Kicking off our list is this behemoth of a subwoofer from Sundown Audio.   

If you thought that a Sundown 8-inch subwoofer was big, wait until you get a look at this bad boy. And, because this is an 18-inch subwoofer, it should go without saying that this is not for the faint-hearted.   

But hey, this is what you came here for, right?  

Equipped with a 3-inch aluminum with 2-ohm dual configuration voice coil that has a sensitivity of 92.3db, as well as aluminum vent spacers, the U-18 D2 has an RMS power rating of 1500W that’s guaranteed to shake the ground whenever the bass drops. But, of course, you’ll have to install this subwoofer in its recommended enclosure first. Otherwise, you’ll experience clarity and distortion issues.

When installed right, you can see why Sundown took an entire year to develop and customize the Sundown Audio U-18 D2.  

Speaking of custom, this 18-inch subwoofer has a lot of custom parts. This includes the cone body, as well as the surrounding material. This is custom construction is what separates it from other subwoofers of its size and why it’s widely considered the best in its class.   

Again, this subwoofer isn’t for every. However, if you’re not the type to settle for anything less than the best, then this is for you.  

Technical Features: 

  • Size: 18 inches 
  • Sensitivity: 92.3 
  • Power Handling: 2500 Watts (Peak) / 1500 Watts (RMS) 
  • Frequency Response: N/A 
  • Depth: 10.11 inches 
  • Impedance: Dual 2 Ohm  

PROS

  • Reasonably priced for an 18-inch subwoofer 
  • Premium construction with customized parts 
  • Superb sound quality 

CONS

  • Requires proper enclosure and installation to work, but this is pretty much expected for any other 18-inch subwoofer 

The Sundown Audio NS-15 V.3 D2, otherwise simply known as the Nightshade V3, is what you’d get if you packed an RMS power rating of 2500W (with a 5,000W peak) inside a 15-inch body made out of the highest-quality materials available and proudly made in the United States of America.

And oh, did we already mentioned that this beauty is handcrafted to perfection?

As part of the Nightshade line of products, these subwoofers have a reputation to live up to. But, this particular model doesn’t just meet expectations. It more than exceeds them. This makes it the ideal choice for music enthusiasts who can’t just have enough power.

NS-15 V.3 D2 15 Inch Subwoofer

Don’t worry. This isn’t just some powerful subwoofer made out of materials that can’t keep up.

A good example of the quality of the materials used for this subwoofer are the 3-inch aluminum voice coils for the heavily vented magnetic gap, as well as a high-temperature 4-layer aluminum flat wire voice coil to allow for prolonged use with minimal distortion. Also, you can use this subwoofer at either a 1-ohm parallel or a 4 ohms series because it uses dual 2-ohm coils.

The only big downside here is that this subwoofer is that it is power hungry, so you’ll have to upgrade both the alternator and battery of your automobile to keep up.

Technical Features:

  • Size: 15 inches
  • Sensitivity: 84.27dB
  • Power Handling: 5000 Watts (Peak) / 2500 Watts (RMS)
  • Frequency Response: 21-100Hz
  • Depth: 13 inches
  • Impedance: Dual 2 Ohm 

PROS

  • Handcrafted to guarantee optimal performance 
  • Excellent use of premium materials
  • 5000W peak power

CONS

  • Expensive

For something more reasonable in terms of size and price, the Sundown Audio SA-12 D2 REV.3 is something that even the average car owner would appreciate and won’t mind investing in.

With an RMS power rating of 750 watts, this 12-inch subwoofer won’t leave even enthusiasts wanting more. But, as expected of a Sundown Audio subwoofer, you also get so much more than just a reasonable power rating.

In addition to the amount of power that this subwoofer can drive, it’s also well-constructed.

The paper cone, for example, is made out of tough SPL competition-grade material. It also has anodized aluminum 2.5-inch voice coils. Also, users have the freedom to mount the subwoofer inside of sealed enclosures, or ported enclosures. This means that you can choose however you want to get your bass.

Because this subwoofer uses dual voice coils for an impedance of 2 ohms, you can use wire it in 1 ohm in parallel or 4 ohms in series. Additionally, you can also purchase the 4-ohm version of this subwoofer. You can then wire that subwoofer to 2 ohms in parallel or 8 ohms in series, depending on your preferences.

With a 2-year warranty included on top, the only thing you’ll be worrying about with this 12-inch car subwoofer is being pulled over by cops and paying for it. 

Technical Features:

  • Size: 12 inches
  • Sensitivity: 83.21
  • Power Handling: 750 Watts (RMS)
  • Frequency Response: N/A
  • Depth: 6.5 inches
  • Impedance: Dual 2 Ohm

PROS

  • Backed by an extensive 2-year warranty
  • Made out of competition-grade materials
  • Can be mounted on both sealed and ported enclosures

CONS

  • You’ll need a powerful amplifier to pair with this subwoofer

Power and value in a relatively small 8-inch package is nothing to scoff at, and this Sundown 8 inch sub definitely delivers.

What makes these 8-inch subwoofers so good isn’t necessarily the sound quality. Make no mistake, it does sound good. It features some serious rumble that you’ll easily mistake for something bigger.

You also won’t have to worry about your amplifier not being able to keep up with this subwoofer.

But, the issue here is that, because of the higher impedance compared to others in its class, this 8-inch subwoofer has a tendency to run hot at full power.

This isn’t necessarily a problem since you won’t be pumping up the volume all of the time. However, it’s still worth mentioning.

If you can look past that, you’ll get a high-quality 8-inch subwoofer that features the Sundown Audio stamp of approval. Not to mention, it’s made out of high-quality materials, with a drive motor mechanism and voice coils that should withstand years upon years of use if not downright abuse. 

Technical Features:

  • Size: 8 inches
  • Sensitivity: 81.4dB
  • Power Handling: 300 Watts (RMS)
  • Frequency Response: N/A
  • Depth: 5.25 inches
  • Impedance: Dual 2 Ohm

PROS

  • Elite performance for an entry-level subwoofer
  • Compact design is perfect limited spaces
  • Sounds larger than its size

CONS

  • Has a tendency to get hot quickly at full power

It’s common knowledge that the louder the volume, the more sound distortion there will be. However, that’s where the Sundown Audio X-6.5SW V.2 stands out.

Designed specifically to maintain sound quality across multiple volume levels, as well as frequencies, this subwoofer will let you enjoy a crisp and clear loud sound on your daily drive. Mind you, loud doesn’t even begin to describe just exactly the kind of volume that this 6.5-inch subwoofer is capable of.

This dual 2-ohm Sundown 6.5 subwoofer has a 300W RMS power rating, which, when installed in the manufacturer’s recommended sealed enclosure specifications, will be capable of even more.

More importantly, because of its high-quality build, as expected of a Sundown Audio product, you won’t have any worries maxing out this subwoofer.

If you’re looking for elite-level performance at an affordable price point in a reasonably-sized package, look no further than this 6.5-inch sub.

Technical Features:

  • Size: 6.5 inches
  • Sensitivity: N/A
  • Power Handling: 300 Watts (RMS)
  • Frequency Response: N/A
  • Depth: 4 inches
  • Impedance: Dual 2 Ohm
