Are you looking to wire your speakers with 4 terminals but not sure where to start? Look no further! In this article, we will guide you through the process of wiring your speakers with 4 terminals, step by step.
First, let’s clarify what we mean by 4 terminals. Some speakers have two sets of terminals on the back, labeled A and B, with each set having a positive (+) and negative (-) terminal. This means that you can connect two separate sets of speakers to one amplifier or receiver. To wire these speakers correctly, you will need to connect the positive terminal of set A to the positive terminal of the amplifier, and the negative terminal of set A to the negative terminal of the amplifier. Repeat this process for set B.
However, some speakers have four terminals on the back, with two positive (+) and two negative (-) terminals. This can be confusing, but it’s actually quite simple to wire. In the next section, we will explain how to wire speakers with 4 terminals correctly to ensure optimal sound quality.
Understanding 4 Terminal Speakers
If you’ve ever come across a speaker with four terminals, you may have wondered what they are for. These speakers are known as four-terminal or bi-amp speakers, and they offer a unique way to connect your audio system.
What are 4 Terminal Speakers?
Four-terminal speakers have two sets of input terminals – one for the woofer, and one for the tweeter. By separating the inputs, you can connect each driver to a separate amplifier channel, which is known as bi-amping. This allows you to fine-tune the sound of each driver, resulting in a more precise and detailed sound.
How to Wire 4 Terminal Speakers
Wiring four-terminal speakers can be a bit more complicated than traditional speakers, but it’s not too difficult once you understand the basics. Here’s how to wire them:
- Connect the positive terminal of the amplifier to the positive terminal of the woofer.
- Connect the negative terminal of the amplifier to the negative terminal of the woofer.
- Connect the positive terminal of the tweeter to the positive terminal of the second amplifier channel.
- Connect the negative terminal of the tweeter to the negative terminal of the second amplifier channel.
It’s important to note that not all speakers with four terminals are meant to be bi-amped. Some speakers, like Klipsch’s “Height” speakers, have an additional driver built-in, and the extra terminals are meant for that driver.
Benefits of 4 Terminal Speakers
Bi-amping your speakers can offer several benefits, including:
- Improved sound quality: By separating the inputs, you can fine-tune the sound of each driver, resulting in a more precise and detailed sound.
- Increased power handling: By using two amplifier channels, you can increase the power handling of your speakers.
- Flexibility: Bi-amping allows you to experiment with different amplifiers and configurations, giving you more flexibility in your audio system.
four-terminal speakers offer a unique way to connect your audio system, and bi-amping can offer several benefits. If you’re looking to take your audio system to the next level, consider giving bi-amping a try with a set of four-terminal speakers.
Types of Speaker Terminals

Understanding Bi-Wiring and Bi-Amping
If you have a set of speakers with four terminals, you may have heard of bi-wiring and bi-amping. These are techniques that involve using separate cables and amplifiers to power different parts of the speaker. Here’s a brief overview of what bi-wiring and bi-amping are and how they work.
Bi-Wiring
Bi-wiring involves using two separate cables to connect the amplifier to the speaker’s four terminals. One cable is used to carry the signal to the speaker’s woofer, while the other cable carries the signal to the speaker’s tweeter. By separating the signals, bi-wiring can reduce interference between the two drivers and improve the clarity and detail of the sound.
To bi-wire your speakers, you’ll need to remove the metal bridge or jumper bar that connects the two positive terminals and the two negative terminals. Then, connect a separate cable from the amplifier to each of the four terminals on the speaker. Make sure to keep the positive and negative cables separate and connect them to the correct terminals.
Bi-Amping
Bi-amping takes bi-wiring a step further by using two separate amplifiers to power the speaker’s woofer and tweeter. This allows you to tailor the power and frequency response of each driver to better match the speaker’s characteristics and the room’s acoustics.
To set up a bi-amping system, you’ll need two amplifiers, each connected to a separate set of speaker terminals on your receiver or preamp. You’ll also need to remove the jumper bars on your speakers and connect separate cables from each amplifier to each set of terminals on the speaker.
Bi-Wiring vs Bi-Amping
While bi-wiring and bi-amping can both improve the sound quality of your speakers, they are not always necessary or appropriate for every system. Bi-wiring is a simpler and less expensive option that can provide noticeable improvements in sound quality, especially if your speakers have a complex crossover network.
Bi-amping, on the other hand, requires more equipment and setup time, but can provide even greater improvements in sound quality and more precise control over the speaker’s sound. However, bi-amping is usually only recommended for high-end systems or speakers with very demanding power and frequency requirements.
