Designed by AV Consultants – Detailed Installation & Performance Analysis

Experience Cinema-Grade Performance at Home Without the Clutter of Large Speakers

Hello everyone, I’m Deepak Saxena from AV Consultants, and today I’m going to walk you through one of our most popular premium home theatre configurations designed for homeowners who want reference cinema sound with a clean architectural design.

At AV Consultants, based in Mohali and serving customers across Punjab, Chandigarh, Haryana, Himachal Pradesh, and North India, we specialize in luxury home theatre design, Dolby Atmos installations, projector systems, and acoustic room engineering.

Many modern homeowners want the immersive experience of a commercial cinema but do not want large floor-standing speakers dominating the room. To solve this challenge, we design architectural systems using high-performance in-wall and in-ceiling speakers.

KEF Ci4100QL THX 7.2.2 Home Theatre System

Architectural Dolby Atmos Cinema with KEF, JL Audio & Arcam

At AV Consultants, we specialize in designing and installing premium home theatre systems that combine advanced acoustic engineering, high-end electronics, and professional calibration.In this article, we explore a reference-quality 7.2.2 Dolby Atmos home theatre system built using:

• KEF Ci4100QL-THX architectural speakers

• JL Audio Dominion d110 dual subwoofers

• Arcam AVR5 AV receiver

This configuration offers exceptional cinematic performance while maintaining a sleek architectural design.

What Is a 7.2.2 Dolby Atmos Home Theatre System?

Before diving into the equipment, it is important to understand the 7.2.2 home theatre layout. The numbers represent the number of speakers in the system:

7 – Surround Speakers

• Front Left

• Front Center

• Front Right

• Side Surround Left

• Side Surround Right

• Rear Surround Left

• Rear Surround Right

2 – Subwoofers

These handle deep bass frequencies.

2 – Height Speakers

Dolby Atmos ceiling speakers add vertical sound effects.

This configuration creates a three-dimensional audio environment, allowing sound to move around and above the listener.

Compared to traditional 5.1 systems, 7.2.2 systems deliver a much more immersive cinematic experience.

KEF Ci4100QL THX In-Wall Speakers

The primary speakers in this system are the KEF Ci4100QL-THX, part of KEF’s professional architectural speaker range.

These speakers are THX-certified, meaning they meet strict performance standards for home theatre applications.

Uni-Q Driver Technology

One of KEF’s most important innovations is the Uni-Q driver array.

Unlike conventional speakers that separate tweeter and midrange drivers, KEF places the tweeter in the center of the midrange cone.

This creates a single acoustic point source, which offers several advantages:

• wider sound dispersion

• better imaging

• consistent sound across multiple seats

• improved dialogue clarity

This technology is especially beneficial for home theatres with multiple seating positions.

Performance and Specifications

The KEF Ci4100QL-THX is designed to deliver powerful and accurate sound despite its slim architectural design.

Typical specifications include:

Frequency Response

55Hz – 28kHz

Sensitivity

89 dB

Impedance

4 ohms

Driver Configuration

• Uni-Q midrange/tweeter

• Three 4-inch bass drivers

Because of its design, the speaker can be used vertically or horizontally, making it ideal for LCR installations behind screens or TVs.

Front Stage Configuration

The front stage is the most critical part of any home theatre system.

In this setup, three KEF Ci4100QL-THX speakers are used for:

• Front Left

• Center Channel

• Front Right

Using identical speakers for all three front channels ensures perfect tonal matching.

This allows sound to move smoothly across the screen during scenes such as:

• cars driving across the screen

• aircraft flyovers

• moving dialogue

The result is seamless cinematic realism.

Surround Speaker Placement

Surround speakers create the immersive sound field around the audience.

Side Surround Speakers

Two KEF speakers are installed on the side walls slightly behind the listening position.

These speakers reproduce:

• environmental sounds

• background ambience

• directional effects

Examples include:

• wind

• crowd noise

• footsteps moving through a scene

---

Rear Surround Speakers

Two additional KEF speakers are installed on the back wall of the theatre.

These extend the sound field behind the audience.

Rear surrounds enhance scenes such as:

• explosions behind the viewer

• vehicles approaching from the rear

• battlefield environments

Together with the side surrounds, they create a complete 360-degree surround sound experience.

---

Dolby Atmos Height Speakers

Dolby Atmos technology introduced object-based audio, allowing sound designers to place audio anywhere in three-dimensional space.

To achieve this effect, the system includes two ceiling-mounted Atmos speakers.

These speakers reproduce overhead sound effects such as:

• helicopters flying overhead

• thunder and rain

• aircraft flyovers

• environmental ambience

Even with only two height channels, Dolby Atmos significantly improves the sense of immersion compared to traditional surround sound systems.

---

Dual Subwoofer Configuration

Low-frequency performance is handled by two JL Audio Dominion d110 subwoofers.

JL Audio is widely respected for producing some of the best subwoofers in the world, used in both professional studios and high-end home theatres.

Dominion d110 Features

Driver

10-inch long-throw woofer

Amplifier

750W Class-D amplifier

Frequency Response

Down to approximately 27Hz

The Dominion series combines compact size with powerful bass performance.

Why Two Subwoofers Are Better Than One

Many people assume one subwoofer is enough, but dual subwoofers provide significant advantages.

Benefits include:

• smoother bass EVEN response throughout the room

• fewer bass nulls and peaks

• improved impact during action scenes

• more balanced sound for multiple seats

In large or medium-sized home theatres, dual subwoofers dramatically improve the listening experience.

Arcam AVR5 AV Receiver

To power the system, we use the Arcam AVR5, a premium AV receiver known for its excellent sound quality.

Unlike many mass-market receivers, Arcam focuses on high-quality amplification and advanced room correction.

Key Features

• Dolby Atmos and DTS decoding

• high-current amplification

• HDMI connectivity for modern sources

• network streaming support

The AVR5 is an ideal match for high-end architectural speakers like KEF.

Dirac Live Room Calibration

One of the standout features of the Arcam AVR5 is Dirac Live room correction.

Room acoustics have a huge impact on how a home theatre sounds.

Even expensive speakers can sound poor in an untreated room.

Dirac Live analyzes the room using a measurement microphone and applies advanced digital filters to correct:

• frequency response

• timing alignment

• bass performance

The result is:

• clearer dialogue

• tighter bass

• better soundstage imaging

Professional calibration can make a dramatic improvement in system performance.

Advantages of Architectural Home Theatre Systems

Architectural speakers have become increasingly popular for luxury home theatres, offering a perfect combination of high performance and elegant design. Unlike traditional floor-standing speakers, these systems are integrated directly into walls or ceilings, creating a minimalist and clutter-free interior. With all wiring hidden inside the walls, rooms remain clean and organized without visible cables or bulky cabinets, making architectural speakers ideal for bedrooms, living rooms, and dedicated home theatres. Modern solutions from KEF provide sound quality comparable to traditional speakers, delivering clear dialogue, detailed music reproduction, and immersive Dolby Atmos surround sound. Proper home theatre installation is essential to maximize performance, including speaker placement, acoustic treatment, cable management, and professional calibration. At AV Consultants, every system is designed to achieve optimum sound and reliability, and we invite you to experience a live demo featuring KEF architectural speakers, JL Audio subwoofers, and Dirac-calibrated immersive audio, so you can hear the true difference between a standard audio system and a premium home theatre.
