SIGNATURE ELITE ES30

The Polk ES30 combines high-fidelity sound quality with a low price. It has a built-in remote control and comes with a 5-year warranty. The ES30 is part of the Signature Elite series, which means it's compatible with DTS:X and Dolby Atmos. Because it's compatible with these formats, it provides realistic sound no matter where you're sitting.
The Polk Audio ES30 comes with a bass reflex type cabinet with a wood-grain vinyl finish. This type of loudspeaker uses a port cut into the cabinet, making it more effective than a Sealed design. Its four self-adhesive rubber feet also help isolate vibrations at specific frequencies.
