Best outdoor subwoofer
OSD Audio FORZA-10 10″ Weather-Resistant Outdoor Subwoofer with 300W of Power and High-Impact Molded IP66-Rated Enclosure. Read the full review.

Weatherproof subwoofer must have specific properties allowing it to work correctly even in not the most pleasant conditions. Such devices should:

  • not to be clogged by dust and dirt;
  • not be afraid of the sun (ultraviolet radiation and heat);
  • be resistant to humidity and splashing water.

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

There are different types of open subwoofers, but we will consider only the most popular ones in this review. The so-called in-ground subwoofer is ideal for installation on the ground. Only the head protrudes on the surface. And the skewers can be placed anywhere on the site/yard.

There are also conventional outdoor powered subwoofers, which can simply be placed on the ground (any surface), and you can enjoy the music.

I have collected different variants of such models for you, conducted numerous tests, and now I am ready to share the results so that you can choose the optimal model. So let’s not waste time and move on to the most interesting part!

We don’t recommend



It was a really good model in its time, but today it is inferior in many respects to its analogs. However, there is already on the market the OSD FORZA 10, which I consider a very successful development of this model. Why? Read on, and you will find out.


  • It is an outdated model, and on the market, you can find better subwoofers in quality and price.
  • Inconvenient speaker connection procedure.
  • It does not have enough power to create deep bass.
  • The device rattles where the top and bottom parts join at above-average volume.
  • The fixed crossover is too high, and its output is too low, so the sound is unbalanced.

It is quite a powerful subwoofer with 300W of power and wonderful music. It effectively delivers high-quality sound effects on low frequencies. The driver has a common size of 10 inches which is a very popular option when you want to enjoy deeper sounds.

  • Frequency response: 50Hz-100Hz.
  • Dimensions, inch (HxWxD): 11×16.9×16.9.

The first things that catch your eye in this model are the shape and design. The TIC TFS50 is made in the form of a stone. Yes, you’ve read it right. The manufacturer offers three colors: Canyon (CN), Slate (SL), or White Granite. I personally liked this idea. It looks very unusual and original on the ground. I would also note that the TFS50 has a composite housing with a silicone seal, resistant to various weather conditions, with a frontal drainage system.

It is a passive omni-directional subwoofer speaker with 360° bass sound. Power handling: 125W RMS / 250W Peak. Stereo satellite speaker capability with built-in passive crossover system. Impedance: 8Ω/input (standard mode) or 4Ω/input (satellites mode). Frequency response: 40Hz – 200Hz (crossover @ 200Hz).

TIC TFS50 photo

As a passive subwoofer, this model requires an amplifier and does not accept a single LFE line (low-frequency effect) as input. With its built-in passive crossover, the TIC TFS50 is designed for standard stereo inputs and automatically separates the different audio frequency bands. It is also compatible with both standard and subwoofer amplifiers. It should be understood that using a dedicated subwoofer amplifier will improve sound quality but will reduce the satellite output capabilities. Although it is possible to connect DVC speakers to the TFS50, the manufacturer recommends using standard 8Ω speakers as satellites.

Key specs

  • Power (RMS), W: 250.
  • Driver size : 8.
  • Frequency response: 25Hz-200Hz.
  • Dimensions, inch (HxWxD): 14x11x21.


  • Unusual shape.
  • Several colors to choose from.
  • Sturdy enclosure resistant to various weather conditions.


  • To get real bass, you have to turn up the main volume a lot.

TIC GS50 – budget


If you need an all-weather subwoofer to bury it into the ground, then TIC GS50 will be able to help you. It is a nice model, which you are free to install everywhere outdoors. It has green housing made of ASB polypropylene that withstands various weather conditions. The satellite design enhances the range of sound, and it goes in all directions.

Inside, you receive 250W of power with an 8-inch driver, which enhances with omnidirectional sound technology. It allows users to enjoy music in all direction angles. One of the many benefits that you receive with TIC GS50 is the compatibility with various other devices. Passive inner crossover automatically separates several bands of audio frequency and improves the quality of sounds. The unit comes with two waterproof wire connectors if you plan to connect the subwoofer with other speakers. Devices with 8om impedance are better if you wish to receive higher sound quality.

Key specs

  • Power (RMS), W: 125.
  • Driver size : 8.
  • Frequency response: 25Hz-200Hz.
  • Dimensions, inch (HxWxD): 12.5×12.5×13.


  • Manual contains all information you need to properly install the subwoofer.
  • This subwoofer produces wonderful sound while buried in the ground.
  • Can be easily hidden in bushes and behind other plants.
  • The assembling of the subwoofer does not require a lot of time.


  • It does not have an in-built Bluetooth adapter.



I would like to introduce you to another bright representative of in-ground subwoofers – OSD GLS8. The main part of it is under the ground, and only the outdoor subwoofer speakers are visible from above. By the way, the open vent can be painted to look more organic to your landscape.

Unit dimensions: (L x H x D) 19.75″ x 28″ x 15.5″ and weight: 32 lbs. Frequency response: 8Hz-200Hz, power handling – 500 Watts, sensitivity: 84 dB, and impedance: 8 Ohms. And, of course, it is 360° omni-directional. As you can see, the GLS8 is quite powerful and efficient.

It is a passive subwoofer and needs an amplifier to power it. The manufacturer recommends the SMP-300, rated at 500 watts peak power and 250 watts continuous RMS power.

I advise placing the GLS8 20 feet away from the general listening area for optimum sound quality. It is also advisable to place the unit so that the vent is away from direct spray from sprinklers or the pool. Also, before burying the subwoofer, I would recommend putting gravel in the hole’s bottom for drainage and a flatter unit placement.

While it’s not going to shake the ground like a home theater sub, it adds a lot of warmth and the lower end that’s missing from most outdoor speakers. The sound was fantastic, and everything worked seamlessly with my iPhone. So the main objective of this model was excellent.

Key specs

  • Power (RMS), W: 500.
  • Driver size : 8.
  • Frequency response: 28Hz-200Hz.
  • Dimensions, inch (HxWxD): 19.7x28x15.5.


  • Sounds great.
  • This subwoofer really helps reproduce very deep notes.


  • Weak water resistance.


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.
