Best 18-Inch Subwoofer Reviews 2020: It’s Not All About the Boom
You are here because you like clean sound at high volume. With your experience as a bass enthusiast, you are yet to know what enough bass means.

They don’t hit hard, and trying to stretch their potential with the EQ can actually blow them up. Life is too short for weak subs.

Factors to consider when selecting the best 18-inch subwoofer
The ability to blast music is means unlimited fun for the majority of bass fans. What’s not fun is finding a big subwoofer that delivers this value sustainably and affordably. The selection process can even be stressful especially if you aren’t sure about what considerations to make to ensure that you end up with the best sub for your system and listening needs. It is noteworthy that not all big subs perform better than smaller subs. The reasons for this relate to crucial performance factors of which you must be privy when you go out shopping.
This section serves the purpose of highlighting the important factors to consider when evaluating 18-inch subs and comparing different offers on the market.
It has been said repetitively that a subwoofer is only as good as the power behind it. And when it comes to consuming power, 18-inch subs are really greedy. You don’t want to have a great sub but without adequate power for it.
In most cases, power deficiency is the cause of distortion and unappealing boominess in large sound drivers. Controlling the essential sound reproduction components such as the cone and surround is not easy due to the large surface area of these components. For this reason, poorly engineered and inadequately powered subs struggle to control the underlying pistonic movement and can never produce accurate bass.
In addition to considering RMS power handling, assess the sub’s magnet and voice coil. Bigger, higher quality magnets and thicker voice coils enhance better control over the driver. Thus, the sub is able to deliver big, quality lows without distortion and muddiness.
Powered vs. unpowered subwoofer
Powered subs come with their own amplifiers. For example, Electro-Voice ELX200 uses an inbuilt 1200w class D amplifier. This sub doesn’t require you to hook it up with another sub. Besides, you can wire the sub with other smaller speakers in your system to power them.
Passive subs, on the other hand, don’t have in-built amp and rely on external amplification.
Both options have their advantages and disadvantages, and your preferences determine the better option. If you already have a powerful amplifier in your audio system, you may be good to go with an unpowered sub. On the other hand, if you don’t want to buy a sub and an amp separately, you might find a powered sub more attractive.
Low frequency Extension
The frequency response of a sub is considered among the most crucial factors of performance. A sub that handles more low frequencies can deliver deeper bass. The numbers to look out for are the lower end of the frequency response. For example, the frequency response of Rockville PBG18, our top pick, is 35Hz – 4KHz. This sub can handle frequencies as low as 35Hz. Sound pressure level (SPL) is related closely with frequency extension. Greater SPL is better in the production of low-end sound, so you want to be keen on this rating when comparing subwoofers.
Go for brands with a reputation of cutting-edge engineering. Purchasing an 18-inch sub is considerably a serious investment in your sound systems, and you don’t want to start looking for a replacement for your new but unrewarding sub. Top brand subs are designed to win the deep bass extension without giving up speed in transients and accuracy in frequency response. This quality of engineering is not achievable without huge investments in research and development, and you can be sure that only the big brands have the budget for R&D.
Top subwoofer brands are also known for their use of premium parts in the design of their products. Such high-quality parts not only promise serious sound performance but also enhance the durability of the products.
Size and weight of the subwoofer
18-inch subs weigh differently and come with different enclosure. These two aspects affect whether and how you will use your chosen subwoofer. If you are searching for a car subwoofer, consider the desired placement location of your sub, making sure that it will fit in your car. If you are a sound production professional, you might need to transport your speakers to different event locations. Think about portability aspects in the design of the unit.
Hopefully, you can now make your own comparisons between different 18-inch subs and settle on the one that best fits your needs.
