What is a Subwoofers?

A subwoofer - also known as a bass box or woofer - is a special speaker box that can be integrated into a home speaker set. The subwoofer is responsible for the reproduction of low-frequency sound waves, i.e. for very deep tones, and offers a suitable sound experience. In the end, it's nothing more than a deep bass reproduction that produces a distinctive rumble in the belly area.

Many still believe that a hi-fi system is perfectly adequate. There's ample top bass here. But when it comes to deep tones, most squares are very weak. Normal squares can't keep up, especially at frequencies of 30 Hertz or lower. But the low frequency range is usually present in many recorded music and motion pictures and is lost if the loudspeakers can't reproduce it.

Indispensable bass box for "real" deep tones: With movies or music, bass ensures an exceptional sound experience. Especially with action movies or hip-hop music, the low notes are not to be missed in order to get a feel for the movies and music in the truest sense of the word. Deep sound is created by the movement of large air volumes, which the subwoofer is responsible for. It is always added in addition to the usual speakers. The latter usually cannot reproduce the low frequency range and must be coupled with a subwoofer to experience the low notes up close.

How do subwoofers work?

Basically, the subwoofer functions like a regular speaker. That is, it is able to convert the electrical vibrations from the playback device into large waves in the air. The incoming audio signal is first converted by the sound converter in such a way that the loudspeaker can process it from digital to analog signals. At the same time an amplifier is used to amplify a weak signal.

Prepared in this way, the signal reaches the voice coil, which is located on a strong magnet. This in turn is attached to the loudspeaker membrane. Due to the mutual influence of the magnetic field of the voice coil and the magnet, the membrane begins to move. By doing so, it picks up an electric signal beat. As a result, the air vibrates and sound waves are created, which the human ear perceives as pitch.

For deep tones, a lot of air has to be moved - and this is where the subwoofer comes into play. It is responsible for low frequency sound, also called bass. Since this requires a large membrane area, the bass box is made larger. If integrated into the music system, the frequencies are automatically passed to it when they enter a certain frequency range (frequency limit) falls below. It depends on how the system is configured.

What is meant by cutoff frequency? This term refers to the threshold at which the subwoofer takes over. The upper limit frequency is usually below the frequency range of about 100 Hertz. The lower limit frequency represents the lowest frequency range the woofer can reproduce. With a good subwoofer is 25 to 30 hertz or less.

Which subwoofer is suitable for home cinema?

With blockbusters and action movies, deep tones and clear bass deliver a "cinema" experience right at home. Therefore, a subwoofer that covers a lower limit frequency of 30 Hertz or less is very useful. In addition, the active subwoofer significantly reduces the other speakers in the system, which can cover their own frequency range better and uninterrupted. This allows a better sound image.

It is important to set up and connect the subwoofer properly and adapt it to the conditions of the room. Certain features also play a role in figuring out which subwoofer is best suited for home cinema. The following sections are intended to assist in the decision-making process.

What types of subwoofers are there?

There are many subwoofers used for different and sometimes very specialized applications:

• Home theater area
• Music enjoyment
• Car subwoofer
• PC subwoofer for gaming

In addition, subwoofers are available in various designs. Therefore, before you buy it should be clear whether the woofer should be used for home cinema, music or games. It depends on what is the best subwoofer for your needs. The two most important construction methods are described below and their advantages and disadvantages are listed.

Front-firing subwoofer with its advantages and disadvantages

Front-firing subwoofers can be recognized primarily by the clearly visible membrane. They also have a protective lattice on which the membrane is located. With Frontfire type sound waves are advanced. This means that the air around it and not the ground is made to vibrate. This is why this type of subwoofer design is mainly used by music fans, as the furniture, walls and floors barely vibrate at all.

This has the advantage that neighbors are not disturbed by vibrating bass. At the same time, the bass is "only" audible and not felt through the vibrations. Many find it more comfortable and less intrusive. In general, the front-firing subwoofer offers a very good sound experience and precise bass. Therefore, they are suitable for high-quality music enjoyment. If the acoustic effects are sufficient for the film, a front firebox is usually a good idea too.

Pros and cons:

Advantages

• Delivers precise bass and an excellent sound experience
• Often considered fun and unobtrusive
• Little or no disturbance to neighbors
• Great for music and movies

Deficiency

• No real effect of vibration
• Can slightly limit the experience with action movies & Co

Downfire subwoofer

The downfire subwoofer is ideal for home cinema enthusiasts. The membrane is not visible, the box is closed all around and there is only the speaker membrane at the bottom of the housing. Sound is emitted to the ground and distributed in a 360 degree range. This causes walls, floors and furniture to vibrate and the bass can be physically felt. This is the desired effect for many home cinema fans.

Caution: If you live in a clairaudient apartment building or an old building, you should be very careful when deciding on a downfire subwoofer and think about it carefully. Because vibrating floors and walls can sometimes be very annoying to neighbors and put great stress on neighborly relationships.

Anyone who loves action and wants to be right in the middle of the action while watching a movie will benefit from a down-firing subwoofer. Due to the even distribution of bass, almost none of the bass frequencies are self-extinguishing. However, in certain musical styles, such as classical music, where bass is not as important, the woofer can dampen other frequencies and reduce sound.

Pros and cons:

Advantages

• Live bass on walls and floors
• Very suitable for action films and blogbusters
• Very even bass distribution
• Bass is partially felt physically

Deficiency

• Can be very annoying neighbors
• With certain types of music, the frequency can be removed

Which is better - active or passive subwoofer?

With subwoofers, a distinction is also made between active and passive subwoofers:

1. Active woofers have built-in amplifiers and are much more compact. In addition, active subwoofers are much easier to handle, which is why they are mainly used in homes. In addition, an active subwoofer helps to lighten other speakers and is therefore the first choice for home cinema or enjoying music at home. Plus, more adjustments can be made to active bass speakers than passive woofers.
2. The passive bass box needs to be driven by an external amplifier. The way it works is roughly comparable to that of an ordinary speaker box. Passive subwoofers are set directly on the amplifier, which is why they are commonly used in cars. Passive woofers are also usually much cheaper than active versions.

Passive for cars - free air subwoofer: Bass boxes do not have a housing and are usually intended for cars. Subwoofers for cars are also mostly passive woofers. They are usually mounted in the trunk, with the interior of the vehicle serving as a sound box.

What is the role of the woofer housing?

The loudspeaker housing, also called the chassis, is very important for sound. Two construction methods have prevailed in recent years. On the one hand, the housing is closed, as is the rule with normal loudspeakers. On the other hand, there are designs where there are openings on the front or back.

Closed housing

The closed case offers deep, precise bass. In addition, it only contains a limited amount of air. Therefore, it tends to have a very precise bass response. Muted, clean and low-frequency sound is precisely reproduced. Enclosed subwoofers make sense for music fans who want flat and accurate frequency reproduction without erratic character.

Another advantage of closed cases is their compact size. The disadvantages of the design include that the efficiency and level of stability is lower than that of other devices. This increases power requirements and at the same time reduces sound pressure.

Open housing

If you need majestic bass for action movies, you can go for a subwoofer with a bass reflex aperture served very well. It often produces erratic bass, which is why it is perfect for movie buffs and for home theaters. The openings on the front or back of the open design have the task of amplifying certain frequency sounds. In doing so, he used the Helmholtz resonator principle.

Helmholtz resonator: The principle named after Hermann von Helmholtz is most easily explained using the acoustic effects of everyday life. Blowing into the bottle makes a sound. If the volume of the bottle is changed, the pitch of the sound produced also changes.

Sound waves emitted from the rear wall of the speaker cone amplify the resonance in the body of the room (in this case the speaker cabinet) and exit through the opening. At the same time, this means that the housing must be very well matched to the speaker to achieve the desired effect.

Whoever decides on the design will benefit from excellent level stability, low power consumption and high efficiency.

What to consider when setting up a subwoofer?

If you have a bass box, you should pay attention to a few things when setting it up. On the one hand, neighbors should not be disturbed and, on the other hand, the sound experience should be perfect. Therefore, the position of the woofer is very important. The frequencies emitted by the subwoofer cannot be detected by the human ear. Therefore it can theoretically be positioned anywhere in space. However, not all places are equally suitable as a place of installation.

The recommendation from most manufacturers is to place the woofer in front between the center speaker and the right or left speaker. This creates an almost equal listening distance to all the integrated speakers. This also makes sense since the speakers on the right and left also partially emit low frequencies.

If the above-mentioned mounting position is not possible because the speaker system is in a rack or wall unit, for example, then another solution is required. Because often there is no more room for a large subwoofer in this installation location. There are three possibilities here:

• Position it at 1/5 the width and length of the room - far enough away from the wall and also allow varying spacing to avoid sound problems.
• Place it in the center of the room - the sound is considered very homogeneous, with the woofer close to the center speaker.
• Accommodates under furniture - some narrow subwoofers offer the possibility of placing under the sofa & Co, which is both space-saving and effective.

Caution: Placing the subwoofer behind furniture or plants is considered unprofitable. In addition, they should not be placed in the corners of the room. This is where sound waves collide from all directions. This results in unwanted reflection of sound waves and the bass begins to boom excessively. A similar problem, only to a lesser extent, can also occur with direct placement on the wall.

3 Tips for placing a subwoofer

To conclude the important topic of where is the best place to place a subwoofer, three quick tips:

1. Before finalizing the placement, try where it sounds best, always use the same music for proper comparison.
2. Basically, the woofer is positioned correctly when it's no longer audible from the other components of the loudspeaker system - the bass should be in sync with the other box instead of dominating it.
3. It can be helpful to get a suitable enough cable for the subwoofer beforehand. The supplied cable is often too short, which can limit the choice of location.

Please note: To increase the life of the built-in subwoofer amplifier and reduce its power consumption, the active subwoofer volume is set to approximately 35 percent to a maximum of 50 percent. The overall volume can be adjusted later on the AV receiver.

Connect the subwoofer properly

As a rule, manufacturers provide detailed operating instructions that explain how to properly connect and set up the bass box. Below are some general tips and pointers on the subject, which, however, only refers to active subwoofers. Fortunately, almost no technical knowledge is required for this, as it is a standalone bass system.

The most important thing is the cinch cable you need. It comes with one end going into the soundbar or AV receiver. The latter is often labeled "Sub out", "Sub" or "Subwoofer". The other end of the cinch cable plugs into the appropriate connection on the bass box. This can be a mono or Y-RCA cable - both will work. RCA Y cables have two connectors attached at one end.

If the signal transmitter does not have a cinch connection, it can be connected with a normal loudspeaker cable (jack plug). After connecting the signal transmitter (AC & Co receiver) to the subwoofer, the subwoofer just needs to be plugged into the mains and ready to go.

Note: If the subwoofer has two cinch inputs (usually marked in red and white), a mono cinch cable will suffice. It goes into one of the jacks, which is usually labeled "Mono". While the Y-cable can provide better volume, it can also be easily adjusted on the level control.

What to consider with a subwoofer - some safety tips

To protect the woofer and for your own safety, certain behavioral measures must be taken into account - please also pay attention to the manufacturer's instructions. The most important safety instructions are as follows:

• Do not place near a heat source
• Don't get wet
• Use only undamaged connection cables
• Don't make any changes to the bass box
• Only connect to sockets intended for this purpose

What frequency should the subwoofer have?

The lower frequency limit for some woofers is 25 hertz or lower, while others reach the limit at 35 or 45 hertz. Basically, the lower the frequency range, the stronger the physical perception of the bass sound effect in a home theater.

The same goes for the bass of a hip-hop song or electronic music. They radiate specifically and powerfully from the bass box at a lower, lower cut-off frequency. Other music genres such as rock or classical, on the other hand, hardly reach such deep bass. Anyone who primarily listens to this type of music will also notice the excellent sound at 40 Hertz.

Which subwoofer is the best - the most important buying criteria

The following sections explain which subwoofers are worth buying. A detailed comparison of subwoofers is helpful to find the best one for your own needs. The following criteria play a role in this context.

Types and kind

An active subwoofer is perfect for home use is recommended. Passive woofers are more suitable for enjoying the sound in the car. When making the right choice, it's also important to know if it's a down-firing or front-firing subwoofer. The previous section provides more information on this.

Construction

The closed and open constructions (bass reflex) have been described above. While the latter subwoofers produce deeper, more powerful bass, they can show weakness with slightly higher bass. The closed design can be especially useful for very small loudspeakers that are powered to produce higher bass.

Important: It should be remembered in this context that subwoofers in enclosed designs are more expensive for the same effect as bass reflex woofers and also require more watts.

Size

In general, the rule applies: the larger the cabinet, the more powerful the subwoofer. Because the bigger, usually the better the technology in it. However, many other components come into play when it comes to sound quality, so the smaller version can also be of high quality. In addition, larger woofers take up more space, which should also be taken into account.

Ingredient

The housing must be strong and made of high-quality and scratch-resistant materials. Typically, the subwoofer frame is made of MDF which is stable and thus offers a certain amount of sturdiness and stability.

Another important criterion is the legs of the subwoofer, because the woofer should not stand directly on the floor. Therefore, the feet should ideally be height-adjustable to get the best sound results.

Processing

Improper processing can be recognized, for example, by incorrect weld seams, corner transitions or frayed covers. A stable switch or knob is also important.

Frequency

There is already information about the appropriate subwoofer frequency in the previous section. The lower cut-off frequency of 30 Hertz or less for high-quality woofers is very attractive. In some cases, a value of 40 Hertz is sufficient if very deep bass is not a major factor.

Sound quality

In the end, you can only find out in practical tests whether the sound quality meets your expectations. Some other customer experiences can help. Fortunately, when buying online, there is an option to return it if the subwoofer does not deliver the desired quality.

Therefore it makes sense to check the sound properties immediately after delivery. It's important to check playback for frequently used applications later - for example with different movie scenes or different genres of music.

Listen carefully: It is important that the bass notes when listening to music are reproduced ideally with lots of power and very clean. There should be no distracting background noise, additional noise or noise afterward. You should also pay attention to the quieter sound reproduction and how the subwoofer reproduces the higher tones.

Performance

The bigger the diameter of the woofer, the bigger the punch and the more air it has to move. The subwoofer requires the appropriate amount of power. Your value in watts gives you a clue. Sometimes there is a two-watt specification. In this case, lower means nominal power - also continuous power or Watts RMS - and higher for possible short term maximum power at dynamic peaks.

Settings options

The subwoofer electronics are primarily responsible for good deep bass capability. This includes a variety of must-have setup options where possible:

• Adjust volume
• Crossover frequency control
• Phase control or phase reversal
• Extended filter function

Connectivity

As already explained, apart from the power connection, the cinch connection is the most important connection option for a subwoofer with a receiver, etc. The so-called jack plug, which is used to connect headphones or speakers, is also possible. A high-level connection is also used for the latter. The possible AUX input is used to amplify the incoming audio signal.

Do bluetooth subwoofers make sense? If you want to be independent from wired connections, you can choose a subwoofer with Bluetooth. It usually delivers good to excellent quality, but it never works without loss. High-quality transmission standards or Bluetooth codecs, by which audio signals are transmitted, are important for Bluetooth subwoofers.

Design

The color and shape of the subwoofer also plays a role in the selection - after all, woofers are bulky and eye-catching. Bass boxes are usually designed in neutral colors such as black, brown or white and have a square shape. Those who appreciate a more unusual design can use a subwoofer with a rounded shape.

Possible fault with subwoofer

If the bass box is no longer delivering the desired quality, this could be due to a variety of reasons. Some possible sources of error and suggested solutions are listed below.

Subwoofer hums: Unsightly hum instead of clear bass can be caused by the power supply unit or interference with the power supply, for example. In the latter case, it might help to try a different outlet. Sometimes the cable is laid in an unfavorable way, and then the possibility of tangling of the cable must be eliminated.

The so-called ground loop can also be the cause. It sometimes occurs when a signal device is connected to a subwoofer or other connected source device. In this case, a certain power filter should fix the problem.

Subwoofer scratches: If there are hard scratches, it may help to gently press the membrane down the middle. Erratic streaking may be due to poor centering, which should then be checked. It may help to press the membrane a little in the middle.

Loud noise when powered on: The power supply should be checked. Installing a capacitor can help.

No sound at all: The subwoofer may overheat and activate the overheating protection. A short circuit caused by bare wires or the like can also be the cause.

Caution: Never open and disassemble the subwoofer yourself. You must not make any changes to the bass box yourself. This is not only dangerous, but can cause irreversible defects. The manufacturer then does not accept the guarantee. If something goes wrong, it is best to consult an expert.

Frequently asked questions about the subwoofer

Which subwoofer brands and manufacturers are good?

There are many subwoofer suppliers. The most important and well-known manufacturers and brands of bass boxes are as follows:

• Canton
• Devil
• Evil
• Magnate
• Blue point
• Yamaha
• Clip
• Nubert
• Alpine
• Magnate
• JBL

Which is the best subwoofer?

Not every "ear" is the same. While some people rate the bass box as bad, others actually believe it. Basically, it depends on your own needs. A good subwoofer should still have a certain frequency range closing down (lower limit frequency), which should be around 30 to a maximum of 40 Hertz - the lower, the better. This guide describes other important features in detail.

Where can you buy a subwoofer?

Major electronics stores and smaller local specialty stores offer woofers. It is usually possible to check the sound quality directly. In addition, professional advice can sometimes be used. However, the selection is often very few, so the right subwoofer is rarely found right away.

On the other hand, there is a large selection of woofers available on the Internet. This allows extensive subwoofer comparisons to find out which subwoofer is best for your own needs. In addition, there are often lower prices and convenient shopping from home. However, there is no advice from the specialist staff.

How much does a good subwoofer cost?

A good subwoofer doesn't have to be expensive. A powerful bass box is readily available for low three-digit sums. However, the price segment can also be well above this and sometimes close to the four-digit range.

Is it possible to make a subwoofer yourself?

Yes, with the appropriate skill manual and prior knowledge, you can build your own subwoofer. However, expertise is required to consider the correct parameters and properly match all components.

Which subwoofer for music?

Front-fire subwoofers with closed designs are generally great for music. More important, however, is the bass performance. If you often listen to bass-heavy music such as hip-hop or electronic music, you should pay attention to a lower cut-off frequency of at least 30 Hertz. Rock or classical music still sounds really good at 40 Hertz, because the focus here isn't on bass.

How should the woofer be cleaned?

Cleaning the subwoofer is not very time consuming. A dry or slightly damp cloth is suitable for removing dirt from the house. Dust from the membrane is best removed with a dry cloth. If there are dust or dirt particles in hard-to-reach places, compressed air can be used with caution. Cleaning agents containing alcohol, caustic or abrasive cleaning agents are not suitable.

Conclusion

Subwoofers are generally used to maximize the bass sound emitted by the speakers. What do you think about the explanation of how to choose and the recommendations we provide? Each product that we provide has its own advantages.

When buying the best subwoofer, we recommend that you pay attention in terms of SPL, impedance, frequency, and the box contained in the subwoofer. In addition, it would be better if you try to check first before buying.
