Car audio and video Speakers: What you need to know


Speaker Advice…

Speaker systems are very significant because they are the units that reproduce the sound from power. When I buy speakers, My spouse and I only want to get high-end. Can do that for you. You need to know what to look for:

Let’s start with the types of audio systems you’ll encounter in the car audio tracks world.

Woofer: A large loudspeaker designed to reproduce the lower eq of the audio spectrum.
Middle of the: A medium-sized speaker made to reproduce the middle frequencies from the audio spectrum.
Tweeter: A little-sized speaker designed to replicate the highest frequencies of the sound spectrum.

There are other variations of those speakers available as well.

Might certainly hear of “subwoofers”, which reproduce the lowest sound frequencies. Essentially, these are the same thing as woofers, just much more significant and with more power control. The result? Thunderous bass! Much like the gods sent it their selves…

You might also encounter “midbass” operators. These are similar to woofers and tend to be usually used to bring considerably more bass to the front soundstage. Often, they are connected to crossover networks.

Another type of speaker you could encounter is called a “supertweeter” and reproduces the highest eq in the audio spectrum.

Today, to shock you…

When one buys a “speaker”, you are buying a speaker system. AKA, multiple things work together to have a result. Let’s take a look at the kinds of speaker systems available…


You will discover two types of speaker “systems” that exist.

1 . “Coaxial”, “three way”, “full-range”, etc .

This kind of speaker system is designed to go with the factory speaker location of your vehicle. They are often referred to as a new “speaker” but have more than one subwoofer and will also contain a crossover. (coaxialspeak. jpg)

2 . “Components”, “Seperates”

These speakers take everything from the above speakers and break it into parts. (component speak. jpg)


To restate benefits, one speaker system has each one of its components in one offer, and the other system features all of its components with separate packages. Both sound systems do the same thing, in addition to working in the same means, BUT COMPONENT SYSTEMS USUALLY ARE BETTER.


I’ll let you know, hoss!

But before I do, you must know about the PROPERTIES OF HIGH EQ. OK, it’s boring. Thus I’ll give you the executive synopsis: High frequencies are incredibly narrow in their dispersion. (Why, huh? ) In short, high frequencies (if we could see them) disperse being a string. Low frequencies, whenever we can see them disperse being a fan.

So, since highs don’t disperse very well, they want to be aimed at the ears. Otherwise, we won’t pick them up! This is one of the advantages connected with component systems; they encourage the tweeters to be aimed! Why do some of us want this? So when any singer hits an “s word” or cymbal failures (both of these things take place in the higher frequencies), requirements will SPARKLE, rather than damping the sound deaden it and make it flat.

An additional component: Their crossovers are usually higher quality units compared to what you’ll find in coaxial or full-range speakers systems. This is undoubtedly good because you’ll present less distortion to your loudspeakers and be sure that they are only playing the radio frequencies they’re designed to play. The results? BETTER SOUND.

The last selling point of components is that they are GENERALLY intended for people more interested in sound quality. For that reason, components are generally higher in quality. Regarding coaxials, the rest of the most expensive models will be eclipsed by the quality of factors in the same price range.

ALL RIGHT, OK. I know not all people will consider component subwoofer systems. The truth is that they are challenging to install correctly and are more pricey. Of course, if sound quality is your thing, you’ll go through the added effort! Even car companies are getting with the program today and including component speaker devices in their vehicles. Even my very own lowly Honda Civic features ’em!


So, you might have noticed me using the term “crossover” above. You might not know what a crossover is and what it does. Essentially, a crossover takes a complete spectrum audio signal, breaks it up into various frequency “bands”, and transmits the appropriate frequencies to the correct speakers. Here’s a picture!

If this explanation was too austere for you, you could examine my crossover site for more in-depth info. Thanks a lot!

OK, OK, OK. Time to get down to organization and look at speaker features and how they affect anyone.


This is often expressed throughout inches (but sometimes metric for European brands), along with referring to the phone speaker’s MOUNTING, not the actual speaker. Intended for round speakers, the size is 6. 5″ or 5. 25″. About oval speakers, the sizes are given, such as 5×7″ or even 6×9″.

Mounting Depth:

Essentially, this tells you how heavy the speaker is driving its mounting. Most audio speakers are about 3-4″ ins deep. This is important to know since you want to ensure enough room driving the speaker to attach it properly.

Frequency Reaction:

This tells you what eq the speaker is capable of reproducing. Most great speakers will go as low as 50hz and 20, 000hz (and beyond). However, if you plan to add subwoofers to your system, you don’t need your audio speakers to go much lower than 100hz. Also, your speakers don’t have to go higher than twenty 000hz since we lowly humans can’t hear anything in that frequency range.

Energy handling:

This is the amount of energy a speaker can handle without damage. This is usually expressed in two ways: RMS as well as MAX. RMS is what the actual speaker can handle continuously, plus the MAX rating tells precisely what the speaker can handle in short breaks.


This is measured throughout Ohms and tells you the amount of resistance the speaker possesses. The only valuable thing regarding this spec is so you know what ampere to hook your audio system up to. Most car audio systems (except subwoofers) are 4-ohm speakers, and all auto receivers are built to handle some ohm “load”. Most built-in amplifiers can also handle 2-ohm loads, but 2-ohm speakers are rare. Outlined on our site says this spec is more critical when it comes to subwoofers rather than speaker systems.


Scored in DB, sensitivity primarily tells you how loud some sort of speaker will be. You want a much more sensitive speaker at the rear of your speakers off of the power amplifier. When running your speakers off a higher-power amplifier, the sensitivity rating is much less essential. Also, more sensitive audio speakers tend to distort more easily.

This a fast word about power dealing with amps and distortion…

AUDIO SPEAKERS DO NOT GET DESTROYED BY VOLUME LEVEL, BUT BY DISTORTION! Therefore, your primary goal is to restrict the amount of distortion your audio speakers receive. Not only does this choose music sound better, but it also protects your speakers from premature damage.


Buying as much electrical power as you can afford, even if the idea exceeds the “power handling” spec for your speakers.


Because, because turning up the volume too high are what causes your amplifier for you to “clip”. This is the worst disfigurement that you can send to your audio system. It is caused by trying to get excessive volume out of an ampere that can’t provide the idea. SOOOO, you get a BIG, AWFUL amp with plenty of energy. Now, when you turn up the amount high, you’re simply starting to get the amp heading instead of pushing the actual amp’s limits. So, instead of clipping, the actual amp sends an excellent, thoroughly clean signal to your speakers. No distortion, no damage, NOT A PROBLEM!
