Best subwoofer 2023: Enjoy subterranean bass
Boost the low-end impact of your sound system with our pick of the best subwoofers for every budget
Nothing says blockbuster film like deep bass, and incorporating one of the best subwoofers into your home audio setup is the easiest way to achieve more impactful low-end frequencies.
The lower the frequencies generated, the more a system starts to feel like a genuine home cinema, and effectively integrated bass can also give music some much-needed low-end punch.
All speakers operate on the same basic principle of generating sound by physically moving air. The bigger the driver, the more air being shifted and the lower the frequencies. At the end of the day, there’s no replacement for displacement, so if you want more bass you need the best subwoofer you can afford.
There are a number of things to consider before buying a subwoofer, and you’ll find a comprehensive buying guide answering all of your burning questions located below our pick of the best subwoofers on the market today.

How we test the best subwoofers
A number of factors determine whether a subwoofer is any good or not, but the most important metric is how it sounds, so we spend a great deal of time testing audio quality. We expose the sub to a variety of different content, including films, music and video games, at varying volume levels, assessing its ability to reproduce low-end frequencies with power, accuracy and clarity.
We also try the subwoofer out in various positions around the room in which we’re testing as this has a noticeable impact on sonic performance. Subwoofers are tested using whichever connection methods they support, be they physical or wireless, and we assess how easy the sub is to incorporate into your current home audio system.
We also take time to evaluate the build quality of every subwoofer we look at, ensuring that any product that we recommend is well-constructed and fit for purpose. Finally, we’ll thoroughly explore any control options that may be available, with many subwoofers now compatible with companion apps that offer options such as volume control, cross-over points and bass correction.
The best subwoofers you can buy in 2023
1. SVS SB-1000 Pro: Best affordable subwoofer
Price when reviewed: £659 | Check price at AV.com
The SVS SB-1000 Pro is a fantastic entry-level subwoofer that not only delivers deep and powerful bass at an affordable price, but also includes a host of features usually only found on more expensive mid-range models.
The sealed enclosure is extremely well made, and somehow SVS has managed to cram a redesigned 12in high-excursion driver and upgraded amplification into what is basically a 13in cube. The result is bass performance that’s precise, tight, musical and controlled, with a surprising amount of extension considering the SB-1000 Pro’s diminutive proportions.
This smaller footprint makes installation easier and more discreet, plus it’s relatively flexible in terms of positioning. The inclusion of a smartphone app is also a major benefit, allowing you to set up, adjust, optimise and control the sub without ever leaving the sofa. The SB-1000 Pro offers great value, and you won’t find a better sub for movies, music and gaming at this price.
Key specs – Drivers: 1 x 12in; Enclosure: Sealed; Stated power: 325W RMS; Stated frequency response: 20-270Hz (+/-3dB); Remote control: SVS App; Dimensions (WDH): 330 x 375 x 342mm; Weight: 11.9kg; Finishes: Premium Black Ash, Piano Gloss Black, Gloss White
2. Sonos Sub (Gen 3): Best wireless subwoofer
Price when reviewed: £799 | Check price at Amazon
While many of the subwoofers in this guide offer an optional wireless module, the Sonos Sub (Gen 3) is designed purely to be used in a wireless system. Sonos is the master of wireless multiroom music, but the addition of this subwoofer shows the company is also serious about delivering impressive home cinema sound from systems composed of its various speakers.
The Sub (Gen 3) is fairly large, and although Sonos doesn’t mention the size of the drivers, they use a force-cancelling configuration to produce deeper bass. There are also dual acoustic ports for increased low-end extension, and a pair of Class D amplifiers (although once again the actual power rating isn’t given). However, Sonos does claim the Sub (Gen 3) goes down to 25Hz.
Regardless of the specs, the performance is impressive, with plenty of deep bass extension and responsive power. The Sub (Gen 3) sports a slimline cabinet, is easy to set up, flexible in terms of placement, and integrates seamlessly with other Sonos speakers. It also adds a dynamic, controlled and punchy low-end foundation to multichannel systems, providing depth and scale.
Key specs – Drivers: N/A; Enclosure: Ported; Stated power: N/A; Stated frequency response: Down to 25Hz; Remote control: Sonos App; Dimensions (WDH): 402 x 158 x 389mm; Weight: 16kg; Finishes: Matte Black, Matte White

6. Paradigm Defiance X12: Best high-end subwoofer
Price when reviewed: £1,949 | Check price at Touchstone AV
The Paradigm Defiance X12 is a genuinely excellent subwoofer that delivers exceptional performance at a surprisingly competitive price. The 12in driver with its patented ART surround generates bass with remarkable depth and composure.
The X12 manages the clever trick of retaining the speed and control of a sealed unit, while also benefiting from the low-end extension offered by its high-velocity low-turbulence ported design. The ensuing bass enjoys a nuanced and articulate delivery, while also managing to deliver plenty of enjoyable low-end impact.
The inclusion of a remote app and ARC room correction make for useful features you won’t find on competing subwoofers with more power and deeper frequency response. Setup and control are both easy thanks to this app, and ARC ensures that the bass is smooth and perfectly integrated with the rest of the system.
The design is simple and unassuming, the build quality is excellent and the overall package is very impressive. There’s even an optional wireless module to eliminate cables and keep installation tidy. Paradigm is often associated with very high-end speakers, but in the case of the Defiance X12 subwoofer, it’s taken the mid-range by storm.
Key specs – Drivers: 1 x 12in; Enclosure: Ported; Stated power: 650W RMS; Stated frequency response: 20-230Hz (+/-3dB); Remote control: Subwoofer Control App; Dimensions (WDH): 457 x 494 x 493mm; Weight: 28.1kg; Finishes: Satin Black
7. Sonos Sub Mini: Best value wireless subwoofer
Price when reviewed: £429 | Check price at Sonos
If you’re looking for a cheaper, more compact alternative to the Sonos Sub (gen 3), the Sub Mini is the wireless subwoofer for you.
Designed to provide the Sonos Ray and Beam 2 soundbars with some additional low-end oomph, the Sub Mini incorporates two “force-cancelling” 6in woofers backed by sealed chambers and powered by class-D amplifiers. This setup allows sound to reverberate within the body, neutralises distortion and extends the bass response all the way down to 25hz.
The regular Sub is better suited to larger rooms and remains the superior choice for those who own larger, more powerful Sonos devices like the Sonos Arc. But for those with small to medium sized listening environments, the Sonos Sub Mini is an exceptional device offering most of the same features as its bigger sibling for significantly less money.

8. MK X12+: Best subwoofer for home cinema
Price when reviewed: £4,295 | Check price at Quiet Interiors 
MK has done more to pioneer the concept of subwoofers in the home than just about any other manufacturer, and the X12+ is an upgraded version of its highly regarded THX Ultra-certified predecessor. This latest model employs a pair of newly developed 12in carbon fibre drivers in a push-pull architecture to reduce distortion and increase bass extension. Two Class D amps each deliver 600W RMS, ensuring the X12+ has power to spare as it dives the infrasonic depths.
The resulting subwoofer is seismic in terms of its low-end slam, but also surprisingly detailed and articulate in the process. This makes it ideal for handling today’s bass-heavy blockbuster soundtracks, and you won’t find a better subwoofer for giving movies depth and scale.
The design is fairly basic, with a simple matte finish, but given MK speakers and subwoofers are regularly used on mixing stages around the world, that’s not surprising. This is a no-nonsense THX-certified subwoofer that’s the choice of the professionals, making the X12+ perfect for any self-respecting movie fan.
Key specs – Drivers: 2 x 12in; Enclosure: Sealed; Stated power: 600W RMS; Stated frequency response: 18-200Hz (+/-3dB); Remote control: No; Dimensions (WDH): 450 x 385 x 728mm; Weight: 45.9kg; Finishes: Satin Black
How to choose the best subwoofer for you
What size speaker driver does my subwoofer need?
As mentioned in the introduction, the more air a driver can displace, the lower the frequencies it can generate. This means that when it comes to subwoofers, size does matter.
While the built-in amplification will play a role in the amount of energy a sub can produce, as a general rule of thumb, the bigger the driver the better. For deep bass you should be looking for a sub with a driver that is at least 10in, but you could consider a 12in or even larger woofer. Interestingly, a big driver doesn’t necessarily mean the subwoofer has to be huge, and there are a number of sealed units that manage to cram 12in drivers into surprisingly compact cabinets.
Does driver orientation matter for subwoofers?
How the driver is mounted will be a factor, with a choice of forward, downward or sideways. Since bass is non-directional, the design doesn’t actually make a massive difference to performance, but which is best for you will depend on where you want to position the subwoofer. If it’s at the front of the room and near your main speakers, then a forward-firing sub can be a good choice.
A side-firing sub can also work well at the front of the room, and depending on which side the driver is mounted, you could position it between one of the main left or right speakers and the centre speaker. However, you should avoid corners, especially if they’re located on the firing side.
There are subwoofers that employ two drivers firing to the left and right simultaneously, which use force-cancelling to generate increased output from smaller cabinets. This type of subwoofer also works well at the front of the room, and can be used in corners.
A downward-firing subwoofer mounts the bass driver in the bottom, and this approach works well in corners. The output of this style of subwoofer can be increased by using it on a solid floor, though doing so is best avoided if your room is on an upper floor with people below.
Finally, there are subs that combine a forward-firing driver with a downward-firing driver, often in a push-pull configuration where the two drivers are out of phase with each other. This approach can eliminate harmonic distortions and increase the output of the subwoofer.
Should I buy a sealed or ported subwoofer?
Probably the biggest decision you need to make is whether to choose a sealed or ported subwoofer design. As its name suggests, a sealed sub has no openings into its interior, while a ported sub has at least one opening (or port), allowing air to flow freely inside the enclosure.
The benefit of a sealed design is that performance is tighter and more controlled, but at the expense of overall output and extension. Conversely, a ported sub will deliver increased volume and deeper bass extension, while sacrificing a degree of subtlety and definition.
If you have a smaller room, or are thinking of using multiple subs, then a sealed design is probably best because it’s able to deliver a more nuanced performance. If you’ve got a bigger room or plan on using a single sub, a ported model will energise a larger space.
What’s the difference between passive and active subwoofers?
Subwoofers come in two flavours: passive and active. A passive sub requires external power from an amp or AV receiver, whereas an active sub has its amplification built in. All the subs in this guide are of the active variety, raising the question of how much power an active subwoofer requires.
Electrical power is measured in watts (W) and the more wattage available, the louder the sub and the harder you can drive it without distorting, but the higher the price tag. A continuous output of 500W should be more than enough for most people, but if you have the budget you can go higher.
Always look for the RMS (continuous) power output, because this reflects the normal performance of the sub. The peak or dynamic power numbers relate to the maximum output over a short period of time, which can be very deceptive in terms of actual performance.
How do I connect a subwoofer to my audio system?
When it comes to connecting a subwoofer, there are often a number of options available, primarily based around stereo and mono line level inputs using either RCA or balanced XLR connectors. These are also sometimes referred to as low-level or LFE (low frequency effects) connections.
Some subs also include high-level connections that either use speaker terminals or what’s called a Neutrik Speakon connection. The approach uses the same audio signal as the speakers, rather than a filtered low frequency signal, and can be beneficial if music is your priority.
A high-level connection is primarily used for two-channel amplifiers that don’t have a dedicated subwoofer output. However, a multichannel AV amplifier or receiver will have a dedicated subwoofer output, so all you need is a single cable to connect to the LFE input on the sub.
If you don’t like the idea of running subwoofer cables all over your living room, some brands offer optional wireless modules that pass the full-range audio signal with no latency, thus eliminating clutter. Other subs are designed to be used only as part of a wireless system.

What control options do subwoofers have available?
Some subwoofers come with remote controls, which can be useful for adjusting the volume level while sitting in your primary listening position. A remote may also allow the settings to be tweaked without needing to go over to the subwoofer and fiddle with the controls at the rear.
Manufacturers such as SVS and Paradigm even offer remote apps that allow you to complete setup and control of the subwoofer using a smart device. They also include a degree of bass correction, allowing users to optimise the sub’s performance based on the room’s acoustics.
What’s the best place to put a subwoofer?
This brings us to one of the most intimidating aspects of installing a subwoofer – the best place to position it. We touched on this when discussing the orientation of a subwoofer’s driver, but it’s also important to consider how the shape and dimensions of a particular space affect a sub’s overall bass response.
Sound reflects off walls in an acoustic phenomenon called “standing waves” and these waves result in peaks (nodes) and dips (anti-nodes) in a sub’s response. When placing a subwoofer you want to avoid both to ensure a smooth bass response within the room.
A quick and easy method for finding an optimal sub location in a room is to place the sub in the main listening position and play a low frequency test tone. You can then move around the room, and at certain points the sub will sound louder, and at others you will hardly hear it at all. When you find a spot where the bass sounds balanced and smooth, that’s an optimal location.

Do I need more than one subwoofer?
This may sound crazy, but you can use more than one subwoofer. This doesn’t mean that the bass will be louder or overwhelming, it actually results in a more balanced and smoother performance. In fact, a number of AV receivers and amplifiers offer multiple sub outputs.
Two subs, one in each of the front corners of a room, can eliminate many of the issues related to standing waves, and give the bass a greater sense of scale. A third sub at the rear will provide better bass response in the room, and if you can put a sub in every corner you’ll be amazed at the results.
