A dedicated home cinema is a wonderful luxury that most people are envious of but it is easily achievable. If you have a spare room, this could be an unused garage or loft space then why not turn it in to a sanctuary of film. With 4K projectors now becoming readily available you can have a better picture than your local commercial cinema and with high end speakers from the likes of Origin Acoustics, Kef, or ProAudio Technology powered by amplification from Onkyo, Marantz or Denon then the sound can literally shake the room.
A Home Cinema is a fantastic addition to any home and the only limit is your imagination and budget.
To start with why not add a discreet surround sound system to an existing TV in the lounge. When properly installed and setup with a single remote control to control everything instead of a coffee table full.
If the space exists you can then always upgrade to a dedicated home cinema.
