For most of us, movies, music, and video games don’t reach their max potential unless the audio quality delivers good bass. That’s where an additional subwoofer plays a significant role. 

However, it’s quite difficult finding a high-grade subwoofer without breaking the bank account. We believe subwoofers under $400 are that happy-medium between top-shelf bass quality and a more reasonable price range. 

For whichever reason you’re searching for a subwoofer under $400, you’ve come to the right place. We formulated a list of the 6 highest-rated choices on the market. 

In Short, Here Are The Best Subwoofers Below $400

• Polk Audio HTS 10
• Definitive Technology ProSub 800
• Klipsch R-120SW
• Cambridge Audio Minx X201
• Klipsch R-100SW

1. Polk Audio HTS 10

First up, the Polk Audio HTS 10 is an excellent subwoofer running below $400. In addition to our full endorsement of this subwoofer, you’ll be pleased by its near-flawless reviews amongst customers, as well.

This subwoofer provides a spacious 10-inch woofer. In addition, the integrated 200 Watt amplifier delivers enormous bass that’s crisp and free from distortion. You’ll also love its modern appearance that enhances your room’s visual appeal. 

Users Say: “I bought this sub because my 10+-year-old 12 inch Polk audio sub started popping. Guessing the amp was on its way out. This 10-inch sub sounds tighter and cleaner than my 12 did. I’m super happy with it. I am very picky about my sound quality and this does a great job with music and movies. I have it paired with a Denon receiver and definitive surrounds. For anyone looking for good bass sound quality at a good price point, this is it.”

Tech Specs & Details

• 200 Watts
• 10-Inch Driver
• Patented Power Port Technology

2. Definitive Technology ProSub 800

Coming in barely below $400, the Definitive Technology ProSub 800 is an exceptional choice. This subwoofer produces an extra 100 Watts than the previous choice giving you a 300 Watt total. Furthermore, it also possesses a useful volume knob on the top right side. 

In case you need a subwoofer for a home theater, they recommend you incorporate it with ProMonitor 800 speakers and a ProCenter 100 center channel. 

Something you might find unusual but super beneficial is the compact size of only 15.8 inches tall, 10.4 inches wide, and 13 inches deep. Nonetheless, the beneficial part is how it generates are far greater sound that’s distortion-free for the small size. 

Users Say: “I bought this a few months ago. The bass is deep and rich, not distorted at all, even at louder volumes It was superior to my existing powered subwoofer and I liked it so much that I bought a second one the following week. I don’t want to sound like a cheerleader, but this is just what you want for your AVR system.”

• Sizes: 15.8 x 10.4 x 12.9
• 300 Watts
• 110 volts
• 8-Inch
• Frequency Response: 20Hz – 150Hz

3. Klipsch R-120SW

For good reasons, the Klipsch R-120SW is the most famous and absolute highest-rated on this list. Put plainly, we believe it provides the best sound quality of any subwoofer under $400. However, there are a plethora of reasons why we adore it.

For one, it has an attractive design that’ll boost the aesthetic value of your home. The appearance is modern, rich, and matches just about any room. 

In terms of how it gets the superb audio fidelity and stunning bass, there are a few technical aspects worth mentioning. It produces the highest wattage power of any subwoofer on this list 400 Watts. Moreover, the acoustic output is 116dB, it’s constructed of 12-inch high-excursion spun copper, and has an integrated digital amplifier. 

Recently, this subwoofer had a hefty price cut of 24% off the original amount. Although we’re unsure if this discount is permanent or temporary, we believe it’s, either way, an incredible bang for the buck. It’s our most recommended on this list!

Users Say: “Even though I’ve owned Klipsch products for years, I am still impressed with the incredible sounds this thing puts out. It is a perfect compliment to my R-28PF’s. Well packaged and easy to setup. If you appreciate pure and exact sound when listening to music or watching tv/movies, I highly recommend this product!”

Tech Specs & Details

• Sizes: 19.2 x 14 x 16.5 
• Weight: 31 pounds
• 400 Watts
• Acoustic Output: 116dB
• 29 hertz – 120 hertz

4. Cambridge Audio Minx X201

Here is yet another fabulous subwoofer with a futuristic sleek design. Running under $400, the Cambridge Audio Minx X201 produces a thunderous bass sound that’s clean, rich, and deep. 

One of its most prominent features is its petite size. While we were raving about one of the previous woofers for not taking up too much space, this one is significantly smaller at only 8.7 x 8.3 x 8.6 inches. You can even snugly fit it in a bookshelf. 

While its miniature construction is abnormally convenient for a subwoofer, the downside is it has a bit of trouble with the lower register frequency around 60Hz. Most people don’t notice it. However, if you’re an audiophile that’s very particular about the low-end, we recommend one of the Klipsch subwoofers. 

Users Say: “I’ve always wanted to check out the Cambridge stuff… This little sub seemed like a “punk” when compared around, but I needed something little for my desktop. I hooked this sub up with a couple of KEF Eggs for my desktop system. WHOA. Amazing is the word.”

Tech Specs & Details

• Sizes: 8.7 x 8.3 x 8.6
• Weight: 11 pounds
• 200 Watt 

5. Klipsch R-100SW

Like the previous Klipsch on this list, this one is essentially identical with a few differences to consider. The Klipsch R-100SW is nearly $110 cheaper with about 100 Watts fewer delivering a 300 peak Wattage. 

When it’s all said and done, if you need the absolute best sounding and most trustworthy subwoofer with no more than 300 Watts, this one is your best bet. But if you want over 300 Watts, you’re better off with the previous Klipsch. 

Currently, this subwoofer is also on a 32% reduction in price making it an even better value. It’s running well below $400 but certainly over performs the price by a vast margin.

Users Say: “I only thought I had a nice sub before this. This pumps out super tight and clean bass you can feel. This will rattle some tin signs I have on a wall two rooms away. Also, it is a work of art to look at! I have it paired with a set of Klipsch R-15PM monitors and it is a perfect, simple 2.1 setup for the TV.”

Tech Specs & Details

• Sizes: 14 5″ x 12 5″ x 16 4″
• Weight: 26 Pounds
• Frequency response: 32Hz – 120Hz
• 300 Watts

6. Skar Audio Single 15″

Last but not least, the Skar Audio Single 15″ is the most inexpensive option on this list. However, we believe it’s of the top 6 best subwoofers under $400. It has an outstanding bass response, build quality, and it’s well-received amongst users!

Users Say: “Got this for my girlfriend for her birthday. Pushing it with a cheap SSL 2000w amp (500w RMS) and the Audio Controls line output converter and it performs WAY BETTER than either of us expected.“

Tech Specs & Details

• Weight: 75.6 Pounds
• Peak Power: 1,200 Watts
• 15-Inch Speaker

• 2 Ohm

9 Best TV Soundbars With A Subwoofer?

What’s the best TV soundbar with a subwoofer for deep bass? For those looking to boost your TV audio dramatically, you’ve come to the right place. Anyone with a soundbar will substantially increase the overall sound quality of your favorite tv shows, movies, and video games. However, you can Bluetooth stream music with most of them, as well.

Most built-in speakers in recent TVs have gotten slightly worse over time. This is due to the thinner and larger TV screens don’t have enough room for speakers on the front. However, most newer TVs have drastically increased their visual quality. To get the best of both worlds, adding a soundbar will be a fantastic investment.

But why only listen to 2/3rds of the audio spectrum with a bass lacking soundbar? That’s where the added subwoofer with the soundbar comes in! After extensive research and testing, we formulated a list of the nine best TV soundbars with a subwoofer on the market.

1. VIZIO SB3821-C6

Not only do we recommend it, but it’s highly rated and customer-reviewed, as well.

Synchs to the TV ARC system so I don’t even need the remote. I can control volume for the whole set up with a fire tv 4K stick remote!”

Nevertheless, throughout the years I purchased many excellent systems. Today older and wiser I thought that I settling for lower standards when I purchased this Sony Sound Bar. To my complete surprise, this simple to install system sounded as good or better than the most expensive and complicated system I’ve ever had.

It also has built-in Chromecast, WiFi, Bluetooth capabilities, and Airplay 2. The last impressive feature worth mentioning is its virtual surround sound. 

I noticed a few downsides with this soundbar. For one, it’s slightly difficult to set up. That issue can be resolved by paying $76 more on expert installation on Amazon. Also, depending on what movie your watching, the sound can jump up and down on volume too quickly. In other words, words can be a bit too low in volume, while an explosion is a bit too loud. But Overall, the JBL Bar 5.1 is a great value soundbar running below $400. Be sure to check out the reviews below.

Not loud enough to shred the speakers but more than any adult could want. My only complaint is it is supposed to switch itself off and on with the TV. Mine only switches off and I have to restart it every time. there is a setting to change but it is NOT in the instruction manual. It was in the setup sheet that got tossed after I set it up. I could probably find the instruction online but most of the time I just use the TV sound so no big deal.”

Tech Specs & Details

• S-Force Pro virtual surround sound
• 7 Sound modes
• Voice improvement capabilities

8. Samsung 3.1 HW-R650

Users Say: “This sub-woofer and soundbar pairing works very well in my master bedroom. I’m not sure if they would work as well in a large living room but I can tell you without a doubt that they work fantastic in a 24′ x 30′ bedroom space. Maybe you can figure out the size of your room based on that and determine whether or not you’d like to move forward. The sound is very clean, the bass is plenty. Don’t expect this product’s base to shake the paint off your walls. For what it is supposed to do, it does it. If you want more, you’re going to need to move more air and get a much bigger sub-woofer. But for movies at night, very good.”

The surround-sound mode produces a dramatic 3D effect with much louder volumes; it’s impressive and fun after getting used to it. Slim design fits nicely under most bigger TVs. Would have liked to see a ‘night mode’ effect for compressing levels to allow listening to lower volumes. Some TVs can do that, but need to dig into the TV settings.”
