So, What’s A Free Air Marine Subwoofer?

A free-air marine subwoofer is a simple subwoofer mounting system that eliminates the need for large speaker enclosures.

The subwoofers deliver good audio performance without a mounting box, making it easy to install one on the rear deck, between the back seats. Of course, you can design your subwoofer box as well.

By the nature of your boat’s dimensions, you’re likely to mount a free-air subwoofer in locations where a box can’t be used.

The boat’s body makes an airtight seal with the speaker and turns any space behind it into an enclosure. That’s popularly known as an Infinite baffle (IB) design.

If you plan to install it in your boat, you’ll need to ensure that the subwoofers you choose are marine grade and well-enabled for fresh and saltwater.

However, you can also install them in your car’s trunk. Here are the advantages and drawbacks of using free-air subwoofers.

Free Air Subwoofers Pros and Cons

As earlier revealed, saving space is the main advantage of a free-air subwoofer. It can deliver a solid audio performance with enough bass without bearing the burden of adding weight to your boat with a heavy enclosure.

The speaker is also versatile in installation, allowing you to fit it in any location you need as long as there’s space behind the speaker. Free Air Marine Subwoofers

You should note that free-air subwoofers may compromise the sound quality, so they are not as good competitors in a sealed box.

However, you can also install a free air subwoofer in a sealed box to improve its performance – if you don’t mind carrying the burden of weight and space limitations.

Those who enjoy heart-thumping sounds will also want to be gentle on the volume levels when using a free-air subwoofer.

If you start playing the sub at maximum volume levels, there’s a big chance of damaging the speaker as it doesn’t have a nice air spring. That said, here are the best free-air marine subwoofers on the market.
