"The world’s best cinema speaker system is coming to your front room!"

The most common type of surround sound that people actually use in their homes or hear at the cinema is 5.1, with three speakers at the front, two at the rear, and a subwoofer that’s dedicated to bass effects and doesn’t go in a particular position. More recently some cinemas and many home cinema amplifiers have started supporting 7.1, which adds an extra pair of speakers at the rear for more realistic effects.

Dolby Atmos is significantly more advanced than either of these systems, using up to 64 speaker channels spread evenly throughout the auditorium, including along the ceiling. This gives the filmmakers the ability to direct sound with pin-point accuracy into the room. It’s an absolutely stunning experience, far in excess of whatever you’ve heard in a cinema before. If you can get to a cinema that’s got it, it’s definitely worth seeing something in the format as soon as you can.

With companies like Sky, BT Sport and Netflix now offering their content with Dolby Atmos capabilities, experiencing the complete immersion of this technology at home is a lot easier than you may think.

Simply connect compatible speakers to be transported into a new world of entertainment. Dolby really have thought about every single person when they created this revolutionary format. Whether you wish to use upwards-firing speakers or are able to utilise in-ceiling speakers, you will experience 360° sound like never before.

The flexibility of Dolby Atmos means the possibilities are almost endless. A system usually starts with a centre and two stereo speakers, a subwoofer and rear speakers. The unique difference with Dolby Atmos is sound from above. Drivers facing upwards built into existing speakers, or separate speakers adjacent to them, reflect sound from the ceiling to create unbelievable sound dispersion. For the ultimate experience, in-ceiling speakers expertly place the action where it belongs.

Whereas many people will be familiar with 5.1 – which creates surround sound from 5 speakers and 1 subwoofer, the extra speakers Dolby Atmos uses to fire sound downwards are added to the end – 5.1.2 uses 2 speakers for height, whilst 5.1.4 uses 4 extra speakers for the ultimate in reference quality.
