Description
"PROFESSIONAL HIGH FREQUENCY" SPEAKER KIT - TRI-BAND SYSTEM
Extreme Coverage
Peak on ultra-high frequencies (>10kHz) for crisp contact signals even at great distances.
Natural Crossover
Perfect overlap between speakers to cover every phase of the call without frequency “gaps”.
This configuration is specifically designed for calling small migratory birds. Combo 1: the system integrates the projection power needed for long distances with the micro-definition essential for the approach phases. By splitting the workload across three specific units, driven by the two independent channels of the DSS-RX, you can simultaneously play a rich, natural melodic background (via neodymium components) and overlay sharp, penetrating contact signals (via the piezo), creating a 3D soundscape impossible to achieve
with a single speaker.
TW-75 (Long Range)
50 Watt power unit. Designed to push sound over long distances. Manages the “range” of the call, allowing you to cover vast areas.
TW-35 (Detail)
High-fidelity neodymium driver. Its internal construction softens the sound,
eliminating harshness for natural reproduction of melodic songs.
TW-ZIP (High Freq)
Specialized piezoelectric tweeter . Works
exclusively on ultra-high frequencies (>10kHz), ensuring
that metallic edge essential for nighttime contact calls.
OPERATIONAL PHASES (Field Use)
Phase 1: Long-Range Signaling The system integrates the TW-75 unit, capable of projecting sound over considerable distances, and the TW-ZIP tweeter. The latter is calibrated to emphasize sharp metallic sounds, allowing localization even in wind or background noise.
AWAKENING AND SOCIAL ACTIVITY
Phase 2: During the morning awakening, the TW-35, thanks to its specific construction technology,
delivers smooth mid-frequencies, faithfully reproducing
social calls without the typical harshness of horns.
