Buying Guide Of Best External CB Speaker
Before going on all bad and buying the most publicized CB external speaker, it is better to get some theoretical knowledge. It will allow you to never regret your choice. You must be exactly sure why and what you buy. Let’s start with “why.”
Why need external CB radio speaker?
Many people think that the CB external speaker is a marketing idea. But if you ever had a CB radio, you know that the built-in speakers sometimes work very badly.
I saw such samples that transmitted only noise and interference and anything but sound. It is for such CB radios with bad speakers that CB external speakers are needed.
In addition, external radio speakers have many interesting updates that are not available for built-in speakers.
For example, some CB external speakers have emergency channels, a reverse system, and so on. If you are a connoisseur of good sound (without interference and noise), then the CB external speaker is exactly what you need.
Features to look for during purchase
And now I am going to tell you some ultra-important features you should look for during you try to find the best external CB radio speaker. I considered these features and functions while I made the purchase a lot of the time. So I should share my knowledge about the lucky purchase.
The reasonable purpose of the purchase is what distinguishes the normal buyer from the shopaholic. The presence of the purchase purpose excludes dissatisfaction with the purchase in the future.
Surely you met people who were shopping and then disappointed. In the case of the CB external speaker, people are unhappy with loud or too low a volume and make a hasty verdict that the external speaker is a complete disappointment.
In order not to be offended by the whole world because of a hasty purchase, determine what you want from the CB external speaker. External speaker is a must have item for truckers cb radio.
For example, I chose this: high-quality sound without noise, the noise suppressor, the ability to control the volume and compactness – for this I am ready to pay my money. Define your goal: you want to get only better quality reception or CB external speaker should have something else.
The way the CB external speaker is installed is also very important. After all, you will install an external speaker in the car, and there is a limited place. In addition, you want to enjoy the sound, not another problem “how to install the speaker”, so everything should be very simple.
As most speakers are installed inside the car, the CB external speaker is designed so that are easy to install. At least, most of the speakers that you see in the store will be just that. If speaker cable is long then there is a benefit.
If you see a swivel bracket on the CB external speaker, you can be sure that installing this speaker is easy. I also noticed that the expensive CB external speaker must have all the necessary accessories for installation.
So, if you do not want to “mess around” with the installation, choose a speaker that will have a bracket (turning) and the necessary equipment for installation.
It is a very important indicator, for which most CB radio users buy CB external speaker.
Typically, small speakers have a high tone, and large speakers, by contrast, have a deep tone. The sound quality is highly dependent on power. If the speaker gives 10 watts of power, you can be sure that it will give a good, correct sound at optimum volume.
They say that “there are no friends in the taste and color,” but the design of the CB external speaker did not go far and in general it is always about the same. Manufacturers call this “modern design.” Actually, this is a small black or gray box.
The design of the CB external speaker also includes a cord of several jokes, an earpiece jack (3.5 mm as a rule) and plug, as well as a swivel bracket or some similar system for installation. And the whole “modern design” ends there.
And if you expect from the word “design” something futuristic and fashionable, forget about it. When choosing a CB external speaker, mobility is more important.
Fortunately, the manufactures of the CB external speaker are smart enough to make small external CB speakers. Perhaps all the speakers have such an important quality as portability and will not disturb you in the car with its bulkiness.
I would recommend making a choice in favor of small speakers because you can place a small speaker anywhere on the car for a cool sound.
The swivel bracket is needed for the speaker to be mobile and you can turn it. The bracket rotates at different degrees – 90 and 180. Choose only models with a swivel bracket, because there are straight lines as well.
Not all CB external speaker models have a talkback function. Although this function seems very useful to me. You can use it to control the clarity of voice, to tune in a CB radio and just to justify the price of the speaker.
You may not agree with me, but I am sure that the noise canceling function should be necessary. First, you buy the CB external speaker to get rid of the noise from the CB radio.
Secondly, the noise canceling helps to clearly hear your interlocutor. Yes, the presence of this function makes the CB external speaker a bit more expensive, but it is worth it.
Many CB radios have an Ext Speaker connector on the back. This connector is designed to connect the CB external speaker. In turn, the radio external speaker has a plug at the end of the cord. This plug is very similar to the headphone plug and has exactly the same size – 3.5 mm (or the size may be different, I took the most common size as an example).
Power is also a very important feature. Many people consider the power at first, and then other functions, and this is absolutely correct. Too much power is as bad as too little power.
Firstly, if the external speaker for CB radio has a very high power, which has no analogs anywhere, this is obviously a marketing move and the speakers will produce less power.
My experience tells me that the power of 10 watts is enough for high-quality sound at normal volume, which does not ache.
But if you want to get more power, you need to use an amplifier. The speakers will not give more power.
If you make a choice for color, it is for nothing. The fact is that the assortment of color is very narrow – these are only black and gray models. In order to find models of other colors will have to “sweat.”
When you go to the store or surf the Internet for CB external speaker you will see a lot of brands. Some of the brands are really good, but some are not. I advise you to pay attention to the following (in my opinion the best) brands:
RoadPro brand makes small compact amplifiers with low power, which will save the strength of the external speaker for a long time. The brand makes its metal products, so it is quite durable.
As for the sound, it is purely already at an average volume level. I used the products of this brand and it is easy to install in the car due to the compactness of the speaker.
Vectorcom also makes a compact CB external speaker of low power. It is sufficient for optimum clear sound. And this brand makes affordable products affordable for everyone.
The products of this brand were created specifically for those who want to get just good sound without additional features.
Midland is a good brand that makes the external speaker for CB radio with high performance. I like that this brand does not overstate the price of products, despite that it has all the necessary functions.
The brand makes powerful products (up to 15 watts) with good sound quality. Midland external speaker is a strength, strong signal, and compactness – in short, everything you need.
Cobra makes some of the most powerful speakers you have ever seen. The design of the speakers of this brand is the same as the design of other CB external speakers (only in an aluminum shell and with a metal grid) but inside everything is different.
First, the brand “pumps up” products with a capacity of up to 15 watts, as well as many additional features from noise reduction to talkback feature.
Uniden makes a slightly different design, unlike the design of other brands on the market – it has a very small size. I do not know why but the dynamics of this brand work not only with CB but also with scanners. The brand supplies the speakers with silencers and high sound quality.
The price is different – from $ 15 to infinity. As a rule, the price depends on how many functions the external speaker has. The noise canceling function, talkback function, and high power rating make the price high, but it is worth the money.

How to Install CB Radio External Speaker?
As I said, 98% of all CB external speakers have swivel brackets.
The bracket is a kind of fasteners that you can fasten to the chair or the roof and anywhere in the car. The bracket has two holes in which you should tighten the screws.
But before you tighten the screws, be sure that the length of the wire from the CB radio external speakers reaches the radio.
To connect external radio speaker to CB radio you need to follow these steps:
- First, install the speaker in the right place, which will be most convenient during using.
- Be sure that the radio output power is higher than the CB radio external speaker output power. A simple example: the power of the radio is 8 watts, and you bought a speaker whose power is 15 watts. In this case, only a miracle can help you connect the speaker to the radio, one of the two will be useless.
- Take the cord from the external speaker (this is one). The end of the cord (plug) must be inserted into the appropriate connector on the radio.
- If you want to keep the speaker for a long time, you better turn off the radio before connecting.
What the difference between CB external speaker uPA tones?
The difference is placement. For example, CB radio external speaker is installed inside the car and transmits incoming signals only inside the car.
And PA due to the fact that the public address is used on the outer part and transmits signals from you to others. Plus, using PA requires a microphone.
Where does the CB external speaker take 10 and 15 watts? Does it work on batteries?
Many people think that the external speaker requires batteries or something else to make it work. In fact, it is not. The speaker takes energy from your CB radio. We can say that CB is the power source for the external speaker.
Which body of CB external speaker is better – plastic or metal?
There are various CB external speakers on the market – some are made of plastic, and some are made of metal.
Since none of the speakers are water-repellent and generally not suitable for use outside, strength does not matter. However, I still recommend choosing metal-cased models because it provides better shielding.
In my opinion, the purchase of the best CB radio external speaker is a very good investment that will quickly pay off with a good sound. If you choose the right speaker and do everything correctly, you can get a clear connection with the world immediately.
CB radio external speaker is a unique thing that has everything you need and does not require the purchase of additional accessories. It is what makes using CB radio even more enjoyable.
