Buyers’ Guide

There are many features that directly contribute to the performance and durability of CB speakers. Some of these are stated below that you should look out for. 

  • Audio Quality

When it comes to a speaker for CB radio, the sound quality is a crucial part. Most of the time there is a lot of static noise inside the output. We suggest buying external speakers that can minimize the noise and produce crystal clear audio for your listening experience.

  • Mounting Options

Many of the options available on the market come with their own adjustable mounting bracket and hardware. We recommend purchasing a speaker that has a smooth yet durable mounting bracket. It will enable you to orient your CB speaker in any direction so you can get the best audio quality.

  • Compatibility

Given the number of CB radios available on the market, each of them has its own compatible ports and options. It is good practice to buy a CB speaker that can be plugged in with multiple CB radios. This way you can use your CB external speakers with different brands rather than buying a specific one that only works with a single radio.

Frequently Asked Questions (FAQs)

What sort of plug is preferred in CB speakers?

A universal 3.5mm mini-plug is the best suitable option for CB speakers. They are compatible with most of the CB radios available on the market. Additionally, they are quite easy to replace and repair in case of wire tear or any sort of signal distortion.

What sort of power input do I need?

In most cases, an external CB speaker doesn’t need a power source. You can just plug them in with your CB radio and it will run smoothly. However, an external CB speaker with a higher power rating might need an external DC source if you want the optimal output from it.

Buying a high-performing and durable CB speaker can enhance your overall listening experience.  After using and testing multiple CB speakers, we have determined that the best external CB speaker is the Cobra HG S500 HighGear speaker.
