A connection between a computer and a 4 ohm speaker is not a big deal as many think. Provided you have a well-functioning 4 ohm speaker, there are higher chances that the connection will be successful and no fault can happen, so you don’t need to worry about that.
The favorite part is that it is very simple to use a 4 ohm speaker connected to a computer since you have only to understand the impedance of the speaker we are connecting to the computer.
Furthermore, my article below is of importance if you follow the instructions I give carefully. After grabbing the concept, your connection is done within minutes and properly working. Don’t fail to check frequently asked questions and the conclusion.
How to use a 4 ohm speaker connection on a computer
To use a 4 ohm speaker connected to a computer, you have to understand some basic knowledge on how the speaker and its ohms relate to a computer. The first thing is the speaker’s impedance, then testing the speaker or even looking at the specifications. Don’t miss reading the procedures before setting up your connection.
Two procedures to enable a 4 ohm speaker connection on a computer;
| Procedures to follow | functions | Essential products |
| Testing the speaker using multimeters and 9 volts battery | acquire accurate results | Check the best multimeters from Amazon. 9v battery |
| Impedance of the speaker | to get resistance applied |
1. Testing the speaker
There are different ways of testing the speaker, and so to achieve it successfully, use the following methods below:
i. Disconnect the speaker
Terminating the connection between the speaker and the amp is the first step before proceeding to any connection for safety. Many different computers are connected to the amp in different forms.
Some speakers use cable connecting, which you can connect using the same cable, two being terminal receptacles you just cut off the terminals and the soldered cables you have to melt it down. Once the disconnection is achieved, you are good to test.
ii. The two ways of testing the speaker are using a battery and a multimeter. In many instances, a multimeter is more accurate than a 9v battery, and remember, these two methods are only used for lower frequency or mid-range speakers, which works best for a computer.
- Using a battery
Though, it’s not the accurate method to get the desired results. A The battery connects to the terminals (negative and positive terminals) then perfectly attaches the speaker’s terminal.
- Using a multimeter
This gadget acquires accurate results that help you get the best results. Having a 4 ohm speaker for our case, the measure of resistance between 2-3 ohms, then remember if the speaker reads low, it is worse.
Connecting the speaker and the multimeter is not a headache as you have to understand how the terminals are placed and apply basic rules of (positive-negative and negative-positive).
2. Impedance of the speaker
After getting the results, the resistance of the speaker is available. But the speaker’s impedance is mostly typed on the back of the speaker measured in ohms. Use the following methods to achieve your goal:
a. So the first step you should check is to ensure the impedance in your speaker guarantees high quality. This is because using a low impedance speaker without the help of the amp can cause damage to the system.
Be warned that performing tasks with mismatched speakers and amp results in side effects when the amp or receiver is not ready to perform that task.
Remember, the speaker’s impedance varies in frequencies due to the high and low pitch you experience. Sometimes the impedance we get at the back of the speaker is just a general range.
b. Before buying a 4 ohm speaker, ensure the system can handle it. What I mean by the system is the amplifier and the receiver. When your computer publishes power ratings of both 8 and 4 ohms, you are safe.
This helps your computer operate with the speaker, successfully rating your connection to a good percentage. The volume produced is high pitch, which is heard clearly, and the message is received clearly.
c. In other cases, you can get an amp having a switch at the back of it to help control ohm settings. But the great issue comes because impedance is not a flat range. It’s a curve creating difficulties.
d. It is always advisable to keep your impedance setting at a high rate and purchase a computer compatible with the impedance setting available for better performance of your system.
Computers are designed to work with a low-impedance speaker to enable sound and volume production to be of high quality.
e. After following the procedures on how the impedance, voltages, and resistance inter-relate, you can achieve a good computer–speaker connection and the sound produced can be of high quality. You need to follow the steps carefully and know the measurements relate.
Frequently asked questions;
- When the speaker doubles the 4 ohm power rate connected to a computer, what happens?
A computer produces a voltage of 12 volts which is best suitable to run 4 ohms as it can utilize every power from the fixed voltage. It is not recommended to run your computer or speaker beyond its range limits.
Summary
Just the way I have briefly explained the two methods in detail on how a 4 ohm speaker can be used on a computer and work perfectly as it is expected. The techniques are very simple so long as you can afford the gadgets you can operate now with much ease.
In conclusion, you have realized that the specifications given at the back of the speakers are not basically exact, so you can personally conduct your measurements as long as you have the exact tools. When you find it is too difficult for you, try and conduct a professional to help you.
