Subscribe to our newsletter For many of us, being able to watch movies and TV shows in the best possible quality at home is something we aim to achieve. Realistically, that will mean pairing one of the best TVs with one of the best soundbars . For the
fortunate few, however, the possibility of having a dedicated home theater space, complete with rows of chairs, soundproofing and a cinema-like projection system is one thats very real indeed (the rest of us are still
able to drool over enviable custom install theaters, of course).

And nobody does custom home theater installations quite like David Moseley
and his company, Wavetrain Cinemas. Based in Australia, Wavetrain Cinemas has the distinct recognition of being awarded Best Global Home Cinema on two separate occasions by CEDIA, the international trade association representing the professional home automation/smart home technology industry. While its easy to just look at images of Wavetrain installations and think Id love to have something similar one day, the more interesting question is how each space is actually designed to perform at such a high level. I was recently able to put some questions to David, and according to him, the answer starts with a framework rather than a product list.

Wavetrain is guided by CEDIAs RP22 recommended practice for immersive audio design, which sets out key parameters including sound pressure level (SPL) capability, speaker coverage, seating geometry and overall system design. Within this structure, David has formed his own priorities that he believes make for the best home cinema install: seat-to-seat consistency, low distortion at reference levels and controlled decay times. No more sweet spot That first point is especially important. For Moseley, consistency means
every listener should experience the same tonal balance, imaging and impact regardless of where they sit. I know for me, whenever I visit my local
cinema, I do try to make sure Im able to grab the centermost seat, as I feel it will give me the most immersive experience, particularly where sound is concerned, as all the speakers will be firing into the rooms central
position. For each seat in a smaller cinema to receive the same level of performance is no easy task.

For Wavetrain, it is that goal which drives choices around speaker selection, placement and room geometry. The second priority is effortless dynamics the ability to reach reference-level SPL without distortion or strain. The third is time-domain performance, particularly decay times, so that the room preserves detail, clarity and spatial cues instead of delivering a sound
thats entirely muddied.

David admits its not always as easy as just running some software to give accurate calculations. He says that every cinema design involves compromise, and that inexperienced designers often get stuck trying to make a theory-driven layout work even when it doesnt sound right in the room. David takes a different approach to compromises, if theyre to be made at all. We never allow a design decision that results in a compromise the client can actually hear, he says.

His installations are never rushed either, as you might expect, and instead
he and his team will spend a lot of time upfront with clients often three or four hours to explain the technology options, the expectations and the consequences of different choices before a single decision is locked in. (Image credit: Wavetrain Cinemas / Kaleidescape) Its not the size that
counts, its how you use it For David, the majority of a cinema installations design process relates to the room itself and how its acoustic properties
will affect the resulting performance. Indeed, the companys primary metric is reverberation time across the full audible range.

If youre reading that line and not really understanding what David means, he explains it quite clearly when he says, You can hear this in everyday life, your voice changes as you move from one room to another. What to read next I heard two 'invisible' speakers that truly give you a 'wall of sound' I tested LGs most hardcore Dolby Atmos FlexConnect setup, and it's superb The best Dolby Atmos soundbars: home theater upgrades for all budgets

A cinema is no different. Every sound is shaped by the space it exists in.

And finding the perfect sound for any room isnt dictated solely by numbers, This is where acoustics moves beyond pure science and becomes an art form, says David.

"There are simply too many variables for it to be automated effectively. Measurement data must be interpreted by someone who understands both the physics and how we perceive sound.

Good acoustics may be invisible, but they are what make the difference
between a system that merely measures well and one that truly feels right to listen to. As he puts it, "nothing can replace good room design." Effective home upgrades If youre in the process of completing your own custom install, or you have plans for the future, and if youre working with a limited budget, that philosophy has practical implications too. Moseley argues that the highest-impact improvements are often the simplest ones, move seating away from walls to improve bass consistency, he says.

Other simple adjustments can include adding basic acoustic treatment to improve dialogue clarity, while also eliminating rattles and unwanted noises, and sitting closer to the screen and speakers so the system doesnt have to work as hard, which can also have positive effects. He also notes that there is always a performance sweet spot, beyond which gains become disproportionately expensive. In other words, the smartest upgrade is not always the most expensive one. (Image credit: Wavetrain Cinemas / Kaleidescape) For the rest of us with more conventional living room setups, there are still things you can do to maximize performance. While a TV and soundbar combo wont match the isolation of a dedicated home cinema, the underlying principles dont change. As David explains, CEDIA RP22 is a recommended practice for immersive audio, not just dedicated cinemas, so the same standards apply to any multi-channel system in any space.

There are extra challenges of course, in layout, materials and sound isolation, but David says with the right approach to acoustic treatment, system design, and integration, a living space can still deliver exceptional performance.

In many cases, acoustics can be seamlessly integrated into the design through elements like curtains, rugs, joinery and furniture, rather than being visually obvious. Elementi, my dear movie lover That is also where Elementi, Wavetrains speaker brand, comes into the picture. Moseley positions it as a bridge between premium hi-fi and commercial cinema systems, but with a more refined approach. He says that most high-end hi-fi speakers are designed for nearfield listening, typically within one to two and a half meters, and many will struggle to maintain performance beyond three meters.

Conversely, he adds that commercial cinema speakers are designed to meet specific SPL requirements set by organizations such as Dolby. Elementi speakers have been designed to bridge this gap.

That means theyre built to be able to sustain high output continuously, while keeping distortion to an absolute minimum, and doing so through a fully
active design with dedicated amplification for each component.

Going down an active route has multiple benefits, and David says that one of the biggest is that it reduces impedance-related losses and eliminates many
of the issues associated with long speaker cable runs, which in home cinemas can often exceed 1030 meters. (Image credit: Wavetrain Cinemas /
Kaleidescape) Location, location, location With regard to speakers, I asked David which had greater impact, the speaker itself or how its integrated into the room. He said, both matter, but integration has the greater impact.

A speaker must be fundamentally suited to its intended application, but even the best speaker will underperform if its poorly positioned or placed in an inadequately designed room.

If youve ever listened to a traditional 2.0 hi-fi speaker setup and moved yourself around the room, you would have noticed that the overall sound can change. This is due to the way soundwaves are delivered into the room, and
how theyre picked up by your ears. Its a similar story for home cinema
setups, Speaker placement directly affects the soundstage, says David.

Small errors can have significant consequences. And while some of this may sound obvious, in practice we still see it done incorrectly far too often. (Image credit: Wavetrain Cinemas / Kaleidescape) He adds that when hes inspecting a clients current space, we regularly come across ceiling speakers aimed straight at the floor rather than the listener, front wide speakers firing across the room instead of into the seating area, or surround speakers positioned in ways that completely confuse spatial perception.

And dont think that subwoofers can get away with being placed anywhere in the room, as David argues that low-frequency performance is also heavily influenced by placement.

The goal of a well-engineered system is to allow the listener to experience the full capability of the speakers theyve invested in. That comes down to three things, in order: room design, speaker positioning and finally calibration. Source it to me Moseley is equally focused on the quality of the source material feeding the system. He places strong emphasis on low-jitter digital playback, arguing that jitter introduced in the digital domain ultimately becomes noise after conversion. In his view, those small imperfections add up, especially in systems built to the highest standard. That is one reason Kaleidescape has become so common in Wavetrain projects
it offers exceptional build quality, low jitter and a large 4K library with lower compression than UHD discs in many cases.

Ive personally had some experience with Kaleidescape, having reviewed the Strato E 4K player last year. While I was aware of the potential visual and audible benefits it would bring compared not only to streaming services, but 4K Blu-ray discs too, I wasnt sure just how much of a difference there would be. (Image credit: Wavetrain Cinemas / Kaleidescape) Sound was perhaps the biggest differentiator, and I felt I was able to unlock even more potential, even from my humble Sonos home theater setup. I can only imagine the level of performance achievable in a dedicated space such as a Wavetrain cinema.

For us, performance begins with a clean, stable signal, says David.

Kaleidescapes exceptional build quality is a key reason it measures as the lowest-jitter source currently available. Combined with the largest 4K media library often with lower compression than UHD discs it becomes an ideal media source. Its no surprise that nearly every cinema weve delivered over
the past five years has included Kaleidescape.
