Application Notes
Learn about speaker setup, acoustic design, subwoofer FAQs, and choosing the right speaker for your space. This collection of articles will teach you the essentials of sound application.
Temporal Equalization—TQ™
Our proprietary Temporal Equalization (TQ) technology improves loudspeaker performance by eliminating horn reflections and other artifacts of compact coaxial systems, extending the usable frequency range of high-efficiency folded bass horns, and by improving the sonic character of compression drivers.
Passive Cardioid Technology
Unlike active cardioid systems, our patented passive cardioid technology does not require additional amplifier channels, drivers or enclosure volume to achieve the cardioid effect.
Building a Better Coax
Fulcrum Acoustic is the only loudspeaker manufacturer to offer a comprehensive line of coaxial solutions incorporating multiple driver sizes and horn patterns.
Compression Head™/Oculus™ Phase Plugs
Each AHC/AHS horn-loaded woofer is loaded by one of our proprietary Oculus Phase Plugs. The output of multiple woofers is acoustically combined via the Compression Head.

Under the Hood with Fulcrum
Birch Enclosures
We use void-free, exterior grade Birch plywood for our enclosures. Birch plywood has more plies than domestic plywood, making it stiffer and more stable. The resulting enclosures are strong, with superior acoustical performance. Impact resistance is good; products can take more abuse with less surface damage.
Concealed Mounting Points
Installation products incorporate steel mounting angles engineered into the enclosures. Threaded points accept M6 or M10 bolts, depending on size and weight of the product. Up to 16 points are provided per product, thereby accommodating a variety of mounting configurations
Materials Selection for Acoustics
We have all horns, waveguides and other acoustical parts manufactured to our specifications. We carefully select plastics and urethane formulations based on their acoustical properties to minimize vibration and resonances.
Craftsmanship
Our enclosures are built by expert woodworkers who have years of experience in loudspeaker fabrication. This ensures that the complex designs are precisely executed with careful attention to every joint, seam and detail.
Tuning and Voicing
During the design process, we meticulously measure and audition drivers, crossovers and enclosures to assess sonic performance. Our testing includes laboratory measurements with our proprietary measurement software, as well in-situ (field) evaluations. Our goal is to provide a consistent, neutral voicing across the entire product line.
Premium Transducers
We work closely with the finest professional transducer manufacturers around the world. Key components have unique construction attributes for our specific needs.
Superior Weather Resistance
Our Weather Resistant (WR) enclosures are manufactured from composite materials which provide superior weather resistance in a significantly lighter-weight package. Our WR Series loudspeakers also feature a three-step zinc plating and powder coating process, stainless steel mounting hardware and weatherized woofer cones, which together enhance resistance to weather, scratching and rust.

Connectors
We use only premium, name-brand connectors for long life and reliable performance.
