This story could have easily just been about the Theo Kalomirakis-designed Art Deco home cinema. Or it could have focused instead on the jawdropping one-of-a-kind entertainment area, with its discreet stage, ability to accommodate 250 guests, and epic views of Sydney Harbor. But there turned out to be an even bigger—though not quite as showy and obvious—story to be told, about how these kinds of high-end spaces have become so elaborate and flexible and the trends and technologies influencing and supporting them are evolving so quickly, that we’re now being presented with an unprecedented array of opportunities—but also the continual challenge of staying ahead of the curve. 

Every home cinema is a completely custom and unique machine. And the open-floorplan multi-use entertainment areas that are beginning to supplant dedicated theater rooms (like the one profiled in “Achieving Serenity”) are even larger and more complex machines that have to be able to handle a wider and wider variety of tasks. You don’t need to be a techie or have any interest in what’s going on under the hood to realize that creating something like that and keeping it functioning optimally means relying on massive processing power. The key thing to remember is that these systems are basically one-off computers and subject to all the thousand shocks and upgrades our digital brethren are heir to.  

Because of that, this is also a story about not the visible but the invisible. As spectacular as these rooms are, they’re literally useless unless someone keeps a constant and careful eye on all manner of things that are never seen by their users. Acoustical designer Steve Haas has developed a reputation as a master of that unseen realm, one of a you-can-count-‘em-on-the-fingers-of-one-handful of people who know how to not just tame but maximize these intricate, individually crafted mechanisms so they can achieve and maintain peak performance. The portfolio of his company, SH Acoustics, extends well beyond private residences to museum and commercial venues as well, and Haas found himself having to draw extensively on that broader pool of knowledge in order to make this Australian homeowner’s exceptional mandate a reality.

A VERSATILE PERFORMER

The seven levels that constitute this 55,000-square-foot residence—let’s call it the Sydney Home—rest terraced in a rock face overlooking the harbor, with the iconic bridge and opera house prominent in the dioramic views from its primary living spaces and numerous terraces. It shouldn’t be a surprise to hear that a home of this caliber would hold a theater from a premier designer like Kalomirakis, nor that Haas, who has collaborated on some of Theo’s most ambitious efforts (including the legendary Paradiso) should have been called in to handle the acoustic and audio chores. 

The entertainment area, with its  spacious bar & lounge area and terrace with epic views of Sydney Harbor, can comfortably accommodate 250 guests

The stage area, with the main speakers hidden behind the fabric at the top of the proscenium. Steve Haas took the client to the Steinway showroom in New York to help him select the Model B grand piano.

“Once I had some dialogue with the client, we realized there was a need to have me consult on other keys areas of the home,” says Haas, “especially what they call the Level 1 entertainment space.” It’s not unusual for a home of this size to have a place for holding parties, hosting events, and staging live performances, but you’d be hardpressed to come across another similar space as well realized or as chameleon-like as the one here. 

The room gives few clues to its other capabilities when they’re not in use, feeling causal, comfortable, and domestic. Furniture groupings and large canvases help disguise the stage’s true identity, with the main speakers for performances hidden behind fabric panels in the soffit above the proscenium, and with a dropdown projection screen and monitor speakers tucked into the ceiling of the stage area. 

The client’s desire to have the room provide exceptional sound for parties, fundraisers, and other large events as well as for both movies and live entertainment created a unique challenge for Haas since each use had its own set of not necessarily cross-compatible needs. The music for parties had to be able extend into the bar area, out onto the various terraces, and into other parts of the home as well, while the stereo sound for performances needed to match what you would expect to hear in a high-end nightclub, and the movie system had to supply satisfying surround for groups as large as you’d find in a commercial cinema—all in a wide-open room filled with glass, wood, and other structural and decorative enemies of quality sonic reproduction.  

Haas was especially concerned about architect Alec Tzannes’s design for the ceiling, which used suspended elongated 3/4″ rectangular slats to create a barrel vault that would conceal the multitude of speakers, subwoofers, lighting cans, and ducts. “The client actually flew me over to Sydney to make the case,” says Haas, “because he had consulted with a local acoustic expert who had said there would be no problem. And I looked at it and said, no. This is absolutely wrong.” His solution was to use round dowels instead. “After we did our calculations and I created a physical mockup of the dowel system, we saw that the sound would bend around them in a way that would have a negligible effect.”

The curve of the ceiling was also a problem since it would tend to reflect and focus the sound from the speakers instead of spreading it evenly throughout the room. To help address that, and all the many reflective surfaces, Haas took advantage of the space above the dowels to apply extensive sound absorption.

Not only have the homeowners and their guests been impressed with the result, so have the numerous A-list artists who have sung there—Sting, Michael Bolton, and Australia’s Delta Goodrem among them. “Michael Bolton said it was one of the best-sounding places he’s ever performed in,” says Haas. 

MIXED SIGNALS

Cut to a decade later. The homeowner tells Haas he’s concerned the digital signal processors (DSPs) tasked with handling all the various audio responsibilities are beginning to fail. It’s not that the gear is faulty—it’s just at the end of its lifespan. “It’s not uncommon to see DSPs fail after 10 years,” says Haas. “They’re essentially computers, of course”—which means they’re just as likely to start crapping out as any laptop or desktop PC. And they’re subject to the same rapid technological advancements, with all their inevitable upgrades. Staying a step ahead of the upkeep is just a fact of life with anything this diverse and complex.

Haas saw the task as not a chore but an opportunity to bring all the various types of DSP currently in the house under one brand and system. And while he was at it, why not upgrade the private cinema to Atmos as well?

With its 7.1-channel California Audio Technology speaker array, the cinema had been serving the homeowners well since its inception in the early ‘00s. But, having been impressed by Wisdom Audio’s ceiling speakers, Haas felt that adding eight of them to the room to create an Atmos configuration would significantly enhance the movie-watching experience. And the speakers were compact enough that he could have them installed without having to engage in a massive do-over.

Not that the upgrade wasn’t a challenge. Because they couldn’t dismantle the whole ceiling, Haas wasn’t sure what he, the contractors, and the custom integrators from Sydney-based Datascene would find when they attempted to tap into the preferred speaker locations. So they adopted a surgical approach, working their way carefully around the duct work and other impediments. And because there are bedrooms just above the theater, a tremendous effort had been made during the original construction to ensure none of the sound would bleed through the ceiling. Honoring this, they kept as much of the existing treatments in place as possible as they added the new speakers, also providing sound-isolation caps in each of the speaker locations. 

Premium theaters like this one often rely on a tip-top-of-the-line sound processor from a company like Storm Audio or Trinnov. But Haas went with a Marantz AV8805 instead because it provided the desired sound quality without all the additional bells and whistles of the higher-end models and would more readily work in tandem with the QSC Q-Sys pro-audio DSP he was deploying throughout the other key areas of the home.

It was also time to replace the projector—and rebuild the projection booth, which, located near the cliff face, had been infiltrated by moisture. Haas helped the client pick the new projector, consulting with Barco and coming back with a recommendation for its Wodan model. But this required an acoustical makeover for the booth since the new projector was significantly louder than the previous one and the noise would have been distracting, especially for anyone sitting in the last row, which rests up against the booth wall.

At 38 feet, the room is unusually deep for a private theater. “In a room like that,” says Haas, “you can get so sonically disconnected from the front that by the time you get to the rear seats, it feels like you’re in a different space.” To address this, he used acoustical treatments to disperse the sound so that the experience would be the same no matter where someone is sitting. 

For all the defining trends the Sydney Home represents, maybe the most significant is its extensive blending of consumer and pro gear. As high-end homes incorporate more elaborate entertainment areas like dance floors and live-performance spaces, they need to be able to provide sound on par with what artists expect in professional venues—along with the ability for DJs, sound mixers, and others to be able to jack in their gear.

Also, a multiform multipurpose system as flexible and complex as the one here can quickly exhaust the abilities of the hardware available on the consumer side of things. It often takes robust, function-specific professional gear to rise to these emerging challenges.

Haas, who is just as comfortable working on recording studios, concert halls, and galleries as he is on domestic environments, turned out to be the ideal fit for a project this ambitious. As a member in good standing of that previously mentioned acoustical elite, he was able to bring the necessary combination of expertise and experience to bear. Relying on someone whose knowledge is limited to the residential world to master something like this is a sure-fire recipe for disaster. Since entertainment areas are only going to get bigger, more versatile, and exponentially more complex, better to place them in the hands of people like Haas who not only think, but perform, well outside the home theater box.

Atmos Finally Grows Up

Atmos Finally Grows Up

Atmos Finally Grows Up

The ultimate immersive format no longer relies on filling your room with gimmicky effects just to make its presence known 

by Dennis Burger
April 19, 2022

It never fails. Every time I admit to liking a new Dolby Atmos mix, my fellow home-cinema aficionados refuse to let me live it down. They behave as if I’ve converted to some weird cult, or—more charitably—as if I’ve finally seen the light. You can almost hear them chanting, “One of us! One of us! 

And you could say I brought this on myself, given what a vocal detractor I’ve been of Atmos and other “immersive” audio formats. That I’ve recently had nice things to say about some of these mixes could, I acknowledge, be interpreted as a change of heart. 

It isn’t. I haven’t changed. Nothing about my taste in surround sound mixing has evolved or softened, and if you put any of the abusive, distracting Atmos mixes I’ve griped about over the years in front of me now, I’d gripe just as vociferously. What has changed is that after a decade of trial and error, mixers have finally figured out how to make Atmos work with the films they accompany rather than against them. Of course, I’m not entirely sure you can blame the mixers. After all, those technicians and artists were simply giving early adopters what they demanded. 

We see this sort of thing happen any time a new expansion of sound comes to market. Think back to the awful stereo mix for The Beatles’ Rubber Soul, an album that can only be truly appreciated as a cohesive work in mono. Even a few years later, the stereo mix for Jimi Hendrix’ Are You Experienced was a curiosity at best.

Fast forward to the era of digital surround sound, when DVD arrived on the scene and we were convinced to replace our old surround sound receivers with spiffy new 5.1 models. We all wanted to hear more discrete surround effects and more pronounced deep bass to justify our new purchases. As a result, Hollywood gave us soundtracks like that of The Fifth Element, which made for a great home theater demo but was a major distraction if you wanted to actually enjoy the movie. (Ironically, the 2015 Atmos remix is actually subtler and more immersive—meaning less distracting—than the 5.1 mix included with the original DVD in the late ’90s.) 

It’s no surprise we had to go through the same growing pangs with Atmos. Or perhaps it would be more appropriate to call it an arms race. Those who were first to adopt Atmos at home shelled out a pretty penny to have additional speakers installed in their ceilings, more amps to drive them, and new receivers or preamps to decode and process the soundtracks; and they demanded to be rewarded for their investment with a torrent of sound coming from every which direction. But now that they’ve gotten their cheap fix, the rest of us can finally start to enjoy Atmos mixes that genuinely add something to the experience of watching a film rather than smacking you over the head with a newspaper at every opportunity. 

Take Nightmare Alley. It’s hard to imagine a mix like this one being created—or tolerated—ten years ago at the dawn of Atmos. It’s often—though not always—subtle. There are things going on in the overhead channels almost constantly, but they all work in the service of creating and enhancing the mood of the film and the feel of its environments. It’s the slow roll of thunder overhead and off toward the horizon, as well as the hum of mercury-vapor lamps indoors, that make the film’s locations feel tangible and multi-dimensional. They draw you into the experience rather than pulling you out of it. The soundtrack doesn’t fill your room with sound—it makes your room disappear. You don’t consciously think about where the sound is being placed because it simply feels right.

But I’m not saying Atmos mixes have to be subtle to be effective. The immersive soundtrack for last year’s Dune is incredibly aggressive. It leans on the overhead channels far more than do many of the Atmos mixes from years past that I find overbearing and counterproductive. But re-recording mixers Ron Bartlett and Doug Hemphill knew what they were doing. They didn’t crank up the mix and leave it there. They leaned hardest on the overhead and surround channels at the moments when the film becomes a pure operatic experience of sight and sound, and also when the visuals are simply so compelling no audio gimmick could pull your focus away from the screen. 

There have also been some recent experiments in Atmos that accomplish with sound what The Wizard of Oz did with Technicolor. Last Night in Soho is a perfect example. I can’t imagine that film working nearly as well without the benefit of its inventive 3D sound mix. The very shape of the soundfield is a subtle but unmissable clue about the lead character’s mental state and the delineation between reality and fantasy within the context of the narrative.

Granted, just because we’re getting there doesn’t mean we’re there yet. The recent Apollo 10½: A Space Age Childhood is a sweet and endearing little semi-autobiographical memoir that’s hobbled by an Atmos mix that treats the experience more like a theme-park ride than a work of cinema. Thankfully, such mixes are becoming less common, especially for films of this sort.

All of which is a long and roundabout way of saying that I haven’t come around to Atmos. I haven’t seen any light. I’m not a convert. I’ve long understood the potential of Atmos as a way of further immersing the viewer in the cinematic experience. I’ve simply been disappointed by Hollywood’s insistence upon using it to turn nearly every film into the experiential equivalent of Jaws 3-D. Now that it’s becoming something grownups can actually enjoy, I’m all for it. But make no mistake: I haven’t changed. Atmos has.

Atmos might be a little too unnatural—and gimmicky—to be satisfying as a surround sound experience

by Dennis Burger
January 9, 2019

I have a friend who turns his nose up at surround sound. Press him on the matter and he’ll demur and hedge his argument, but it’s pretty clear he thinks stereo is where it’s at for movies and music alike. And I think he’s absolutely bonkers. 

I mention that not to pick on him but rather to empathize, because I imagine the face I make at him is the same face our own John Sciacca makes at me when I admit that I just don’t like Dolby Atmos—at least not for movies. That might seem strange given that I’m on record as lauding the format—with its overhead speakers and innovative use of audio objects instead of channels—when applied to video games. You haven’t really played Overwatch until you’ve heard Pharah scream, “Justice rains from above!” from above your actual head. 

The weird thing is, I love Atmos with gaming and generally hate it with movies for pretty much exactly the same reasons. And to understand why, you’re going to have to do a little homework.

Take a lawn chair out into your front yard and sit in it with your back to the street. Your neighbors may give you strange looks, but this is for science. Just run with it.  Now pull out a book and start reading it. At some point, a car might drive by behind you. If the book is decent enough, chances are you won’t even notice, unless you live on a street so remote that passing traffic is an oddity. 

Keep on reading until a plane or helicopter passes overhead. Your concentration immediately broke, didn’t it? OK, maybe not if you live near an airport or airbase, and you’re used to planes flying overhead. But for most of us, if something flies overhead, we’re gonna drop the book and look upward. 

Atmos is a lot like that for me. It triggers something in my primate brain—a fight-or-flight mechanism, if you will. I’m reminded of vervet monkeys, who have different words in their rather complex vocabulary for “python” and “eagle.” If a monkey shouts “python,” nearby members of its tribe scan their surroundings. If the cry is “eagle,” on the other hand, they drop what they’re doing and run for the nearest hidey hole. 

And Atmos generally does that to me. There’s just no denying that sound coming from overhead is hardwired into our brains as something we have to focus on. In a video game, that can be critically important since these virtual worlds often contain threats coming from every direction. Hearing that a baddy is attacking you from overhead can be the difference between virtual life and death.

But unlike video games, movies aren’t sandboxes. Our focus is on a rectangle of space right in front of us; someone else gets to decide where our eyes turn. It’s an inherently horizontal experience, and while sounds coming from the sides and behind don’t violate that experience, sounds coming from overhead do. As with our daily lives, anything that happens outside of that horizontal plane is somehow distinct, different, and disconnected.

That can actually be kinda cool with movies like Ready Player One or others that live or die purely on audiovisual spectacle. Heck, it’s even great with movies like The Last Jedi, where the overhead sound effects generally work to add ambiance and a sense of space, not vertical sensationalism. But such mixes are few and far between. For the most part, Atmos serves only to distract me from the narrative experience. And just to be clear, I’m not saying John or anyone else is wrong for liking that effect. I’m merely rebelling against the increasingly pervasive notion that if you don’t have an Atmos-capable sound system, you’re somehow doing home cinema wrong.

Try to seek out an Atmos demo before you decide if this “immersive” audio technology is right for you. And if it’s not—if tried-and-true surround sound does the trick—don’t feel like you’re selling your movie-watching experience short. I mean, as long as you’re not just watching movies in stereo . . .
