Design and build


The Polk Audio PSW505 subwoofer’s design is very similar to many other budget speakers. It looks very stylish with a solid and durable MDF construction surrounded by a black layer.

The MDF helps the subwoofer provide distortion-free sounds that are also clear and accurate. Whether your room is on the larger or smaller side, the PSW505 would look good no matter what. Its combination of black color with wood veneer is very elegant and attractive.

Detachable cloth grilles

Detachable cloth grilles add to the appeal of the PSW505 subwoofer creating a well-sized oval on the front of the speakers.

This may not be unique to this model but I really like this particular design.

Control panel

Its control panel is located on the back of the subwoofer incorporating all necessary settings and controls. These are a little harder to reach compared to other models but you’ll soon get used to them.

A toggle switch allows you to run more subwoofers if required so you can have full surround sound. Talk about a cinematic experience! There are also options for an adjustable low pass crossover and phase switch from the subwoofer’s main volume control.

This means you can get the most out of your speakers and your sound. If that wasn’t enough, you can even adjust the voice volume to make it higher or lower than the background sounds. This makes voices easier and clearer to understand for a more enjoyable experience.

The PSW505 is essentially a very impressive subwoofer with an attractive design and built quality. Nonetheless, let’s take a look at the performance level this subwoofer has to offer.



At peak power, the Polk Audio PSW505 subwoofer reaches 460Watts while its basic power is 300Watts. It has a frequency range of 23-160Hz which is more than adequate for listening to music.

Its lower peak power is a little disappointing for some users but it more than makes up for this with an excellent bass level and its clear sound for distinguishing voices with a higher constant 300W power.

The subwoofer’s bass sound is powerful and distortion-free. If you like to watch action movies or big blockbusters, you will absolutely love the amazing rush that comes from these speakers.

It is engineered with a unique motor-like design with a longer suspension than most subwoofers offer. This design allows you to enjoy calmer and more peaceful melodies far more.

Magnetic shield

This subwoofer comes with a magnetic shield to prevent noise distortion or interference. This means you can place it near your television without having to worry about excess noise.

Nonetheless, I recommend you keep this subwoofer a little distance away from your television as the magnetic shielding isn’t always entirely effective.

Automatic feature

The Polk Audio PSW505 subwoofer comes with a highly convenient automatic feature that switches the subwoofer on whenever a sound signal is picked up or present.

If there are no sound signals for 15 minutes, the subwoofer automatically turns back off. Not only is this very useful but it is also extremely efficient.

You could save money on your energy bills over time thanks to this clever feature. If you’re like me, anything that saves money down the line is worth it!


The Polk Audio PSW505 subwoofer comes under the category of budget subwoofers. This isn’t to say it doesn’t offer good quality though!

There are regular sales which bring the price down from its usual reasonable standing.

When this price is decreased, the PSW505 subwoofer has to be one of the best models you can get for that kind of money.

It offers nearly everything you look for in good quality subwoofers such as good noise-canceling features, an excellent frequency range, and larger speaker diameters than most of its competitors.

With its stylish design, the PSW505 is a superb subwoofer at an even better price. If you can wait, I recommend you hang on for the discounts to come in again.

Measurements and weight

The Polk Audio PSW505 subwoofer measures 16 x 15 x 18-inches and should fit comfortably in most living spaces.

Its weight of 48-pounds means the whole unit is pretty easy to move around and fit into certain spaces.

Warranty and support

The Polk Audio PSW505 subwoofer comes with an instruction manual to get you started. This will inform you of the whole process and any necessary tips on getting the most out of the PSW505.

It comes with an online registration card so you can access support at any time if required. There is a 3-year warranty for all electrical parts (the amp) and a 5-year warranty for non-electronic components.

If you have any problems with the subwoofer, get in touch with the manufacturer and they will provide you with all the support you need. This kind of warranty is a leader in this industry.

In Summary

It’s hard to ignore how much of an absolute steal this subwoofer is when you compare it with similar models on the market today.

It does lack some quality when it comes to low-frequency sounds as they can become distorted but this shouldn’t affect your movie-watching experience.

Although it may not have the widest frequency range, the Polk Audio PSW505 makes up for this with a provision of deep bass for clear and pleasing melodies.

For its price, there isn’t much better than this PSW505 subwoofer. It more than makes up for what it lacks with outstanding features like the magnetic shielding and automatic on/off component.

Its simplistic look and design may not be to everyone’s taste but I believe it adds to the overall charm and the fact it will look good in most spaces effortlessly is a great selling point!

Overall, the Polk Audio PSW505 is an excellent choice if you are looking for a deep bass yet high-powered speaker.
