Best Outdoor Weatherproof Subwoofers

When the weather is fine, most people spend time outside or around the home. If you wish to listen to your favorite music without worries about your speaker, you need to find the best outdoor subwoofer.

Subwoofers for outside are, of course, subject to special weather conditions. They have to be waterproof. Conditions they have to withstand are:

  • Dust;
  • Dirt;
  • Sun exposure (UV radiation and heat);
  • Humidity;
  • Splashing water;

Of course, this also and especially applies to the cabling.

There are various types of open-air subwoofers, but here we consider the most popular among them. The so-called in-ground speakers are particularly suitable for installation in plants and flowerbeds. Only the head protrudes from the ground. The skewers can be placed anywhere in the garden.

There are also waterproof subwoofers that almost completely disappear into the ground. Usually, you bury the bulbous part of the outer boxes in the ground, and only a small opening protrudes. This is particularly suitable for subwoofers, which usually require a larger soundbox.

Where should I put my outdoor subwoofer?

Subwoofers should be placed in locations where the sound is mainly reflected on something and not absorbed by anything (i.e., a wall, fence, or tree). If it is located near a house or another structure, you’ll want to place it so that any sound that reflects off those things will come from the rear, not the front. That means that you will want to point it away from your house and aim it towards the center of your yard.

Can you use an indoor subwoofer outside?

While they are built tough, most indoor subwoofers are not designed to be left outside in the elements. They also have no means of getting power from an outdoor electrical outlet and likely will not provide a high enough level (or any) bass response out by your pool or hot tub.

Should outdoor speakers be covered?

If you plan on keeping your outdoor speakers out for the whole year, then it is a good idea to cover them up when not in use. Rain and snow can often get into the passive speaker cone and cause corrosion or damage to the speaker’s voice coil. If you have an amplifier connected to these speakers, rain and snow will also erode the connections, which will require replacement.

Can you use an outdoor subwoofer in the winter?

A subwoofer should not be used when it is below freezing. Subwoofers are designed to produce low bass frequencies, which means that the voice coil has a large amount of mass and requires significant amounts of power. If this gets too cold, it will become brittle and break due to the repeated large voltage caused by the bass tones. Therefore, it is wise to disconnect the subwoofer before freezing weather.

What kind of wire should I use for outdoor speakers?

When running speaker wire outside, it is best to use 14 or 16 gauge wire. This is thicker than the standard 18 or 20 gauge wire used inside the house and will have an increased resistance to moisture damage.
