Are higher ohm speakers better? That is the question that almost everyone who has an amplifier long enough to justify buying a new set asks.
They may wonder if the EXTRA wattage they are getting from their speakers will make a difference in the kind of sound they are hearing. But will it really make that much of a difference in the quality of the sound that they are listening to?
So, are higher ohm speakers better? No, higher ohm speakers are not better and do not produce better sounds. In general, ohms are the impedance rating for all speaker, which shows how difficult the speaker can power. A lower impedance is very efficient and can allow music or crisp sound to pass through the speaker.
In order to provide a more detailed answer, we have to take a look at what happens when two speakers are compared side by side, one with their high and one with their low wattage ratings.
The results are predictable. When you place the speakers next to each other, they will produce very similar results. In fact, their audio quality will be very close to each other.
Understanding the Mid-range of Speakers
The only difference that can be heard between the speakers in question is in the mid-range. In essence, the midrange sound is being pushed down into a sub-woofer zone.
This is not a big deal, since it will not change the overall quality of the audio that you are listening to. And this is where the difference between the two speakers can become a problem. If you are a lover of bass, you will want to get a set that has a lot of power behind it.
If you want to do some comparison shopping, the easiest place to start is with your local audio equipment store.
They will probably have all the speaker models that you need in the back. You can also check out other stores like Best Buy or Circuit City, or even Lowe’s or Home Depot for good prices.
Keep in mind that you will probably end up spending more money on a good set of speakers if you get them from the stores that specialize in speakers. However, if you decide to shop online, the prices will usually be less than you would find at your local store.
Speakers Differ in Ohm Output
Now, let us say that you still need more information. One of the things you should keep in mind is that speakers can actually differ in ohm output. You might think that they are all the same, but each manufacturer uses a different wattage rating to measure their speakers.
If you are using a set of speakers that are rated for a hundred watts, but the person you are listening to is only using a one hundred watt set, you will notice that the sound is not as deep or as rich as you would expect. The reason for this discrepancy is that the speakers that are being measured have a lower wattage.
There are many different brands and models available on today’s market, so do your research before making any purchase and you will be assured of great sound quality.
What is Speaker impedance?
What is speaker impedance? You might have heard the term ‘speaker impedance’ in the past, but you might not exactly know what it means.
Take a look at what speaker cables and audio transformers are involved in all this.
When measuring speaker impedance, each speaker’s output is measured with respect to the power source and then compared against the signal source.
Each driver is connected to four speakers with speaker wires that carry their audio frequency range. So if there are five speakers, each driver will be assigned to an area of frequencies from 100 hertz to 1000 hertz.
To get the percentage of power that is required for each speaker from the audio signal, the value of RMS, or linear transfer rate, is calculated. Then the percentage of power needed by each speaker from the audio signal is determined.
This percentage is often referred to as slope RMS, which is useful only if you’re working with speaker cables. It is written as [RMS] where [RMS] is the total amount of power delivered to each speaker over the full length of the speaker cables. You can see why this number is referred to as slope RMS.
To make things more complicated, the speaker cables also carry an audio signal amplifier. This increases the RMS value of the speaker.
You may see that the speaker cables add up to a figure called THD, or total harmonic distortion. THD is a measure of perceived distortion, and it indicates the potential damage a speaker can do to your audio system.
A speaker that has high levels of THD will generate high levels of RF. These speakers can turn up the volume on demand when someone walks in the room.
So, if you have surround sound stereo speakers, the individual speakers could be listening at different volumes, and the output from each speaker could cancel out the output from the others. In other words, this would result in distorted audio, rather than full sound.
The speaker impedance phenomenon has a lot to do with proper setup and placement of speakers in a room.
Poorly placed or positioned speakers can introduce more speaker impediment, so placement and acoustics must be carefully considered. In addition, certain types of music may be affected by speaker impediment, so you’ll have to be aware of the genres that are most susceptible to them.
Which is better 4ohm or 8ohm speakers?
There has been a lot of confusion when it comes 4 ohm and 8 ohm speakers.
In fact, there are some advantages and disadvantages to using these two different kinds of speakers, even if you only use them for headphones. So what is the best between the two? This is something that will really depend on your needs.
There are many situations where one type will be a better choice than the other. So lets take a look at what each speaker type can do.
If you want a powerful speaker, then 4 ohms is probably the best choice for you. These are usually recommended for headphone sound or stereo sound where you need the best quality sound that money can purchase. You will find that these are typically much more expensive than their 8 ohm counterparts.
However, they have a ton of power and can create great sound quality. In addition, they are usually quite durable and very difficult to break.
8 ohm speakers can be good for bass and sound effects. They typically create a much clearer sound and don’t require as much amplification from a car stereo or a headset. These are typically not very powerful but can create good effects and tones with a music CD. However, they can be a little overpowering on lower-quality audio CDs.
If you’re into the bass, then you definitely want a good set of 6 ohm speakers. The reasoning behind this is simple; these speakers will produce the loudest sound possible with the least amount of power needed.
These are great for use with rap music, rock music, or any other kind of hard-core music that demands a lot of sound.
These are also much less expensive than their 4 ohm cousins. Some people prefer these over the 4 ohm varieties simply because they can generate a much cleaner tone. However, they tend not to be as strong as the 8 ohm siblings.
Whether you end up choosing a 4 or 8 ohm speaker largely depends on your preference. Some people will swear by the 4 ohm variety and love them while others will lean toward the 8 ohm siblings and prefer them for their sound quality. In most cases, you will get what you expect from these speakers when you purchase them.
Each has its own unique sound quality and some will sound better with one type of sound and others may sound better with another.
So what it all boils down to is personal preference.
The best way to figure out which one you like the sound of is simply to do a little research on each type and decide which one you feel works best for you. It may take some time and experimentation, but in the end you should be happy with your purchase. Both types will give you many hours of pleasurable audio playback.
Do ohms affect sound quality?
A number of different techniques are used to demonstrate the effect of ohms on sound quality.
One such technique is known as the Snell test, named after the American Silencer Company that developed and used this method to demonstrate the cancellation of many sounds, including hissing, ringing, and buzzing.
In his tests, Snell found that the increased resistance presented by the wire decreased the sound intensity slightly. It was not, however, able to cancel out all the low frequency sounds produced by traffic or other sources.
This led him to conclude that do ohms had an effect on sound quality, but they canceled others that were present. To prove this concept, he introduced what is called a zero-ohm microphone and used it to demonstrate the cancellation effect of electrical currents.
These microphones operated by passing an electrical current through a small metallic plate, eliminating all the low frequencies produced by other sources. He then played back several versions of a recorded sound effect, one that was provided by a low-frequency electric generator, another with a speaker.
The sounds produced were very similar between the two recordings.
The more sophisticated techniques that are used today to demonstrate the cancellation of low frequencies produced by other sources show that the low frequency that do ohms affect does not cancel out other low-frequencyfrequency sounds.
The reason is that the sound waves produced are much lower in frequency than those waves that cancel out.
Basically, we can say that there are times when rooms cancel out other sounds, but there are times when they don’t.
When the frequency difference between the speakers and the background is greater than the combined frequencies produced by the speakers, then there will be a cancellation.
The problem that most sound experts have is that they don’t understand the cancellation phenomenon when it comes to sound produced by electrical sources.
They think that as long as there is some amount of energy that is allowed to flow between the source and the medium (room or floor) that any sound that is produced will cancel out. However, this is not the case.
Most audio engineers (and technicians) have experienced this phenomenon and know how to correct it, but the average person doesn’t.
So do Ohms Affect Sound Quality?
Generally, ohms doesn’t affect sound quality since it’s not related to the sound system. However, ohms is concerned with the amount of energy required by an amplifier, which can be transferred from the circuit to the speaker.
But again, it depends. Why? If the audio engineer corrects the cancellation by equalizing the levels, then the effect is canceled out. If you don’t compensate for the increased levels, then the effect is nearly permanent.
If you compensate for the increased levels, then you may hear the same quality as before, but it will probably be better. If you don’t do anything, then you may hear whatever you want.
