Signa Solo is Polk Audio's most affordable soundbar yet

Signa Solo seems to have its sights trained on the class-leading JBL Boost TV (£170), but Polk hopes it can make an impression in the budget market thanks, in part, to its own technologies.

The Signa Solo features Polk's SDA digital surround and Voice Adjust technologies, the latter of which lets you manually fine-tune voice levels. There's also SmartBar, which supposedly makes the soundbar automatically controllable with all TV remotes, with no programming necessary.

More typically for a soundbar, it features Dolby Digital decoding, an optical input for connecting to a TV and built-in Bluetooth for music streaming from a smartphone, tablet or portable music player.

To keep things compact, Polk has built bass ports into the bar's four 2.5in full-range drivers, which it says eliminates the need for an external subwoofer.
