18 Inch Subwoofer Buyer’s Guide

You'll note some important differences between the various 18-inch subwoofers that are on the market. Then consult this buying guide, which will clarify the main features found on these subwoofers, and what they mean to make sure you choose the right 18-inch subwoofer for your needs.

Maximum Power/Continuous Power

Maximum power is just that: the absolute peak power that can be managed by the speaker, but only in brief bursts. There is no subwoofer that can only operate at its peak capacity. That's what the RMS number means, which is essential for the continuous peak power that the subwoofer provides to be worked out. To make sure that your new subwoofer can act as part of your sound system, check all numbers.

Enclosure Construction

An enclosure made of a robust, hard material will feature the best 18-inch subwoofers that will improve the heavy-duty design of the subwoofer. MDF is one of the finest materials for this reason (Medium-density Fiberboard). The thicker the stuff, then the subwoofer will be more durable and hard-wearing.

For the stability of the speaker, rubber feet are a major factor. As well as a metal grille (preferably made from steel), metal corners will also ensure that your 18-inch subwoofer is heavy duty and will not easily crack or be harmed.


The configuration of the handles and the weight of the device are the two principal attributes that contribute to portability. An ergonomic design would allow for much easier carrying, often with handles within deep recesses.

And then of course, the smaller the 18-inch subwoofer is the easier it will also be to bring, but you need to make sure the speaker isn't so light that when the bass pulses through it it will travel around.

Voice Coil

You seem to have a preference between a 3-inch voice coil or a 4-inch voice coil when it comes to the voice coil on an 18-inch subwoofer. The difference is small between the two, and only one aspect of the subwoofer should be considered to be this function. Because of the size gap in the voice coil, there's no need to simply pick one subwoofer over another.

Pole Mountable

If you're looking for an 18-inch live performance subwoofer, then check if it's pole-mountable, because that's going to come in handy.

What is the difference between an 18-inch, powered subwoofer and an 18-inch, passive subwoofer?

A powered subwoofer will have an amplifier inside it, also known as an active subwoofer, while a passive 18-inch subwoofer does not include an amplifier within the cabinet. Basically, this suggests that a powered subwoofer is suitable for individuals who have a sound system that does not have a third-party amplifier, while a passive subwoofer is only appropriate for individuals who use an amplifier-inclusive audio system.

Expert Tip

Don't forget that when it comes to a subwoofer, deep bass and full power are not all. If you're going to use the subwoofer for live shows, then you have to make sure it's not a problem to bring around.

Check that it has handles that are either ergonomically built or deep-recessed, so any time you take it into a venue, you don't have to fight. The lighter it is of course, so the faster it will be too.
