The Polk Audio PSW505 has a cabinet made of MDF, laminated black with a one-inch front baffle. The MDF’s function is to eliminate the distortion and produce clear and accurate sounds.

The dimensions are 16.1 x 15.1 x 18.1 inches, while the weight is 48 pounds.

The cabinet itself is solid and well constructed, which is not the case for the detachable curved cloth grille that creates an oval on the speaker’s front. The combination of black and wood veneer makes the subwoofer attractive and fitting for any room.

The cabinet has four plastic feet, which doesn’t help much around sliding the speaker at high volumes if placed on a smooth surface.

There is a twelve-inch front-firing speaker created from a high excursion polymer composite cone.

So as you can understand from the description, it is not the most beautiful speaker ever, but it is not ugly either. It is just kind of simple.

The control panel is on the back of the subwoofer and has all the basic settings and controls. The toggle switch is there to provide you a complete surround sound if needed — an authentic cinematic experience.

An adjustable low pass crossover option is available, and a phase switch from the central volume control allowing you to get the maximum out of the speaker and sound. If you want to make the vocals more precise and more understandable, you can adjust the voice volume higher or lower than the background sounds.

The Polk Audio PSW505 has an effortless setup; plug-in power, connect it to the receiver, and you are good to go. All you have to do is find the right spot for the subwoofer and make sure it has enough wall clearance.

The RMS power (root mean square, the amount of energy a subwoofer can handle continuously for extended periods, as compared o the maximum wattage it can cope with in brief bursts) of PSW505 is 300 watts, 460 watts dynamic peak, with a frequency range of 23-160 Hz.

The sensitivity is 85 dB. Impedance is 4 ohms.

This subwoofer has a magnetic shield that prevents distortion and interference so that you can place it near the TV without any worries.

There is an exciting feature of the Polk Audio PSW505 that switches the subwoofer whenever there is a sound signal present. If the signal is gone for 15 min, then the subwoofer automatically goes off. This feature is very convenient and power efficient.

When you purchase the PSW505, you get an online registration card, so you can access support when needed. The company gives a three-year warranty for the electrical parts and a five-year warranty for the non-electronic components.

Sound quality

Polk has done a great job by creating a balanced subwoofer such as PSW505. The massive twelve-inch woofer dives deep into the 20 Hz range and produces lows that are rich and well-rounded at all volumes, sounding huge and without distortions.

Polk’s slot load venting design serves to get rid of the pressure from the chassis, reduce the turbulence, and deliver a fast response. That way, the bass is tight, precise, and gut punchy.

In case you notice port noise, it is usually at high volumes when listening to music and does not seem to be an issue when watching movies. The same happens with the lowest frequencies, getting a bit muddy at times.

The subwoofer Polk Audio PSW505 has mighty bass, capable of shaking the whole room, which comes as an excellent bonus when watching an intense movie scene. Even at fifty percent volume, PSW505 has an impressive impact.


The Polk Audio PSW505 is a budget subwoofer, and if you find it on regular sales, you shouldn’t miss the chance to buy it.

Nothing is perfect, so even though it lacks some quality when producing low-frequency sounds, it doesn’t make a big difference when watching movies. The frequency range is not the widest, but yet the bass is straightforward and pleasing.

You get a great subwoofer with fantastic features for the money you pay, especially if you manage to get it during sales.
