Polk React soundbar review: What do you get for the money? The Polk React soundbar will set you back £249. That gets you the soundbar, HDMI and optical cables for connecting to your TV, a remote control with two AAA batteries included and a pair of wall mounting spacers. Adding a pair of Polk SR2 rear speakers to the mix raises the price to £408, while a soundbar and subwoofer combination is available for £428. For a true surround sound experience, you’ll want the full package, which includes both the rear speakers and subwoofer for £587. The rear speakers and sub can be bought separately at a later date if you’re ready to splash that kind of cash right away.
