 CB Radio External Speaker Buying Guide

Buying a loud CB radio PA speaker is not that smooth. All the external CB speakers out there might not amplify the sound. Even there are some products which fail in delivering clear sound output.

This buying guide will help you to choose a CB external speaker your own.

Let us see them one by one:

1. Understand Why You need an External CB Speaker

The first thing you should focus on is the purpose of having an extension speaker for your CB device. But most of the customers fail in doing this and end up with the wrong product.

I have heard a  lot of customers complaining about the quality of the sound output- for some, the volume is too much, for others it is too low.

The basic thing is that they didn’t choose the product based on its design. These devices are designed to give a particular level of output.

Basically, there are two types of external speakers for CB radio.

1. CB PA Speakers
2. CB Extension speakers

The former one is what you need if you want an amplified sound output. If you have read our reviews closely, you now know which are the loud PA speakers for CB radio.

The second type is communication speakers. They won’t give you an amplified sound. But they are more than enough to give you clear and crisp sound in a noisy environment.

2. Assess the Mounting Aspect

Before purchasing the speaker, you need to find out how you are going to mount it.

Remember, all the vehicles are not made equal. Some vehicles might have enough space and locations for mounting an external CB radio speaker and some might not have many options.

That’s why you need to choose the speaker in such a way that it is very easy to mount to your vehicle.

One way to achieve this is by choosing a compact CB radio speaker. Most of the small sized ones are easily mountable anywhere. You can even keep some of the smallest speakers in your cupholders.

Another thing to focus is to get swiveling brackets for mounting. If your supplier doesn’t offer it, get a compatible one from local stores.

However, if you buy one of those best external CB speakers listed above, you will get all the arrangments for mounting along with the product.

3.  What are the Features You need?

Most of the CB external speakers come with nice array of features. But you might not need all these features.

Here are some of the common features you should look for in a PA CB speaker.

4. Ideal Power Rating

As you have already seen in the review part, external CB speakers are available in different power ratings like 5 Watt, 10 Watt, 15 Watt, etc.

How much power rating do you require for hearing properly through an external speaker?

We don’t recommend you to go for anything more than 8 Watt. Why?

Most people use these external speakers to hear properly, not loudly. For this, 8 Watts power is more than enough.

If you are looking for an amplified PA speaker for CB radio, you can consider higher power ratings. In this scenario, buying a CB amplifier will also do the job.

5. Design

Throughout these years no major overhaul has happened in the designing of CB PA speaker.

Most of these speakers are available in small sizes with cords and an earpiece jack.

However, brands like Cobra and Uniden has come up with a rugged design concept. With this, you can easily use your external CB speaker for more than 3 years.

What these brands do is to have a metallic grill construction for the speaker.

If you’re someone who uses CB radio on a continuous basis, having a rugged construction is a must.
