bass. bass. Loudness. glory. The most annoying component of the system is one of the most necessary components.
If you've read an article about speakers, you need to speed up. If you haven't already [and don't know anything about speakers or subwoofers], read it here.
The subwoofer reproduces the lowest frequency of the audio spectrum, the AKA bass. They are important for both SQ and SPL systems, but for different reasons. Let's take a look...
For the SQ system: effectively reproduce the lowest frequency, making the music sound full and powerful. With a subwoofer installed, playing lower frequency instruments such as pianos, drums, and synthesizers will sound more realistic and powerful.
For SPL systems: Because the subwoofers are loud, they are the preferred speaker for overall noise.
In addition, because our ears are less sensitive to lower frequencies, we need extra bass to keep the system in balance.
So what do I need to look for in order to find a great woofer? I will tell you!
Power processing:
Just like the rest of the stereo system, power handling is also important for subwoofers. Earlier, in my article on speakers, I talked about how to send more power to them to increase the volume, but to reduce distortion. The same is true for subwoofers, but be careful! Since the distortion at lower frequencies is hard to detect, it is easy to overuse and reduces the frequency of the subwoofer. In any case, with this argument, it is wise to buy an amplifier that accurately delivers the subwoofer design, but let it go!
Size:
Subwoofers come in a variety of sizes, but the most common are 8", 10", 12" and 15". For European brands, this may also be a measure. As you can imagine, the larger woofer is the woofer with louder sound and lower volume. Of course, smaller concerts are more musical, more precise, and more "compact". The size you decide is usually related to your own preferences and installation considerations. remember! 18" subwoofer is not only suitable for anywhere!
Voice coil information:
SVC: single voice circle
This means that the speaker has only one voice coil. In other words, there is only one input.
DVC: Dual voice coil
This means that the speaker has two voice coils or two inputs.
okay. Why is this related?
I can get in here, but I know you don't care. Basically, it boils down to: With DVC subwoofers, there are more installation options. Looking at it this way, the DVC "looks" like the two subwoofers of the amplifier. With some beautiful routing techniques [called series and parallel], you can connect many subwoofers to a single amplifier even if the amplifier is a "mono" or two-channel amplifier. In addition, you can control the number of ohms pushed by the amplifier. If your amplifier is stable at half ohms [like some older Orion HCCA amplifiers], you can connect 4-8 woofer to one channel! Imagine the noise you can make!
Some words about the box:
Boxes are essential for most subwoofers. In other words, consider a subwoofer's box as important as the subwoofer itself. why? Because most subwoofers need a box to operate properly, it sounds good and won't damage itself. A subwoofer that does not require a box is called a "free air" or "infinite bezel" subwoofer.
As I said, most subwoofers need a box. So let's talk about the box!
First of all, what types of boxes are there?
Seal: The simplest one. Basically, the sealed box is a box that is not connected inside and outside. There are no holes and care is taken to ensure that the box is completely sealed.
Porting: The transplanted box is a subwoofer box with at least one hole or "port". The goal of porting a box is to emphasize a certain frequency. These boxes are used because they are usually louder than sealed boxes.
Bandpass: A pass-through box is similar to a box with a port because it has a port; however, the band-pass box attempts to no longer emphasize certain vacancies while highlighting other vacancies. In other words, it works like a bandpass crossover. The band pass box emphasizes the frequency band while emphasizing the frequencies below and above the frequency band.
Isobarik: These boxes are designed to mount multiple subwoofers into a small box. The subwoofer is set to work in tandem. Sometimes two subgroups move in the same direction at the same time, sometimes one subgroup pulls and the other subgroup pulls. This type of setup has advantages, but the box design is difficult.
Ok, so now you know everything about SUBZ, but here are the specifications for the subwoofer you need to know:
Power handling: Subs are speakers, so you can only handle so much power [or distortion] before they blow! Power processing is measured in watts and is usually given in two sizes: RMS and Max [or peak]. The RMS rating is the most important. If one says it can handle 200 watts RMS and 400 watts maximum, then make sure the amplifier also provides 200 watts RMS. Not 400 watts RMS. Although sub can handle 400 watts, it can only handle this power in a short time. If you connect that sub to an amplifier that amplifies a 400 watt RMS, you will quickly ruin that speaker - because it is often exposed to 400 watts instead of a short burst of 400 watts. Are you digging? it is good.
Sensitivity: This word means exactly what you mean. In short, subwoofers with higher sensitivity will be louder than subwoofers with lower sensitivity when they are connected to the same amplifier. Specifications are in db.
Frequency response: You obviously want a subwoofer instead of dealing with various frequencies. However, the subwoofer has the most work at 100hz. If the subwoofer is playing until 20hz, you know you have a great sub-speaker. The good news is that even if it's not so low, most music won't. Sooooo, you will still be fine. I would say that it is more important to use low playback in DVD players and 5.1 sound systems. In addition, the frequency response depends on the box in which the subwoofer is installed. Well, so considering this, just choose a subwoofer that can handle the power and sound it the way you want.
Tapered material: This is actually a very important consideration when it comes to subwoofers. Because of the power of the subwoofer, you need a tapered material that can withstand a lot of abuse. I personally like metal such as aluminum. This is because the aluminum is light and hard, and it also produces a very compact and musical bass. I know that many subwoofer manufacturers use exotic sound materials for their subwoofers, which makes it difficult to determine which material is the best.
Surrounding material: Here are my suggestions: always get a subwoofer with a rubber surround. Rubber remains in optimum condition in the automotive environment.
Impedance: measured in ohms, this specification tells you how much the speaker is impedance to the amplifier. Too much, you don't have volume, too little, your subwoofer will fire your amp! This specification will help you determine which amplifier is connected to the subwoofer, whether to bridge the amplifier, and whether multiple sub-connectors are to be connected in parallel or in series. In addition, subwoofers sometimes have more than one voice coil [aka DVC]. This means that the subwoofer will have two inputs, each with the same impedance. Subwoofers with dual voice coils can be installed more flexibly, especially in multiple subwoofer systems.
The basic subwoofer installation is quite easy. If you buy a pre-made sub-box, install them and power them, you get a good bass. To be professionally installed and get the best sound, you have to do a lot of planning and work throughout the process. In this case, if you have no confidence in building the boxes, adjusting the boxes and connecting them, you should visit the car audio store and have them do it for you. This can be reliable cheap or very expensive.
If you plan to install it yourself, but lack the box making skills, you can purchase a prefabricated box. I also highly recommend using an EQ device to fine tune the bass. This will help you overcome road noise [destroying the bass] and reduce "fluffy" and "turbid". Finally, this route is the best compromise between custom boxes and prefabricated boxes. You will hear great sounds and save money!
Now relax on those ears!
