What is a subwoofer?
If you have a subwoofer, then in that location must also be a woofer, right? Correct. Most woofers or regular speakers can merely produce sounds down to nigh 50 Hz . Subwoofers produce low-frequency sounds down to 20 Hz . Hence the name "woofer" comes from the deep, roaring sound that dogs make when they bark.
While the divergence between the 50 Hz threshold of most speakers and the 20 Hz threshold for subwoofers sounds trivial, the upshot is noticeable. Subwoofers permit you experience the sound of the bass in a song, picture show, or any other sound that you lot're listening to. The lower the low-frequency response of a subwoofer, the stronger and juicier the bass.
Because these tones are so low, some people actually aren't even able to hear the bass that booms out of a subwoofer. That's why the feeling component of a subwoofer is and then essential.
Young, good for you human ears are only designed to hear sounds with a frequency down to 20 Hz , pregnant that it tin can sometimes exist hard for middle-aged human ears to hear sounds that deep. With a subwoofer, even if you tin't hear information technology, y'all can certainly feel the vibrations.
How do subwoofers work?
Subwoofers connect to the other speakers in a full audio system. If you're playing music at dwelling house, you'll have probable connected the subwoofer to your audio receiver. When the music plays through the speakers, it'll transport depression-pitched sounds to the subwoofer to reproduce them effectively.
When learning about how subwoofers work, y'all might meet the two types, active and passive. An active subwoofer is also known as a powered subwoofer, as it comes with a congenital-in amplifier. Passive subwoofers crave an external amplifier. If y'all choose to go with a powered subwoofer, you'll need to invest in a subwoofer cable equally y'all'll have to connect it to the sound system's receiver, as mentioned in a higher place.
Y'all'll notice that in home theater sound systems, subwoofers are the largest speaker. Is bigger better? Yep! The larger the subwoofer speaker, the deeper the sound is going to be. Simply physically big speakers are able to produce the deep tones you lot hear coming out of a subwoofer.
What about the vibrations? How does that work? The effectiveness of a subwoofer largely depends on the placement of information technology. Expert audio engineers suggest placing subwoofers:
Nether furniture . If yous actually want to feel the vibrations coming from deep, rich sounds in a film or musical piece, placing information technology nether your furniture, such as a burrow or a chair, can heighten those sensations.
Side by side to a wall. Place your subwoofer box next to a wall and so that the approachable sounds reverberate off the walls and strengthen the bass.
How to choose the best subwoofer
Similar to regular speakers , subwoofers come with specs that brand a difference in the purchasing process. Depending on what y'all're after, here's what to look for.
Frequency range
The lowest frequency of a subwoofer is the lowest sound a speaker driver can produce. The highest frequency is the highest sound the driver tin attain. The all-time subwoofers will produce sounds as depression every bit 20 Hz, simply it'south essential to await at the frequency range to get a good idea of how the subwoofer will fit into the stereo system as a whole.
Sensitivity
When looking at the specs of pop subwoofers, look at the sensitivity. This indicates how much ability is needed to produce a detail sound. The higher the sensitivity, the less power a subwoofer will need to produce the same low-pitched sound as a speaker at the same level.
Enclosure type
Enclosed subwoofers that are already built into a subwoofer box will tend to give you deeper, fuller sounds than those that aren't enclosed. Ported enclosures are better for louder sounds, but not necessarily deeper tones.
Impedance
Measured in Ohms, impedance relates to a device's resistance to the audio source's current being pushed through. Most subwoofers have 4 Ohms of impedance, only you can likewise observe 2-Ohm and viii-Ohm subwoofers.
Phonation coils
Near subwoofers come with single voice coils, but truly experienced or enthusiastic sound junkies often opt for dual voice scroll subwoofers. With two voice coils, you lot're able to wire the sound organization equally you lot see fit.
Power
When choosing the best subwoofer, be sure to check out the power rating. In subwoofers, the RMS ability rating is more important than the top power ratings. This is considering it measures the continuous power as opposed to superlative power. If y'all have an amplifier already, brand certain the subwoofer you're looking at can handle that ability output.

Notwithstanding, those subwoofers are commonly too small to handle the everyman frequency sounds a actually practiced subwoofer might handle.
Then, it helps to figure out what you're looking for out of the subwoofer. Things like dual vocalization coils, enclosure type, and impedance are all factors to consider as they affect the overall sound and compatibility with the amplifier and other speakers yous currently have in the car.
Really, what you'll want to wait at are the types of subwoofers .
Component subwoofer
This is just the speaker, which ways yous'll notwithstanding demand to install it in a subwoofer box and ability information technology with an external amplifier. Component subwoofers are great for customizable sound systems as they come in a variety of sizes and with a variety of features (impedance, voice coils, etc.).
Enclosed subwoofer
As the name suggests, these subwoofers are enclosed in the box already. While this is more than convenient, it limits the number of choices you have in terms of customization. Similar to the component subwoofer, though, you'll still need to buy a separate amplifier.
Powered subwoofer
Nosotros talked about these before. Remember? Powered subwoofers are active in that they have an internal amplifier that means there's less wiring involved in the installation. Because of this, they're pretty compact and make a great addition to a automobile stereo arrangement that only needs a piddling actress bass heave.
Subwoofers for home theater systems
The biggest difference between subwoofers for cars and subwoofers for domicile theater systems is the size. SVS habitation theater sound systems come complete with SVS subwoofers ranging from 12-inches all the manner upwardly to xvi-inches .
The SVS SB-2000 Pro is an elite subwoofer optimized for deep bass product, churning out vibrating sounds that'll get deeper than even the 20Hz human hearing threshold. And, the PC-2000 Pro stands at 34-inches alpine, offering a unique take on the traditional subwoofer box that most are accepted to.
