Performance Specs
• Designed for clear vocal presence and smooth highs at high listening volume.
• High-sensitivity design allows strong output even on compact Class D amplifiers.
• Midrange chambering reduces reflections and improves articulation and detail.
• Ideal for motorcycle fairing mounts where rider-forward clarity is critical.
Key Features
• Compact Mid + Tweeter Module – Perfect for tight fairing and dash installs.
• Silk Dome Tweeter – Smooth, controlled high-frequency delivery.
• Damped Vocal Midrange – Focused clarity without harshness.
• High Efficiency (94 dB) – Plays loud with less amplifier strain.
• Integrated Crossover – Simplifies wiring while preserving tonal accuracy.
• ESB Sonic Signature – Natural, real, dynamic.
Performance Integration Notes
• Ideal Amplifier Power: 125–200 W RMS per channel.
• Recommended High-Pass Filter: 160–200 Hz (protects and sharpens vocal clarity).
• Best Use: Harley-Davidson® fairings, UTV dash pods, competition soundstage upgrades.
• Installation Time: ~30–60 minutes based on mounting surface.
Pro Tip:
Aim the tweeter waveguide toward the rider’s ear path—not just forward—to dramatically improve imaging and vocal focus at highway volume.
