The PB-1000 features a 10-inch high excursion driver that creates a floor-shaking frequency of bass without distortion or losing any sound quality. It can reproduce a next level low frequency response that pounds inside of your body and fully immerses you in the movie you are watching or music you are enjoying.
The included amplifier packs a punch with 300W RMS and digital signal processing design. This results in highly precise driver control that reproduces accurate sound at all frequency responses. You will step inside a truly immersive audio experience that has to be heard to be believed.
Distortion is eradicated by the PB-1000 with the addition of huge SPLs and the cabinet design. It is attractive, durable, and designed for accurate sound, with its black ash exterior and a braced interior that includes a custom tuned and ported design. This maximizes the sound quality, ensures that your subwoofer will perform for years to come, and makes for an attractive addition to your home entertainment system.
Our only criticism with the PB-1000 is that due to its immense size, it is bulky and awkward to fit around other furniture. However, the large design allows the enormous bass response, so it’s a small price to pay for superior sound.
If you’re looking for a premium subwoofer to add powerful and accurate bass to your home entertainment system, you can’t go past the PB-1000 by SVS.
2. JBL Professional LSR310S Powered Subwoofer
The LSR310S by JBL is a mid-range subwoofer that combines truly professional and unique design elements for a deep, booming bass best suited to music.

- XLF Extended Low Frequency Setting
- Professional quality construction
The LSR310S is a down-firing 10-inch subwoofer with an included amp that can reach an incredible 200W. Its design includes the JBL patented Slip Stream Port, which works together with the low frequency driver to reproduce a bass that is smooth, distinct, and accurate. The unique double-flared shape of the port maximizes sound at lower frequencies and ensures that the bass lines are pumping at a maximum volume of 113 decibels.
You have the option to achieve the extremely low frequency of 27Hz with the XLF Extended Low Frequency Setting. This feature emulates the pounding bass found in nightclubs and bars, making it a perfect addition to your entertainment collection if you love hosting house parties or events.
JBL is renowned for their superior construction, and the design of the LSR310S is no different in this regard.

The PSW10 by Polk Audio is a great budget subwoofer with huge volume, durable construction, and richly blended sound.
✔️ What we like: Budget subwoofer with design elements that make it worth more than double.
❌ What we don’t like: A limited crossover range.

- Built-in distortion analyzer
- Dynamic Balance driver materials
The PSW10 features a 10-inch driver and its amp handles 50W of power for huge volume that can rock your next party or movie night.
While light on the wallet, the PSW10 is not lacking in its durable design. Its enclosure includes internal bracing and damping that gets rid of internal standing waves and other resonances that can affect sound quality. This leaves behind only the most accurate sound across low frequencies, which moves through a tuned, direct port for maximum bass from 80-160 Hz.
These durable design elements are complemented by Dynamic Balance driver materials, which are stiff and don’t allow additional resonance. This creates a rich and blended sound that rivals that of much larger and more expensive subwoofers.
The addition of a Klippel distortion analyzer ensures that there is no audible distortion at any frequency or volume. It optimizes the woofer’s suspension, position of the motor coil, and motor structure. This allows the sound to move more smoothly and easily across low frequencies, creating an immersive and high-quality audio experience.
Our sole criticism of the PSW10 is that the crossover range is quite limited when compared to other 10-inch subwoofers on the market. However, what it does, it does extremely well, and outperforms other units at its budget price point.

The PWE-S8 by Alpine Electronics simply rocks; it’s small but durable, with fully customizable sound, at a reasonable price point.

If you’re looking for a small but powerful, mid-range, under-seat subwoofer, with durable design and customizable sound, look no further than the PWE-S8 by Alpine Electronics.

Top of its class for car subwoofers, the Hippo84 by Massive Audio is small but features durable and reinforced design at a budget price.

Clarity of sound is achieved by further design elements such as a 2.5-inch Kevlar spun lace voice coil and a paper cone reinforced with Kevlar fiber. This subwoofer reproduces only the cleanest sound, with clear distinction across all frequencies.
While the Hippo84 creates a truly thumping bass, the design is reinforced to prevent any sort of rattling at any volume. This includes a one-piece pole plate that exerts additional motor force, heavy duty direct input wires that connect to the voice coil, and a fiberglass woven dust cap. This means the bass will always be as smooth as possible, and you can genuinely enjoy your favorite tunes unimpeded by irritating sounds.
This is a competition grade subwoofer, designed specifically for car enthusiasts, and small enough to install comfortably within your vehicle.
The only concern with the Hippo84 is that because of its small size, it’s not going to deliver the same depth of bass as a 10- or 12-inch subwoofer. However, considering the budget price of the Hippo84 and its audio capabilities, it’s an absolute steal.
If you’re looking to take your car audio experience to the next level, the Hippo84 by Massive Sound will bring it in spades.

The design of the port is highly intelligent, featuring a high flow that eliminates unwanted noises, facilitates an easy flow of signal to speakers, and reproduces beautiful sound. This is situated within a vented loaded enclosure that is small enough to install in your car for excellent, pumping bass.
Sound quality is superior with the P3-1X12, partly due to its high output sound pressure level that facilitates accurate reproduction of low frequency sound. This, paired with the durable and intelligent design elements, ensures that there is no rattling at any frequency, and just rich and blended bass to enhance your audio experience.
It’s attractive with a smooth black design that you’ll love to show off, and many users have reported that one P3-1X12 is superior in quality to a pair of 10-inch subwoofers from many leading brands. Considering the price tag and quality of construction, this makes the P3-1X12 an absolute bargain.
Our only complaint with the Rockford Fosgate model is that it only has a one-year warranty, which is short considering the price tag. However, the P3-1X12 is so well-designed that you are sure to enjoy years of use without a problem.
If you’re a car enthusiast who is passionate about great sounding bass, the P3-1X12 by Rockford Fosgate is a standout, high-quality, and durable mid-range option.

The only area where the RW8CA falls short is its sound quality at the lowest frequencies. Some users have reported a muddled sound that lacks the clarity of the higher frequencies.

Our only criticism with the Bass Module 500 is that you can only use it with other Bose products. However, if that’s your brand of choice and you’ve been considering a subwoofer under $500, this is the natural choice.

A Guide to Choosing a Subwoofer Under $500
Where are you looking to use your subwoofer?
Where you intend to use your subwoofer will really determine the size and type of unit that is most suited to you.
If you’re looking to add a bass effect inside your car, there are a range of excellent car subwoofers from budget to premium price points.
However, the size of your car and the amount of space that you are prepared to sacrifice will also be determining factors. There are small and compact under the seat car subwoofers of 8 inches that will easily fit in any car and can produce an excellent, smooth bass effect.
However, if you’re able and willing to sacrifice a little more space, you have the option for larger subwoofers that can produce greater bass and have more customizable sound. With the larger subwoofers, it’s important to choose a model that includes internal bracing and durable design to minimize any rattling at high volumes.
For those of you that are looking to add a subwoofer to your home entertainment system, you have a greater range of subwoofers to choose from. If you have a little space to spare, there are larger and bulkier subwoofers that have larger drivers, greater amplification abilities, and more options to customize your sound. You have the option of both powered and standalone subwoofers, depending on whether you already have a suitable amp.
You’re likely to have guests around, so it’s always important to choose a subwoofer that is attractive and will blend in with the existing aesthetic of your entertainment system.
Some subwoofers are designed to integrate with other technology from the same brand, like Bose. If you already have a home entertainment system from a particular brand, it makes sense to choose a subwoofer that will effortlessly pair and is optimized to work together with that brand.
If you’re looking for a subwoofer to add impact to parties, special events, or even a nightclub, there are excellent portable options with wheels and handles that can be easily transported and set up.
How experienced are you with subwoofers?
Whether you are a complete novice, or an experienced audiophile makes all the difference in which subwoofer under $500 is best going to serve your needs.
For the less confident, there are excellent subwoofers that operate in a plug and play format, with simple controls. This will allow you to get used to the audio capabilities of subwoofers without needing to invest in an expensive and complicated unit that will overwhelm you.
If you’re looking for that high-quality, customizable sound, there are a variety of subwoofers under $500 that can suit your needs.
At an intermediate or advanced level, there are amazing subwoofers with controls that allow you to customize sound quality. Many subwoofers include variable phase control to allow better integration of sound. A control for low pass crossover blocks high frequency sounds and lets you reproduce the lowest frequencies at the highest quality.
If the subwoofer includes customizable gain, you can control the sensitivity of your system for optimal bass, and some subwoofers even include a bass booster function for that real nightclub effect.
What’s your budget?
How much are you willing and able to spend? This question will decide your starting point when choosing a subwoofer under $500.
At the budget end, you can choose from affordable but still high-quality subwoofers that have user-friendly controls and installation. These are usually compact units, of a smaller subwoofer driver size and moderate amplification abilities. They can reproduce a smooth, clean bass that will vastly improve the quality of your music or movies but won’t blow your head off with volume or shake your walls with throbbing basslines.
At the mid-range price level, you have more options for subwoofers of different driver sizes, levels of amplification, and customization of sound. You can choose subwoofers of 10 or 12 inches in driver size with larger amps that can really rock your socks off. Mid-range subwoofers also include more controls for sound quality, durable designs, and internal bracing that protects against rattling or distortion.
If you are looking to invest in a high-quality subwoofer, then the sky’s the limit. Premium subwoofers feature high quality construction, highly customizable sound, and greater sound capabilities. These subwoofers have a design that is both attractive and durable, often with unique, patented port designs that ensure only the cleanest reproduction of bass.
Premium subwoofers are larger, often 10, 12, 15 or even 18 inches in driver size, with superior amplification and the ability to reproduce truly wall-shaking bass. They include multiple controls for different aspects of sound, so if you are a true audiophile you can achieve the bass that your music deserves.
