Rochester, NY & Whitinsville, MA – October 2021…Fulcrum Acoustic, creators of high-performance professional loudspeaker technologies, has released the AHS Series, a modular, scalable system targeted at applications where very high output and precise pattern control are required. This new series of products represents a leap forward in achieving digitally configurable coverage for long-throw applications, all within a surprisingly compact envelope.
Built for Long-Throw Applications
Long-throw applications, such as those encountered in stadium end-zone/scoreboard/video display deployments, pose unique challenges. Substantial acoustic output is required to achieve SPL targets at distance. Additionally, high-frequency air loss can be significant at stadium-scale distances. All aspects of the AHS Series products were designed with these particular challenges foremost in mind.
High Power Density
Building on the AH family of high-sensitivity, high-output systems, AHS packs a lot of output into a 36” wide x 31” tall package. AHS high-frequency sections were specifically conceived to provide the extreme high-frequency output necessary to combat air loss. Four high frequency horns (AHS440) or 3 high frequency horns (AHS460) are each paired with a coaxial compression driver; the horn stack is coaxially mounted in the mouth of a low frequency horn. The low frequency horn is driven by 4 high-power 10” woofers loaded by Oculus™ phase plugs. The Compression Head™ extends the low frequency horn length, allowing for low frequency extension to 60 Hz in a modest 28” of depth.
Optimal Coverage Patterns
There are currently two available AHS models, the AHS440 with 45° horizontal dispersion and the slightly wider AHS460 with 60° horizontal dispersion. The horizontal patterns were specifically chosen to optimize the coverage for stadium-type applications without requiring an excessive quantity of loudspeakers to cover a typical stadium horizontal footprint.
Fulcrum Acoustic’s TQ processing combined with beam-forming DSP algorithms configures AHS vertical dispersion to match a venue’s specific geometries and throw distances. The digitally steerable vertical dispersion allows the AHS to cover precise vertical angles of seating across the length of a stadium while avoiding sonic intrusion to neighboring facilities or energizing reflective surfaces.
Modular for Flexibility
The modular design allows for stacking multiple AHS speakers to create larger arrays, thereby achieving more vertical pattern control, higher output, and increased high-frequency projection. When multiple AHS units are stacked, the stack is configured as one digitally steerable array.
Compact Size
The compact dimensions of AHS enclosures allow them to be maneuvered relatively easily within cramped support structures. This is especially beneficial for addressing design challenges presented by endzone/scoreboard/video displays. The ability to seamlessly integrate AHS Series products into existing architecture make them an ideal choice for stadium applications. Their compact size has the added benefit of streamlining what can frequently be a complicated installation process.
