Reviews of the Best Small Subwoofers

1. Definitive Technology ProSub 800

Our experts’ first choice is the Definitive Technology ProSub 800. It’s a small subwoofer that fits into a more compact home theater setup. 

Most compact subwoofers come in at about 8-inch driver with impressive peak power outputs. You can expect 300 watts from this powerful bass sub for expansive acoustics that fills a large room.

You can incorporate other components of this subwoofer to the home theater system to create a full-fledged cinematic experience. The ProSub 800 comes with many connection options and four adjustable feet that protect your floors and can accommodate different heights.

Pros

Cons

2. Polk Audio PSW111 8” Subwoofer

The Polk Audio PSW111 does not need an external amplifier for heightened deep sounds. It features a good bass response for low frequency signals but it is also heavier due to the built-in amp.

The tiny sub measures in with an 8-inch woofer profile that makes it a small but powerful subwoofer with 300-watt energy output. Add extra bass into your surround sound systems to create good bass sound never before experienced. The sub is tuned in such a way to give range and height to the deep soundstage at any volume.

The powerful subwoofer is highly efficient and has a removable grille design to give more reach to the strong firing speakers.

Pros

Cons

3. Sunfire XTEQ 8 High Performance Powered Subwoofer

The Sunfire XTEQ 8 is 10x more powerful than most compact subwoofers with a peak power output of 3000 watts. It still features an 8-inch woofer profile like any other compact subwoofer but does a better job at projecting lower sound frequency response and is one of the best for loud bass.

The subwoofer comes with a high-powered digital auto-EQ circuit to calibrate the speaker to fit your room for great surround sound effects. The XTEQ can connect easily to other devices in your home setup to get the best bass effects.

The small and compact sub has a powerful driver and four rubber feet to protect your floors at high level volumes.

Small Subwoofers Buyer’s Guide

In this section, our experts have listed the important characteristics to look for when buying the best small subwoofers. It’s not only the size and power that counts, but also the audio quality.

Design and Build

A small and compact subwoofer’s first bragging point is size. You will find most of them to be about 8 inches but there are some 10-inch driver options as well. They are not as heavy as the top-rated twelve-inch subwoofers. The extra two inches may not give you a lot of extra power and won’t fluctuate the price by too much.

Do you want a powered or passive speaker subwoofer system? One with an amplifier, preferably a class D amplifier, will save you a lot of hassle. One without an external amplifier would mean more time searching for a compatible one. 

For example, the Polk Audio PSW111 comes with a 150-watt internal amplifier that boosts the power output to 300 watts. If you have a powered subwoofer, be aware that it will add weight to the size, but it won’t take up any more space.

Look for a subwoofer with a detachable grille pattern. It’s better to find one that allows you to dismantle the front so there are no obstructions in the way of the low quality bass relays. 

Sound Quality

The quality of the bass is another factor that will affect whether or not you buy the product. Extra features such as room calibration and downward-firing passive radiators or drivers will do wonders for the music quality. If you want minimal hassle without the need for customization and adjustments, look for special technologies such as the Digital Auto-EQ circuit for room calibration as seen in the Sunfire compact subwoofer.

The placement of your sub will also affect the music quality. Since we are recommending the best compact subwoofers, there will be plenty of flexibility in terms of placement that can make the most of the frequency response range. A subwoofer is better placed closer to your listening spot.

Even though these best subwoofers are portable like SVS SB-1000 that can be fixed in any corner of the room, our experts suggest placing the subwoofer beside your couch, under it, and even behind it to really experience the low rumbles.

Bass

How is the bass from your subwoofers? At any price and any size, you would expect a well-built subwoofer than can deliver the designated frequency range with a ton of power and no distortion. Look at the drivers and examine the materials to know if it’s worth the price. 

Copper spun woofers for example offer enough rigidity and flexibility to accommodate the give needed to deliver deep bass vibrations for your music and movies.

The designated subwoofer box can affect the sound quality of your device, here are some hacks to make a subwoofer box deliver powerful sound and performance

Power Output

One of the most important things about how loud your best subwoofers can get is dependent on the power output. There are two figures to look at — the peak power and the RMS. 

RMS stands for root mean square. The RMS is the more important statistic to examine. It refers to how much power the driver can deliver consistently over a long period of time in watts.

The peak power watts, however, is what most people focus on. Our experts say this is incorrect because the peak rating refers to how much power your speaker driver can get to in short periods. Since the peak number is often higher than the root mean square, it seems like the more appealing one to keep in mind.

However, our team warns that playing your subwoofers at the peak rating for long periods can damage your devices that may lead you to having a faulty or blown speaker subwoofer. If you want a little bass with your home speakers, the root mean square is more than enough to produce enveloping and reverberating bass.

Low Distortion

The distortion is about the music quality from your subwoofers when played at loud volumes. Speakers and subwoofers can have added technologies to tweak the bass a little to help with the distortion. The Digital Auto-EQ circuit for room calibration is a fine example of what can help with the sound distortion and minimize or eliminate its impact.

Hardware Compatibility

To connect your best subwoofers into your home system, you need the right connections. You shouldn’t buy a product that isn’t compatible with your existing setup, so look for a device that features all the right connections.

Speaker level inputs are crucial to the operation of passive subwoofers. Speaker level inputs are what’s needed to connect an external amplifier to your sub. There are higher and lower speaker level inputs so our experts wish to remind to make sure that the subwoofers you get have the same speaker level inputs. On the other hand, active subs can have more powerful bass when it is connected by a subwoofer pre-out

Like Sonos Sub (Gen 3), you can also choose to transform your best subwoofers into wireless options with a wireless subwoofer kit. 

Extra Features

The best compact subwoofers need to go down to at least 20 Hz frequency response [1] unlike the best 8 inch subwoofers with at least 55 Hz. This is the lowest range human ears can muster. However, if the frequency range of the speakers and subwoofers you go for can reach 35 Hz, that will nicely round out the soundstage and give you decent vibrations.

Also, look at which way the speaker is firing. You can either have front or downward-firing passive radiators. If you want vibrating rumbles, then you need your compact subwoofers to fire down. This will reflect and radiate the bass to the floor, resulting in booms you can feel.

If you go for the front-firing option like in the PSW10 vs PSW108, then the low bass tones from your compact subwoofer will be directed towards you. There is no better choice for good sound, just personal preference.

Price

Our experts always try to find different sizes, appearances and price range when listing our best choices. As you can see, the best compact subwoofers can exceed the 500 price range or stay below it. 

The price matters when you want extra features such as room calibration technology. If you want compact subwoofers whether it is an active or a passive sub, it should give you the thunderous rich and deep low-end tones you want, you need to be prepared to shell out more for the experience.
