. If this is done by cable, then two copper wires (strands) transmit the signal. The stranded wires are not solid wires, but consist of many individual thin copper wires that are coated with plastic, usually silicone, except for the ends. The signal flows on the surface of the strands.

What is the optimum length for loudspeaker cables?

Basically, the shorter the cable path, i.e. the length of the cable, the better. Because every "metre" of cable inevitably leads to a loss of signal. But don't worry, you don't have to place your speakers directly next to the receiver because of this. With high-quality cables, nothing can be heard of the distance. In addition, the speakers must be a certain distance apart to allow spatial listening. A common recommendation is to use speaker cables with a diameter of at least 2.5 mm² for cable lengths of five metres or more. By the way: The cables should be the same length, because different lengths produce different resistances.

Connect the loudspeaker cables correctly

At least as important as the wiring is the correct connection of the cables to the speakers. During installation, make sure that the cable is screwed tightly to the loudspeaker and amplifier. The cable "settles" in the terminals over time. It will wear out a little. Therefore, it is best to retighten the cable after one or two months.

In addition, the plus terminal (red) on the amplifier must also be connected to the plus terminal on the loudspeaker and minus (black) to minus. If plus and minus are reversed, the speakers will play in the opposite phase. The bass becomes unclean as a result. To avoid this, we like to use the labelled cable side as plus as a little mnemonic, as usually only one side is labelled.

Last but not least, a little safety tip: Only remove or connect cables when the amplifier is switched off. Otherwise there is a risk of a strong noise impulse that can damage the speakers.

Conclusion:

The topic of cables is discussed with much passion in the hi-fi world. If you pay attention to the above-mentioned aspects, you can achieve a very good sound without much effort and expense. So you should not be put off by this. By the way, when you buy our ORCHESTRA in our online shop, we already include matching cables from the German manufacturer Goldkabel.

It is best to seek advice from a hi-fi expert in your area. They can address your individual situation and thus achieve the best possible result. You can easily find sonoro dealers in your area in our dealer search.
