Best 8 Inch Subwoofer Reviews

Deciding between a larger or smaller subwoofer for you car audio sound system is incredibly important because there are many variables to figure into the equation such as the woofers specifications, enclosure type, amplifier driving the subwoofer, voice coils …AND size!

So, if you’re aiming to build a stereo system with great sound quality and you have enough space inside your vehicle, then it’s wise to opt for a larger subwoofer.

However, if you’re driving a small dinky vehicle that can’t accommodate a large subwoofer, smaller subs such as an 8-inch or even under seat subwoofers will add a relatively decent thumping bass to any vehicle from the tightest spots.

Granted, an 8-inch subwoofer won’t turn your ride into a rolling thunderstorm of bass by any means compared to big subwoofers with larger cones. Large subs have more cone area, thus they can produce more air pressure which results in booming bass.

However, don’t under-estimate smaller subwoofers. A properly powered 8 inch subwoofer mounted in a suitable enclosure can make a night and day difference for your audio system.  Especially if you have no subwoofer at all.

Kicker CompR 8" Subwoofer Review

Kicker is one of the best car subwoofer brands out there. They offer a huge array of subwoofers of different sizes and types at a very reasonable price.

We've had the opportunity to try and mount hundreds if not thousands of subwoofers in various vehicles over the years. We've tested and compared varying subwoofers from different brands, and we believe that the Kicker 10C84 is a great for the price. I mean, less than $50? That is a major bargain.

The Kicker CompR subwoofer is one of the best cheap 8 inch car subwoofers that you can buy for under $50. It has a frequency range of 30 - 500 Hz, and can handle up to 100 watts of power on continuous basis.

The CompR features a flex-resistant polypropylene cone with 360-degree back bracing for hard-hitting lows without distortion. Its ribbed foam surround offers long excursion and maintains better sound linearity, while the double stitching ensures reliability and long lasting of the subwoofer even under excessive load.

Additionally, its sturdy steel basket frame provides a solid base for its relatively big bass output, and the extensive venting assures absolute heat dissipation without breakdown.

In terms of cons, it's really difficult to think of any. If anything, I'd say that the sensitivity rating of this subwoofer is below average, therefore, it will require a high power wattage input than a subwoofer with high sensitivity rating.

Having said that, it feels to me like nitpicking especially considering the price. All in all , This legendary Kicker Comp subwoofer is the perfect balance between high value and high performance!

This is going to be the most expensive pick of the lot by far. And assuming you've got enough money to thrown around, the JL Audio 8W7AE-3 is one of the top-notch 8 inch subwoofers you can buy.

The 8W7AE-3 is a very well-conceived and well-engineered subwoofer. It features a dish-shaped outer cone that's supported by a second W-shaped inner cone attached to the sub's voice coil structure. This design allows for solid, yet lightweight cone that's very responsive which results in accurate bass without distortion or noise.

This subwoofer also features the "OverRoll woofer cone" design. This design is also called "Plus One Cone Technology" and it's used by other subwoofer brands such as JBL, Infinity ...etc. It basically lets the surround wrap around the outside of the mounting flange which results in more usable cone area, thereby the sub moves more air for deeper lows.

JL Audio went a step further and used their exclusive FCAM (Floating Cone Attach Method) technology. Which is a precision engineering that simply aligns the voice coil, and woofer cone for incredibly linear woofer movement, which means you'll hear exceptionally accurate profound bass.

All in all, the 8W7AE-3 is a very well-built subwoofer. It's built to JL Audio's meticulous standards. JL Audio put 30+ years of sonic expertise into their legendary W7 subwoofers, so deep and powerful bass is to be expected.

If I had to pick some criticisms for the JL Audio 8W7AE-3, it would be just the price. However, something this good is naturally expensive.

Final Thoughts

The bottom line is that if you want to build a solid sound stereo system, and you've got enough space to accommodate a large subwoofer, we would definitely recommend going that way. As a general rule of thumb, larger subwoofers have more woofer cone area, thereby, they can move air which translates to bigger bass.

However, if you don't listen to bass heavy music and you're just wanting your sound system to deliver a well-balanced sound output, then smaller subs are the way to go. These subwoofers aren't just cheap, but they're also quite easy to install compared to larger subwoofers. They are a great way to to add decent bass for those of you who are on a tight space-and-money budget.
