How To Bi-Amp Speakers The Right Way? An Expert Guide

There are a lot of modifications for speakers nowadays. If you are a dedicated audio geek, getting the most out of your audio component is something you always desire. That's why as of now, it is essential for you to know how to bi-amp speakers.

Improving the sound quality can be done by buying expensive sets of speakers. But would you do that? We are not questioning about your spending capacity.

However, will you just immediately replace your current speakers just because you find them lacking? Would you not try other options if they are plausible?

Fortunately, there are several methods for enhancing the performance of your speakers. Specifically, they are bi-amping and bi-wiring. In this article, we will discuss these two. Read on!


Bi-Amping and Bi-Wiring

Although they can optimize the sound output of your speakers, these two methods are not necessary. Instead, wiring and amping your speakers are for those who want to customize or upgrade their setup.

For starters, you should know that speakers have two components. The first one is the bass (or low frequency) and the second is the tweeter (or high frequency).

Why is this basic concept important? Well, both of the bi-wiring and bi-amping methods try to elevate the sound quality by separating the said two components.


The bi-amping method is ideal for isolating various frequency signals. It can be done by giving the low-frequency and high-frequency speakers their respective channels for amplification.

In fact, there are some receivers (multi-channel brands) that will allow you to use four channels independently.

Some audiophiles testified that bi-amping could improve the sound output of speakers. If you are watching movies or listening to music with your friends, then these speakers can seal the deal.

At some point, you will realize like "bi-amped" speakers are like having a four-wheel drive vehicle. In short, it is better to drive on any terrains if you can empower of each of the wheels.

During times of tough demands, powering each of the speakers will result in a less-constricted sound. Moreover, this kind of setup will give you the freedom to purchase various amplifiers to crank your speakers.

Also, the bi-amping technique allows you to look for amps without having to worry about their power rating.

The process of bi-amping is almost similar to bi-wiring. Their only nuance is the setup of the cables that you are going to need.

Specifically, the cable sets from the speakers must be attached to the amplifier's binding post. Of course, you could use multiple amplifiers as we mentioned earlier.

The process is just simple as you just have to connect the respective cables to the binding post. When bi-amping a setup, you must balance the power of the amplifier first. You must also check the power output and frequencies of the speakers as well.

Authentic bi-amping requires you to attach each of your amplifiers to electrical crossover setup. The latter will serve as your replacement to the default crossover network that your speakers have.

In short, you must take out the passive crossover so that you can fully maximize the benefits of bi-amping.

As a result, bi-amping creates an "active crossover" in which connects the amplifiers to their respective terminals on the speakers.

On ordinary setups, the first cable should go to the woofer. Meanwhile, the second one goes through the high and mid frequency terminal.

For 9.1 and 7.1 receivers, you can designate any of its unused channels to the speakers' channels (left and right). Therefore, it is essential to scrutinize the capabilities of your receivers before you start bi-amping.

Meanwhile, bi-wiring is a method that connects the amplifier to your speakers. In conventional setups, you only use one cable to connect the amp to the speakers.

However, similar to bi-amping, bi-wiring requires you to use two cables. One cable is for the bass, and the other one is for the tweeter.

Many people argue that bi-wiring doesn't give any benefits at all since you still connect the cables to similar ports.

Well, we cannot stop them from believing on that. But if you are an audio enthusiast you will hear the difference, especially on the mid-range frequency.

Of course, you should never ignore this aspect. If you don't know, the midrange sound is an essential part of music.

And there is one infallible reason for that: human voice belongs to the same frequency, too. Therefore, the speakers can produce unmuffled audio after you employed bi-wiring to them.

Most speakers that you can see on the market today comes with two binding posts. They are for the low frequency and high frequency, respectively.

Specifically, these binding posts are connected by conductive bars. This kind of design is the reason why you only need a single wire to establish the connection.

The first thing you need to do in bi-wiring is removing the conductive bars. Next, you must attach the wires for each of the terminals of the speaker. Finally, connect the wires to your amplifier.


Learning how to bi-amp speakers is an essential skill for any audiophile. It is a harm-free method for innovating the quality of sound that your speakers can produce.

Moreover, it is pretty cheap compared to buying high-end speakers. Therefore, it is a life-hack that every weekend warrior surely want to master.

But even despite their usefulness, both bi-amping and bi-wiring still receive a myriad of criticisms. Some people think that they are not enough to supplant the quality of high-end speakers.

But as you can see, there is nothing you can lose if you try them on your setup.
