The Dynacord F18 PWH is an 18-inch high-performance subwoofer featuring a Planar Waveguide™ horn design, primarily used for long-throw bass applications in live sound reinforcement. It is known for its ability to deliver deep, penetrating bass over long distances, making it a staple in medium-to-large-scale touring systems.
Build and Protection:
- Cabinet Material: Built from 18 mm poplar plywood for durability and weight reduction.
- Internal Protection: Features thermo-switches and a 4-way halogen lamp protection system to shield the 18″ chassis from thermal overload and critical power levels.
- Portability: Equipped with 4 handle trays on the sides for safe transport and 4 large-sized rubber feet for a stable stand.
- Finish: The surface is finished in an extremely resistant black-mottled needled felt.
Performance Characteristics:
- Directivity: Reviewers note that the Planar Waveguide™ design provides superior directivity in the mid-bass range, which is essential for “long-throw” performance.
- Sweet Spot: User reviews on Audiofanzine mention that while the bass may not feel optimal at 1 meter, it becomes “breathtaking” and “monstrous” at distances of 3 meters or more.
- Crossover Recommendation: For optimal integration with Mid-Hi cabinets, Dynacord recommends an active crossover frequency of 125 Hz using an 18 dB/Oct. Butterworth filter.
