18 Inch Subwoofer Buyer’s Guide
There are some key differences that you’ll find between different 18-inch subwoofers that are on the market. To make sure that you choose the best 18-inch subwoofer for your needs, then consult this buying guide, which will explain the key features found on these subwoofers, and what they mean.
Maximum Power/Continuous Power
Maximum power is just that: the absolute peak power that the speaker can handle, but only in short bursts. No subwoofer is capable of performing at just its peak power. That’s what the RMS number means, which is important for working out the continuous peak power that the subwoofer offers. Check both numbers to make sure that your new subwoofer will function as part of your sound system.
The best 18-inch subwoofers will feature an enclosure constructed out of a durable, hard material that will enhance the heavy-duty nature of the subwoofer. One of the best materials for this purpose is MDF (Medium-density Fiberboard). The thicker the material, then the more durable and hard-wearing the subwoofer will be.
Rubber feet are an important consideration for the stability of the speaker. Metal corners, as well as a metal grille (preferably made from steel), will also ensure that your 18-inch subwoofer is heavy duty and won’t break or be damaged easily.
The two main attributes that contribute to portability are the design of the handles and the weight of the unit. An ergonomic design – often with handles inside deep recesses – will allow for much easier carrying.
And then, of course, the lighter the 18-inch subwoofer is, the easier it will be to carry too, but you need to make sure that the speaker isn’t so light that it may move around when the bass is pumping through it.
When it comes to the voice coil in an 18-inch subwoofer, you’ll tend to have a choice between a 3-inch voice coil or a 4-inch voice coil. The difference between the two is minimal, and this feature should only be considered as one element of the subwoofer. There’s no need to simply choose one subwoofer over another because of the size difference in the voice coil.
If you’re looking for an 18-inch subwoofer for live performances, then check if it's pole-mountable, as that will come in handy.
What’s the difference between a powered 18-inch subwoofer and a passive 18-inch subwoofer?
A powered subwoofer – also known as an active subwoofer – will include an amplifier inside it, whereas a passive 18-inch subwoofer does not include an amplifier inside the cabinet. Basically, this means that a powered subwoofer is ideal for people who are using a sound system that doesn’t include a third party amplifier, whereas a passive subwoofer is only for people who have an audio system that includes an amplifier.
Don’t forget that deep bass and maximum power isn’t everything when it comes to a subwoofer. If you’re planning on using the subwoofer for live performances, then you’ve got to make sure that it isn’t a hassle to carry.
Check that it has handles that are either ergonomically designed or a deep-recessed so you don’t have to struggle every time you carry it into a venue. Of course, the lighter it is, then the easier this will be too.
