Da-Lite DL15695L 174" Tensioned Advantage with SightLine Ultra-Wide Projection Screen (HD Progressive 1.1 Perf)

Product Overview

The Da-Lite Tensioned Advantage with SightLine 174" 21:9 Ultra-Wide Projection Screen (DL15695L) with HD Progressive 1.1 Perf surface is a ceiling recessed 21:9 ultra-wide projection screen engineered for installations where front-channel audio must be positioned directly behind the viewing surface. This Da-Lite SightLine floating screen commercial AV product features an acoustically transparent, micro-perforated 1.1 gain surface that allows sound to pass through without meaningful audio degradation. The HD Progressive 1.1 Perf surface is required when center-channel or LCR speaker systems must be placed behind the screen, eliminating the need for off-screen speaker arrays in large boardrooms and auditorium-style conference spaces. Specify this UL Plenum rated ultra-wide projection screen for facilities where acoustic performance and projection image quality must coexist on the same surface.

Product Description

The Da-Lite Tensioned Advantage with SightLine is a ceiling-recessed electric projection screen engineered for commercial AV installations requiring architectural integration and high performance. At 174" diagonal in 21:9 ultra-wide format (approximately 79" H x 148" W viewing surface), this screen provides a large-format solution for boardrooms, auditoriums, and large multi-purpose conference spaces. The SightLine cable-drop system replaces traditional black drop fabric with 3-4 thin cables, creating a floating screen appearance and enabling variable vertical positioning within a 70"/180cm range after installation—providing open space above the viewing area for speaker placement without requiring additional ceiling openings. The two-stage installation process installs the case during rough-in construction and completes the surface assembly during the finish phase. The 21:9 ultra-wide format supports hybrid video conferencing and presentation applications requiring a wide-format surface. The HD Progressive 1.1 Perf micro-perforated surface allows LCR and center-channel speakers to be mounted directly behind the screen, delivering on-axis audio with no physical separation between the sound source and image. The 1.1 gain white surface provides broad compatibility with commercial projectors while the acoustic perforation pattern is engineered to minimize visible impact on the projected image. TruGuide electric tensioning maintains uniform surface tension across the full 148" viewing width. Smooth Roll Technology protects the perforated surface during retraction cycles. Low Voltage Control (LVC) integrates with all major AV control systems. The UL 2043 Plenum Rated aluminum case meets commercial building code requirements. This Da-Lite commercial projection screen installation is backed by a 5-year limited warranty.

Key Features

• SightLine Cable-Drop System — Replaces black drop fabric with 3–4 thin cables, creating a floating screen appearance and allowing variable vertical positioning up to 70" from ceiling to screen top edge.
• 21:9 Ultra-Wide Format — Designed for hybrid video conferencing solutions displaying in-room and remote participants simultaneously on a single surface.
• Two-Stage Installation — Case installs during rough-in construction; surface assembly during finishing stage, reducing coordination requirements between trades.
• TruGuide Electric Tensioning System — Maintains uniform surface tension across the full viewing area to eliminate wrinkles and surface distortion.
• Smooth Roll Technology — Prevents surface deformation during retraction cycles, maintaining flat viewing surface over the product’s service life.
• Standard Low Voltage Control (LVC) — Integrates with third-party AV control systems via dry contact relay without requiring high-voltage switching at the control point.
• UL Plenum Rated Case — Approved for installation in plenum air spaces per UL 2043, meeting commercial building code requirements in most jurisdictions.
• Ceiling Trim-in-Place Design — White powder-coated aluminum case with closure door conceals the ceiling opening; no additional trim work required after screen installation.
• HD Progressive 1.1 Perf Acoustically Transparent Surface — Micro-perforated 1.1 gain surface enables LCR and center-channel speaker placement directly behind the viewing area; required for on-axis audio in large-format AV systems.
• Seamless Viewing Surface — No center seam; maintains visual continuity across the full 174" ultra-wide viewing area.

Typical Applications

• All-hands rooms and large conference facilities deploying hybrid video conferencing
• Boardrooms requiring a premium ceiling-recessed projection solution with integrated audio
• Multi-purpose rooms configured for video collaboration with on-axis speaker systems
• Corporate training rooms with ceiling-recessed AV infrastructure and behind-screen audio
• Government conference spaces with architectural ceiling and audio requirements

Frequently Asked Questions

Q: What is the SightLine feature and how does it differ from standard black drop?

A: SightLine replaces the traditional black fabric drop above the screen with 3–4 thin cables. This creates a floating screen appearance, allows the vertical position of the screen to be adjusted within a 70" range after installation, and provides open space above the viewing area for camera or speaker placement—without cutting additional ceiling openings.

Q: Is this screen compatible with standard AV control systems?

A: Yes. The standard Low Voltage Control (LVC) integrates with Crestron, AMX, Extron, QSC, and other control systems via dry contact relay. Optional RS-232 (SCB-100/SCB-200) and screen trigger (Video Projector Interface) configurations are also available. Contact our team at creationnetworks.net for integration assistance.

Q: What projectors are compatible with the HD Progressive 1.1 Perf surface?

A: The HD Progressive 1.1 Perf is compatible with most commercial DLP, LCD, and laser projectors. The micro-perforation pattern is engineered to minimize visible impact on the projected image while allowing center-channel and LCR speaker systems to be placed directly behind the screen.

Q: Can this screen be installed in a plenum air handling space?

A: Yes. The case is UL 2043 Plenum rated, meeting the requirements for installation in HVAC plenum return air spaces as required by the International Building Code (IBC) and NFPA 90A in commercial construction.

Q: What is the two-stage installation process?

A: During the rough-in construction phase, the screen case and mounting brackets are installed and the ceiling is closed. The surface assembly is then installed during the finish phase after painting and ceiling tile work is complete. This eliminates coordination issues between the screen installer and other trades.

Q: What warranty does Da-Lite provide on this product?

A: Da-Lite provides a 5-year limited warranty covering manufacturing defects. For warranty service or technical support, contact Creation Networks at creationnetworks.net.
