1 ohm vs 4 ohm

But what does it actually mean? Why is it important and why do we have 2 ohm and 4 ohm subwoofers? Regarding pricing, brand will always be a factor but usually 2 ohm costs a little bit more. When talking about ohm international system of unit of electrical resistance in regard to subwoofers, it mainly involves how much power it can accumulate and transform into sound.

Generally with lower electrical resistance, in this case the 2 ohm subwoofersit will produce a louder sound. Although it might be louder than subwoofers with higher resistances, it may however produce a lower quality of sound due to the power consumption.

With 4 ohm Subwoofers, they would have a higher electrical resistance and would then produce a less loud sound in comparison to the 2 ohm subwoofers.

Also, since power consumption is less, it could also mean that it will last longer compared to subwoofers with lower impedance. Having the said electrical resistance, it will also produce a more compact sound that may mean a better quality sound.

1 ohm vs 4 ohm

To explain further, let us say you have two subwoofers, one being a 2 ohm and the other a 4 ohm. With your 2 ohm subwoofer at 2.

With a difference of 2. Now for the sensitivity, i. Now at. So to put it simply, the difference is not that great if say you are planning on having a few subwoofers. It will mostly produce the same sound if they are run at the same wattage and will make little difference to the sound produced, the main difference being maybe the price.

1 ohm vs 4 ohm

If you're familiar with the online communities you're probably hearing a lot about sub ohm vaping, twisted coils, direct lung hits and massive clouds but for a beginner these terms might be confusing and could give you the wrong impression about the general aspects of vaping.

Every week I answer to several email and dozens of chat requests where people ask me what ohms should they choose, if sub ohm vaping is better than regular vaping and why is the vapor coming off their newly bought mod so hot.

For this reason I decided to take some time and write this article about vaping ohms explained, so that any e-smoker, regardless of his or her experience with e-cigarettes could understand the differences between coils.

First of all, ohms represent a unit of measurement for resistance, and when it comes to vaping they translate to how difficult is for the electrical current from the battery to pass through the heating coil.

The lower the resistance, the faster a coil heats up to a certain temperature and controlling this value is key in delivering a satisfying experience. Back when electronic cigarettes were first introduced on the market there was no such thing as sub ohm vaping. Many of the initial atomizers and cartomizers had resistances between 2 — 3 ohms and they were designed to replicate the feeling of tobacco cigarettes to the last detail.

These devices were called cig-a-likes and they were able to produce a decent amount of vapor from those resistances. However, because they weren't powerful enough and couldn't deliver a consistent amount of nicotine despite some flavor cartridges topping a maximum of 3. There's a direct link between resistance and the amount of vapor a device can produce, and it's usually the lower the ohms the bigger the clouds. This simple rule slowly transformed into a hobby for vaping enthusiasts a couple of years ago, and they started developing vaping mods and atomizers in an effort to push the limits of their devices for the biggest clouds ever puffed.

People noticed that by lowering the resistance the amount of vapor was getting bigger and bigger, however the only limit was the continuous discharge rate of batteries.

1 ohm vs 4 ohm

But, what started out more as a hobby, quickly developed into a separate niche with numerous small companies starting to manufacture mechanical mods and rebuildable atomizers to appeal to those vapers who wanted a lot more than a standard cig-a-like or your standard Ego style Vaporizer pen. Nobody knew back then that this small part of the industry would surpass the traditional electronic cigarette in only a few years and this is why nowadays we have so many mods and rebuildable atomizers instead of cig-a-likes and other 'cigarette' shaped devices.

But this transition of the industry had a positive effect on the millions of people who are using e-cigarettes today and this is mainly due to the wider choice of devices suited for each style of vaping.

And speaking about the different styles of vaping, we have two main categories of e-smokers — the ones who prefer mouth to lung hits and the ones who prefer lung hits. Mouth to lung vaping is just like puffing on an actual cigarette, with the vapor going first into the user's mouth and then lungs; while direct lung vaping means inhaling the vapor straight into the lungs.

People who prefer mouth to lung vaping are usually the ones who use standard resistances above the 1 Ohm limit and those who prefer direct lung inhale use sub-ohm resistances below the 1 Ohm limit.

If you are still a smoker, want to make the transition from smoking or are a vaping beginner, then probably mouth to lung is the best option for you, as it comes as a reflex from puffing on combustible cigarettes. Inhaling vapor straight into your lungs is something that you can't do with a tobacco cigarette and this style of vaping might seem a big weird and uncomfortable at first.

The reason for which above ohm resistances remain popular with mouth to lung vaping is due to the restrictive draw these devices can offer and the similarities with actual cigarettes. There are still people out there who prefer vaping on above ohm resistances, and their number is probably greater than that of e-smokers using sub ohm devices.

While the amount of vapor produced is not as massive as with a sub ohm resistance, some people are more than satisfied with the whole experience and wouldn't trade it for something else. The vapor is cooler, smoother and the draw is tighter, however the battery can last a lot longer and the amount of e-liquid used is way less than with a sub ohm device.

Of course the vapor tends to get warmer and warmer as you go from 2. So, if you are a smoker trying to make the switch or a vaping beginner then a device with 1. Not as a general rule, but numerous vapers start out with above ohm coils and slowly make the transition to sub ohming because they like warmer vapor or bigger clouds. And given the fact that many of today's products are highly customizable, to go from standard ohm coils to sub ohm coils could just mean purchasing a new clearomizer or changing to a different type of atomizer heads.

If you want to give vaping a try and want an experience that's relatively close to smoking then you have two options — buy a starter kit that comes with everything you need inside the box or buy a mod and atomizer separately. The second option gives you more versatility and it's very easy to upgrade to a different vaping style afterwards. On some of these devices you can also experiment with sub ohm coils, which are either included in the box as spares or can be bought separately.

The tanks or clearomizers also come with adjustable airflow and the user can easily switch between a tight draw for mouth to lung hits and an airy draw, perfect for direct lung inhale.Impedance is like great rock 'n' roll. Understanding everything about it is complicated, but you don't need to understand everything to "get" it.

Think of the speaker as a pipe. The audio signal — your music — acts as the water flowing through the pipe. The bigger the pipe, the more easily water can flow through it. A speaker with a lower impedance is like a bigger pipe in that it lets more electrical signal through and allows it to flow more easily. As a result, you see amplifiers that are rated to deliver watts at 8 ohms impedance or or watts at 4 ohms impedance.

The lower the impedance, the more easily electricity the signal or music flows through the speaker. A lot of amplifiers aren't designed to work with 4-ohm speakers.

Using the pipe analogy, you can put a bigger pipe in, but it'll only carry more water audio if you have a pump amplifier powerful enough to provide the extra flow of water.

Using lower-ohm speakers without equipment that can support them may cause you to turn the amplifier all the way up, which can damage the equipment.

Using mismatched speakers and amplifiers can cause problems when the receiver or amplifier is not up to the task. Take almost any modern speaker and connect it to any modern amplifierand you'll have more than enough volume for your living room.

So, what's the advantage of a 4-ohm speaker versus a 6-ohm or 8-ohm speaker? Not a lot — just that low impedance sometimes indicates the amount of fine-tuning the engineers did when they designed the speaker. The impedance of a speaker changes as the sound goes up and down in pitch or frequency. For example, at 41 hertz the lowest note on a standard bass guitarthe impedance of a speaker might be 10 ohms. At 2, hertz the upper range of a violinthe impedance might be just 3 ohms. The impedance specification seen on a speaker is just a rough average.

Some of the more exacting speaker engineers like to even out the impedance of speakers for consistent sound throughout the whole audio range. Just as someone might sand a piece of wood to remove the high ridges of grain, a speaker engineer might use electrical circuitry to flatten the areas of high impedance. This extra attention is why 4-ohm speakers are common in high-end audio but rare in mass-market audio. Before you buy a 4-ohm speaker, make sure the amplifier or receiver can handle it. It may not be clear, but if the amplifier or receiver manufacturer publishes power ratings in both 8 and 4 ohms, you're safe.

A relatively inexpensive receiver might not be the best match for 4-ohm speakers. It might function OK at low volume, but crank it up, and the amplifier might not have the power to feed the speaker. The receiver may shut itself off temporarily, or you may burn up the receiver. Some amplifiers and receivers feature an impedance switch on the back that you can use to switch between ohm settings. The problem with using this switch is that impedance is not a flat setting, it is a curve that varies.

Using an impedance switch to "match" your equipment to your speakers intentionally cripples the full capabilities of your amplifier or receiver. Leave the impedance on its highest setting and buy speakers that match your equipment's impedance settings for the best performance.

In car audio, 4-ohm speakers are the norm. That's because car audio systems run on 12 volts DC instead of a volts AC. A 4-ohm impedance allows car audio speakers to pull more power from a low-voltage car audio amp. Car audio amps are designed for use with low-impedance speakers.

Anyways my question: WHat is the difference between running 4 ohms vs 1 ohm. Lastly, how to you hook up the wires to run at 4 ohms vs 1 ohm, if you sub has two pairs of voice coils???

When running different impedances, the main thing is that you match the speaker to the amp that you're running to it. Lots of information for you at www. When running a dual voice coil DVC speaker, having the extra coil just gives you more wiring options more amp choices possible.

Lets say you have a brand x sub with dual 2 ohm voice coils. Now, these voice coils can be wired in series to present a single 4 ohm load. These voice coils can also be wired in parallel to present a single 1 ohm load.

Now lets say you have a brand z amp that puts out w at 4 ohm, w at 2 ohm, and w at 1 ohm. Now lets say you have a brand y amp that puts out w at 4 ohm and w at 2 ohm, but its not 1 ohm stable which many amps arent. You will then have to wire your sub in series to present a 4 ohm load, which your amp can handle. You wont be getting the full potential from your amp, but if its only 2 ohm stable, you should get a dual 4 ohm sub so that you can wire it in parallel and get a single 2 ohm load.

I hope this helpsBefore making a distinction between 2 ohm, 4 ohm, and 1 ohm, it is crucial to first understand what exactly is an ohm and how it applies to car stereo receivers. In the simplest of terms, an ohm is the amount of resistance that an object or an instrument offers to the flow of electricity. So, a resistor will feature a certain amount of resistance, which can be measured in Ohms. A speaker is essentially a resistor.

Therefore, when a speaker is given a specific ohm rating, then it refers to the resistance offered by the device to the flow of electricity through it. All the speakers come with certain ohm specifications, which look something like W at 8 Ohms.

The rule to remember is that the watts add up and the Ohms go down. It will become clearer in a minute.


When one of these speakers is connected to an amplifier, it will be called as running W at 8 ohm load. Plug in the next speaker now, then it will become a W 4 ohm load.

The power source is pushing the W metric, but the resistance is being pushed back by 2 ohms. At this stage, it really depends on the specifications of the speaker, whether or not it will be able to take the load, s it is important to do the right matching of resistance or impedance in order to keep the equipment safe. As the impedance increases, the more the resistance increases from 1 ohm to 2 ohms to 4 ohms. Another important point to note here is that as the resistance increases, it inhibits the flow of the electricity more strongly.

It literally safeguards the circuitry in the speakers. In other words, when exposed to the same amount of power, a 1 ohm speaker may blow out easily, while a 4 ohm speaker can take the load effortlessly. Consequently, 1 ohm speakers can be used for only light use. The speakers with higher ohms can also be run for longer than those at the lower end of the spectrum. If you are connecting the speakers in series, then their impedance gets added and if they are connected in parallel, it is halved.

The most important thing while hooking up a speaker to an amplifier is to know the upper limits of the resistance, below which the amplifier remains stable. If the speaker of the right impedance is not connected to the amplifier, it may burn it out.

Hooking up the right amplifier to the right speaker is very important. The speakers ohm specs help you do this. How Do They Differ?

While that might sound odd to the experienced vapor many people simply aren't explained what the ohm on their coil means and how it can effect your vape mod. So what exactly is a coil?

The coil or wick as they use to be called and still sometimes are is basically what is heated up by the battery. The actual coil itself is just small wire wrapped around a wick. That wire is heated up which in turn heats up the wick and the ejuice absorbed by the wick. That eliquid is turned into vapor which after travelling through the tank is what you inhale when you vape. There typically two types of coils, single coil and double coil.

The single coil is basically what was described above, a double coil is simply two coils and two wicks. Almost all new tanks and really any tank made within the last 2 or so years are bottom coils meaning the coil is at the bottom of the tank. You may also start to see the acronym BVC which stands for bottom vertical coil meaning that the coil is built vertically instead of horizontally.


BVC was made very common from Aspire first with the Nautilus tank and then with their regular tanks. For the most part whether using a single, dual, or BVC coil will depend on what the tank requires. Kanger protank 1 and 2 are single coil, Protank 3 and aerotanks are dual coils. Which is better? There really is no better or worse as it really depends on what you like and what gives you the best flavor and vape. Generaly speaking the Aspire Nautilus and Nautilus Mini with their BVC coils are considered some of the best vaping and flavor tanks out, ubt it's god to try a couple different options to see what you like if you can.

Where do you find the ohm of your coil?Subwoofers play a huge role in a car audio system. This is because subwoofers are specially designed to reproduce low frequencies in a sound signal.

Low-frequency sound is what is commonly known as bass. While a subwoofers is a must-have sound equipment for a bass enthusiast, most people get confused about terms such as wattage, impedance, and resistance. Resistance, to be specific, is a term hardly known by most people. Basically, resistance is a measure of the opposition to the flow of electric current by an electric circuit. Resistance is denoted in ohms. Subwoofers are usually fed with an audio signal in the form of an electric current from a head unit or amplifier.

They have a certain level of resistance to an audio signal. Most subwoofers available today have a resistance rating of either 2 ohms or 4 ohms.

Although your stereo or amp may work just okay with either a 2 or 4 ohm sub, it would help to know which would work best for the best bass quality. When buying a subwoofer and notice a subwoofer rated as 2 ohm, it means that its resistance is level as at 2 ohms.

As such, an amplifier is able to feed it with more power without much resistance. Since the resistance is low, it means that the sub will be louder. However, it consumes more power due to its minimal resistance, and this leads to lower quality in bass. A subwoofer with a resistance rating of 4 ohms means that it has higher resistance.

As such, it reproduces less sound due to its high resistance. However, its high resistance means that it consumes less power from an amplifier. You can wire subwoofers either in series or parallel.

On the other hand, if you wire subwoofers in parallel, the total resistance is the resistance of one subwoofer divided by the total number of subwoofers. This means that wiring subwoofers in parallel lowers the total resistance. While most subwoofers have a single voice coil, others come with dual voice coils.

You can have a sub with a dual voice coil where each voice coil has a resistance of 2 ohms or 4 ohms. Now that you know the key differences between 2 ohm and 4 ohm subs, including how wiring multiple subwoofers affect the total resistance, it can be easier to tell which option is better. Basically, either option is good. If you want bass at a moderate volume and in the best quality, then a 4 ohm subwoofer will be your best bet.

On the other hand, if you want the loudest bass, then consider a 2-ohm amplifier and if you have multiple subs, then connect them in series for less resistance and thus more loudness. Getting the kind of bass you want in your car is not a matter of hooking up just any subwoofer you come across in the market.
