Hertz SV 165.1 — High-Efficiency 6.5″ SPL Midrange for Harley Front Stages
The Hertz SV 165.1 is a purpose-built 6.5″ SPL midrange designed for riders building serious multi-amp, multi-speaker front stages. With exceptional sensitivity, a powerful ferrite motor, and a wide mid-focused bandwidth, this driver delivers forward, detailed vocals that stay clear even when the bike — and the volume — are wide open.
Key Features
- Dedicated SPL midrange driver designed for high-output motorcycle audio systems.
- 97 dB sensitivity ensures exceptional clarity with minimal amplifier power.
- 100–10,000 Hz performance covering the critical vocal and instrument band.
- Rigid pressed-paper cone tuned for natural, accurate midrange at high levels.
- Ferrite magnet assembly for strong motor force and reliable long-term performance.
- Double-wave treated surround improves excursion and reduces distortion.
Why It Works on Harleys
- Strong vocal projection — ideal for fairing-based front stages where clarity is key.
- High efficiency makes the most of amplifier power and cuts through wind and exhaust noise.
- Perfect for active systems where tweeters and woofers are driven separately.
- Recommended for serious builds running DSP and dedicated amplification.
Recommended System Use
- Amplifier Power: 100–150 W RMS
- High-Pass Filter: 100–120 Hz @ 12–24 dB/octave
- Low-Pass Filter: 3,500–5,000 Hz when paired with dedicated tweeters
- Note: This is a midrange-only driver. Separate tweeters are required.
Fitment
- Ideal for Harley-Davidson Touring fairings (Street Glide, Road Glide, Ultra)
- Best suited to custom or semi-custom builds with DSP integration
- Works in upper fairing pods, lower fairings, and custom pods with correct mounting depth
