This ultra-low profile, dialogue enhancing, 3.1 sound bar system creates a broad, enveloping soundstage for TV, movies, music and sports. The SB1 Plus lets you expand to a true 5.1 home theatre surround system with its built-in wireless surround sound speaker technology (requires a Fall 2016 software update). Never miss a word of dialogue with Polk’s proprietary and exclusive voice adjust technology. The SB1 Plus also features Dolby Digital surround sound, a powerful 8” wireless subwoofer, and is compatible with most TVs, cable boxes and their respective remotes. For the music lover, wirelessly stream music from your Smartphone, tablet or computer with the Wi-Fi enabled SB1 Plus via the Polk Omni app, or uses the included Bluetooth adapter for Bluetooth streaming.
