Connecting multiple column speakers together can significantly enhance the audio coverage and quality in various settings, whether it's a large auditorium, a retail space, or an outdoor event area. As a column speakers supplier, I've witnessed firsthand the benefits and challenges that come with this process. In this blog post, I'll guide you through the steps and considerations for successfully connecting multiple column speakers.
Understanding Column Speakers
Before diving into the connection process, it's essential to understand what column speakers are and how they work. Column speakers are long, narrow speakers that typically consist of multiple small drivers arranged vertically. This design allows for a more focused and controlled sound dispersion, making them ideal for applications where precise audio coverage is required.
There are different types of column speakers available in the market, each with its own characteristics and specifications. For instance, 8 Ohms Low Impedance Column Speakers are commonly used in low - impedance audio systems, where the speakers are connected directly to an amplifier. These speakers are suitable for small to medium - sized venues where high - power output is not always necessary.
On the other hand, Column Line Array 70V Speakers are designed for distributed audio systems. They operate at a constant voltage of 70V or 100V, which allows for easy connection of multiple speakers over long distances. This type of speaker is often used in large commercial spaces, such as shopping malls and airports.
Planning Your Setup
The first step in connecting multiple column speakers is to plan your setup carefully. Consider the following factors:
Venue Size and Layout
The size and layout of the venue will determine the number and placement of the column speakers. For a large, open space, you may need more speakers to ensure even audio coverage. In a smaller, more confined space, fewer speakers may be sufficient. Measure the dimensions of the venue and identify any areas that may require special attention, such as corners or areas with high noise levels.
Audio Requirements
Think about the type of audio you'll be playing and the desired sound quality. If you're hosting a live music event, you'll need speakers that can handle high - power output and reproduce a wide range of frequencies accurately. For background music in a retail store, the requirements may be less stringent.
Amplifier Compatibility
Ensure that your amplifier is compatible with the column speakers you've chosen. Check the impedance and power ratings of both the amplifier and the speakers. Connecting speakers with the wrong impedance to an amplifier can damage the equipment and result in poor sound quality.
Connecting Low - Impedance Column Speakers
If you're using low - impedance column speakers, such as the 8 Ohms Low Impedance Column Speakers, the connection process is relatively straightforward.
Series Connection
In a series connection, the positive terminal of one speaker is connected to the negative terminal of the next speaker. This increases the total impedance of the speaker system. For example, if you connect two 8 - ohm speakers in series, the total impedance will be 16 ohms. However, it's important to note that series connection also reduces the power delivered to each speaker.
To connect speakers in series, follow these steps:
- Turn off the amplifier and unplug it from the power source to avoid any electrical hazards.
- Connect the positive terminal of the first speaker to the positive output of the amplifier using speaker wire.
- Connect the negative terminal of the first speaker to the positive terminal of the second speaker.
- Connect the negative terminal of the second speaker to the negative output of the amplifier.
Parallel Connection
In a parallel connection, the positive terminals of all the speakers are connected together, and the negative terminals are also connected together. This decreases the total impedance of the speaker system. For example, if you connect two 8 - ohm speakers in parallel, the total impedance will be 4 ohms. Parallel connection allows each speaker to receive the full power from the amplifier.
To connect speakers in parallel, follow these steps:
- Turn off the amplifier and unplug it from the power source.
- Connect all the positive terminals of the speakers together using speaker wire. Then, connect this combined positive connection to the positive output of the amplifier.
- Connect all the negative terminals of the speakers together using speaker wire. Then, connect this combined negative connection to the negative output of the amplifier.
Connecting 70V Column Speakers
Connecting Column Line Array 70V Speakers is a bit different from low - impedance speakers. These speakers are designed for use in a constant - voltage audio system.
Using a 70V Amplifier
First, you'll need a 70V amplifier. These amplifiers are specifically designed to drive 70V speakers. The amplifier has a 70V output terminal that you'll use to connect the speakers.
Speaker Taps
70V speakers usually have multiple taps that allow you to adjust the power delivered to the speaker. These taps are labeled with different power ratings, such as 1W, 2W, 5W, etc. Select the appropriate tap based on the desired volume level and the distance of the speaker from the amplifier.
Connection Process
- Turn off the 70V amplifier and unplug it from the power source.
- Connect the positive and negative terminals of the first speaker to the 70V output of the amplifier using speaker wire.
- For additional speakers, simply daisy - chain them together. Connect the positive terminal of the first speaker to the positive terminal of the second speaker, and the negative terminal of the first speaker to the negative terminal of the second speaker.
- Adjust the speaker taps on each speaker to achieve the desired volume level.
Installation Considerations
Proper installation of the column speakers is crucial for optimal performance. Consider the following points:
Mounting
Column speakers can be mounted on walls, ceilings, or stands. Choose a mounting option that provides a stable and secure installation. Make sure the speakers are mounted at the correct height and angle to achieve the desired sound dispersion.
Cable Management
Keep the speaker cables organized and away from other electrical cables to avoid interference. Use cable clips or conduits to secure the cables and prevent them from being damaged.
Installation Column Speakers

Testing and Troubleshooting
Once you've connected and installed the column speakers, it's time to test the system.
Power On and Volume Check
Turn on the amplifier and gradually increase the volume. Listen for any unusual sounds, such as distortion or humming. If you hear any problems, turn off the amplifier immediately and check the connections.
Audio Coverage
Walk around the venue to check the audio coverage. Make sure the sound is evenly distributed and that there are no dead spots. If you notice any areas with poor audio quality, you may need to adjust the speaker placement or the volume settings.
Troubleshooting
If you encounter any issues, such as no sound or low volume, check the following:
- Ensure that all the speakers are properly connected and that the cables are not damaged.
- Check the amplifier settings, including the volume, gain, and impedance settings.
- Make sure the power supply to the amplifier and the speakers is stable.
Conclusion
Connecting multiple column speakers together can be a rewarding process that significantly enhances the audio experience in your venue. By understanding the different types of column speakers, planning your setup carefully, and following the proper connection and installation procedures, you can achieve excellent audio coverage and quality.
