(Springfield, IL) Legacy Audio introduces the new doubleHelix audio system for state-of-the-art cinemas and large screen theaters. The system was recently installed at the Peoria Riverfront Museum in Peoria, Illinois which is scheduled to open this week. The Peoria Riverfront Museum’s two-hundred seat Giant Screen Digital Theater boasts a 70 x 52 ft screen and a 4k projector (4096 x 2160 pixels) that beams through a custom glass projectionist window that measures approximately 10 feet

The Peoria Riverfront Museum’s two-hundred seat Giant Screen Digital Theater boasts a 70 x 52 ft screen and a 4k projector (4096 x 2160 pixels) that beams through a custom glass projectionist window that measures approximately 10 feet across. “The theater represents a unique opportunity to pull out all the stops in the audio and video presentation,” says Zdi, Inc.® CEO, Aaron McArdle. Zdi, Inc. is the system design integrator for the museum. Global Immersion, a UK company, is providing all the video solutions.

Let's learn about the audio system...

The audio system reaches beyond conventional theaters, and is designed by sound engineer Bill Dudleston of Legacy Audio. It will provide up to 20 steerable sound locations and will be powered by 42 channels of amplification offering 14,000 watts. The system will utilize Dirac room compensating software hosted by the Datasat AP20 digital processor, which compensates for room reflections and provides system crossover and equalization.

The doubleHelix technology was first utilized in a custom system built for legendary record producer L.A. Reid of Epic Records, X-Factor, Arista, UMG fame. The loudspeaker system is unique to this theater installation. It features five 3 x 5 x 1.5 ft Legacy doubleHelix splayed along the seventy foot long platform, located some 30 feet above the floor. The Giant Screen Digital Theater will also exploit 14 surround loudspeakers and an overhead loudspeaker in the shape of an inverted, truncated pyramid that projects sound to all viewers. This speaker will provide continuity in ambience and add drama to flyover effects.

Moving on to the technology...

Evolving cinema technologies from studios such as Dreamworks® and Pixar® are raising the expectations of theater sound. Reacting to this challenge, companies such as Legacy Audio are now providing systems with more channels of playback and more convincing immersion experience.

According to Legacy Audio President and Chief Designer, Bill Dudleston, “The doubleHelix is unique in that it offers wideband directivity control. The large cabinets are dipolar in nature (open to the sides) which helps to focus the lower midrange and upper bass range, and provide a longer acoustic throw. This improves intelligibility and allows the off-center seated listener to hear the more distant channels adequately. The special driver array also reduces undesirable bass droning and overhang.”

Each of the five doubleHelix in the front of the theater employs four internal 500 watt ICEpower® amplifiers to drive the digitally steered channels. Included in the system are fourteen identical side and rear channel speakers and an exclusive centrally located overhead channel. The overhead speaker is in the shape of a truncated inverted pyramid with separate speaker components on each of the facets. Total system power in the Peoria Riverfront Museum exceeds 14 kilowatts and meets stringent efficiency requirements.

You’ll find the industrious city of Peoria amidst the prairies of central Illinois – about 150 miles north of where the majestic Illinois and Missouri rivers converge on the great Mississippi. The riverfront city is the international home of Caterpillar Inc., a significant contributor to the P.R.M. project, which broke ground in September of 2010.

The quality of the sound and picture goes up as the quality of the modern entertainment being played through said system goes down. Funny that.

So, I'm assuming that with a digital projector and no 70mm/15 system at a museum... this is what you would call a LieMax theater. The sound is probably phenomenal, but the visual impact is less than ideal.
