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.
