We've said it before and we'll say it again, a soundbar is the single easiest way of improving your TV's sound, and with the soundbar format now being embraced by everyone in the industry there's a huge amount of choice available to consumers. Of course, as with anything audio-related, you can spend upwards of thousands on a soundbar such as Samsung's phenomenal HW-K950, but at the more budget end of the market you also have the likes of Roth Audio providing surprisingly capable soundbars that won't break the bank. The Roth Audio Sub Zero III doesn't offer the most refined sound out of any soundbar we've ever listened to, but what it does offer is a solid upgrade to your TV's sound that manages to bring a health boost to bass levels whilst preserving the detail in the sound.
