What is Bi Wiring?

When connecting speakers the term bi-wiring regularly. But what exactly does it entail and does it actually provide an audible improvement? In this blog we explain what bi-wiring is, how it works and whether it is worth applying.

What is Bi Wiring?
Bi-wiring means that a speaker is connected to an amplifier with two separate cables, instead of one standard speaker cable. This is only possible with speakers, such as those from the Elysian- and EVO 4-series, which have two pairs of terminal blocks: one for the highs and one for the lows.

In a traditional connection, both the low and high frequencies run through the same cable. With bi-wiring, this is split: one cable carries the low frequencies and the other the high. This could theoretically result in less interference between the frequencies and a clearer sound.

Does bi-wiring have advantages?
Bi-wiring is often mentioned as a simple upgrade for better sound quality, but opinions are divided. Possible advantages include:

• Less interference: Because low and high frequencies remain separated, there should be less interference between the signals.
• Better detailing: Some experience a more open and spacious sound.
• Improved dynamics: In some cases the music may sound a little more lively.

However, the effect depends on several factors, such as the quality of the speaker cables, the amplifier and the speakers themselves. Some audiophiles swear by it, while others hardly hear any difference.

So what is bi-amping?
Bi-amping is similar to bi-wiring, but instead of two cables running from one amplifier, two separate amplifiers are used: one for the bass and one for the treble. This theoretically offers a greater improvement than bi-wiring, because each amplifier can focus entirely on a specific frequency range. This reduces distortion and can produce a more powerful, detailed sound.

Is bi-wiring worth it?
Bi-wiring is relatively easy to implement, as long as the speakers and amplifier support it. However, don't expect miracles; the effect varies per setup. If you really want a step up in sound quality, investing in better speaker cables or even bi-amping can yield more.
