I have built a dedicated cinema room within my garden. It has been fully sound proofed and offers a World Class Cinema Experience, better than anything you will experience within a commercial setting.
It has 15 speakers and 4 subwoofers, with a total of over 8000 watts of power. 4k Laser Projector with a 120" screen. Fully blacked out so the only viewable item within the room when a movie is playing is the screen, literally everything else just looks like black space.
The build has been featured in Home Cinema Choice Magazine. I have also hosted "Forum Open Days" to showcase the room to other members of AVForums.
Added to the sound and viewing, it also has "tactile chairs" which vibrate when the relevant content is played on screen.
You can also watch sports, play games, surf the net from within the room.
My photos will never do the room justice, it needs to be seen (and heard) to fully appreciate.
I am an official Ambassador for the Speakers and Subwoofers in my room which is a company called Arendal Sound. I have no affiliation to them, the benefits of being an Ambassador are very small, basically my room is featured as a showcase on their website, due to the level of performance the room can deliver.
