Speaker System
The Speaker System
Bowers & Wilkins CT 7.3 LCR
Bowers & Wilkins CT 7.3 LCR speakers handle the left, center, and right channels with Nautilus tube-loaded tweeters etching dialogue sibilants surgically and 7-inch Continuum cone midbass drivers delivering visceral impacts through the AT screen. Three CT 7.3 units ensure perfect timbre match, anchoring Bollywood monologues across the recliner rake; rigid infinite baffle wall-mounting eliminates rear-wave interference, maintaining front-stage coherence in the 330 sq. ft. theatre.
Bowers & Wilkins CT 7.4 LCRS
Bowers & Wilkins CT 7.4 LCRS speakers create surround and surround-back envelopment with dual 6-inch Aramid Fibre woofers radiating controlled dispersion bullet whiz-bys track flawlessly from front wall to rear recliners, matching CT 7.3 tonality and preserving soundtrack continuity. The vented-box design pressurizes room air, delivering cinema reference dynamics without compression.
Bowers & Wilkins CCM 7.5 S2
Bowers & Wilkins CCM 7.5 S2 in-ceiling speakers deliver the Dolby Atmos overhead dimension with a 7-inch midbass and decoupled tweeter, raining rainstorms and helicopters above the six recliners. The pivot mechanism optimizes height angle, matching the wall CT tonality; flush-mount grilles preserve room aesthetics while infinite baffle loading extends bass response.
Bowers & Wilkins CT SW 12 Passive Subwoofers
Bowers & Wilkins CT SW 12 passive subwoofers anchor the low end with twelve-inch long-throw drivers pressurizing 330 sq. ft. uniformly strategic corner placement eliminates room modes, ensuring consistent LFE across all recliners. Their passive design allowed the SA 1000 amplifiers to provide dedicated, DSP-controlled power to each pair.
Bowers & Wilkins SA 1000 Subwoofer Amplifiers
Two SA 1000 subwoofer amplifiers deliver 1000W bridged power per pair with DSP crossover, matching the B&W mains seamlessly. Their built-in DSP capability allowed precise integration between the subwoofers and the CT main channels, ensuring the bass transition was smooth and transparent at all listening levels.
Electronics & Processing
Electronics & Processing — Yamaha AVENTAGE CX-A5200 + MX-A5200
Yamaha AVENTAGE CX-A5200
The Yamaha AVENTAGE CX-A5200 11.2-channel preamp/processor decodes Dolby Atmos and DTS:X with ESS Sabre Premier DACs. YPAO R.S.C. calibration executes 8-mic positions taming Sangli room modes, while SURROUND:AI analyses scenes in real time, optimizing the 7.4.4 channel balance dynamically. It served as the processing intelligence of the entire theatre system.
Yamaha AVENTAGE MX-A5200
The MX-A5200 11-channel power amplifier delivers 150W per channel across all 11 channels, driving the Bowers & Wilkins CT array cleanly with balanced XLR connections eliminating noise. Its 11-channel capacity meant the entire theatre could be powered from a single amplifier platform, keeping the installation streamlined and the signal path consistent.
Projection System
Projection System
Optoma UHD300X Native 4K DLP Laser Projector
The Optoma UHD300X native 4K DLP laser projector punches 4000 lumens through controlled lighting PureMotion eliminates judder during fast action, vertical lens shift optimizes the 150-inch throw without keystone. The 20,000-hour laser source survives Maharashtra family marathons, maintaining colour accuracy throughout its lifetime without the lamp degradation that affects conventional projectors.
Elite Screens 150″ 16:9 Acoustically Transparent Fixed Screen
The Elite Screens 150-inch 16:9 acoustically transparent fixed-frame screen allows the CT 7.3 LCR speakers to be positioned behind the perforations without phase disruption. The 1.1 gain preserves brightness uniformity across all six recliners, while micro-perforation maintains high-frequency extension, matching the B&W tweeters flawlessly.
Acoustics, Soundproofing & Seating
Acoustics & Soundproofing — Complete Cinema Optimization
Double-layer drywall with Green Glue isolation contains 120dB peaks preventing mansion disturbance; GIK Tri-Trap corners eliminate subwoofer modes below 30Hz; 2-inch absorption panels scatter first reflections preserving imaging; ceiling clouds control Atmos CCM 7.5 S2 flutter multi-mic calibration achieved less than 2dB variance, creating uniform 7.4.4 envelopment rivalling commercial cinemas.
Seating Integration — 6 Little Nap Recliners
Custom 6-seater little nap recliners were positioned per THX geometry, optimizing Atmos immersion motorized positioning aligns ear height with the CT 7.3 tweeters, and leather upholstery survives Sangli’s dry air. The seating layout was as carefully planned as the speaker system, because correct ear height and distance from each speaker directly affects the precision of the Atmos imaging.
