Types of Car Subwoofers
Hi, Guys, this is me, Ashely Roode, again, and today I have come with another article based on the information regarding the usage of speakers and to maintain their high level of audio in cars. The guys who previously read me know who I am, but for the new readers I’m just a guy, having 20 years’ experience in dealing with cars and personally owning three showrooms in New York, Kansas, and Los Angeles.
In previous article we talked briefly about the methods to increase the audio levels in your car without using or installing any amplifier, and how to keep it simple and cheap by using general methods and techniques like dampening your car floor, engine, or by using subwoofers, keeping cable connections fresh, use of capacitors, the control over electrical impedance, the music quality and use of various add-ons to keep your car buzzing in a complete hustle freeway.
I have received so much response after that article and the questions and points of that response urged me to write another article to further explain the techniques and methods regarding this topic. People have asked me various points but the most commonly asked questions were about Subwoofers.
What are they, why we should use them, how to install them properly and how to manage them on the whole? So, in today’s article, we will discuss every single information about subwoofers completely and I am very hopeful that it will answer all questions and curiosity about them.
What are Subwoofers?
Subwoofers are basically the speakers built around the LFE technology. LFE stands for Low-Frequency Effects) which means that subwoofers are the components that reproduce the lowest audible frequencies.
They are basically speakers but produce quality much more than a normal speaker. It is like a complete product, a pack of woofer and amplifier together. It has a frequency range of around 20 to 200 Hz. It enhances all audio channels and resulting in the greater audio experience.
The main difference between speakers and subwoofers is the pattern of their frequency ranges. Speakers have a limitation of producing only high frequencies and unable to produce a base effect, while subwoofer works around the lower part of audio frequencies and perfectly creates base spectrum as per required by the user.
If we talk about the structure of Subwoofer, it consists of one, two or more woofers, alongside an amplifier, placed in a wooden case so it can resist and withstand the air pressure and resistance to provide perfect base and sound. As I mentioned above already that it has a built-in amplifier so, all that you need to do is to plug it to the socket.
Talking about its parts, the primary section of a subwoofer is the cabinet, containing an amplifier. Sizes are customizable as per customer requirement and also some default presets are available (from 8 inches to 21 inches)
The voice coil contains a found magnet usually to produce sound. It also has the support of suspensions to keep control of it while getting movement on playing sound waves. Generally, there are two basic types of coils:
- the single voice coil
- the dual voice coil
And alongside this, these coils are integrated with a specific impedance. Impedance is the resistance of audio signals while transforming into audio. And they play a major role in lining and wiring up your subwoofer to achieve perfect results.
Classification of Subwoofers:
Generally, the subwoofers are classified into two following types:
This is the type of subwoofer which doesn’t have a built-in amplifier, and quite similar to general speakers. They need an external audio receiver or amplifier. The ability to produce bass is dependent on an amplifier or receiver in this type of subwoofer.
The most popular and common type of subwoofers is powered ones, as they possess integrated amplifier and subwoofer speaker, inside a wooden box, making it an all in one perfect product. Usually, subwoofers used in cars are powered types. I am using Rockville powered under seat subwoofer and that is just awesome.
There is another type of powered subwoofers, containing a wireless connection option (getting very popular these days), and making connectivity easier than wired connections. Also, you can purchase a separate wireless transmitter if your powered subwoofer doesn’t have it be built and can accommodate your cause.
Which one is better?
Well, it depends on the requirement of the user but in my personal opinion, powered one has a clear and definite edge over the passive ones. But still, it is very dependent on the requirements and needs of the user. But, the problem with passive ones that buying a separate amplifier means an increase in the cost of the product and it will really get very expensive for you.
Meanwhile, the powered ones are all in one product, takes lesser space than passive ones and one single unit it enough to provide quality results. Even by connectivity requirements, powered ones have greater compatibility as compared to passive ones.
As we know, currently we are talking about Subwoofers, which can be used in cars.
Following are the types of car subwoofers:
Self-Amplified Bass Solutions:
This type of subwoofer is a good and easy system that not only provides the user with a great experience in terms of audio output but also help users to save the maximum amount of space in the car. It doesn’t provide much powerful sound as compared to other types of car subwoofers but still in terms of saving space in a car, it is the main deal.
These are the powerful types of subwoofers, providing the maximum quality of sound. These may take some space in your car but the output is just amazing. So, for the person who can afford the sacrifice of space, it is an ideal fit.
Standard Subwoofer Speakers:
These are more like customized and user instructed speakers. They are hybrid of both bass tubes and self-amplified solutions and can provide both high-quality powerful sound and space-saving structure.
Underseat vs Trunk Subwoofers:
Now, it is totally up to you, I personally use a trunk subwoofer which is 15 inches in size. If you have a family car, you should buy a decent sized subwoofer for your car. I have just posted an article about the differences between Trunk and underseat subwoofers.
