3 x DFF180-43PROs are used for the left, centre and right channels - using designs from the Donvig & Ljungberg collection. Rear channels are taken care of with the Diablo Monitors. No additional subwoofer is required in this system as they are built into the DFF180-43PRO This system leaves the room clean and elegant when not in use. This design is often used for living rooms, games rooms or anywhere where a permanent installation would prove undesirable. The screen disappears into the ceiling when not in use, dropping down to deliver a genuine cinematic experience when required. Performance of systems using this design can be every bit as good as a dedicated Spitfire cinema, but has the advantage of respecting the aesthetics of the space when not is use.
