## Description

The Polk React Series is the newest series within Polk’s highly successful sound bar lineup, designed by legendary speaker designers who worked towards the aim of developing sound systems that could work with virtually any Television setup. Belonging to the same lineage as the Polk React Sound Bar, the React Subwoofer, a 7” long-throw wireless subwoofer with an unassuming design may seamlessly blend into the room but it sure can be heard loud and clear, no matter the placement. Perfectly tuned to add that extra oomph to Polk React Sound Bar, this powerful subwoofer engineered for a long reach bass impact and self-regulating Bass Adjust EQ accommodates and balances the additional bass flawlessly by automatically adjusting the soundbar’s setting. A welcome addition to any home theater and entertaining system. Complete the React series and build a 5.1 channel setup by pairing the soundbar and sub with the SR2 Surround Speakers for an immersive, unforgettable home theater experience from this small yet powerful sound system.

Review: Great sounding soundbar with Alexa built in - I previously tried a different brand sound bar with Alexa that was less expensive and had issues connecting to network. I use a separate vlan for IoT devices and suspect that was the issue, but the bar may have been defective. Either way, this one connected through the Alexa app instantly and works perfect. Connected to TV at first without the subwoofer and was really impressed by the sound from this bar. Great sound and surprising bass overall for as small and inexpensive as it is. Connecting to the sub took maybe 30 seconds and it added a lot on the low end. Alexa works just like any of my other echos, listens well and responds accurately. When I change sound mode she speaks the mode but it is not loud and looks like they fixed that issue. Sound is pretty good for a sound bar, definitely built for vocals. Lots of mids which is not the best for listening to music if you are looking for audiophile quality but I have no complaints. TV dialog is much clearer than TV speakers and the sub adds great bass extension. Remote is nice, recessed buttons are a bit odd but it works good and doesn't feel cheap. Only wish I had was there was better settings control in the app that would match the ability of a regular echo. Limited but not limiting. Overall highly recommend and would definitely purchase again.
Review: Lo recomiendo - Esta genial y mas si le agregas el subwoofer y las bocinas extras inalámbricas al principio se subia solo el volumen al máximo sin yo moverla a nada me imagino que una vez que se actualiza la alexa interna ya no me dio ese problema pero si la recomiendo ampliamente
