Quick Summary of Key Points

When purchasing a subwoofer, it is important to consider the size, type, power output, and sensitivity rating of the speaker. Additionally, consider your budget as well as the structure and features that the subwoofer offers in order to make sure it meets your needs.

Subwoofer Size & Bass Output

When selecting a subwoofer, size and bass output are two important components to consider. A larger subwoofer typically offers more bass output, but this isn't always the case. Some people may debate if the size of a subwoofer compared to its power is what really matters.

However, it’s important to keep in mind that bigger doesn’t always mean better. In fact, many users have discovered this does not necessarily translate to sound quality as much as it does with other components of an audio system. While the typical rule of thumb is that bigger is better when it comes to subwoofers in terms of bass output, this isn't necessarily defendable with hard evidence.

When evaluating powered subwoofers, look at the wattage, frequency range and overall efficiency ratings for fair comparison rather than focusing solely on size. Different speaker manufacturers will also have different philosophies on size vs. power when it comes to designing their models. Therefore, do your research before deciding on a specific model so you can seek out one that suits both your desired sound output level and available space constraints.

Ultimately, as you can see, deciding how big and powerful a subwoofer should be requires consideration beyond just pure size and power specs. As we move forward it's important to consider how much space you have available for the subwoofer in order to choose the right model for your setup.

How Big Should the Subwoofer Be?

Now that we have a better understanding of the size and bass output of subwoofers, the next question to consider is: How big should the subwoofer be? This is a hotly debated topic, with many enthusiasts adamant that bigger subwoofers will always offer better sound quality. However, some disagree, citing room placement restrictions or overall system balance as reasons why larger subwoofers may not be beneficial in certain cases.

Those who prefer larger subwoofers point to the capability for bigger drivers to move more air, which allows them to reach deeper bass frequencies. This can be especially helpful if you’re more focused on deep-bass sound effects than music reproduction. Additionally, larger subwoofer enclosures provide an extended “airspring” effect when the woofer is driven by powerful amplifiers. This compression effect is sometimes lost with smaller boxes.

On the other hand, there are circumstances where bigger may not always be better. For one, in most home theater systems it’s important to get a good balance between all channels – including your subwoofer – so that everything sounds cohesive. Particularly when working with smaller rooms, a big driver can overwhelm the room and muddle up deeper audio details. Furthermore, a small enclosure has advantages due to it being easier to place and less intrusive compared with large cabinets with huge drivers taking valuable real estate away from wherever it's placed in.

At the end of the day, selecting the right size subwoofer depends on several variables like room size, aesthetic needs and available low frequency content among others. As such, finding the ideal subwoofer for your space and situation is highly subjective and requires careful consideration since having too much or too little bass could both negatively affect sound quality and musical enjoyment. With these factors taken into account, it’s time to start shopping for the perfect subwoofer that fits not only your taste but also your budget – something we’ll talk about in detail in the next section.

Selecting a Quality Subwoofer

Now that you’ve considered the size criteria for your subwoofer, it is essential to also consider the quality of the subwoofer when selecting one. It is important to remember that not all subwoofers are created equal; there is such a variety of quality, even within the same price range. Many people debate that higher priced subwoofers are always better than lower priced ones but that is not always the case. Often times it is worth it to invest in a slightly higher priced option since it typically means a better sound quality.

When determining which subwoofer will have the highest quality, experts suggest taking into account how much power and sensitivity it has, the amplifier type featured and what type of driver is included. Pay attention to specs such as frequency response and look for details about durability, crossover control and installability to get an idea of how well-crafted each product is. Moreover, be aware that people tend to naturally underestimate how powerful their systems should be - be sure to make sure your choice of amplifier can handle your chosen speaker effectively. The last thing you want is having an underpowered system and damage your speakers with too much power at once.

With all these points in mind, anyone can find a high quality subwoofer by carefully analyzing its components and features before making the purchase. Understanding what key components make up superior sound systems makes all the difference in getting a quality listening experience. Now that we have discussed which qualities to look for in a subwoofer, it's time to turn our attention to what factors might influence you when buying one.

What to Look for When Buying

When choosing a subwoofer, it is important to consider the size of the speaker. Larger subwoofers usually provide deeper bass, and may not be suitable for smaller rooms. On the other hand, a smaller subwoofer could be overwhelmed by too much bass in a larger space. This is why many audio experts recommend finding a balance between size and power when selecting a subwoofer. Regardless of the size, make sure that the construction of the subwoofer is solid enough to handle extreme amounts of bass. Consider factors such as size, durability, enclosure type (ported or sealed) and how many drivers it includes. If you are considering buying multiple subwoofers for your system, look into whether they allow for dual-mono or stereo setup - this can enhance the low frequency range.

Once you have decided on your subwoofer, it is time to move onto amplifiers and specs considerations. Beyond selecting particular specifications for amplification and power, quality control should be top priority. The amplifier must meet certain minimum standards in order to ensure that your system will perform as expected. It is thus essential to take some time to research appropriate amplifiers and specs before investing in your setup. Furthermore, remember that these components should be chosen on an individual basis, as what works well for one system might not work for another – do some trial-and-error testing with different combinations of woofers and amps to find the optimal solution for you.

Amplifiers & Specs to Consider

After narrowing down the type and size of subwoofer to consider, the next item of business for shoppers should be considering an amplifier and specs associated with it. An amplifiers technical specifications will likely be difficult for many buyers to understand, so it's wise to consult with an expert or do some research online about what type of amp makes sense for their system.

For example, shoppers should think about adding an extra power boost if they intend on using a subwoofer in a large space or event venue. Alternatively, if being used for home theater or general listening purposes, then having enough power on hand is essential. General guidelines suggest amp outputs of at least 20 watts RMS per channel in a stereo setup. If adding more subs to the home theater environment, then increasing the power output is recommended for maximum sound quality enjoyment.

When it comes to selecting an amplifier with the right specs, there are two schools of thought: those that select an amplifier based off power output versus those that look closely at current delivery ability and wattage needs. Each school has its advantages and disadvantages based on individual use cases and a list of requirements that need to be met. For instance, a buyer looking to buy an amp for use in an outdoor venue might prioritize higher power output capabilities which could drive larger subwoofers in louder settings. On the other hand, someone looking for a more customized listening experience across multiple subwoofers might emphasize current delivery abilities along with adequate wattages needed by each subwoofer over higher powered amplification options.

Decisions made during the amplifier selection process have important implications for sound quality results, so this is an area where close consideration should be taken before deciding what route to take. Now that we've outlined amplifiers and specs to consider when shopping around for subs, let's turn our attention to another important factor in getting maximum sound performance from our subs: power output & wattage needs.

  • Most subwoofers have a frequency response range of 20 Hz - 200 Hz.
  • Most home theater subwoofers feature an amplifier, typically between 50 and 250 watts.
  • A higher power (watts) rating generally means that the subwoofer will be able to produce louder, more powerful bass.

Power Output & Wattage Needs

When examining the specific power output requirements for your subwoofer, it’s important to consider the wattage needs of the space you are attempting to fill with sound. Amplification can drastically affect sound quality and is determined by the RMS power rating as well as peak power ratings that relate directly to a speaker's ability to efficient reach low frequencies and loudness. To ensure that there is ample power for the subwoofer to produce sound, many prefer an amplifier with higher than average peak or RMS power ratings.

It may be argued that using higher wattage than needed is inefficient, since it requires more of a monetary investment for little return, especially if you do not plan on running at full capacity. However, one should consider what their desired level of performance is. A higher powered speaker can go louder and have more control over lower frequencies, which would be beneficial if they want to easily add bass to their existing system without overpowering it. Additionally, some argue that having more wiggle room with wattage ensures that you won’t run into impedance issues from signal loss or distortion when listening at very loud volumes.

It is important to take note of these considerations when shopping for a new subwoofer in order to get the most out of your audio experience. Once sure that your setup can handle your desired levels of output and performance, it is time to move onto box and mounting considerations as you move closer to creating your ideal home theater or music system.

Most Important Highlights

When considering a subwoofer for your audio needs, be sure to factor in the RMS and peak power ratings that reflect the level of performance desired. Having an amplifier with extra wattage can prevent impedance issues when turning up the volume, but it is important to balance the wattage needed with the budget. Once you have taken into consideration power output, box design, and mounting, you can move closer to building your ideal audio system.

Box & Mounting Considerations

When selecting a subwoofer for your audio system, the box and mounting considerations are just as important of a factor as power output and wattage needs. To accommodate the low frequencies, the size of the subwoofer enclosure should be large enough to ensure a smooth transition between midrange and low frequency sounds. Furthermore, this box should also offer ample air space to allow for optimal performance of the device, therefore preventing speaker distortion or sound artifacts. Not only that, but it is important to consider what mounting option is available in regards to making sure the subwoofer is securely fastened and won’t move whether from loud vibrations or other causes. In terms of debate, some might argue that smaller enclosures can achieve adequate acoustic performance, while others feel it is necessary to use larger enclosures for low frequency reproduction to be up to par. While it is true that larger enclosures will provide more capability for louder output and deeper bass response, there have been several examples where smaller enclosures have produced ideal sound quality results; thereby allowing for great audio capability at a lower cost.

Regardless of which side of the argument you prefer, it is always important to consider box size and mounting availability when making your subwoofer selection - not only in terms of your requirements but also what would be most feasible given your budget or other restrictions. With that being said, however, in order to get an accurate listening experience from your choice you must also take into account conversion and audio range frequencies as those will ultimately decide what type of performance you can expect from your subwoofer.

Conversion & Audio Range Frequencies

Once you’ve decided on box and mount considerations, it is important to determine the conversion and audio range frequencies you need for your subwoofer. Frequency response is the measure of bandwidth between the lowest frequency and the highest frequency that a subwoofer can reproduce. Generally, most home subwoofers are designed for bass frequencies between 20 Hz and 250 Hz, while car subwoofers are usually better suited to frequencies lower than 50 Hz.

There is a lot of debate about what frequencies are acceptable when pinpointing conversion and audio range frequencies. Some believe that all bass should be identified and audibly heard. Others disagree arguing that allowing low-frequency bass sounds to remain either undetectable or muffled creates more accurate sound reproduction. It may come down to personal preference in whether to seek a wide range of audible frequencies or sacrifice some accuracy for smoother sounding music/movies.

In either case, the improved quality of sound created by having an appropriately optimized subwoofer is immense. If you are looking for an overall better sound experience without huge changes in hardware, then investing in a good subwoofer is highly recommended. Additionally, if space is limited selecting a subwoofer with existing dimensions as close as possible to the area available will likely result in improved results with reduced noise levels.

Having examined box & mounting considerations and conversion & audio range frequencies, we now move towards our conclusion of Subwoofer Shopping 101. With the right research and knowledge about what needs fitting into your desired setup, you should feel well equipped by the time you make your purchase decision.


When it comes to subwoofer shopping, it is important to understand conversion and audio range frequencies and how they are related. You should keep your audio frequency range in mind when selecting a subwoofer as it determines what sounds can be heard with clarity. You also need to consider the type of conversion that you wish to utilize – analog or digital – when deciding which subwoofer will meet your needs.

Ultimately, what’s most important is finding a subwoofer that gives you the sound quality you desire while still fitting into your budget. For those who value accuracy over power, a high-end digital converter is ideal. On the other hand, for those seeking stronger bass and more powerful lows, an analog converter may fit better.

No matter which type of conversion and audio frequency range you choose, make sure that you have taken the time to research all of your options before making your purchase. Investing in a quality subwoofer will allow you to enjoy accurate and clear sounds for many years to come.

Answers to Frequently Asked Questions with Detailed Explanations

What sort of power output should I need for my systems?

The power output you need for your system depends on several factors, such as how large your listening area is and the efficiency of your speakers. Generally speaking, you should aim for a power rating that is at least twice the sensitivity rating of your speakers. This will provide enough volume levels to fill your entire room without distortion or clipping. Additionally, you may want to look into amplifier classes when selecting an amp since they affect sound quality. Typically, Class D amplifiers are more efficient than other types and are a good choice if you're looking for enhanced bass with minimal power consumption.

What size subwoofer do I need for my room?

When it comes to selecting the right size subwoofer for your room, there are a few key factors to consider. Firstly, the size of your room should determine what type of subwoofer you need; if your space is large, then a larger woofer with more power would be better suited, whereas a smaller space might require a smaller woofer with less output. Secondly, the type of music you listen to also plays an important role in determining the size and power of the subwoofer. If you enjoy heavy bass music, then opting for a larger and more powerful woofer is likely the best option.

What are the key differences between various types of subwoofer?

When it comes to subwoofers, there are a few key differences that should always be taken into account. The primary difference between subwoofers is power and size.

For starters, the wattage of a subwoofer determines its power output. More watts means more output, though many factors such as driver design also play a role in determining how much sound will come from the speaker. A higher wattage means the speaker is better-suited for use in larger venues where high volumes are desired. Conversely, lower wattage subwoofers are best used in smaller settings.

Size is also an important factor that should be taken into consideration when shopping for a subwoofer. Here, we’re talking about both physical size (the size of the actual unit) and frequency response (how low the sound can go). Larger components typically have longer throw capabilities and can produce bass at lower frequencies. However, depending on the acoustic environment, bigger may not always lead to better sound.

Finally, another key difference between subwoofers is their driver configuration. Subwoofer designs range from powered, sealed and vented designs - with each offering its own advantages and drawbacks when it comes to sound quality. Make sure to research all these different types of drivers before making your decision as each type has its unique strengths and weaknesses when it comes to bottom-end reproduction.

By keeping these aspects in mind, you should have no problem finding the perfect subwoofer for your needs!
