Everything You Need To Know About 4 Inch Speakers

Speakers largely determine the kind of sound experience you’ll get in your car. Although you might have a top-quality head unit, you won’t enjoy high-quality sound when using factory speakers.

Among the most popular replacement speakers are 4 inch speakers. Read on for everything you need to know about 4 inch car speakers.

Types of 4 Inch Speakers

Four inch car speakers are available as either component speakers or coaxial speakers. Component speakers only feature a single driver that reproduces a single frequency range. If you want to install component replacement speakers, then you should consider investing in separate midrange speakers, woofer, and tweeters for full-range sound. 

On the other hand, coaxial speakers come with several drivers built in one speaker basket. In this case, coaxial speakers can be 2-way, 3-way, or 4-way speaker system. A 2-way speaker comes with a woofer driver and a tweeter. A 3-way speaker comes with a woofer driver, midrange driver, and a tweeter. A 4-way speaker comes with a woofer driver, midrange driver, a tweeter, and a super tweeter. The most common types of coaxial speakers are 2-way and 3-way speakers, which are generally more affordable than 4-way speakers. 

Advantages of 4 Inch Speakers

Although 4 inch car speakers are relatively small, they come with multiple advantages that make them a great choice for any car music enthusiast. For instance, these speakers are an inexpensive choice. Their small size means that fewer materials are used during the manufacturing process. Consequently, they’re generally affordable and a great choice for anyone who needs a car speaker upgrade but has a tight budget.

Another advantage is that these speakers can fit in tight spaces. If your car lacks enough space to install larger speakers, these are the right speakers for you. You can easily install them in the doors and the back dash. As a result, you’ll find it relatively easy to install them. 

Also, these speakers don’t require a lot of power to reproduce sound. Their small size and lower power ratings mean that you can easily drive them with a low-powered amplifier. Thus, you don’t need an expensive amplifier to drive them. Besides, you can easily power them directly with a high-performance head unit such that you won’t have to use a standalone an amplifier. 

Additionally, 4 inch car speakers are available as either component or coaxial speakers. You can choose component speakers for custom sound or coaxial speakers for full-range sound.

Disadvantages of 4 Inch Speakers

While these speakers come with several advantages, they also come with a few disadvantages. For instance, they don’t deliver deep bass. Their small size makes them unable to move a lot of air. Consequently, they’re unable to reproduce earth-shaking bass. Also, they’re not very loud. Thus, if you’re a bass lover, you’d want to install a separate car subwoofer or more powerful speakers. 

Applications of 4 Inch Speakers

Four inch speakers are most suitable for use as replacement speakers when upgrading car speakers. They’re a great replacement speaker for low-performance factory speakers. These speakers are also ideal for installation on the car door. You can also install them on the dash. They’re also great for installation in cars with tight spaces where larger speakers wouldn’t fit.

How to Choose 4 Inch Aftermarket Speakers

Now that you know more details about these speakers, it’s also important to know how to choose a reliable option for the best performance. Here’re the factors you should consider:

1. Build quality

For a speaker to reproduce high-quality sound, it should be made of top-quality materials. The woofer, tweeter, speaker surround, and magnet among other materials should be made of durable and high-grade materials. For instance, the woofer driver of a component or coaxial speaker should be made of a still but lightweight material to reproduce low frequencies effortlessly.

If you’re looking for a coaxial four inch speaker, ensure the tweeter material is made of a material that can reproduce the kind of highs you want. For instance, if you prefer listening to soft, smooth, and more refined highs, then consider a tweeter made of softer materials such as textiles, silk, and poly. On the other hand, if you prefer listening to bright and harsh highs, then consider a tweeter made of harder materials such as ceramic and metal.

Also, ensure the surround is made of a material that can withstand extreme temperature and humidity. Rubber surrounds are more popular today due to their longevity and flexibility, but add more to the cost of production than cloth and foam surround material.

2. Component vs coaxial

You should also consider whether you need a component or coaxial four-inch speaker. Component speakers offer more superior sound than coaxial speakers since they’re dedicated to reproduce only a single frequency range. However, component speakers are more challenging to install and are generally costlier than coaxial speakers. On the other hand, coaxial speakers, also known as full-range speakers, are great for a simple and affordable upgrade. 

3. Power handling

When choosing a four inch car speaker, you should consider its power handling. Power handling refers to the amount of power that a speaker can handle safely. Power handling is denoted in watts and is determined by RMS power and peak power. RMS power refers to the amount of power that a speaker can handle safely over a continuous period of usage. 

On the other hand, peak power refers to the amount of power that a speaker can handle in short power bursts. RMS power rating is more important as it will guide you on the kind of a head unit or amplifier to use with a specific speaker. Ensure the replacement speakers you want to buy can be powered by your car receiver or amplifier.

4. Sensitivity

The sensitivity of a speaker refers to the amount of sound that a speaker can reproduce from the power it receives from the head unit or amplifier. Speaker sensitivity is denoted in decibels (dB). Generally, if you have a low-powered head unit or amplifier, then consider a speaker with a high sensitivity rating such as over 90 dB. One the other hand, speakers with low sensitivity, typically below 90 dB, are only ideal for use with a powerful external car amplifier.  

Conclusion

While 4 inch speakers are relatively small, you shouldn’t overlook them. They’re designed to add finer music details that larger speakers may not achieve. Also, if you’re not ready to pump hundreds of dollars into a car sound system due to a tight budget, then you’d rather invest in these affordable speakers. By replacing your factory speakers with 4 inch aftermarket speakers, you’ll enjoy a better sound experience without breaking the bank.
