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.

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  • It is an outdated model, and on the market, you can find better subwoofers in quality and price.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.

OSD FORZA 10 – best overall


OSD Audio Store constantly develops new stereo models to satisfy customers. Unless outdated speakers, FORZA can become your best outdoor subwoofer. It easily deals with severe weather. This unit has an IP66 rating. It allows you not to worry about it during dusty, rainy, and frosty weather.

FORZA 10 has a simple but pleasant design. It looks like a garden stool or a footstool, which makes it fit into the garden landscape. Its gray color is quite inconspicuous, and you can hide it behind bushes or under a table. It’s up to you to set it on a hard surface or place it on the ground. The Forza 10 subwoofer is compatible with both options, but on a hard surface, I noticed vibrations, and I recommend putting it in the ground or decorative pebbles. There are special bent legs for this purpose; in this case, they are very stable. There is also a mounting option (which comes with the kit). You can nail the garden to the surface, which is the surest way to avoid vibrations.

After bad weather, you will not have difficulties in cleaning it. Even when the sun is shining, it resists UV. Moreover, you do not need to worry about leaving this subwoofer outside for a night. It has the antitheft feature. The built-in eyebolt to anchor will keep your device in one place.

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. If you want to receive an even better response, you should place it on hard ground or on a surface. As it is wireless, you will not have to manually turn it off and on. Moreover, when it is in-ground, you can easily use a subwoofer without difficulties.

Forza 10 is a down-side firing model. It means that sound goes downwards and hits the surface. As a result, you receive more colorful bass, which is properly reinforced to enjoy music at full.

The benefits of owning an OSD Forza 10 are quite obvious. It’s made from robust materials that can withstand climatic conditions, including wind, dust, and rain (IP66 rating); it looks great in a garden interior and sounds powerful, loud, and bright even in outdoor conditions. And for the optimal price/quality combination in my chart, it’s a well-deserved first place. Since its design allows you to dig it a bit into the ground or garden pebbles, you’d better do just that. After all, in this case, you will avoid unwanted vibrations. The brand’s reputation is solid, and Forza 10 proves it with its compatibility with various speakers, amplifiers, and DACs.

Key specs
  • Power (RMS), W: 300.
  • Driver size : 10.
  • Frequency response: 50Hz-300Hz.
  • Dimensions, inch (HxWxD): 19.9×19.2×15.
  • It easily pairs with various speakers, amplifiers, and DACs.
  • The subwoofer is made of reliable materials to serve for many years and withstand various weather conditions.
  • It can be installed over and under the ground.
  • On hard surfaces, it vibrates what causes too much buzz sound.

Polk Audio Atrium SUB 100 – premium

Polk Audio Atrium SUB 100

It is hot, even at night temperature hardly cools down and you are planning a party on your terrace and by the pool? With the Atrium series, Polk offers weatherproof outdoor speakers that defy rain, wind, UV radiation, and fog. You can paint the Atrium SUB 100 according to your furnishing style and use it as a side table or plant stand.

The design of the Polk Audio subwoofer actually does not differ from the leader of the rating OSD Forza 10. It looks like a garden stool and is available in two colors (orange and gray). But its main advantage is that the body can be colored to your taste. Can you imagine that? That’s cool, in my opinion. The IP68 rating is even higher than the Forza 10. It can also be placed simply on the floor or dug into the ground (the feet on the bottom are slightly bent). Some connectors allow you to screw the sub to a wooden floor or even a wall. It’s housed in a molded and sealed enclosure with perfect acoustics and IPX66 marine-approved certification, ensuring you’ll enjoy years of unique weather resistance and outdoor performance. The atrium is built for the outdoors.

Polk Audio Atrium SUB 100 sound quality

With a combination of powerful bass and robust weatherproofing, you can hear bass outside or in the transition areas of your house as you normally only hear it inside. This underground subwoofer is the perfect addition to a set of Sat300s and gives the system the fully dynamic reproduction of a top-class audio system. Paint it so that it fits better in your conservatory or pool. The Sub100 offers real bass fun, and it will be the focus of your garden parties!

The included cover protects the subwoofer and ensures a distance from the ground in the outdoor environment. It can be perfectly integrated. Sub100 housing can be painted to perfectly match your facility. The resin impregnated with paint will never fade and is a perfect match for your outdoor furniture. The massive, 10-inch long-throw Dynamic Balance driver technology prevents driver distortion for deeper, clearer bass even at higher volumes.

When we are talking about premium equipment (and this model costs twice as much as Forza 10), of course, first of all, we are talking about quality. The power output is lower than the winner (200 watts, not 300 watts), but the bass response is excellent. So, I can’t say that the volume will blow you away. But the quality of the materials, the ability to paint the cabinet to your liking, the IP68 rating, and the fact that the speaker doesn’t bounce even if you just put it on the floor (16.75 pounds) are what you’re overpaying for. Is it worth it? Each of you will answer in your own way. In my opinion, when it comes to sound quality, you shouldn’t skimp, especially when discussing years of excellent service.

Key specs
  • Power (RMS), W: 200.
  • Driver size : 10.
  • Frequency response: 50Hz-100Hz.
  • Dimensions, inch (HxWxD): 11×16.9×16.9.
  • It is made of sturdy materials to serve for many years.
  • The color of the case can be painted according to your preference.
  • Simple installation.
  • Max volume is not loud.



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 sound quality

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.

The TIC GS50 model also looks similar to a garden stool and has two colors (black and dark green). But by its appearance, you can immediately understand that the sub is inexpensive. The plastic looks plain, although it is positioned by the manufacturer as all-weather and shockproof (ABS), but the IP rating is not specified. Nevertheless, both connectors and cables are insulated. The parts proved to be quite durable in testing, but true durability can’t be tested with a week-long test. The subwoofer is a bit lightweight, so I recommend digging in when installing it in the garden.

TIC GS50 sound quality

Inside, you receive 250W of power (peak , not RPM) with an 8-inch driver, which enhances with omnidirectional sound technology. It allows users to enjoy music from 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.

So, the TIC GS50 is a budget subwoofer costing half as much as the leader of the OSD Forza 10 selection. Is it good? Within its price range, it is. It puts out 125 watts of power (250 at peak, but you can’t always use it). It’s rugged and has connector and cable insulation, as a street sub should. But it’s quieter than the more expensive models, looks simpler, and you still have to attach it to an amplifier (extra cost) since it’s passive.

Nevertheless, for its money, it gets the job done. It sounds very decent, separating the audio frequency bands well, especially if you use a dedicated sub-equipment rather than a regular amplifier. You will lose the satellite input capabilities, though. I’d call it a pretty good, inexpensive entertainment for music in your garden.

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.

OSD GLS8 sound quality

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.
