As its name would suggest, the Signa Solo soundbar doesn’t include an external subwoofer. In fact, according to Polk the Signa doesn’t require an external sub thanks to its 4-driver array and dual bass ports. Connection choices on the bar are a little slim. The unit has 1 optical input and a single 3.5 mm AUX input.
The Signa Solo includes Polk’s VoiceAdjust tech to boost dialogue. It also supports Dolby Digital surround decoding and has built-in Bluetooth so you can send music wirelessly to it from a smartphone or tablet. Polk went the extra mile to make the Solo as easy as possible to setup. In fact, the bar includes a feature called SmartBar. With this, the Signa Solo is able to automatically work with all TV remotes. No programming necessary.”
