Best 18 Inch Subwoofer

If you are reading this, then you are probably looking for a clean sound for your speakers. Best 18 inch subwoofer are grossly overlooked when it comes to setting up a good audio system. 

Just because it is a "sub"-woofer does not mean it is not important. It is, in fact, a very crucial component of your audio system. Usually, a basic sound system needs low-frequencies between a 20-200Hz speaker.

Subwoofers produce low-frequency sounds and your single-speaker setup will not deliver an adequate sound quality. Where is the fun in car rides if you cannot blast your favorite songs? Subwoofers of 12-16 inches provide volume, but they fall short when it comes to low-frequency sounds.

What features to consider while buying the best 18-inch subwoofers?

Either you are looking forward to investing in the best 18 inch subs for the first time, or you have an existing high-end audio system installed in your home or car and looking to upgrade it, you need to check out this buying guide.

The 18-inch subwoofer listed in this article is some of the largest and the most potent subwoofers you can find out in the market. That said, you must know what features to consider before investing in the 18-inch subwoofer.

Peak power:

Peak power is one of the crucial factors to consider because it tells you how much power the subwoofer can handle or operate. So by checking out the peak power, you can easily get an idea about the maximum performance it can deliver.

Peak power rating will be given in watts. With that said, the peak power of your 18in subwoofer includes ratings like 1000 watts, 1500 watts, 2000 watts, and 3000 watts or may higher rating. It mostly depends on your subwoofer model. If you are looking for a very loud sound and high performance, then we suggest you go with 3000 watts peak power rating.

Frequency response

Even if you succeed in getting a loud, powerful, and high-performance subwoofer, you won't be able to get most of it out if you have not paired it with your speakers for better audio quality and detail. So frequency response of the speaker is important so that you get to know whether the subwoofer offers proper detail.

The higher the frequency response, the larger it will produce a large number of frequencies. You can find frequency response ranges like 20 Hz to 500 Hz, 40 Hz to 250 Hz, 18 Hz to 300 Hz. And here we suggest going for 20Hz to 500 Hz for the best experience.

Form factor

The next feature to check is the form factor. Though the form factor doesn't affect the subwoofer performance directly, it might cause trouble while installing it. You can find subwoofers with enclosure boxes in the market. Though they come ready-made and are pretty easy to install, they may not fit into tricky areas. Meanwhile, if your subwoofer lacks an enclosure, the subwoofer would cost less and can be installed in any type of enclosure based on your preference.

Woofer size

Though we have listed only 18-inch subwoofers, it is crucial to check the woofer size or the woofer driver size so that the form factor and woofer unit size are not affected.

Power requirements

You need the power to make your subwoofer work, be it an entry-level one or a powerful subwoofer. If the subwoofers are passive, then you need to offer external power to them through an amp. If you don't have an amp, then consider buying it if you want high-performance 18-inch subwoofers.

Warranty

You need to check the warranty of the 18-inch subwoofer because they are a bit expensive. If you are investing in a beginner-friendly product, then you can check the build quality. Whereas if you are investing in high-quality ones, then check whether the manufacturer offers a minimum 1-year warranty. 

FAQ

1. Are 18-inch subwoofers worth it?

Though the 18-inch subwoofers are relatively on the pricer side, they are extremely powerful and can produce loud music which can be heard clearly from a distance. Since the subwoofers are large in size, they are considered for delivering powerful sound.

2. Does a bigger subwoofer mean more bass?

Yes, most of the big subwoofers have better bass output when compared to the small subwoofers in small boxes. If you are looking for loud and deeper bass, then 18-inch subwoofers which are the biggest subwoofer on the market are mostly preferred.

3. Are 15 or 18-inch subs better?

This is quite subjective, and so the answer depends on one's personal favorite. 18in subwoofers are larger in size than the 15 inches, so if you want your subwoofer to sound very loud, then go for the 18-inch subs. 

CONCLUSION

The subwoofer is the backbone of your audio system. It can capture the lowest audible frequencies to produce the deep bass sounds you usually hear in music. It is okay to be intimidated if you are new to this. Just keep in mind a few things while buying a subwoofer.

The subwoofer should have good RMS power handling capacity, higher quality magnets, thicker voice coils for reducing distortion. Look out for the low-frequency extension. Subs that can handle lower frequencies have lesser distortions. Additionally, consider its weight, size and finally, the price. That is all. Now go ahead and get ready to jam to some EDM music!
