Design and Setup

The package essentially includes the basic soundbar and a subwoofer. The central unit is portable and lightweight, which makes its placement stress-free even if you suffer from very limited space. The included subwoofer has a rather small size measuring 6.72″x13.4″ x 12.2″ and weighing eleven pounds. You can effortlessly find a little spot for these on your floor without any fuss.

The subwoofer has a modest design with soft curves and is made of plastic material. The S2 is the type of device that looks simple yet elegant. Its front area is coated fully with a black grille that expands to the head of the device casing it as well. At the top, five circular buttons are procuring the most fundamental functions.

Most soundbars offer some level of visual demonstration to give some visual acknowledgment of their commands; however, Polk utilizes some LED lights in the middle of the device’s front to indicate certain actions: what input is in use, if Bluetooth is on, or the user is modifying the audio.

On the back is a small number of connectors and some unique slot spaces to mount it, and its smart construction makes handling this device very manageable. Its lightweight aspect allows for quick carrying and mounting. Behind the grille are two elliptical drivers set in both directions, with a handful of one-inch tweeters in the middle.

The subwoofer uses a 5.25″ driver coated with a non-detachable grille. The product has a clear-cut design to make things as uncomplicated for you as possible.

The product is quick to set up and ready to go right out of the box. There are no demanding requirements or connections necessary. Once you connect it to your TV and via the HDMI port, the soundbar and subwoofer are pre-paired from the factory for instant connectivity.

Still, if you encounter a connection problem, a press of the button on the back of the subwoofer while also pressing the Bluetooth and VOL + simultaneously on the remote will assure the two will pair again. After that, turn on the device, and you are ready to go. That is all there is to it!


Polk Audio manages to bring some improvements compared to the previous models by putting in an HDMI port with ARC functionality. HDMI is the common generally utilized port in current home theatre devices, and it was missing from the previous models, so this makes for quite a development. Then comes a standard 3.5mm slot.

Another mini-jack is situated on the side and contains the power cable. There is also a USB slot on the lowermost area of the soundbar. The S2 also features a Bluetooth connectivity option.

Control Options

With a reasonably priced device like this, it offers minimal and fundamental control options, making this product very simple. The controls on the topmost area of the body allow a swift way of getting the most basic options, and the buttons have the conventional rubber feeling to them.

They are solid and do require some hard pressing. At the uppermost area comes the power button along with mute keys, while below them are three buttons for choosing an input option.

Two big buttons below these are to control the audio and bass. Next, come the buttons dedicated to the multiple modes users can choose depending on what you wish to put on, like music or movies, and night mode is enabled when you do not want to be a nuisance for other family members. Its remote is relatively small, you can hold it easily, and you can press every button with a single handgrip since its design is fundamental.

There are not many options on the device, so the amount of buttons required on the remote is very limited. The S2 is HDMI-CEC enabled, which means that when you connect it to your TV through the HDMI port, you can opt for the TV remote to control the soundbar.
