Amazon Fire TV Soundbar Plus with subwoofer and surround sound speakers (newest model), 5.1 channel, Dolby Atmos, clear dialogue

Get a receiver and speaker package. Something like the Yamaha RX-V4A receiver and DefTech ProCinema 6D would be a good starter setup and give you a superior experience to just about any soundbar. If you really want a soundbar then consider the BRAVIA Theater System 6 or as a more budget choice the Fire TV Soundbar Plus with Subwoofer.
