7 Best 15 Inch Subwoofers in 2022 – Reviews and Buying Guide (Bass In Your Face)

Whether you’re part of a jungle revival or you want to bring your hard rock to life, a subwoofer is the way to go.

Regular speakers, even component speakers, can’t effectively produce the lowest frequencies in our music – those from around 60 Hz (hertz) to 200 Hz. These rumbling frequencies are felt in our bones and they turn our car sound systems into a full-body experience.

And bass is best when it’s big. For the loudest bass, a 15-inch subwoofer is hard to beat. These beasts of bass displace more air than any smaller sub, and so produce the most earth-shattering bass around.

Most 15-inch subs come with great features that allow them to fit into smaller spaces in your vehicle so don’t be afraid of these sizeable subs. And they have other features that facilitate a perfect bass balance to bring out precise sound frequency in different tones.

With a 15-inch subwoofer, your speakers will exert a denser and more precise bass sound. But choosing the right sub for your system is about more than size. So let’s dive into the most excellent subwoofers on the market to help boost your surround sound.

So, what are your options in 2022?

2. Rockford Fosgate P3D2 – Best Looking

The P3D2 subwoofer offers grade-A performance among Rockford Fosgate’s models. They offer rich and tight bass and can withstand a heavy 600 watts of RMS power.

Rockford Fosgate P3D2-15 Punch P3 DVC 2 Ohm 15-Inch 600 Watts RMS 1200 Watts Peak Subwoofer
Pros
  • Tremendous strength
  • Minimal resonance and clean sound
  • Mounting patterns are flex-fit
  • Tear and fatigue resistant
Cons
  • Pretty expensive

Right off the bat, this sub looks incredible. Its sleek and powerful design deserves to be on display – and it will be because you can’t hide this bad boy under the seat!

This 15-inch subwoofer features an anodized aluminum cone and a dirt cap. The aluminum is lightweight and rigid to remove bend under higher performance, thus refining its bass.

This feature is complemented with a Rockford vertical attach surround technique. This increases the sub’s aluminum area by 25%.

It also includes a distinctive” spider vent” build that holds the cooler and basket to provide more power and reduce mass and reverberation. This feature expands the woofer’s lifespan and incidence response.

However, it has specifications for use, including sealed or vented enclosures and a mounting depth of 7.58 and 13.94 diameters.

The sub has temperature-resistant speech coils reinforced with a Nomex collar. Buying the system from authorized dealers comes with a one-year warranty.

3. Skar Audio VXF – Most Durable

The Skar audio VFX is the definitive SPL (sound pressure level) subwoofer that incorporates super low frequencies down to 31.4 Hz (hertz) while still playing a range of notes with precision.

Skar Audio VXF
Pros
  • 000 watts’ peak power and 1500 watts RMS
  • Advanced air cooling
  • Extended playtime
Cons
  • Expensive

1500 watts of RMS power mean you can pump out the bass all day long and 3000 watts of maximum power ensures this sub can handle any extreme power in the moment. The Skar VFX-15 is built to be played loud and long.

You’ll find quality materials in the subwoofer. The paper cone is competition grade and the 3-inch hi-temp voice coil built of copper hits every note and is exceptionally conductive while being powered by the 300oz ferrite motor.

The versatile subwoofer will work with a sealed or ported enclosure (with 2.75 cubic feet and 3.25 cubic feet respectively) – but for an optimum SPL, a ported enclosure is preferred to provide more air around the subwoofer. So you’ll need a good amount of space to install the sub.

And all that power requires a substantial amplifier to go along with it. Big sound is guaranteed from this subwoofer but be ready for spending big bucks to get it up and running.

But consider it an investment: this is a durable sub that can go the distance as it incorporates a four-layered spider with lead stitches under its thick foam settings.

Bottom Line If you need a system for your car, the 3000 power watts and the profound bass made by this system will “blow your mind”. View Latest Price on Amazon →

This woofer has a hefty 95 oz. magnet to enable louder volumes played accurately, and the 92dB (decibel) of sensitivity is at the upper end of the spectrum, further enabling loud volumes (with less power).

The 2.5” 4-layer dual voice coil is corrosion resistant and will have a long lifespan – and this sub is built for further durability by using a “special treated foam surround” to engineer the entire system. This fatigue-resistant design keeps it safe and fits anyone looking for a clean-cut woofer.

It is pretty easy to fix with a mounting depth of 6.3 inches, and unlike a lot of 15-inch subs, it is also compatible with most cars, boats, or recreational vehicles’ sound systems.

Bottom Line A great value subwoofer with dual subs and a relatively shallow mounting depth to ensure easy installation. View Latest Price on Amazon →

5. American Bass E1544 – Best Clearest Audio

This elite subwoofer from American Bass realizes exceptional power and accurate, reference-grade bass. There’s a decent 1200 watts of RMS power but a sightly reduced 2400-watts of peak power on this sub.

American Bass E1544
Pros
  • 1200 watts RMS, 2400-watt max power
  • 3-inch set of dual voice coils
  • Affordable yet powerful
Cons
  • Requires a heavy-gauge wire to get it down to 2-ohm impedance

This woofer features hefty twin 75-ounce magnet stacks that amplify the tone’s quality by strengthening the vibrations. It also offers pronounced versatility by offering impedance at either 2 or 4 ohms.

Theis Elite sub features a stamped aluminum basket – not quite as desirable as a cast basket, but American Bass has used this as a way to keep costs down and offer the sub at an affordable price. They haven’t compromised on a durable non-pressed paper cone, however, and it boasts the new chilling pump motorized design equipped with a rubber seal and magnetic boot for extra cooling.

Bottom Line American Bass has done a great job of balancing price and performance with this 15-inch subwoofer that provides exceptionally clear-sounding bass. View Latest Price on Amazon →

6. Skar Audio EVL – Best Performance

This subwoofer is a 15″ double 2-ohm that gives new meaning to the production concept of low-end sound. The ingenuity of this sub’s design is demonstrated in its audio eminence and performance.

Skar Audio EVL
Pros
  • 2500 watt max/1250 watts RMS’ power
  • Innovative airflow cooling mechanism
  • Spider suspension that gives it flexibility
Cons
  • Low sensitivity

It provides incredible bass because of the advanced engineering in its features. It boasts a 2500-watt (max) power, 1,250-watt RMS power, and a 20-250 hertz frequency response. But the power rating alone can’t speak to the sound and volume that this sub is capable of, thanks to competition-grade materials that elevate it on every level.

Additionally, its design incorporates an excellent roll form to generate highly responsive low-end sound. Its suspension design comprises Skar’s EVL series’s characteristic structure, a damper, and a double-layers spider linking the speech coil with premium lead wire stitches.

The lower sensitivity, at 86.2dB, means it will require relatively more power to produce the same loud bass as other models – but Skar’s innovative design has more than made up for this.

Bottom Line This incredible 15 inch subwoofer is an ideal choice for anyone looking for a high-performance sound system. It produces excellent sound and can work efficiently for long periods. View Latest Price on Amazon →

7. Rockville RVP15W8 – Best Budget Option

Rockville Raw Pro subwoofers give a high-quality boom on a budget – in fact, you get double the bang for your buck with this double sub setup.

IMAGE ATL TEXT
Pros
  • It’s durable when combined with a suitable enclosure and a reliable amplifier
  • Clear, loud audio system
  • Built to last
Cons
  • Limited power output

Power handling is 500 watts RMS per sub, or 1000 watts total. Compared to a lot of 15-inch subs around that’s pretty low, but it’s a fair compromise for such an affordable system.

New Rockville RVP15W8 comes with an ultra-stiff, fiber paper cone, which boosts the sound quality. It also has a paper-made dust cap that helps keep dust off to reduce sound interference and ensure optimum performance.

It comes with Conex spiders, keeping the voice coil centers and ensuring the subwoofer sounds great. And further, the interior is lined with Accordion cloth which helps shield the sub from strong internal waves.

Rockville takes sound quality seriously. This powerful 15″ subwoofer has undergone top-level quality control to prevent instances of sound compromise. The manufacturer has conducted extensive tests to ensure that it produces the best sound quality and bass for its users.

The lighter magnets at 51 oz and the 2.5-inch voice coil are evidence that Rockville has had to cut the specs somewhat to hit this price point – but shoppers on a budget who aren’t looking for premium performance will find this 15″ subwoofer a huge upgrade for their OEM (original equipment manufacturer) sound system.

Bottom Line Rockville Raw Pro RVP15W8 is an ideal subwoofer for anyone looking for excellent sound output on a budget. They’ve compromised in all the right places to produce an affordable sub that still bangs. View Latest Price on Amazon →

Before Your Buy: The Buyer’s Guide to 15 Inch Subwoofer

We’ve looked into the best 15-inch subwoofer on the market to help you make an informed decision. However, choosing the right sound system for your car can be complicated – from power output to installation, there’s a lot to consider.

When choosing a 15″ subwoofer, here are some essential things to look at:

Power Consumption

For most of us, the first thing we look at when we examine a subwoofer’s specs is the power consumption. All subwoofers will have two ratings for power: maximum or peak power, and RMS (root mean squared) power which refers to the amount of power they can tolerate continuously.

Don’t be fooled by impressive peak power ratings: RMS is the more important metric. This tells us how loud our sub can go consistently.

Even the lowest powered 15-inch subs on this list hit around 500 watts of RMS – enough to shake and rattle you and a neighboring vehicle. But if you like to go mad with power, aim for 1000 watts or beyond.

Active/Powered Subwoofers Or Passive Subwoofers?

Subwoofers, especially 15-inch subwoofers, have serious power demands: much more than your vehicle’s head unit can provide. That means they’ll need an amplifier to power them.

Active subwoofers, also known as powered subs, have an in-built amp perfectly matched to the specs of the sub. Passive subwoofers – like most on this list of the best 15-inch subwoofers – require an external amp.

Active subs are a great option if you’re concerned about installation or want to conserve space in a smaller vehicle, but often the amp that comes with them is a compromise on power and features a smaller driver. If you’re looking for 15-inch subwoofers to access bass at an extraordinary level, a passive subwoofer and external amp will provide the optimal system.

Enclosure

Subwoofers need to be boxed correctly to provide the optimal sound – that’s because they need a buffer of air around them to produce the powerful vibrations required for serious bass. Your choice of enclosure will be determined by the kind of sound you’re looking for as well as space requirements.

Enclosures can be sealed or ported (vented) to allow additional airflow, and if your sub doesn’t come with an enclosure be prepared to build or buy one yourself.

Driver Size

Size really does mean a lot when purchasing a subwoofer. That is because you have to extract significant amounts of air to produce the low frequencies.

The two ways in which air movement happens mainly rely on the surface area of the subwoofer’s drivers and the driver’s excursion (The distance the cone moves in and out).

Smaller subs try to expel the air using more excursion, but excessive excursion could result in audio distortion or non-linearities. Grander cones expel more air with ideal excursion levels, but their bigger surface area could cause the cone to blow out.

So, look for a good balance between the speaker’s size and its excursion when purchasing the subwoofer. Also, assess the subwoofer’s driver rankings because they will help you determine the size of the voice coil and the density of the magnet they come with.

Impedance

Impedance refers to the resistance the subwoofer puts up to the current flowing into it and it’s measured in ohms. A lower resistance makes it easier for an amplifier to provide power to the sub and tends to be better if you’re looking for loud volumes and powerful bass.

A lot of the subwoofers on our list have the lowest impedance at 2 ohms, but 4 ohm and 8-ohm impedance aren’t uncommon.

Premium Materials

Internal components of the subwoofer – including the voice coil and cones – as well as external elements like the basket, can all be built from a wide variety of materials that affect sound quality and durability.

Copper, or copper-covered aluminum, is the best choice for a voice coil while paper is common for cones, but anodized aluminum cones can sound great if they’re built right – by reputable brands like Rockford Fosgate, for example.

Low-Tone Extension Capabilities

Many subwoofers cannot produce heavy bass tones. In a technical aspect, this implies that they cannot reach frequencies at or below 20Hz (the lowest limit of human hearing).

Therefore, they try to compensate for it by aggrandizing the mid-bass capabilities to compensate for the missing frequencies. This way, it can produce a loud, unilateral frequency bass, creating an unbelievable audio experience that removes the feeling that the artist or producer wanted to give off in the low-tier frequencies.

Ideally, subs deliver the heavy-duty bass with the required clarity and intensity, and deep bass subwoofers create notes so heavy they can’t even be heard — only felt!

If you inspect the specifications sheet, it is paramount to understand that the numbers are curated based on test results from an anechoic room (that’s designed to absorb sound).

That way of testing has some prejudice for subs because they depend on sound reflections in the space to create suitable, strong frequencies. As such, a sub may only be described as reaching as low as 30Hz, but in reality, it goes much deeper.

Beware of subs that look like they can run out of power on heavy-duty bass notes. Put on your beloved EDM bass drop, as it will give you an insight into how the bass falls to lower frequencies, and the volume begins to go down as well, too.

Top-tier subs typically maintain their output levels all the way down.

Low-Tone Audio Output at High Sound Pressure Levels (SPLs)

That’s a mouthful for newbies, but the notion is quite essential. A top-tier sub works effortlessly, giving off loud and distortion-free sounds, no matter how heavy or demanding the audio material.

Unlike other sound systems, some subwoofers have their own inbuilt amps and DSP engines that allow them to make their automatic volume adjustments when a stereo system is set up.

Smaller subs use amp limiting, which helps reduce the volume of the largest instances of bass bursts to safeguard the amp from overworking. This effect results in the bass “disappearing” when you want it the most, like an action movie bomb explosion or an EDM bass drop.

Low-tone output at top-level SPLs is an essential feature designed to safeguard the sub from destroying the driver or amp while creating a deflating audio experience. A top-tier sub expels adequate energy to perform efficiently with high SPLs well past the reference volume, without sinking or simply absconding at those very vital moments.

Keenly listen to how much power and mind-blowing energy the subwoofer creates with the heaviest bass frequencies in your music.

If you fail to experience this in person, it’s advisable to talk to an attendant or technician who is well versed with subs. You can also assess the wattage because it lets you know how big the internal amp is.

Frequency Response Accuracy

Tone response refers to the measurement of the audio range and pitch. It covers the deeps and raises between different notes. High-quality subs give off the exact bass level you need to hear at the correct pitch with total truthfulness to the music, movie, or other audio source content.

Subs with Low-tone Responses Struggle When Outputting High-Tone Audio.

So, ask yourself, “Is the sound loud, clear, and strong like it is supposed to be?” “Or is it inaudible, flat notes that sound warped and unclear?” Bass should not be dull thuds but rather an extension of the sound your sound systems are producing.

Running Speed During Transients

Running speed is frequently termed the subwoofer’s ability to “start and stop instantly.” An ideal sub has a swift response or alterations in momentum (speeding and slowing down).

When such exchanges don’t happen at fast speeds, excess frequencies are created during those load times, and the sub is unable to keep up with your audio systems in an audibly impressive nature.

For this reason, inferior subs have a tough time keeping up with wide-range sound systems when superior bass lines, next-level action clips, and other full-range content are applied. The impact? A loss of great detail.

With smaller subs, the bass could take over the audio field in an unprecedented and unappealing way. World-class subwoofers stop producing bass at the exact moment they are supposed to and produce it at the ideal moment.

The audio is indistinguishable from the sound system sound production, and everything resonates in perfect unison.

How does the bass couple with the other sound systems?

Does it take over and control the sound in an aggressive but chaotic way? The transients are slow.

The sub should seem like a part of your sound systems, seamlessly blending with their sound and hastening the performance, not overwhelming it.

Blend Capability with Vast Spectrum Sound Systems

No one wants to only hear the bass in their car stereo sound system. A good subwoofer brings out a wholesome experience where the sub lays the sonic foundation but never draws attention to the bass alone or its location in the room.

Bass is all-directional, and a sub needs to pressurize and energize the space without overemphasizing the soundstage or exposing its location and presence in an unappealing way.

A top-tier subwoofer puts on a heavy and haptic audible element that can’t be missed but always sticks as complementary to the whole audio system as a whole.

Just like the preceding tip, be keen on how the bass fits in with other audio systems. The sub should sound like it’s part of the whole sound system, not taking over the entire show.

Do I Need An Amplifier For My 15-inch Subwoofer?

Most 15-inch subwoofers are passive – meaning they don’t have an in-built amplifier and require an external amp wired into the system. This is important to bear in mind when you’re finding space in your trunk for your sub, as well as when you think about the complexity of the wiring.

Your amplifier will also need to match the power of your chosen subwoofer. If you have a sub with 3000-watts peak power, choose an amplifier with a power output of over 3,000 watts (4,000 watts or more, to be safe) to ensure you don’t underpower your sub.

Can I Install My Own 15-inch Subwoofer?

Installing your own subwoofer is an achievable task for the budding car audio enthusiast and it’s a good way to get intimate with your sound system. Installing a subwoofer can be greatly simplified by choosing an enclosed, powered subwoofer and finding a branded wiring harness – but don’t be put off choosing a passive sub and finding a suitable amp if you have specific subwoofer requirements.

Find a space in your vehicle that’s dust-free and well ventilated and get to work installing your subwoofer!

Wrapping Up…

15-inches of earth-shattering bass might sound like overkill if you’re new to the aftermarket sound system game. And it’s true that 8-inch, 10-inch, and 12-inch subwoofers can sound great.

But if you like to turn it up, then bigger is better in the world of woofers. And it doesn’t get any bigger than a 15-inch subwoofer.

You can turn your trunk into a festival stage with any one of the 15-inch subwoofers on this list, and budget options like the New Rockville RVP15W8 prove that it can be done on a budget.

Size matters: a 15-inch subwoofer is going to put serious bass in your car, and bass in your face. Let’s get the party started…
