If you see a subwoofer that looks like it’s upside down, assume it’s really upside down. However, there are many arguments about this. We always get into trouble when it comes to setting or determining whether a subwoofer reverse is in the subwoofer phase. All the questions and information about the subwoofer are the topic of today’s article.
What Is A Car Subwoofer?
When the word subwoofer comes with inverting, it means it is upside down. The magnet is usually inside the box, but in the case of an inverted subwoofer, the magnet is facing the outside.
However, we are used to seeing the magnet inside the box. The subwoofer phase refers to the time it takes to send a sound signal. Sound signs travel as waves that contain pinnacles and boxes.
What If Your Subwoofer Is Phased Out?
If two sound waves travel together, their maximum and lowest waves are the same. In this way, when the high and low positions of the two waves meet, the signals come together. Strong waves are created through this constructive intervention.
The main speaker and subwoofers of the theater are connected, which means cones of the speakers and subwoofer move towards and backward to the frequency. A crossover wave is a meeting place where speaker frequency and subwoofer cuts in.
But if the signal is not at the same time at the same speed, then there is some difficulty, so that the high meeting place and the low meeting place do not come together. The more signals are out of the subwoofer phase, the more problems there will be.
That means cones of the primary speakers will displace backward and the cone of the subwoofer displaced forward. Due to which the signal will not go in from outside and will generate less powerful signals.
So it is very important to control the phase in the case of theater. The importance of phase is due to the fact that it improves the sound quality and makes the sound melodic. But the issue is, if there are any errors in the phase, it is not easy to find out.
How The Inverted Subwoofer Helps
Many say the inverted subwoofer helps keep the sound box cool and gets louder. An inverted car subwoofer is not always going to help. Many people choose the subwoofer of the car upside down.
Why most people like it –
- Gives a unique look
- It’s pretty cold because most of it is outside.
- Last longer than usual car subwoofer
- Require less space than usual car subwoofer
- Subwoofer makes the installation easy for a new box
- It is very small in size as most of it is faces outside
- High volume
Subwoofer Phase Control
Do you know how the phase works? The normal phase subwoofer operates at 0-180 degrees. The phase subwoofer eliminates the delay by connecting to the current. Since most subwoofers operate at 0-160 degrees, they combine small ranges to create the best sound.
In the case of home speakers, it helps to generate high-quality sound by eliminating signal delays. 0-160 degrees means the rate at which waves are transmitted. The higher the value in degrees, the more signals will be transmitted.
Determination Of Phase
The phase switch is used to use the correct phase. So that phase can work in harmony with the rest of the sound boxes. There is no quick way to know if your phase is out because the subwoofer phase depends on the place where you’ve put it.
To determine the subwoofer check these:
- Sound comes out at low volume when the phase cannot work at low frequency. Because the low frequency makes the outer baseless powerful and the lower base,
- The bases come out together without sounding differently.
- Examine how the bass works at high and low frequencies.
- Listen to the base by changing the position, setting the phase to the best sound.
- Use SPL method
- Use a sound pressure level meter to check the effect of phase output.
- Thin sound with no bass
- Difference between low and high-frequency sound
Would You Prefer The Reverse Phase?
There are a few reasons why you might prefer the reverse phase in the subwoofer. One reason is that it can produce deeper bass sounds. When the woofer is firing in phase, the sound waves focus on hitting one spot and don’t travel as deep down into the speaker cone.
This can cause a loss of bass quantity and quality compared to using a subwoofer with reverse polarity. Another reason to use a subwoofer with reverse polarity is if you have an amplifier that only supports phase in/phase out operation.
When using a regular subwoofer, the output signal will be out of step when it reaches the amp, but with a reverse-polarity subwoofer, this won’t happen. The most important reason to choose a subwoofer with reverse polarity is that it will offer better bass sound quality.
Subwoofer Reverse And Subwoofer Normal
We know that subwoofers work at 0-160 degrees frequency. It is a normal subwoofer when you set your phase to 0 frequencies. But when you do phase setting at 180 polarities, it is the reverse subwoofer.
Subwoofer normal: Polarity of the relative and same sub is (+/-)
Subwoofer reverse: Polarity of the relative and same sub is 180 degrees.
When one subwoofer is set to the opposite degree of another, the speaker moves outwards.
But if the signal is not at the same time at the same speed, then there is some difficulty, so that the high meeting place and the low meeting place do not come together.
Why Would You Prefer The Normal Phase?
Some people might prefer the normal phase in subwoofer reverse because it gives a more natural sound. The reversed phase can be harsh and artificial sounding. Some advantages to picking the normal phase in subwoofer reverse include: it provides a more natural sound, it’s easier to hear low frequencies, and it can produce louder bass than when the phase is reversed.
On the other hand, reversed phase can be more beneficial in some cases because it allows for a better inflow of deep bass frequencies. There are some disadvantages to preferring the normal phase when setting up a subwoofer in reverse. The main disadvantage is that it can produce harsher and more artificial-sounding bass than the reversed phase.
Additionally, it’s harder to hear low frequencies during the normal phase because other sounds in your room will silence them. Reasons behind not to prefer reverse the phase can be many.
One reason is that they may prefer the normal phase’s fuller and more natural sound over reversed phase. Some people find it easier to hear low frequencies when the subwoofer phase is normal.
Conclusion
I hope you have found the answers to all your unknown questions about subwoofer reverse by now. We want to reiterate that many people prefer an inverted subwoofer because all the speakers are inside, but the speakers are outside, so there is more space available.
This does not mean that changing the location will improve their quality. And if you want, you can check your phase in many ways, maybe even through SPL.
FAQs:
1.What Is The Best Way To Measure Your Spl?
Ans: The best way to measure your SPL depends on your specific equipment and recording conditions. However, some standard methods for measuring SPL include using a calibrated acoustic meter or sound level meter, playing back audio files at different volumes, and listening for sudden spikes in volume.
2.What Are Normal And Reverse?
Ans: Normal is when something occurs in the natural course of events. For example, sunrise and sunset are everyday occurrences.
The reverse is when a process or outcome goes against what would be expected. When athletes lose in a competition, they have lost reversely – they expected to win but didn’t.
3.What Is Phase Control?
Ans: Phase control is the ability to adjust a device’s output signal to match the input signal. This can be done manually or through automatic adjustment of parameters within a circuit, often referred to as feedback. Phase control allows accurate sound wave reproductions by comparing the input and output signals.
4.What Is The Best Way To Measure Your Spl?
Ans: People will have different preferences for how loud they want their music to be, and there is no guarantee that any one measurement technique will always provide the most accurate results.
Some standard methods to measure SPL include acoustic reflectivity measurements (such as those made with a microphone), decibel readings from audio meters, and amplitude measurements of sound waves using a spectrogram or waveform display software.
