Does the speaker matter? Here is what you need to know about the spokesman’s resistance

Om is one of the specifications that characterize both speakers receiver Manufacturers are used to give you an idea of ​​their performance. Specific amplifiers and amplifiers are usually classified about 8 ohms, but this is not always the case. If your reception device is classified in 6, for example, does this mean that you cannot connect 8 or amplifiers? For this issue, what is ohm?

Although the adoption technically does not matter, it is not completely cut and dry. She said, “The speakers with the disabilities X must be only connected to receptors with the Dagger Y. Indeed, unless some rare speakers, or really strange, can buy the vast majority with any modern reception device. I will try to explain all this as simply as possible because the technical answer to” OHM is the unit of electrical resistance “is not Especially useful for anyone in high school sciences currently.

What is ohm?

Om is the electrical resistance unit. I just joke. Well, this is, but this is what is more important to amplify the sound. The speakers have at least one, and many drivers are usually. These drivers are usually a magnet connected to moving materials. When the aforementioned materials move or vibrate against the air, they create a sound. The electric field that causes this movement is created by amplifier. How difficult the driver or drivers move is part of what constitutes the resistance of the speaker, which is classified with ohm.

The vast majority of speakers on the market are classified today in or about 8 ohms, although you can find some of the 4 ohms works. Speakers with less than 4 ohms, or higher than 8 ohms, are rare and are usually dedicated to landing.

Why doesn’t it matter (mostly)

Displacement classifications are mainly incomplete. No speaker is the same handicapped in all frequencies. If one is classified on “8 ohms”, it may be at 1K, 500Hz, 20K, or in any frequency literally. There is no organization that says it must be classified at a specific frequency. “8 ohms” says that this is what people expect. Is this average through a set of frequencies? Depending on the design of the speaker, the resistance can vary at any frequency between 2 and 8 ohms, or even its height to 40 ohms! This classification is almost always average.

This “nominal” range is also what most receptions or salad amplifiers are designed. That is why most of their power classifications are also in 8 ohms (i.e. “100 watts in 8 ohms”), but most of them will not face a problem if the speaker is less than that. If you are trying to play a 4 -ohmed amplifier from a 8 -ohid reception, then the most likely result is that it will make more hotter. You should work a little more to supply the headphone with the strength he wants.

Do you face cheap ampere problems with a loudspeaker with a really low resistance? Yes, but in general, it is very easy to drive cheap speakers that you can associate with inexpensive amps. Why is anyone associated with a difficult speaker with cheap ampere? The best condition, at least for efficiently designed products, is that if the amp is severely driven, then it will be turned off simply. This is indicated as “going to protection” and unless it is a particularly bad design, all you have to do is restart it again. The reason is that this conjugation is not a good idea due to this worst scenario: something in the series can explode and cause horrific damage-whether it is for amp, loudspeakers or worse than your hearing. The general rule of CNET is to spend the same on a loudspeaker as it does on a pair of sibros.

It should be noted that many companies that sell speakers who have less resistance often say, “Compatible with 4, 6 or 8 ohms classified.” On the other side of the price spectrum, many Home systems in the box (Remember these?) It was very low resistance. It is designed with the specific amplifiers, which came in the box, and allowed the companies to do some creative marketing. I will also explain in the end, the amp was evaluated at 100 watts to 2 ohms is really capable of 25 watts to 8 ohms. Which looks better on the side of the square?

Exceptions

With the vast majority of speakers, all receptions and amps will work. Of course, it will! Manufacturers generally want the widest possible audience, so they will not design a product that will not work with a large part of it.

There are some speakers on the market, however, you simply need great amplification. Usually, loudspeakers have a low resistance that requires a lot of amps. The power source, which is a vital component in any amplifier, must provide enough power to the hungry amplifiers. Just as no one tries to pull trailer with a bicycle speaker that is difficult to lead to a decent ampere.

This is not the type of speakers that you find in Best Buy, and if you are in this type of store that sells these high speakers, sales opportunities will also talk to you about getting ampere to go with them (as it should).

Well, now a few mathematics

If the speaker has a low resistance, this will require more current in the same effort. That is, if you do half the number of ohms, you need to double the amount of energy required. Therefore, if the 8 ohm amplifier requires 100 watts for a specific size, then the 4 ohm amplifier will require 200 watts to produce the same size (watts = amps x volts). Can amp decent do this? certainly. Can you do cheap ampere? maybe. Interestingly, many of the high -end chest manufacturers will actually be proud of this. They will evaluate their ampere, for example, “200 watts to 8 ohms and 400 watts to 4 ohms.” This shows that the ingredients are fat enough to deal with everything required by the amplifier.

Should you care? Unless it is difficult for your loudspeakers, or those you are thinking about, driving and You are trying to run them with cheap or less powerful amps and You explode them in a large size, then no. Most of the main amplifiers can be turned on all the prevailing reception devices and ampere. All are designed to do this exactly.
