The project

The goal was simple to say and hard to do well: build the ultimate room for movie night.

That meant sound that moves all around and above you, a picture big enough to feel like a real cinema, and an atmosphere that makes the room an experience before the movie even starts.

Sound you can feel overhead

We designed a 5.2.4 Dolby Atmos layout with Episode Signature 7 Series speakers throughout. Matched LCR speakers handle the front left, center and right channels, Signature 7 Point speakers in the ceiling carry the four Atmos height channels, and Signature 7 surrounds cover the rear.

Dual subwoofers fill in the low end, and a Marantz Cinema 50 AV receiver powers and processes the whole system.

A true cinema picture

Up front, a Sony 4K laser projector fills a 145-inch Dragonfly screen. Laser projection gives a bright, sharp, color-accurate picture with no lamp to replace, so it stays consistent for years.

The finishing touches

We topped the room off with a fiber-optic star ceiling that glows over the seats. Behind the scenes, a large AV rack holds the theater electronics plus the home's whole-house audio and data network, and an LED strip makes the rack as good-looking as it is organized.

The result

A private cinema that looks and sounds incredible, built on gear chosen to perform together and to last.

5.2.4Ear level

The "5": matched Episode Signature 7 LCRs across the front, plus Signature 7 surrounds at the rear. Dialog stays locked to the screen.

The ".2": two subwoofers in the front corners. Two subs even out the bass across every seat, so the low end hits the same wherever you sit.

The ".4": four Signature 7 Point speakers in the ceiling carry the Atmos height channels, so a helicopter can fly right over your head.

The Sony 4K laser projector lights the 145-inch Dragonfly screen, the room goes dark, and the star ceiling comes up overhead.
