Polk Command Bar

Hello, everybody, I am going to introduce, here is the Command Bar.
Whenever I watched TV, I wanted better sound, easier and more comfortable speakers.
The sound bar meets all my requirements.
Connect 4K and HD TVs to listen to high-quality music, and have a wireless subwoofer to entertain my ears with grand music.
Also, Amazon Alexa is built in so I can adjust volume or device by voice, and listen to audio book or music.
It is said that I can also connect to Amazon Fire TV and set the alarm.
This product is essential for our house, I think we can hear better sound quality comfortably through this product.
