Picking the 8-Inch Subwoofer of Your Dreams

Eight-inch subwoofers are wildly popular for a simple reason: they combine powerful sound with a compact size. To help you find the perfect audio experience, we set out and researched 40 new and bestselling 8-inch subwoofer models. From the best subwoofer brands to ones you may not have heard of, we didn’t discriminate. The results are the subwoofer reviews below. Before we get started, here’s what you need to know when shopping.

Best 8 Inch Subwoofers

Peak Power: Peak power wattage is the maximum watt output the speaker can handle for short bursts. It’s important but also keep RMS power in mind.

Best 8 Inch Subwoofers

RMS Power: This wattage is the average or continuous power your subwoofer uses. It is the most reliable measure of the volume and sound you’ll get.

Picking the 8-Inch Subwoofer of Your Dreams

Ohm: This measures the so-called impedance of your subwoofer in ohms. The lower it is, the more easily electricity flows through the speaker.

Voice Coil Size: A larger voice coil offers better audio, has better control over the audio cone, and can handle greater power than a smaller one.

Top 10 Products

Ready to take your commute from boring to bass-heavy? Our top 10 subwoofers in the 8-inch category may be small, but they don’t sound like it. In fact, they offer high-end audio with plenty of power. If you’re in a hurry and simply want to find the best subwoofer for the money, check out our top pick and budget pick. They are both smart choices. Let’s get started!

Rockford Fosgate P2D2-8

Top Pick
Surprise, surprise: Popular brand Rockford Fosgate is one of our top picks! The P2D2-8 has all of the things we love about the company’s subwoofers: They offer VAST design (Vertical Attached Surround Technology) for additional cone surface area without changing the dimensions of the frame, conforming to the CEA-2031 industry standards – plus, lots of features designed for durability even under a heavy load. The paper cone is reinforced with Kevlar, while the anodized aluminum dual voice coil has a spun-laced Nomex insulating reinforcement collar. The dual liner spider has embedded 16-gauge tinsel leads, and the StampCast basket has integrated spider venting as well. It’s perfect for standard sealed or vented enclosures, and the Flex-Fit mounting pattern lets you make small adjustments to the subwoofer even after it’s been mounted. All in all? This is a powerful and well-built subwoofer that’s designed to last for years of heavy bass bliss!

Planet Audio AC8D

Budget Pick
Planet Audio could honestly be our favorite subwoofer brand for the warranty alone: three years! Where most subwoofers offer one year, three years is a great extra that shows the manufacturer’s quality. The best part? This subwoofer is also affordable and sounds fantastic! The AC8D is a remarkably cheap subwoofer that features a dual two-inch voice coil for a range of setup possibilities. The poly injection cone and foam rubber surround ensure accurate and intense sound and a durable subwoofer. The 600W RMS power and super high 1200W peak power is very impressive for an 8’’ subwoofer, too! The 85dB sensitivity is a good choice for car audio, though the standard is 89-95dB for the greatest power efficiency. But for such a low price, it’s hard to beat the build and sound quality you end up with! We highly recommend this product.

Polk Audio db840DVC

Review
Want a subwoofer that can stand up to a little weather? The Polk Audio DB840DVC is marine certified, perfect for mounting in the back of a jeep, boat, or another outdoor vehicle. With 180W RMS power, it may be compatible with your car’s factory audio system for easy installation. The polypropylene cone has a vented coupler to stiffen the cone for stability and less distortion. Next, comes the Santoprene surround and flat NOMEXA spider. The four-layer Kapton voice coil former is triple vented, along with the cone/coil coupler and pole piece, for reliability and durability. The 85dB sensitivity means it will have relatively good power efficiency when you start to turn up the volume, too.

Pioneer TS-SW2002D2

Review
Shallow mount subwoofers are the perfect solution to today’s car designs, and the Pioneer TS-SW2002D2 has a top-mount depth of just 2.6 inches. Despite being an 8-inch subwoofer, this option from Pioneer Electronics has an oversized cone to help provide more accurate base while still being easy to install. This cone is made from mica-injected molded resin that is rigid and durable. The dual 2-ohm voice coils give you flexibility in how you install this subwoofer into your system. An 86dB sensitivity is about average for car audio subwoofers but more efficient than many subwoofers on the market! The 150W RMS power is a good option for installing this subwoofer with a factory car audio system, which tends to be compatible with that power draw.

Rockford Fosgate P2D4-8

Review
Rockford Fosgate makes it so, so easy to choose Rockford Fosgate… The P2D4-8 subwoofer has their signature features: a VAST Vertical Attached Surround that increases the cone area without making installation harder, a Flex Fit basket frame to allow you to adjust the subwoofer a bit after it’s been mounted, and amazing power handling. The paper cone is reinforced with kevlar fiber for durability on top of clear sound. Up next is a high-density poly-foam surround and cast aluminum trim ring. Rockford Fosgate recommends using sealed and vented enclosures for best results. An 83dB sensitivity is pretty good for most car audio systems as far as efficiency and power draw, too. And with 250W RMS power, you’ll be jamming out at high volumes in no time!

Pyle PLPW8D

Review
The Pyle PLPW8D won’t let you down with 400W of RMS power ranging up to 800W peak power. The dual four-layer voice coil is a solid asset to your bass production. Combine that with a non-press paper cone, specially treated foam surround, and black steel basket, and you’re ready to rock. The SPL sensitivity of 89dB is right within the ideal 89-95dB range for car audio. The bumped and vented motor construction combined with the rubber suspension increases durability for a long lifetime of amazing low-frequency sound. If you heard this out in the wild, you’d probably never guess it was an 8-inch subwoofer!

DB DRIVE WDX8

Review
The DB Drive WDX8 3K has dual 4-ohm voice coils for a broad range of hookup options in different systems. The cone is surrounded by high roll foam and low-carbon steel and bottom plates, plus a high-excursion spider design. The 100oz ceramic ferrite magnet creates intense drive behind your music. The 84.1dB sensitivity isn’t the best we’ve seen, although DB claims this subwoofer is optimized for SPL. Still, the 600W of RMS power is a big load for pushing that bass we all know and love. It seems to be optimized for dubstep and other bass-heavy music. This is a good everyday subwoofer for amping up your current audio system!

Skar Audio VVX-8v3 D4

Review
Not just for car audio, the VVX-8V3 D4 might just amp up your next house party, too, if you install it in your living room. The two-inch high-temperature dual copper voice coil gives you more wiring hookup options than a single coil. The competition-grade paper cone is a solid foundation of many great audio systems over the years, but that triple-stack ferrite motor might be a little more impressive when you’re showing your new woofer off to your friends. With 83.9dB sensitivity, this subwoofer is relatively efficient with how much power it needs to produce the bass YOU need. The construction is super durable down to the chrome back plate finish. Take all of that into consideration, and you won’t be disappointed.

Kenwood KFC-XW800F

Review
Limited on space? The Kenwood KFC-XW800F is a shallow-mount subwoofer with a 2.75-inch mounting depth. You can get a little creative with how you mount it with that on your side! It has a single 4-ohm voice coil and a sensitivity of 78dB. A sensitivity less than 80-85 means it’s less efficient than the average subwoofer, so it will need more power to produce the same amount of sound as a more efficient option. Here’s the thing: it’s still a good subwoofer with great sound. The cone is made from carbon glass fiber with a butyl rubber surround and dual magnet drive. The aluminum-cast basket combined with the heat transfer system help keep the woofer cool. And at 150 RMS power, this subwoofer is compatible with most factory car audio systems! It’s perfect for adding a boost to your current system or as part of a new setup.

Kicker Compr Subwoofer

Review
The Compr CWR82 subwoofer features dual voice coils with 2 ohms each for a combined 4 ohms. Dual voice coils give you more wiring options when you’re installing your subwoofer. At the center is an injection-molded seamless polypropylene cone for distortion-free, powerful sound. Santoprene forms the surround, and horizontal and vertical Quad Venting slots are located under the cone for extra cooling. The whole thing is contained in a stamped steel basket with large progress-roll spider and spring-loaded push terminals. Phew! The results: 300W RMS power and 82.1dB sensitivity. That sensitivity level is on the low end of the 80-100dB range, but it is small enough that it shouldn’t destroy your power supply. Overall, the CWR82 subwoofer is a tough and hard-working bass thumper!
