Roland Koller’s Last Home Cinema – HeimkinoWelt Completes an Extraordinary Reference Project

Roland Koller’s final Home Cinema has been completed in its definitive technical configuration. Widely recognised far beyond Austria as an authority on professional Home Cinema, he built his reputation on projects in which picture, sound, room acoustics and control were planned as interdependent parts of one system. Following his death in 2025, the Vienna specialist retailer HeimkinoWelt assumed responsibility for this last reference installation at his express request, updated its technology and documented the complete configuration. Its components are now being offered for the first time, including a Christie professional 4K projector, a complete JBL Synthesis loudspeaker system, a Trinnov Altitude16 AV processor, Crown digital power amplifiers and CINEAK cinema seating.

A Cinema Defined by Its Author

The significance of this installation does not begin with its equipment list. It begins with Roland Koller and his understanding of what a professionally designed Home Cinema should be.

His standing extended well beyond Austria. Within the international Home Cinema community, Roland Koller was regarded as an acknowledged expert in sophisticated, uncompromising cinema installations. He did not work from a standard formula, nor did he treat expensive components as a guarantee of quality. Every project was developed as a coherent whole in which the individual products could realise their potential only through meticulous planning, acoustic optimisation and exact calibration.

That principle governed the design of this cinema. Loudspeakers, subwoofers, signal processing, amplification, projection and room acoustics were not considered in isolation. Each decision served the complete installation.

As Roland Koller’s last project, the cinema consequently carries a significance beyond its already remarkable technical scale. It records the working methods of a planner who never separated the image from the sound, the room from the equipment or the technology from its operation.

A Final Request and an Exceptional Responsibility

Before his death in 2025, Roland Koller expressly asked HeimkinoWelt to take care of this reference Home Cinema. The request itself speaks of the trust he placed in Thomas Chuchlik and Ing. Roland Scholz.

Few could be better qualified to continue this professional legacy. HeimkinoWelt shares the central conviction behind Koller’s work: a first-class Home Cinema must be planned as a connected system from the outset. Individual products may offer extraordinary capabilities, but their selection, placement, integration and calibration ultimately determine the result.

Taking over the cinema therefore involved considerably more than administering a large installation. The Vienna specialist retailer had to continue an exceptional project responsibly while respecting the ideas on which it had been built.

HeimkinoWelt brought the system up to its final technical standard and documented the components in full. This preserves a clear account of the role each product performed and the way in which the individual elements were combined.

Such documentation is particularly important in an installation of this scale. Neither a professional projector nor a powerful loudspeaker system operates independently of its surroundings. Room dimensions, positioning, acoustic conditions and signal processing remain fundamental. Anyone acquiring one or more of the components can therefore also request assistance with planning, calibration, transport and installation.

Updating the Technology Without Abandoning the Concept

The technical revision carried out by HeimkinoWelt did not turn the cinema into a different project. It brought the installation up to date while retaining its original system architecture.

At its centre is the Trinnov Altitude16 AV processor with HDMI 2.1. It acts as the central point through which the picture and audio signals pass before the individual channels are processed and routed to the amplifiers. Its responsibilities also extend to adapting the system to the acoustic conditions of the room.

Power is supplied by two Crown digital amplifiers: a Crown DCi 8|300 and a Crown DCi 4|600N. Designed for professional installations, these amplifiers provide the output required by the extensive JBL Synthesis loudspeaker configuration.

This combination reflects the logic of the entire cinema. The processor, amplification and loudspeakers were chosen for distinct roles within a coordinated installation, rather than because of the prominence of their respective brand names.

JBL Synthesis Across the Entire Sound Field

The three front channels are handled by JBL SK2-3300 loudspeakers. They reproduce the channels at the centre of much of the film’s acoustic action and establish the sonic foundation across the front of the room.

Six JBL Synthesis SCL-4 In-wall loudspeakers serve the side and rear channels. Their wall-integrated installation supports a cleanly arranged cinema interior without reducing the number of loudspeakers required to create an enveloping and continuous sound field.

Low-frequency reproduction is distributed across two JBL S1S EX models and one JBL 5628 professional subwoofer. Using several subwoofers creates the basis for integrating deep bass into the room in a controlled manner.

The result nevertheless depends on far more than the presence of three capable subwoofers. Their positions, the acoustic behaviour of the room and the calibration of the entire system determine how evenly the lowest frequencies reach the listening positions. These were precisely the disciplines Roland Koller regarded as integral parts of Home Cinema planning.

Professional 4K Projection from Christie

The scale of the visual installation becomes evident in the choice of projector. The Christie Mirage 4K32 is not a conventional domestic Home Cinema model, but a professional 4K projection system.

Equipment in this class requires a suitable installation environment, sufficient space and accurate alignment with both the screen and the wider projection conditions. It cannot simply be positioned in an existing room and expected to perform as intended.

In this project, image size and visual impact were not compromises imposed by a pre-existing living space. The room was itself part of the design and was planned specifically around the reproduction system. The Christie projector therefore represents not merely a premium source of images, but one part of an architectural and technical concept.

CINEAK Largo – Seating as Part of the System

CINEAK Largo cinema seats also form part of the final configuration. Although seating might initially appear to concern comfort alone, it has a direct technical relevance in a reference cinema.

Viewing distance and eye level affect the perceived size and impact of the projected picture. Seat positions are equally important to the way the audience experiences the loudspeaker system and its calibrated sound field.

The CINEAK seating was consequently not added as decoration after the system had been planned. Its arrangement established the principal viewing and listening positions around which the cinema was aligned and calibrated.

The Components of the Final Configuration

A Specialist Sale, Not a Conventional Clearance

HeimkinoWelt is offering the components only after personal consultation. That restriction is entirely appropriate to products taken from a project of this nature.

Dimensions, installation requirements, existing electronics and the acoustic conditions of the intended room must be considered before any individual component can be recommended for a new Home Cinema. A product that performed a particular task within Roland Koller’s system cannot automatically be assumed to fulfil the same role in a different environment.

HeimkinoWelt therefore provides more than information about the condition, scope of delivery and technical details of the equipment. Personal advice, professional planning, precise calibration and assistance with transport and installation are also available on request.

This approach retains an essential part of the original thinking behind the cinema: professional Home Cinema technology should be deployed within a carefully designed system, not judged or installed in isolation.

A Legacy Capable of Shaping New Cinemas

Selling the components will bring the original installation to an end, but it need not conclude their story. The projector, loudspeakers, subwoofers, AV processor, power amplifiers and cinema seats may become defining elements of newly designed Home Cinemas.

Their particular relevance is not based solely on their status as professional High-end products. They were selected for an exceptional reference cinema, installed as parts of one coordinated system and subsequently documented by HeimkinoWelt.

Every item is available only in the quantity used in the original installation. Some of the products may be acquired together, while others may ultimately be incorporated into entirely new systems. HeimkinoWelt will provide details of availability, condition, supplied accessories and possible combinations during a personal consultation.

Getting to the Point

Roland Koller was not merely an influential figure within Austria’s Home Cinema community. He was recognised far beyond the country’s borders as an expert who planned every project with exceptional discipline and always understood a cinema as a complete system.

His personal request that HeimkinoWelt assume responsibility for his final reference installation should therefore not be underestimated. Thomas Chuchlik and Ing. Roland Scholz are particularly worthy custodians of that legacy because their work follows the same fundamental principle: professional Home Cinema is created through experience, careful planning and exact coordination between room, picture and sound – not through a collection of spectacular components.

HeimkinoWelt has updated the installation, documented its architecture and supports the components’ future use through personal consultation. This prevents their sale from becoming an indiscriminate clearance of used equipment. Instead, it represents the responsible transfer of an internationally recognised piece of Austrian Home Cinema history.
