01 / Acoustics · RT60: 0.32s · 7.2.4 Dolby Atmos
01 EDC · Elevated Digital Cinema Xperience
Most disappointing home theaters in Hyderabad have good equipment in an untreated room. Vitrified tile, Italian marble, glass and RCC walls reflect sound almost perfectly, so dialogue smears, bass booms at one seat and vanishes at the next, and overhead effects lose their position.
EDC is our design method for fixing that at the source. We start with the room's dimensions and construction stage, choose a speaker layout that fits it, plan acoustic treatment around your interior design, and finish with measured calibration. The result is a cinema that sounds the same at the back row as at the director's chair.
Every project is drawn first: speaker angles to Dolby's placement guidelines, seating distance for your screen size, riser height for clear sightlines, and conduit routes your builder can follow before plastering.
02 Room topology matrix
Three formats cover almost every Hyderabad home. Each layout below is a real planning starting point, with indicative turnkey budgets.
12×15 ft · 5.1.2 · Indicative ₹2.2 – 4.5 Lakhs
Ideal for apartments in Gachibowli, Kondapur and the Financial District where the living room doubles as the cinema. Speakers go in-wall or in-ceiling so the room still looks like a living room.
| Room volume | ≈ 1,800 cu ft at a 10 ft slab |
|---|---|
| Speakers | LCR + 2 surrounds + 2 in-ceiling Atmos + 1 subwoofer |
| Processing | 7-channel Dolby Atmos AV receiver (Denon / Marantz) |
| Display | 75–85" 4K TV or 100" ALR screen with laser UST projector |
| Seating | Single row, 3–4 seats; sofa can stay |
| Acoustics | Rug, curtains and 4–6 absorptive panels at first reflections |
15×20 ft · 7.2.4 · Indicative ₹6.5 – 14 Lakhs
The most-requested format for villa basements in Kokapet and Tellapur. Two subwoofers smooth bass across both rows, and four overhead channels place rain and flyovers precisely above the seats.
| Room volume | ≈ 3,000 cu ft at a 10 ft slab |
|---|---|
| Speakers | LCR behind screen + 4 surrounds + 4 Atmos + 2 subwoofers |
| Processing | 11-channel processing with room correction |
| Display | 120–135" acoustically transparent screen, native 4K projector |
| Seating | Two rows of motorized recliners, second row on a 12–18" riser |
| Acoustics | Target RT60 ≈ 0.3 s, corner bass traps, rear-wall diffusion |
18×28 ft · 9.2.6 · Indicative ₹15 – 30 Lakhs+
Built for estates in Jubilee Hills and Banjara Hills where the cinema is a destination. Front wides close the gap between screen and surrounds so pans feel continuous for every seat, not just the centre.
| Room volume | ≈ 5,000+ cu ft, often double-height |
|---|---|
| Speakers | LCR + front wides + 4 surrounds + 6 Atmos + 2 or more subwoofers |
| Processing | Separate processor + multichannel power amplification |
| Display | 150"+ scope or 16:9 screen, JVC D-ILA or 4K laser projection |
| Seating | Three tiers of custom motorized recliners |
| Acoustics | Room-in-room isolation, acoustic doors, quiet HVAC (NC 25) |
03 Theater speakers
Dialogue lives in the centre channel, so the left, centre and right speakers must be timbre-matched — ideally identical — and placed at ear height or angled toward the seats. In dedicated rooms we mount them behind an acoustically transparent screen so the voice appears to come from the actor's mouth.
Surrounds sit slightly above ear level at roughly 90–110° for 5.1 layouts, with rear surrounds at 135–150° for 7.x systems. Front wides, used in 9.x rooms, bridge the gap between screen and side walls so pans feel seamless.
We specify from Klipsch, Episode and QSC depending on room size, target loudness and whether the speakers should disappear into walls or stand as furniture.
Speaker planning rules we follow
04 Acoustics & calibration
Treatment is planned with your interior designer so it reads as fabric wall panelling, timber slats or a feature wall — not a recording studio. Below is what goes into a typical AV Box private cinema.
RT60 is how long sound takes to decay by 60 dB. An untreated tiled room in Hyderabad often measures 0.8–1.2 seconds, which blurs dialogue and effects. For a private cinema we usually target about 0.25–0.4 seconds across the midrange, evenly — the goal is a controlled room, not a dead one.
Fabric-wrapped Rockwool or polyester panels go at first-reflection points on side walls and the ceiling. Thick corner bass traps tame the low-frequency build-up that hard RCC boxes produce. The rear wall gets diffusion so the room keeps a sense of space instead of sounding muffled.
Isolation keeps the cinema from waking the house and keeps traffic and generator noise out. Depending on budget we use decoupled stud walls with double drywall and damping compound, isolation hangers for the ceiling, a solid-core acoustic door with seals, and low-velocity AC diffusers so air noise stays below the soundtrack's quietest passages.
05 Projectors & screens
Screen size follows seating distance, not wall size. In a dedicated room we aim for an immersive viewing angle of roughly 40–50° from the main seat, which usually means a 120–150 inch screen in a 15–28 ft room. The projector is then chosen for that screen's size, gain and the room's light control.
For dark, dedicated cinemas, native 4K JVC D-ILA projectors deliver deep contrast. For media rooms and living spaces with daylight, 4K laser projectors from BenQ and Optoma pair well with ambient-light-rejecting screens, including ultra-short-throw models that sit just below the screen.
| Room type | Projection | Screen |
|---|---|---|
| Dedicated, light-controlled | Native 4K / laser, long throw | Acoustically transparent, gain ≈ 1.0 |
| Media room, some daylight | 4K laser, high brightness | ALR, fixed frame |
| Living room | 4K laser UST or large-format TV | UST-specific ALR or none |
06 Theater seating
Seating is where comfort meets acoustics. We plan seat width, recline clearance from the rear wall, aisle widths and riser height together, so the second row sees over the first and every head sits within the speakers' sweet spot. A 12–18 inch riser is typical for a two-row private cinema.
Motorized recliners with adjustable headrests, USB charging and cup holders are standard; tactile transducers can be added for low-frequency effects you feel through the seat. Upholstery options run from performance fabric to leather, chosen to match the room's acoustic panelling.
07 Beyond the cinema room
A 5.1.2 Dolby Atmos system that suits a formal living room: slim front speakers or in-wall LCR beside the TV, a subwoofer tucked into joinery, and Atmos speakers in the false ceiling. Your sofa stays where your interior designer wants it.
5.1.2 · Concealed
In-ceiling speakers with back cans, mounted in the gypsum false ceiling below the RCC slab. Back cans prevent sound leaking to the floor above and keep bass consistent. Paintable, edge-to-edge grilles disappear into the ceiling.
Back cans · Paintable
Independent music zones for the kitchen, bedrooms, deck and pool, streamed from your phone with HEOS-enabled Denon and Marantz electronics or a centralized amplifier in the rack. Zones can join an automation scene, so "Evening Lounge" starts the music too.

FAQ · Straight answers
As an indicative turnkey guide: a 5.1 or 5.1.2 living-room system is ₹2.2–4.5 lakhs, a dedicated 7.1.4 or 7.2.4 private cinema with acoustics is ₹6.5–14 lakhs, and a 9.2.6 reference screening room with recliners and isolation starts around ₹15 lakhs and can exceed ₹30 lakhs. The final quote follows a site or blueprint review.
Around 15×20 ft with a clear ceiling height of at least 9.5–10 ft works well for two rows of seating, four overhead speakers and a 120–135 inch screen. Smaller rooms can run 5.1.2 or 7.1.4 very effectively with careful placement.
Ideally before plastering and false-ceiling work. That is when speaker back boxes, conduits, projector power and data, subwoofer locations and acoustic framing can be planned at almost no extra cost. Retrofits are possible, but planning early avoids chiselling finished walls.
Yes. Hard, parallel surfaces cause echo, flutter and uneven bass. We measure and treat the room with absorption at first-reflection points, bass traps in corners, diffusion on the rear wall and a rug or carpet, typically targeting a reverberation time (RT60) of around 0.25–0.4 seconds.
