Our Take on The Best 15 Inch Subwoofer

Table of Contents

When it comes to subwoofers, size really does matter. If you’re seeking big bass and have plenty of room in your vehicle, there’s no substitute for larger subs.

Otherwise, if space is an issue in your vehicle, and you still want to experience some bass, there are plenty of options out there including, smaller subs (8″ inches, 10″ inches,…), powered subwoofers. These space-saving bass systems can certainly make bass, but the larger subs’ deep bass’s quality and quantity are considerably better. If well-chosen and well placed, a large sub will deliver deep pounding bass that you can feel as much as you hear.

There are many 15-inch subs on the market, and some of them are virtually worthless, so you should definitely make sure you do your research before you decide on the one you buy. Luckily, we’ve put together a little guide to help you make the best 15-inch subwoofer decision. Enjoy!

We’ll go ahead and start this review with possibly one of the most badass, crazy, and all-powerful 15″ inch subwoofers on the market. ORION HCCA-152.

And, assuming you’ve got the cash to throw around, it’s one of the most hardcore subwoofers Orion® has ever made, bar none. Buying one of these subs will make everyone with small subs in their trunk jealous and make your pride of your sound system.

These subs are highly recommended for bassheads seeking more bass than what smaller subs can deliver. However, there are a few things you need to be aware of before purchasing a sub of this greatness.

ORION HCCA-154 review

First of all, as this sub is very power-hungry, you’ll certainly need to upgrade your electrical system; by that, we mean a big and powerful alternator, as well as at least an extra battery. That being said, you’ll also need an external amplifier with superior high-power output to feed this beast.

Additionally, you’ll have to build a customized box to accommodate it. Subs of this magnitude should be mounted facing up as they can rip apart what’s facing the box.

Orion® is a brand we haven’t come across very much at all, but we were quite pleasantly overwhelmed when we did.

Although this product’s price tag is fairly steep, it provides excellent performance, and if you’re here, that is important to you. Buying one of these subs will shake the hell out of everything and everyone around you. Your neighbors will want you to move. It’s just a whole different experience.

This particular subwoofer will set you back around $400. However, it’s one of the top 15″ subwoofers in the market. Not only is this sub built to last, but it is also outstanding in terms of performance – the results will blow your mind.

Clearly, due to the price tag and quality of this 15″ inch sub, I’d recommend it only to someone who thoroughly enjoys big bass and has the funds to support it. It would not be wise to splurge up to 400+ on top of line 15″ inch subwoofer if you are starting.

Rockford Fosgate P3D2-15

Those of you who read the last review and thought, “this sub is very demanding, technically and financially,” will be happy to give this bad boy a try.

We have reviewed several Rockford Fosgate products on this site before, and the story hasn’t changed.

Rockford Fosgate offers reasonably priced products. If you want to keep your sub-investment set under $200, we can’t think of a better option for a 15″ inch subwoofer than the P3D2-15.

Rockford Fosgate P3D2-15 review

The linked-to above Punch series subwoofer is designed for deeper, louder bass – resulting in an impressive sound that’ll shine out in a crowd.

Rockford Fosgate has built the P3D2-15 15″ subwoofer to stay rigid in high demanding sound pressure levels conditions and heavy play while staying light and responsive.

To make this sub deliver even bigger bass, RF used a new technique that consists of attaching the oversized rubber surrounding the cone, increasing available cone area by 25% – resulting in more air flow and eventually deeper bass.

For optimal results, Rockford Fosgate has incorporated a special venting to cool down the voice coils.

Additionally, the aluminum cone serves the purpose of a heat sink, dissipating heat away from the copper-clad aluminum voice coils so that you can experience incredibly consistent bass on an ongoing basis.

Power Acoustik MOFO-154X

We have not reviewed Power Acoustik products here before, but that’s not because we aren’t fond of them. On the contrary, this is a decent brand, offering a wide range of products, including subs, amps, tweeters, and a few speakers.

The brand is not the best and not the worst. However, their products are above average in almost everything starting from build quality, performance, bass output, and reasonable price tags. So I would have to say, overall, it’s an excellent deal for what it’s worth.

The MOFO-154X is a monster; it can deliver some ground-shaking bass. This is a great budget-friendly option for anyone craving big bass and wants to crank it up in the car without breaking that bank.

The 12″ inch model is rated at 1500 RMS power, while the 15″ inch model is rated at 1700 watts RMS. As you can notice, it’s a general rule that the bigger the woofer, the more power required.

VM Audio EXW15 Elux

This subwoofer is by far the least expensive of all 15″ inch subs we’ve reviewed in this lineup by far, but don’t let that fool you.

This subwoofer can handle up to 1300 watts of RMS power. It features a high excursion linear mechanical suspension system and a 4-ohm dual voice coil configuration, which allows a variety of wiring possibilities.

This subwoofer is built with stress-resistant materials, including a wide durable rubber surround, vibraducer feather-light IMPP for the cone; it also comes with a heavy-duty stamped steel basket with a high impact-resistant one-piece magnetic cover.

The EXW15 sub also features a direct voice coil surface-cooling system, some nice push terminals, and a motor cover on the backside.

The cover isn’t simply magnetized to the motor, usually the case with low-end woofers. Still, it’s securely adhered to the motor structure, adding a layer of protection to both the motor and the magnets.

Overall, this is a solid 15″ inch subwoofer for a competitive price. And it should last you for years if it is powered properly.

Do 15 Inch Subwoofers Sound Good?

The 15-inch subwoofer produces a satisfying bass, though “better” is, of course, subjective. Smaller subwoofers will provide a more crystalline and crisp sound, while bigger subwoofers, such as 15 inches in diameter, will produce a more precise and powerful sound.

Which 15-Inch Subwoofer Delivers the Most Powerful Bass?

The Rockford Fosgate P3D4-15 Punch produces the best 15-inch subwoofer bass. The P3D4 subwoofer is a high-end model meticulously crafted to provide excellent audio and last a long time. This subwoofer’s capacity to produce deep, high-quality bass notes and endure substantial force has made it a popular and preferable choice.

What Should I Look for In A 15-Inch Subwoofer?

You should look for a subwoofer that features aluminum voice coils. These coils are more durable than their copper counterparts. Also, keep in mind the maximum power ratings. As the number rises, the subwoofer’s full volume increases.

Are Bigger Subwoofers Better?

It’s best to go with a big, powerful subwoofer. A large sub is preferable to a smaller sub. Multiple subwoofers placed strategically throughout the room or corners provide superior and more natural sound than a single sub. In addition, bigger subwoofers produce more powerful bass.

How Much Wattage Does A 15-Inch Subwoofer Feature?

It has a 3200-watt RMS power output and a 15-inch woofer with a dual 4-ohm voice coil configuration (2 Subwoofers). The average power output is 800 watts per speaker, with a maximum of 1600 watts per channel.

Which 15-Inch Subwoofer Is Best for My Car?

The Gravity 15 Inch 3200 Watt Car Audio Subwoofer w/ 4 Ohm Power is an excellent option for your car. The music and sound quality it generates are superb. If you’re a serious music fan or audiophile, upgrading your car’s speakers could be a good investment.

What Should I Use to Tidy Up My Subwoofers?

You can use a damp microfiber cloth for a gentle wipe-down to remove oily residues like fingerprints. Use clean water or a mild cleanser without ammonia to wet the fabric. To clean, never use anything with alcohol, ammonia, bleach, or abrasives.

How Can I Make The 15-Inch Subwoofer Sound Clean?

You can make the 15-inch subwoofer sound clean by doing the following:

  • Eliminate the distortion
  • Reduce the amplitude of the signal
  • Level the bass and set the low-pass filter on the subwoofer
  • Make changes to the subwoofer and bass boost
  • Match the subwoofer volume to the central system’s volume

Can A Subwoofer Get Damaged By Dust?

Dust won’t damage your subwoofer in certain conditions. As long as the dust isn’t too thick, there shouldn’t be too much of a problem. As you know, breathing in dust is unhealthy for you, and as subwoofers move air, they also move dust. Therefore, a dust-free environment is preferable.
