Atlas Sound AS-4T-W 4" AS Series Surface Mount (White)

Designed for Clear Audio in Compact Outdoor or Indoor Spaces
The AS‑4T‑W is a passive, surface-mount 4″ two-way speaker built to deliver crisp paging and ambient sound in commercial settings. Combining a weatherproof woofer with a high-frequency compression driver, it provides balanced sound performance ideal for retail areas, public walkways, patios, or hospitality venues where discreet, reliable coverage is required.

Engineered to Withstand the Elements with IP55 Protection
This speaker’s cabinet is made from UV-inhibiting ABS rated for outdoor environments and includes a powder-coated aluminum grille for corrosion resistance. IP55-rated for water and dust ingress, it maintains consistent sound quality and appearance even in exposed locations or high-moisture conditions.

Flexible Power Settings with Transformer Taps or Direct Drive
A built-in 60 W low-loss transformer features multiple tap settings while an integrated bypass switch enables 8-ohm direct operation. These options allow hassle-free integration into 70 V/100 V distributed systems or standard low-impedance amplifiers—perfect for installers working with mixed environments.

Wide Dispersion Pattern for Even Coverage
The speaker uses a custom-engineered waveguide to provide broad coverage—120° horizontally and 100° vertically. This wide pattern ensures uniform sound delivery across large audience areas, reducing hot spots and improving speech clarity in applications like paging systems or background audio zones.

Versatile Mounting That Simplifies Installation
Included slip-resistant U-bracket mounts support vertical or horizontal installations and allow for pan and tilt adjustments. Multiple 1/4″‑20 threaded inserts provide alternative mounting points on poles, ceilings, or walls. This flexibility enables accurate aiming for best sound placement and speedy installation.

Seamless Integration with AS Series Ecosystem
AS‑4T‑W shares its acoustic tone, mounting fittings, and aesthetic with other AS Series models. This ensures cohesive appearance and performance when deploying speaker systems across different sizes—from full-range models to subwoofers—without visual or functional mismatch.

Commercial Durability Built to Industry Standards
This speaker is UL1480A rated and meets MIL‑STD‑810 criteria for environmental resistance. It’s designed for long-term durability and low maintenance in demanding commercial environments, offering full-range sound performance with minimal distortion.
