Music may be enjoyed by a wide range of people thanks to speakers. There are a variety of speakers on the marketplace, but they are all wired and connected in the same manner. The wires, on the other hand, maybe extremely intimidating, particularly if many terminals are involved. People are curious about how to connect speakers with four or more terminals because of this.  In the following blog post, we will see how to wire speakers with 4 terminals, how to hook up paradigm speakers, and also learn about the tweeter wiring diagrams…

How To Wire Speakers With 4 Terminals?

Since bi-wiring is the most popular configuration, most speakers contain two sets of terminals. These solutions have the ability to improve the sound and quality of your speakers. Multiple terminals, on the other hand, just indicate that the speaker may be “bi-amped.” If you purchased speakers with four terminals, follow these steps to connect them or bi-amp them:

Step 1: Turn off your speakers

Check to be that the complete system of your speaker is turned off before continuing.

Step 2: Remove the bi-wire bridges

The bi-wire bridges should be carefully removed from the speaker. This is where the LPF and HPF crossovers and disconnect the high and low-frequency crossover networks of the crossover network.

Step 3: Connect amplifier channels

It’s important to connect each amplifier channel to its corresponding speaker component. The receiver will now be set to bi-amp mode.

Step 4: Locating the terminals

You may find the bi-amping terminals on the back of your receiver by looking at the rear of the receiver.

Step 5: Adjust the control levels

Set the volume settings on the amplifier so that the signal sent to your speaker has the same amount of loudness as the signal received from the amplifier.

Note: If the amplifiers are identical, all that is required is that the amplifier level controls be set to the same value.

Step 7: Connecting some speakers

Hook the left speaker’s set of connectors to the receiver’s front (primary) speaker output. Repeat the process on the opposite side. The wiring is now complete.

What is Bi-Amping? 

Bi-amping is the same as knowing how to connect speakers with four terminals. By assigning high-frequency and low-frequency speakers to their respective amplification channels, this method isolates the frequency sounds. Bi-amplifying has four terminals instead of two, which allows for more control and better sound. That is why many people have shown that bi-amping is perfect for home theatre since it always affects the sound that your speaker produces.

The audio quality increased when the speaker was bi-amped, particularly when music and movies were played. You must understand that if the sound is demanding, the power provided to each speaker might result in less constricted and improved sound. Furthermore, understanding how to connect speakers with four terminals provides you the option of purchasing a large number of amplifiers to power the speakers.

The procedure of bi-amplifying is similar to that of bi-wiring, with the exception that you must power amp both sets of terminals. Unlike bi-wiring, which only has two sets of terminals in the speaker, it contains four sets of terminals. You must therefore set terminals you connect into when bi-amplifying, resulting in higher and clear sound.

Which Speaker Terminals To Use?

In order to connect the positive speaker terminal (red) on the receiver or amplifier to the positive speaker terminal (red), all of the equipment must have the same connection. Essentially, the color or marking of the wires is irrelevant as long as the terminals are all the same. However, it’s typically a good idea to follow the signs to prevent misunderstanding in the future.

The term “in phase” refers to the fact that both speakers are working at the same time. In this case, the speakers are said to be “out of phase” since one of the connections is inverted (i.e., positive to negative rather than positive to positive). This may have a negative impact on audio quality. It’s possible that nothing is harmed, but you’ll probably notice a change in the result, such as:

  • Bass that sounds thin and lean, or subwoofer performance that isn’t up to par, or both.
  • There is no discernible image in the middle.
  • A broad feeling that something isn’t quite right about the system.

No doubt, other faults may cause comparable sound difficulties, but one of the most typical blunders when setting up a stereo system is having the wrong speaker phase. Sadly, it’s easy to ignore the Speaker phase setup, particularly if you’re working with a tangle of audio and video wires.

As a result, take your time to double-check that all speakers are in sync: positive-to-positive (red-to-red) and negative-to-negative (black-to-black).

Tweeter Wiring Diagram    

Tweeters are speakers that generate the high-frequency sound that is heard in music. Due to the fact that higher sound frequencies produce smaller sound waves, they are smaller in size than the speakers with which they function.

A tweeter is a kind of electromechanical loudspeaker that generates sound and music at higher frequencies. They work in conjunction with woofers and other speakers that are incapable of producing higher-pitched sounds, such as those found in a two-way bookshelf speaker pair arrangement.

Tweeters are modest in size due to their lower soundwaves and conical shape. Generally, they work best when directed at the listener. Most are confined to a set frequency range, such as 3 kilohertz to 20 kilohertz (kHz), however, this varies depending on the speaker. Human hearing is typically between 20 Hz and 20kHz.

How To Connect 4 Conductor Speaker Wire To Speaker?

If you just have one set of terminals, simply connect the speaker’s red and black wires to the amplifier’s red and black wires. Allow white and green to exist in isolation. You may use them later if you get bi-wired speakers to replace the existing bi-wired speakers. Red indicates positive, whereas black indicates negative.

Let’s assume you’ve purchased KEF. When the KEFs arrive, if they are bi-wired, attach red and black to the LF pos/neg terminals and white/green to the HF pos/neg terminals. Attach red and white (provided white was linked to positive at the speaker) to positive on the amplifier, and black and green to negative.


Banana plugs – one on each conductor at the speaker end, and two conductors to each banana at the amplifier end. Ascertain that the plugs are large enough to accommodate both conductors. Assure that you have enough plugs (4 on the amp + 4 on the MKs + 8 on the KEFs) = 16
