Learn About Car Audio Subwoofers

Subwoofer to reproduce low-AKA, the lowest frequencies of the spectrum. They are essential for the SQ and SPL systems, but for different reasons. Let's take a look ...

For SQ systems: efficient to reproduce the lowest frequencies to the sound of music is full and strong. The instruments play, the low frequencies, such as organs, percussion and synthesizer sounds more realistic and powerful with a subwoofer installed.

For SPL systems: Because subwoofers are strong, are the preferred speaker to make a whole lotta noise.
Also, because our ears are less sensitive to low frequencies, we need the extra bass system for a balanced sound.

So what am I supposed to find for a large woofer from? I'll tell you!

Resilience:
As with any other part of a hi-fi system, for subwoofer and stamina is important.Earlier in my article about speakers, I was about how to send more power to increase its volume to speak, but to reduce the distortion. The same goes for the subwoofer, but be careful! Since the low-frequency distortion is harder to see, a little "to exaggerate and blow the subwoofer. In any case, that it was wise to a processor take exactly what your captions are intended to do to place but it's easy to buy?

Dimensions:
Subwoofers come in many sizes, but most often are 8 ", 10", 12 "and 15". This was taken probably in the metric-known European brands. As you can imagine, the greatest bass player, plays hard and low. Of course, the smallest musical, precise, and the sound "tight". What is the size that you choose should be a rule with their own preferences, and ideas to do the installation. Remember! 18 "subwoofer not only place it everywhere!

Reel Info:

SVC: Single Voice Coil
This means that the speaker is only one coil. In other words, only a rumor.

DVC: Dual Voice Coil
This means that the coils of loudspeakers two voices or two votes.

Why is it important?
I could go into detail, but I know I really play no role. It 'basically this: With a DVC subwoofer, there are more installation options. Look at it this way, a DVC "looks" like two subwoofers to your amplifier. With some clever tricks wires (called series and parallel connection), you can connect a wide receiver to a subwoofer - even if the amplifier is a "mono" or two-channel amplifier. You can also push the amount of ohms, the output stage. If you have an amp that has stabilized at half ohm (Orion HCCA amps like an old school), you could connect woofer 8.4 on a single channel! Imagine the noise could, you do that!

A few words about the fields:
The boxes are for the most part, the subwoofer is available. In other words, a box subwoofer as important as the same subwoofer. Why? As most will need a subwoofer box works correctly, then play well and not hurt. Subwoofer does not have a field to an "open air" or "baffle" subwoofers to be without end.

Like I said, most subwoofers need a box. So we're talking about boxing!

First and foremost, what are the types of boxes are there?

Signed and Sealed: The simplest way is essentially a suitcase, a box inside and outside are not related. There are no holes and is ensured to make sure that the box is sealed.

Carried: A subwoofer is a field with at least one hole, or "gate" in it. The purpose of the box is lifted in order to emphasize a certain frequency. These fields are used because they are often stronger than sealed boxes.

Bandpass: A field width of Banda is similar to a bass-reflex, because he, the doors, but the box banda by attempts to de-emphasize certain frequencies, while others must point out. In other words, it acts as a bandpass filter. The box shows a frequency band of bandwidth, while concentrating on frequencies below and above the carpet.

Isobarik: These boxes are for more than one subwoofer in a small box. The subwoofers are designed to work in tandem. Sometimes the two U-boat in the same direction at the same time approach that sometimes a submarine, while the other pulls. There are advantages to this type of configuration, but the box design is difficult.

OK, now you know everything about subwoofer, but here are the specifications that you need to know to select the subwoofer:

Resilience: Subs are pregnant, and the power for himself, but just as much (or distortion) before jumping into the air! The capacity is measured in watts, and is often expressed as a two characteristics: RMS and Max (or peak). The RMS rating is the most important. If a sub says it can respond up to 200 watts RMS and 400 watts maximum, when the power amplifier 200 watts RMS, as well as to offer.Not 400 watts RMS. The subroutine can handle 400 watts, can not cope with this type of energy for a short period. If you are transferring to an amplifier 400 watts RMS is blocked, these speakers are broken fairly quickly - as always at 400 watts, are not exposed to short bursts of 400 watts. You dig? Gut.

Sensitivity: This term means exactly what you think it means. In short, a subwoofer with a higher sensitivity to be louder than a subwoofer with a sensitivity if they are connected to the same amp. The specification is measured in dB.

Frequency Response: You seem to want a subwoofer can be treated as a broad range of frequencies. But most of the work of the subwoofer below 100 Hz when the subwoofer is all the way down to 20Hz, you know you have a big boat. The good news is that even if it does not go as deep, making the best music for them. So, you always will be. I guess that's more important, a submarine systems with low plays in a DVD player and 5.1 sound. Also varies depending on the frequency response of the box that the subwoofer is installed in. So in the sense that you simply choose a subwoofer, the sound and power as you want.

Cone Material: When it comes to subwoofers, this is really something very important to pay attention to. Because subwoofers are big and powerful, you need a cone material that much can withstand much abuse. I personally am a big fan of red metals such as lead. This is because aluminum is light and stiff, and also produces the resonance of the bass very tight and musical. I know that many manufacturers use exotic materials subwoofer with their sound, making it difficult to determine which material is best.

Surround material: Here's my advice: always a sub-woofer with rubber surround. Rubber lips of the best in the automotive industry.
Impedance: measured in ohms, shows the specification of how much resistance the speaker presents to the amplifier. Too much and you do not get the volume, too little, and fry your subwoofer amp! This specification will help you decide which amplifier to the subwoofer, regardless of whether you connect to your amplifier, and if the child is more U-boats in series or in parallel. Subwoofer sometimes more than one coil (aka DVC). This means that the subwoofer with two inputs have the same impedance. Subwoofer with two coils are to install more versatile, especially in multiple woofer systems.

Basic Installation of subwoofer is quite simple. If you buy a pre-fab sub box, mount the sub and the power that you have a good bass. To install professionally, and get the best sound, the planning and the work must go into the entire process. This is a situation where if you do not feel in your ability to safely build a box and set it down, you should visit a car audio shop and they do it for you. This can be very cheap or very expensive.

If you do this to solve the purpose, but not on the field to develop the skills that you can use a box of pre-fab buy. I would also recommend strongly an EQ device to fine-tune the bass. This will help to overcome the noise from the road (still low) "roar", and even risk, and "gray area". At the end of this road is the best compromise between a custom box and a box of pre-fab. You can make a great sound, and save money!

Now go easy on the ears!
