Premium Low-Frequency Performance
The FC-8ST is purpose-built to extend the low-frequency capability of AtlasIED IsoFlare™ ceiling loudspeaker systems. Delivering deep, powerful bass response with exceptional clarity and control, the subwoofer enhances music playback while providing greater system headroom for demanding commercial audio applications.
Its optimized acoustic design makes it an ideal choice for hospitality venues, corporate environments, upscale retail spaces, educational facilities, houses of worship, and other installations where premium sound quality is a priority.
Designed to Complement the IsoFlare™ FC Series
The FC-8ST has been specifically engineered to integrate seamlessly with the AtlasIED FC Series premium ceiling loudspeakers. Matching acoustic characteristics and visual aesthetics allow system designers to create high-performance distributed audio solutions with consistent sonic performance throughout the installation.
Combined with FC-6T and other IsoFlare™ loudspeakers, the FC-8ST delivers a balanced and immersive listening experience with enhanced low-frequency extension and musical impact.
High-Excursion 8-Inch Driver
At the heart of the FC-8ST is a high-excursion 200mm (8-inch) woofer that provides authoritative bass reproduction while maintaining accuracy and low distortion. The driver utilizes a weatherized multi-fiber paper pulp cone paired with a durable butyl rubber surround to achieve excellent transient response, reliable performance, and long-term durability.
This robust driver design allows the subwoofer to perform consistently across a wide range of commercial audio applications and environmental conditions.
Integrated Passive Low-Pass Filter
A carefully engineered second-order passive low-pass filter with a crossover point of 140Hz ensures smooth integration with compatible full-range loudspeakers. This optimized crossover design helps maintain natural tonal balance while improving overall system performance and providing seamless bass reproduction.
The result is a cohesive soundstage with enhanced low-frequency presence and improved overall audio quality.
Wide and Consistent Coverage
The FC-8ST provides a nominal coverage angle of 180 degrees, ensuring broad low-frequency distribution throughout the listening environment. This wide coverage characteristic allows fewer subwoofers to effectively support larger areas while maintaining consistent bass performance across the space.
The design is particularly effective in distributed audio systems where uniform coverage is essential.
Flexible 70V/100V and Low-Impedance Operation
The integrated full-bandwidth, low-insertion-loss transformer allows the subwoofer to be utilized in distributed 70V or 100V systems while also supporting traditional low-impedance operation. The easily accessible rotary selector switch provides fast configuration during installation and commissioning.
- 60W transformer tap
- 30W transformer tap
- 15W transformer tap
- 7.5W tap (70V operation)
- 8-ohm low-impedance operation
This flexibility enables the FC-8ST to integrate into a wide variety of commercial audio system designs.
AtlasIED Atmosphere Optimization
System performance can be further enhanced using the AtlasIED Atmosphere DSP platform. Enhanced voicing presets allow designers and integrators to optimize bass performance and tuning, ensuring seamless integration with the broader FC Series loudspeaker ecosystem.
This capability simplifies deployment while helping achieve consistent audio performance across different installation types.
Architectural Aesthetics
The FC-8ST features a bezel-less grille design that blends discreetly into modern architectural environments. The grille is magnetically secured and includes a removable logo, providing maximum installation flexibility and a clean finished appearance.
The design also supports a simple one-step painting process when color matching is required, eliminating the need for additional adapters or accessory components.
Fast and Secure Installation
Installation is streamlined through AtlasIED's patented toolless high-travel secure-clamp mounting mechanism. This innovative system provides fast, secure mounting while significantly reducing installation time.
Each FC-8ST is supplied with both a C-Ring and tile bridge, providing added support and stability for suspended ceiling installations.
Durable Construction
The subwoofer utilizes an optimally tuned injection-molded front baffle constructed from UV-resistant, weather-resistant UL94V-0 rated ABS material. This rugged construction ensures long-term reliability and consistent performance in demanding commercial environments.
The combination of premium materials and advanced engineering makes the FC-8ST a dependable solution for professionally installed audio systems.
