The Roth Sub Zero III has been designed to provide high definition for your TV. It has HDMI (2 in/1 Out, ARC enabled), Optical, Bluetooth and Analogue inputs. This means the Sub Zero III will connect easily to any TV or audio source – even wirelessly from your laptop, mobile phone or tablet. So lots of versatility.

There is no need for a separate subwoofer as the Sub Zero III has two built-in Ultra-Bass passive drivers, 2 bass drivers and 2 full range drivers, allowing full frequency range audio in a single discrete unit.

The Roth Audio Designed to perform in any room large or small. It features the Roth MA DSP sound processor, which provides a powerful sounding home cinema experience. With the additional modes, you can select between movie, music and voice. Sometimes, you don’t need lots of bass! Considering its size, the sound bar rocks and makes a huge difference over the built in TV speakers.

The Sub Zero III can be wall or table mounted. In the box is a right angle HDMI adapter which is handy as the connections end up fairly close to the wall or table top. It would have been a nice touch if a HDMI cable was included.
