Subwoofer Information: Find out About Auto Audio Subwoofers

Subwoofers. The bass. The loudness. The glory. The most obnoxious ingredient in your process, and also, just one of the most essential.

If you’ve study my article about speakers, you might be up to velocity. If you have not (and don’t know anything about speakers or subwoofers), go through it below.

Subwoofers reproduce the lowest frequencies of the audio spectrum, AKA bass. They are vital to equally SQ and SPL methods, but for distinctive good reasons. Let’s take a glimpse now…

For SQ units: Successfully reproduce the cheapest frequencies creating the tunes sound full and strong. Instruments that play decreased frequencies these as organs, drums and synthesizers will seem more sensible and powerful with a subwoofer mounted.

For SPL programs: Because subwoofers are loud, they are the most popular speaker to make a entire lotta sounds.

Also, since our ears are a lot less delicate to reduce frequencies we have to have the additional bass for the system to audio balanced.

So, what do I have to seem for to come across a fantastic woofer? I am going to explain to you!

Ability Managing:

Just like with each individual other aspect in a stereo system, electricity dealing with is essential for subwoofers as effectively. Earlier, in my posting about speakers, I talked about how you can send far more power to them to increase their volume, but lessen the distortion. The identical is true of subwoofers, but be very careful! Since lower frequency distortion is tougher to understand, it really is effortless to overdo it, and blow your subwoofers. In any case, with that claimed, it is good to get an amp that can place out exactly what your subwoofers are intended to acquire, but consider it easy!


Subwoofers arrive in a lot of measurements, but the most frequent are 8″, 10″, 12″, and 15″. This is likely also noted in metric for the european brand names. As you can envision, the greater woofers are the ones that will participate in louder and perform decreased. Of course, the lesser kinds are much more musical, extra exact, and audio “tighter”. What measurement you come to a decision on usually has to do with your very own tastes, as properly as installation criteria. Recall! 18″ subwoofers really don’t just suit anyplace!

Voice coil info:

SVC: Single voice coil

This suggests that the speaker has only a single voice coil. In other words, only a person enter.

DVC: Dual voice coil

This means that the speaker has two voice coils, or two inputs.

Ummmmmmm, okay. Why does it issue?

I could go into specifics below, but I know you do not actually care. Mainly, it boils down to this: With a DVC subwoofer, there are far more set up choices. Search at it this way, a DVC “looks” like two subwoofers to your amplifier. With some nifty wiring methods (identified as series and parallel), you can hook up many subwoofers to a one amp–even if the amp is a “mono” or a two channel amp. In addition, you can manipulate how lots of ohms the amp has to press. If you have an amp that is stable to a 50 percent ohm (like some aged college Orion HCCA amps), you could perhaps hook up 4-8 woofers to a single channel! Visualize the sound you could make!

Some terms about packing containers:

Bins are vital to most subwoofers. In other words, think about a subwoofer’s box just as critical as the subwoofer by itself. Why? Simply because most subwoofers will need a box to work correctly, audio very good, and not destruction themselves. Subwoofers that do not need a box are called “cost-free air” or “infinite baffle” subwoofers.

Like I said, most subwoofers want a box. So, let’s discuss about boxes!

First, what kinds of packing containers are there?

Sealed: The most basic sort. Fundamentally, a sealed box is a box the place the inside of and outside the house are not linked. There are no holes, and treatment is taken to guarantee that the box is totally sealed.

Ported: A ported box is a subwoofer box with at minimum one particular hole, or “port” in it. The intention of the ported box is to emphasize a specific frequency. These packing containers are used because they are usually louder than sealed containers.

Bandpass: A bandpass box is similar to a ported box since it has ports nonetheless, the bandpass box tries to de-emphasize certain frequencies, whilst emphasizing other individuals. In other words and phrases, it works like a bandpass crossover. The bandpass box emphasizes a frequency band although de-emphasizing frequencies reduced than and larger than the band.

Isobarik: These bins purpose to fit far more than a single subwoofer into a smaller box. The subwoofers are established up to do the job in tandem. Sometimes both of those subs move in the exact same route at the same time, in some cases just one sub pulls while the other pushes. There are pros to this form of setup, but box design is hard.

Ok, so now you know all the things about SUBZ, but listed here are the specs that you’ll require to know to pick out your subwoofer:

Power Handling: Subs are speakers, and as this sort of can only tackle so significantly power (or distortion) ahead of they blow! Energy handling is measured in watts, and is normally given in two specifications: RMS and Max (or peak). The RMS ranking is the most crucial. If a sub states it can deal with 200 watts RMS and 400 watts Max, be sure the amp will deliver 200 watts RMS as very well. Not 400 watts RMS. Even though it truly is real that the sub can deal with 400 watts, it can only cope with that sort of power for a shorter time. If you hook that sub up to an amp that places out 400 watts RMS, you will ruin that speaker rather swiftly–simply because it is consistently becoming uncovered to 400 watts, not small bursts of 400 watts. You dig? Superior.

Sensitivity: This phrase means just what you consider it implies. In quick, a subwoofer with better sensitivty will be louder than a subwoofer with decrease sensitivty when they are hooked up to the similar amp. The spec is calculated in db.

Frequency response: You definitely want a subwoofer than can tackle a broad assortment of frequencies. Having said that, the subwoofer does the most work below 100hz. If the subwoofer performs all the way down to 20hz, you know you’ve got acquired a excellent sub. The very good news is that even if it isn’t going to go that minimal, most audio won’t possibly. Sooooo, you can expect to still be fantastic. I would say the it can be extra vital to have a low-participating in sub in programs with DVD gamers and 5.1 sound. Also, frequency response may differ based on the box that the subwoofer is mounted in. Ummmm, so with this in thoughts, just select a subwoofer that will cope with the power, and seem how you want it to.

Cone Materials: When it comes to subwoofers, this is in fact a very essential issue to spend attention to. Since subwoofers are significant and highly effective, you need a cone material that can face up to heaps and loads of abuse. I individually am a large fan of metals such as alluminum. This is simply because aluminum is mild and stiff, and furthermore, provides pretty limited and musical sounding bass. I know that lots of subwoofer manufacturers use unique sounding products for their subwoofers, which can make it challenging to determine which substance is the finest.

Surround content: Here is my guidance: Normally get a subwoofer with a rubber encompass. Rubber holds up the ideal in the vehicle natural environment.

Impedence: Calculated in Ohms, this spec tells you how significantly resistance the speaker presents to your amp. Far too a lot, and you get no volume, much too tiny, and your subwoofer will fry your amp! This spec will support you come to a decision which amp to hook up to your subwoofer, irrespective of whether you want to bridge your amp, and no matter if you want to wire multiple subs into parallel or collection. Also, subwoofers from time to time have a lot more than one voice coil (aka DVC). This suggests that the subwoofer will have two inputs, each individual with the same impedance. Subwoofers with dual voice coils are additional multipurpose to put in, primarily in many woofer systems.

A standard subwoofer install is pretty uncomplicated. If you get a pre-fab sub box, mount the subs and electricity them, you are going to get excellent bass. To set up professionally, and accomplish the greatest audio, substantially setting up and operate must go into the complete method. This is a scenario where by if you never feel confident in your capability to make a box, tune it, and hook it up, you ought to pay a visit to a motor vehicle audio shop, and have them do it for you. This can be fairly low-cost, or fairly pricey.

If you are preparing on accomplishing the install on your own, but lack the box building skills, you can buy a pre-fab box. I would also strongly endorse an EQ device to fantastic tune the bass. This will assist you prevail over street sounds (which ruins bass), and also cut back again on “boominess” and “muddiness”. In the close, this route is the most effective compromise among a custom box and a pre-fab box. You may get terrific seem, and help you save money!

Now go effortless on all those ears!
