Real-world facts

The cutaway perspective reveals the structural, mechanical and acoustic integration of an advanced private cinema built around an ultra-short-throw projection system. At the front wall, a 130-inch fixed frame screen provides a vast visual canvas spanning roughly 2.88 metres in width and 1.62 metres in height. Pairing a display of this scale with an ultra-short-throw engine requires a specialized ambient light rejecting screen, commonly built with microscopic lenticular ridges that absorb steep overhead ceiling reflections while redirecting the projector's upward-firing light beam directly toward audience eye level. This geometric rejection preserves deep black floor levels and image contrast even when subtle architectural accent lighting remains illuminated.

Positioned on a low console just centimetres beneath the lower screen bezel sits the Optoma CinemaX D2 laser projector. Released in September 2022 for CA$3,300, the CinemaX D2 succeeded the popular CinemaX P2 model and delivered critical hardware enhancements^[1]. The unit utilizes a 0.47-inch Texas Instruments digital micromirror device that applies four-phase XPR pixel shifting to achieve a full 3840 by 2160 4K image. Its solid-state laser phosphor light engine generates 3,000 ANSI lumens, maintaining uniform illumination across its rated 30,000-hour operational lifespan in economic mode^[1]. Projector Central evaluated the D2 and noted that it "hosts some notable improvements over its predecessor" while delivering ultra-low input lag suitable for high-frame-rate content^[1]. The chassis incorporates an internal 20-watt stereo soundbar, though dedicated home cinemas route audio over enhanced audio return channel connections directly to outboard processing gear.

Flanking the projection screen on the left and right are the Definitive Technology BP9080x bipolar tower speakers. First brought to market in 2016 at CA$4,700 per pair, each massive tower stands 50.5 inches tall, 7 inches wide, 16 inches deep and weighs 62 pounds. The BP9080x implements a forward-focused bipolar array featuring front and rear driver sets designed to project an expansive acoustic envelope into the room. Each tower integrates an active 12-inch front-firing subwoofer coupled to two 12-inch passive bass radiators, driven by an internal 455-watt Class D amplifier. Sound & Vision reviewed the system, praising its "deep, huge, larger-than-life soundstage" while demonstrating immense dynamic range^[2]. Hidden beneath the acoustically transparent aluminium top plate sits an integrated upward-firing Dolby Atmos elevation speaker, allowing height channels to operate without requiring extra external enclosures.

Directly centred under the 130-inch screen sits the Definitive Technology CS9080 centre channel speaker. Launched in 2016 at CA$1,350, the CS9080 weighs 36 pounds and measures 7 inches high, 23.1 inches wide and 14.25 inches deep. It matches the acoustic timbre of the front towers by employing two 5.25-inch balanced double surround system midrange drivers flanking a 1-inch annealed aluminium dome tweeter. Unlike standard passive centre speakers that struggle with low-frequency male dialogue resonances, the CS9080 houses an integrated 8-inch powered subwoofer and a 10-inch bass radiator driven by a 300-watt internal amplifier. Sound & Vision reported that it functions as "a dialogue powerhouse with genuine low-end authority" during dense multi-channel movie tracks^[2].

Sub-bass reproduction below 30 Hz is reinforced by heavy-duty SVS subwoofers situated along room boundaries. The flagship SVS PB16-Ultra ported subwoofer, launched in late 2016 at CA$3,499, incorporates a massive 16-inch high-excursion driver wound with an 8-inch edge-wound voice coil to withstand extreme thermal stresses^[3]. Power is delivered by a Sledge Class D discrete MOSFET amplifier producing 1,500 watts of continuous RMS power and over 5,000 watts of peak power^[3]. A 50 MHz Analog Devices digital signal processor regulates excursion, allowing bass extension to reach down to a subterranean 15 Hz in extended two-port tuning mode^[3]. Audioholics reviewed the PB16-Ultra, observing that "SVS has taken clean deep bass to another level" without audible port turbulence or mechanical distortion^[3]. Decoupling elastomer feet under the cabinet isolate these massive mechanical vibrations from shaking the architectural floor joists.

System electronics and high-current power stages are centralized in a heavy Emotiva A/V rack positioned away from primary sightlines. Housing Emotiva cinema processors and modular power amplifiers, the steel rack maintains organized cable dressing and clean power isolation. The cutaway profile displays six ceiling-mounted Dolby Atmos speakers arranged in three discrete pairs: Top Front, Top Middle and Top Rear. These downward-angled overhead speakers conform to CEDIA RP22 spatial placement windows, directing focused vertical sound objects toward listeners^[4]. The three-dimensional soundfield is completed by four ear-level surround speakers mounted along the side and rear walls, maintaining a continuous 360-degree acoustic horizon around the audience.

Specifications on the drawing

130-inch screen: A fixed-frame projection surface measuring 130 inches diagonally across a 16:9 widescreen aspect ratio. This substantial dimension establishes an immersive 40-degree field of view for viewers seated approximately 3.8 metres away.
Optoma CinemaX D2 projector: An ultra-short-throw solid-state laser projector capable of producing 3,000 ANSI lumens of brightness at 4K resolution from just centimetres away. It eliminates the need for long ceiling mounts while delivering high brightness and crisp motion clarity.
Definitive Technology BP9080x tower speakers and CS9080 centre: A matched front stage trio of floorstanding bipolar towers and a high-output centre channel speaker with integrated powered subwoofers. This configuration produces a seamless front soundstage where vocal panning and energetic sound effects maintain consistent acoustic timbre and tactile bass impact.
SVS subwoofers: Dedicated low-frequency enclosures utilizing massive high-excursion drivers and high-wattage Class D amplifiers to reproduce subterranean bass. They pressurize the room below 20 Hz, handling intense cinematic low-frequency effects that standard speakers cannot physically reproduce.
Emotiva A/V rack: A dedicated metal framework housing balanced cinema processors, modular multi-channel power amplifiers and clean power delivery modules. It consolidates heat generation, simplifies servicing access and isolates sensitive analogue preamplifier circuits from external electrical noise.
6 ceiling Dolby Atmos speakers: Three pairs of overhead speakers recessed into the ceiling structure to deliver discrete vertical height channels. These drivers establish a realistic hemisphere of sound, rendering elevated audio cues like overflying aircraft, pouring rain and room ambiance with pinpoint accuracy.
4 surround speakers: A perimeter set of side and rear surround speakers positioned at listener ear level around the seating area. They complete the horizontal audio plane, enveloping viewers in ambient environmental effects and rendering seamless directional pans from front to back.
