Update – January 2022

[We have added a new 8-Inch Subwoofer brand at #9 to make this list more exhaustive and current for our readers.]

9 leading subwoofer brands, 12 hours and a lot of careful analysis led us to the conclusion that the BOSS Audio Systems CXX8 8 Inch Car Subwoofer is the best 8-inch subwoofer out there. It comes with the powerful 3-year platinum warranty supported by unbeatable brand legacy.

Only about 30 dollars can also lead you to a pretty decent Planet Audio AC8D 1200 Watt, 8 Inch, Dual 4 Ohm Voice Coil Car Subwoofer for the time being. At this price, it is hard to believe the incredible performance that it delivers but it will definitely prove to be worth your time and money.

So woofers and subwoofers, what’s the difference exactly? Well, not much but if we are getting all technical then just know that subwoofer is used to boost the frequency band below the 30 Hz level. On the other hand, the woofers deal with the frequencies above this level.

Factors To Consider Before Buying

Your vehicle deserves the best sound system and a good level of research in the same vein on your part.

Ground Zero Concerns

Here, we have made this tiring job vastly simpler for you and put together the main factors you need to consider when you are in the market for a brand new subwoofer.

Type of Enclosure

The type of enclosure you use for the subwoofer greatly affects the voice amplification process. Place it within a sealed box to get the highest level of bass boost. Go for the bandpass or ported enclosures when you want to increase the volume level noticeably.

Voice Coil Count

Subwoofers with a single coil are pretty common. But you get a good boost in the overall audio system handling with the help of dual coil variant. This version contains two completely different loops that are connected separately and mounted over a cylinder.

Range of Frequency

This is one of the most important factors that you need to pay attention to. This range will give you an idea of how well the subwoofer in question can reproduce the bass for the low frequencies. Take into account the lower limit of this range that will give you a clear idea of the lowest frequency range that it can capture and reproduce the bass for.

Sensitivity

It decides the power consumption that will be required to produce a certain level of sound. Just pick two random subwoofers with different power ratings. The sound produced by the subwoofer with lower sensitivity can easily be matched with a far lower power consumption with a subwoofer that has higher sensitivity.

Power Rating

The RMS power rating and the Peak power rating of a subwoofer will give you a pretty clear idea of how powerful a bass can it produce. Also, match the power output value of the amplifier with the power handling of the subwoofer to make sure that the final audio system that you put together for your car is perfectly in sync.

These are the select few factors that can make or break your car audio system depending upon how attentive you are towards their details during the purchase.

Price Tip

You need to buy smart to actually have a decent budget-luxury balance in your life. Read on to know when and where to splurge:

$150 and above

Under $50

You are in luck here since the competitive market scenario has finally worked out in your favor. The next level affordable 8-inch subwoofers can be bought from so many different reliable brands. You can get one for as low as 25 dollars with 6 months warranty.

You can even get a much more expensive refurbished subwoofer within this price range too. It can be a solid deal with proper verification of the product and the seller.

These are the key price points of 8-inch subwoofers in the market at the moment.

Subwoofer Surround Material Used

A fine quality material is used inside the cone of a subwoofer. This helps to keep the cone in place at all times to give a silky-smooth musical experience. The main job if this material wrap is to neither absorb nor distort the vibrations coming from the device. It is required to be durable and flexible for this role. Following are the three main materials popularly used for this purpose:

Santoprene

The best material to be used in the vehicle subwoofers. It is known for being highly resistant to the weather fluctuations. Also, it comes with remarkable durability. This high-end material will be the perfect protection for the subwoofers in your vehicle or anywhere else. And you will be tension-free regarding the safety of your devices.

Urethane

You go with this when you can’t afford to splurge but you are also looking from something at least semi-decent. The foam might not be just cutting it for your subwoofer here.

And it is better to upgrade then buy a whole new one. It is still very durable and malleable without breaking the bank. You can count on it to offer a protective shell to the subwoofer even in trying conditions.

Foam

The most affordable and commonly available of all three has to be the foam. They don’t need a lot of investment and you can replace them as easily when you think its time. This is why it is also popular among the manufacturers.

It makes it easy for them in the cost front and hence they can offer a more competitive pricing in the marketplace. This material is good enough to do its job of shielding the grounding the subwoofer cone, enough for this price range.

These are the three main materials being used in the 8-inch subwoofer category as of now.

Type of Basket in the Subwoofer Structure

The basket, also known as the web or the harness, is use to keep the coils and cone in place. This component helps in maintaining the overall structural integrity of the subwoofer. The three main types of baskets here are Hybrid, Cast and Stamped. Keep reading to know aa about them below:

Hybrid

Currently, the hybrid basket is leading this race in terms of utility. As the name suggests, they are mix of the best features of the stamped and the cast baskets. It demonstrated exceptional heat resistance just like the cast baskets.

And is known to be extremely tough similar to the stamped basket. Their popularity may also stem from them being actually very lightweight. They keep everything in place without adding to the baggage of your vehicle and hence your journeys. They are the ultimate choice here.

Cast

High performance requires steady performance consistently. And that is where the cast baskets shine. They are better geometry and bigger windows that helps with letting out the back-wave more seamlessly. Usually, you will not require the magnets to the warped here since they are much stiffer in their design.

The heat dissipation here is excellent that allows you to use it non-stop for hours on end even in the worst of summers. The adds to the lifespan of your subwoofer too thus acting as an added insurance for your purchase. A lot of premium subwoofer brands trust the cast basket for their innovations.

Stamped

The stamp basket is quite affordable for the manufacturers to add into the device. This makes a significance dent in the pricing of the subwoofer. They are the most rigid of all three hence they offer a solid support to the subwoofer from within even in case of a heavy-handed use.

A variety of sounds and vibrations can resonate with this basket. They maintain the structure through and through for years to come without needing expensive tools and servicing trips. You can easily DIY them too with little experience without worrying too much about messing them up.

Personally, we think that the hybrid basket is most well-suited out of all three for the varied usage of your subwoofer in the following years.

Types of Subwoofers

The two main types of subwoofers you will have to choose from are as follows:

Passive Subwoofer

If you have a lot of room and time to explore then go with this one. It comes without an in-built amplifier. That means you need to buy one of those too now. But it also gives you a lot of room to tinker with the audio experience.

Passive Subwoofer

If you are really into the musical experience then you will definitely want to play the technology God with this option. You will need extra cables and knick-knacks too to keep things connected and in place while you invent new ways to get your money’s worth from your latest subwoofer.

Powered Subwoofer

This is what you buy when you live in a studio apartment in the big city and are on the move most of the time. You don’t have time to experiment because, well, you don’t want to. So, you get your in-built amplifier with this one that is calibrated, synced and set in all the other ways too it gives you that expected experience.

However, it might cost you a lot more than the passive one. And you lose out on the entire thing when it breaks down. There is not much to repurpose here. Also, the sound quality difference the two is not that much. Unless, you are a bit too particular about how your subwoofer chooses to breathe.

We vote for the powered subwoofer here. We have the interweb, we don’t need to go out of our way to choose complications with DIY subwoofers.

Types of Cone Material

The cone needs to be in place at all times to achieve distortion-free music. We need a material here that will help in amplifying and focusing the sound without compromising on the sturdiness of the cone.

Magnesium

The material is extremely cheap which translated directly to its pricing and popularity. You will be hard-pressed to find more economical options than this one. But it shows in the substandard quality of the pitch return and resonance.

You will find this in mostly the low to mid-range subwoofers. But its still worth a try if your subwoofer preferences are just experimenting and feeling lucky that day.

Carbon Fiber

It is light and cheap very easily available. But you will find it in a lot of low-end subwoofers. It is nice for a trip or a long weekend where you don’t care whether you return with your subwoofer or not.

We do need something that can use as the new disposable cameras! Or the return gifts when you have 1000 guests on the list. This can be that polite affordable gesture.

Polypropylene

This one is rigid and can outlast even the subwoofer itself. This one might not be dirt cheap but still within the medium pricing range. This material is known for its durability. However, you won’t find it in a lot of subwoofers because it alters the scape of the sound thus interfering with the audio precision. Not a lot of manufacturers use it in their products because of this reason.

Treated Paper

The cone constructions and the diaphragm use a lot of treated paper. Durable coatings are applied onto this woven paper that is know for being sufficiently flexible. It is most commonly used in this category of subwoofers. You will find them to be exceptionally lightweight too.

Kevlar

The best quality of cone material today has to be the Kevlar. It is use in a lot of expensive and quality subwoofers. This material has that desirable combo of being lightweight and durable. On top it that, it offers next level sound amplification. It is known for its reliability in both performance and durability.

Kevlar has to be obvious choice here for us.

Basic Handling Tips

Tuning

You need to separately tune all the components in connected with your subwoofer system. And then tune the subwoofer. Do this after the installation process to get best sound quality. This step is forgotten most of the time but you will notice massive difference when you try it with your next upgrade. Before you return or discard, give this tuning a try.

Separate Subwoofers

Well, its not as impractical as it sounds. If you listen to the same kind of music day and night and will continue to do so then fine. Otherwise, it just makes sense to get subwoofers that support different kind of music genres like techno, dance, hip-hop, jazz etc. Get a cheaper model if this sounds too opulent at first. And then see how you were doing life wrong all this while!

Upgrade the Car System

Next, we have the factory speakers in the car. They at best are going to be delightfully generic because they were made to be palatable for almost anyone that will be willing to buy that car that day. One of the best ways to make your car music seem more like your own is by replacing the car speakers with your preferred ones. This will add to the clarity and tight bass effect of your car system.

Car Music System

Enclosure

You can put the subwoofer in an enclosure made out of a sturdy box. It is not that uncommon to get one with your car or with the subwoofer if you do a deep-dive for one. But you can easily make one for yourself too. Fill this enclosure with polyester fibre and make sure it is sealed properly on all side. This will clear bass tone and lower unwanted resonance. Adjust the volume and you are good to go.

 Bigger Amplifier

The distortion tells you when and what to replace. If you like your music loud but it has been full of distortion since you bought it then you need a bigger amplifier. Distortion at higher volume signals to an amplifier that is just screeching after being forced beyond its caliber. So, turn down the amp’s gain of the sub and get a bigger subwoofer and amplifier combo.

Type of Enclosure

You wound thing it does not but the type of enclosure actually makes a very noticeable difference in the bass performance. For low and deep frequencies, you will be needing a subwoofer in a sealed box. Most of the time you will get a pre-mounted box. Bandpass and ported enclosure will enhance the volume range of your subwoofer. Try out different types of enclosures and tell us in the comments below about your wins and losses.

These tips and tricks can help you in making the right decision while getting your next favorite subwoofer.
