Transform the sound of your flatscreen TV, with the HDMI-equipped Roth Sub Zero III soundbar.

Connect with HDMI

Featuring twin HDMI inputs and an HDMI output, the Roth Sub Zero III connects to the rest of your system in the best way possible. HDMI is a convenient connection that offers a digital signal for both sound and vision giving you the highest quality for both. With ARC (Audio Return Channel) you can connect to your TV with just one cable (the picture travels to the TV and the sound from the TV's tuner back to the soundbar).

Bluetooth music streaming with aptX
In addition to making your TV sound great, this Roth soundbar also offers easy Bluetooth music streaming. With this, you can stream music from your smartphone, tablet or Bluetooth-equipped laptop or desktop computer, accessing your music library or a music streaming service such as Spotify or Apple Music. By using the high quality the aptX format, the sound is the best possible from Bluetooth.

Power up
With power from the four built-in, digital amplifiers up by 50% from the Sub Zero 2, to 90 Watts, the Sub Zero 3 offers an even more room-filling sound. Designed for low distortion, the Sub Zero III can be turned up to high volume levels without the distortion and harshness that you'd find with TV speakers. Passive bass drivers give a deep, rich bass that built-in TV speakers simply can't recreate. Roth DSP sound processing also gives an enveloping sound that you wouldn't credit from a compact speaker cabinet.

Easy to use and flexible positioning
With a choice of analogue or digital optical inputs, the Sub Zero III works just as well with your components that don't have HDMI. At just 8cm deep it's easy and unobtrusive to position, while the included wall mount kit gives more positioning options.

Bring the sound from your TV to life and free the music from your mobile in one, with the versatile Roth Sub Zero III.

ROTH SUB ZERO III is rated 4.2 out of 5 by 13.
Rated 1 out of 5 by from Very poor value for money. Firstly, when I got home, the box did not contain the correct connection lead. When I returned to the shop I was then charged for acquiring the correct lead. When I got it working, it turned itself off repeatedly while I was listening to it. The final straw was that the sound quality did not reflect the £140 spent - so I returned it and got my money back and purchased a Samsung soundbar for the same price which was vastly superior in quality.

Rated 3 out of 5 by from Good sound but design flaws This is a good looking soundbar with a high quality sound. Unfortunately my soundbar automatically turned the device off every 45 minutes which was very annoying. Roth technical support were very helpful but we're unable to solve the problem as it seems it is a design feature of the device. So be warned, if you set the volume to less than 50% on the soundbar (which is fairly loud) the device may periodically shut down.

Rated 5 out of 5 by from great product delivering a great performance yet again the staff at Richer in Brighton stepped up to the mark with sound (no intended pun) and impartial advice to me (a muppet!!).. They are spot on. Go there - you will not be disappointed.

Rated 2 out of 5 by from Just good enough, cheaper elsewhere, near useless for table top use Decent sound when the volume is half way up or more. 3 sound options but the voice is useless/ terrible. Movie or music mode ok. Lots of options to connect - HDMI, Bluetooth, optical etc but the really annoying thing is that the small recess where they are is on the bottom! Fine if this is wall mounted but a real pain otherwise. It's used in our bedroom so not always on otherwise I would have taken it back. Richer Sounds are my go-to place for tv and audio, but after buying this I found everywhere else sold it a bit cheaper....

Rated 5 out of 5 by from Great Piece of Kit My TV speakers just weren't up to scratch so I needed a cheap quality sounder. Got to say, this ticked all the right boxes. Price - Bargain!!, connectivity - superb. Style, very sleek. If I had to suggest any improvements, it would be that the remote is quite basic and the reaction time between selecting a function such as "volume +" and it actually taking effect is a little slow. But for the money, this is a sound buy. I'm delighted!! Massive thanks to Richer Sounds in Chester. Got to hand it to these guys, they know their stuff and the service is spot on. I have just spent about £3k with these guys and I can't think of a better place to go for my audio. Well done guys!!!!
