FAQ related to Best Under Seat Subwoofer

1. What are some other best locations for an under-seat subwoofer placement?

Ans. Under seat subwoofers usually come in small size since there isn't much room under a car seat. So, space is really not a big deal when it comes to these subwoofers, you can install them anywhere you feel convenient.

There is no limitation for them like gigantic subwoofers have. However, considering the path of output transition; car door, back of the seat and trunk are more likely the other best options for the placement.

2. What's the benefit of a powered subwoofer?

Ans. Built-in amplifier, of course. You already know the definition of the powered subwoofer, it comes with its own amplifier.

When you're using a powered subwoofer, you won't have to link an extra amp with the system for optimized frequencies, the built-in one takes care of that itself. Moreover, powered subwoofer's response sounds more intense.

3. Why it's compulsory for a subwoofer to be connected to an amplifier in general?

Ans. We use subwoofers for bass reproduction. More intense output means a much more enjoyable experience.

The amplifier takes the signal and amplifies it to go stronger, which results in the louder output. This is the core reason behind the addition of an amplifier.

4. Are all under seat subwoofer powered?

Ans. No. Both types are available for your convenience. To save your time, space and effort, powered subwoofers take the amplifier's responsibility on their shoulders. In case, you want a louder response, other subwoofers are always available.

5. What are the cons of inaudible low frequencies?

Ans. The term bass is used to refer to the range of low frequencies. The thing is, all low-end frequencies are included in the array, even the inaudible ones.

Now, even though some frequencies are inaudible to human ears, they still appear as signals and not quite the necessary ones. Instead, these frequencies contradict with the subwoofer configuration and damage the system.

6. What is a filter?

Ans. An important part of the subwoofer, in other words. The low-frequency range consists of a huge number of frequencies, but not all of them are necessary in order to reproduce ideal bass response. Some of them even play as the root reason for distortion.

To prevent unnecessary frequencies, filtering is required and this is where the filter circuit comes in handy. It allows only a certain range of signals to pass by and blocks other unnecessary frequencies from getting in the way.

7. What is the difference between high-pass and low-pass filters?

Ans. Both circuits work to separate the important frequencies from the unnecessary ones, but differently.

Low-pass filter blocks frequencies above a certain setting and the high-pass filter does the complete opposite, it blocks frequencies below a certain setting.

8. What is a subsonic filter?

Ans. Another important feature of the subwoofer. The subsonic filter takes care of the inaudible frequencies mentioned earlier. It blocks them from transitioning and makes way for high-efficiency bass.

Having Trouble Making Decision? Here's A Guide.

Still having dilemmas? We get it, making the right purchase is not always an easy piece of cake. And since we're talking the best under seat subwoofer here, conditions are a bit more complicated.

But as always, we got your back. Here are some tips to make it easier for you.

Things to Consider Before Buying

Space

When the discussion is about under seat subwoofers, the topic of space has to be discussed. In order to fit under the seat, the subwoofer has to be pretty compact. You just can't pick something random, have to measure the ratio carefully.

The under-seat subwoofer should be able to fit tight spaces. Not just what says in the name, it should come with the ability to fit other places as well.

Sometimes the area under the seat is not the most preferred location judging from the subwoofer's sound dispersion ability. So, it should include arrangements for the back of the seat, trunk, car doors and other shallow areas.

Power Handling

When you read about subwoofers, this doesn't seem like much, but the power handling is the most important thing here. More important than the size and the design.

The RMS wattage you see, it decides the loudness of the subwoofer's response. The bass gets louder as the number goes higher.

However, in case you're working with an additional amplifier, its capacity has to match your subwoofer's power handling limit. Otherwise, the amplifier won't be able to optimize the sound to an acceptable extent. Or worse, it'll burn your whole system down.

Frequency Response Range

Why is this important? The low-end frequency range is vast, and the production capacity differs from one model to another.

You can learn the subwoofer's sound playing capacity judging from its frequency response range. The range tells you how deeper or louder the bass can go. So, it's pretty important to learn about a particular subwoofer's frequency response range before making a purchase.

Amplifier

We're talking bass performance here! Come one, what was the deal in the first place?

Car's factory speakers (or car speakers in general) aren't really great when it comes to bass delivery. Seriously it's not easy to bring such power using drivers like them. That's why an extra subwoofer is required for some extra support.

Now, the amplifier is a must to boost those subwoofer frequencies, to bring the taste of actual bass using the car stereo system.

We already know how it's inside a car, there's not much space and you have to take that into consideration when you're adding some more equipment to the system.

The subwoofer is already compact to save some space, now stashing an extra amplifier alongside seems completely irrational in a situation like this.

That's why you should go with powered subwoofer. Despite being small, powered subwoofer still has some room for its built-in amplifier and that's everything. By purchasing this, you get an amplifier and don't even need to sacrifice some space for it, a complete win-win deal.

Filters

As we said earlier, the frequency range for bass is huge. However, not every frequency is worth it. Some frequencies are below human ear's hearing range and they do nothing better but causing unwanted distortion.

Filters are here to save the day. Subsonic filter, low-pass and high-pass filter, you name it! These filters block unnecessary frequencies from causing disturbance and thus help to produce quality bass.

Mounting and Wiring

Very vital stuff right there! When you're checking out a subwoofer, don't forget to take a look at the arrangement it holds for installation.

The mounting can get a bit complicated with the choice of location, but won't occur as a big deal if the subwoofer comes prepared for all the circumstances.

Enclosure

The materials, the design - everything related to the enclosure has a great impact on the subwoofer's output. The bass response depends on the structure a lot that one can imagine.

The response automatically gets deeper when the enclosure is sealed.

Moreover, the room it has for air transition plays a big role in the subwoofer's performance. The outcome of the same signal can be different due to the pace of air flowing inside.

The subwoofer needs to be protected both internally and externally. The materials used in manufacturing tells a lot about the arrangement it holds for protection.

User Reviews

Sounds crazy, but the benefits are incomparable. Since there are loads of suggestions to choose from, you can always turn to user reviews for some further assistance.

You'll be able to decide better whether the subwoofer will be good for you or not from their statements. Since users state their experience with the product, this will make it easier for you to understand its features and make the right choice.

Take the tips above under consideration, hopefully taking a decision won't be much of a problem anymore.

Conclusion

Here in the end! We hope you're satisfied with everything. We put everything you need to know about your purchase in one place to help you make a better decision.

All the possible questions you can have regarding the under-seat subwoofer, have been answered above. We tested and picked only the best under seat subwoofers. And in case you get confused because of all the suggestions, we thought it'd be better to help you out with some tips.
