Cicada Audio RR3WG-65F 6.5-inch Flat Acoustic Waveguide

The compact 6.5-inch flat waveguide for RR2TM & RR3TM motors — fairing, inner pod, and tight-space horn-loaded performance where a 6×9" won't fit

The Cicada Audio RR3WG-65F is a 6.5-inch flat acoustic waveguide for Cicada Audio's RR2TM and RR3TM compression driver motors. Sold as a pair, it brings horn-loaded high-frequency performance to fairing positions, inner pods, lower fairing locations, and custom enclosures where the larger 6×9" waveguide formats won't fit. Same precision throat geometry, same all-weather composite construction, same Nanofram™ compatibility — in a compact footprint built for the front stage of a touring bike.

The RR3WG-65F is the fairing-position complement to the 6×9" saddlebag series. Where the RR3WG-69F, RR3WG-69A, and RR3WG-69S are built around a standard 6×9" cutout for bag lid positions, the RR3WG-65F works with the 6.5-inch cutout geometry of fairing and inner pod positions — giving riders who want a fully horn-loaded system front and rear the matching waveguide for the front stage.

Who This Is For

Riders building a front-stage horn system in fairing or lower fairing positions, or anyone running the RR2TM or RR3TM in a position where a 6×9" cutout isn't achievable but a 6.5-inch opening is. This is the correct waveguide for Street Glide and Road Glide fairing positions, lower fairing speaker positions, inner pod installs, and any custom enclosure built around a 6.5-inch cutout. If your install is a standard saddlebag lid, start with the 6×9" series — the RR3WG-69F for full-depth flat positions or the RR3WG-69S for depth-constrained lids.

What This Is Best For

• Fairing and lower fairing positions — horn loading where it's rarely done — Most fairing and lower fairing installs run bare dome tweeters or coaxial speakers with no waveguide. Putting a compression motor behind a horn waveguide in a fairing position produces dramatically more output per watt and far more controlled dispersion than any dome tweeter alternative. On the road: the front stage transitions from background high-frequency fill to a genuine high-SPL horn system that projects clearly over highway wind — the kind of front-of-stage presence that makes the full system sound coherent.
• Compact 6.5-inch format — fits where 6×9" cannot — Fairing speaker positions on Harley-Davidson Touring bikes are built around a 6.5-inch cutout, not a 6×9". The RR3WG-65F is engineered for this format — the same horn-loading principle as the larger series, in a footprint that actually fits the available space without modification. On the road: a horn-loaded front stage running RR3WG-65F waveguides in the factory fairing cutouts, no additional fabrication required.
• Wide dispersion from a close-range listening position — Fairing-mounted speakers are physically closer to the rider's helmet than saddlebag positions. At close range, controlled dispersion matters more than maximum throw — the horn geometry produces a broad, natural soundstage without harsh on-axis peaks when the rider is directly in front of the waveguide. On the road: clean, even high-frequency coverage from the front stage that integrates naturally with the rear stage rather than creating a hard, directional hot-spot at the rider's ear level.
• High SPL output in a compact footprint — Despite the smaller face area compared to the 6×9" and 8-inch waveguides, the 6.5-inch horn delivers genuinely high SPL from either the RR2TM or RR3TM motor. The horn-loading efficiency advantage over a dome tweeter applies regardless of horn mouth size — more output per watt than any conventional alternative in the same position. On the road: fairing-position highs that keep up with a properly driven mid/bass stage, without needing to run the system at extreme amplifier output to compensate for inefficient tweeter placement.
• Precision-matched throat geometry for RR2TM & RR3TM — Throat dimensions are engineered to the exit diameter of both the ferrite RR2TM and neodymium RR3TM motors, ensuring correct acoustic loading for both in the 6.5-inch horn profile. On the road: run the RR2TM now and upgrade to the RR3TM later — the waveguide loads correctly with both motors, no crossover or EQ changes required between motor types.
• Efficiency-optimised internal wave path — Smooth internal flare geometry minimises acoustic turbulence and internal reflections that produce colouration and distortion at high output levels. A well-designed horn performs cleanly under sustained high-volume conditions — exactly what a front stage running at touring speed needs. On the road: the output stays clear and detailed at sustained high volume rather than developing the hardness that appears when compression drivers are pushed through a poorly-designed horn profile.
• All-weather composite construction — Built from UV-stable, moisture-resistant composite materials designed for powersports environments. Fairing positions see direct sun, temperature cycling from engine heat, and road debris — the RR3WG-65F is built to withstand all of it without dimensional change or acoustic degradation. On the road: no warping from heat, no cracking from vibration, no rattles — consistent acoustic performance over the long term.
• Nanofram™ compatible — Accepts Cicada Audio's Nanofram™ horn cover for additional weather protection and a clean, finished appearance. On the road: add Nanofram™ for exposed fairing positions or high-moisture environments — the composite housing provides sufficient protection for normal conditions, Nanofram™ adds the extra layer for demanding installs.

The Bottom Line

The RR3WG-65F brings horn-loaded front-stage performance to fairing and lower fairing positions — the part of a touring bike build that most systems never upgrade beyond bare dome tweeters. Pair it with the RR3TM for maximum sensitivity and power handling, or the RR2TM for a capable and cost-effective front stage. For riders building a fully horn-loaded system front and rear — RR3WG-65F in the fairings, any RR3WG-69 format in the bags — this is the waveguide that completes the front stage.

Fitment

The RR3WG-65F uses the same horn-loading principle as the full Cicada waveguide range — converting the narrow, high-pressure exit of a compression driver into a broad, controlled, highly-efficient radiated signal. The 6.5-inch format is the compact expression of this principle: sized for fairing and inner pod positions rather than bag lids or Tour-Pak enclosures, but delivering the same acoustic advantages — dramatically higher efficiency than a dome tweeter, controlled directional output, and consistent performance at high volume levels.

On the road: a compression driver behind a properly-matched 6.5-inch horn waveguide produces more high-frequency output per watt than a dome tweeter could manage with twice the amplifier power — in a mounting position that most riders already have available in the front fairing.

6.5-inch Horn Geometry

The 6.5-inch profile is a deliberate engineering choice rather than a compromise. Fairing-position listeners are physically closer to the speaker than saddlebag-position listeners — the horn mouth area required to produce excellent SPL at close range is less than what's needed for the long-throw projection of a Tour-Pak or bag lid position. The RR3WG-65F is sized to deliver the appropriate coupling efficiency and dispersion pattern for fairing-to-helmet distances, which means a controlled, even output at the rider's ear rather than the hotspot harshness that can develop when a large, high-throw horn is used at very close range.

On the road: the front stage delivers clean, natural high-frequency presence that integrates with the rear stage — not a harsh, directional beam aimed at the rider's left ear from a metre away.

Throat Geometry & Motor Compatibility

The throat is precision-matched to the exit diameter of both the RR2TM (2-inch ferrite) and RR3TM (3-inch neodymium) compression motors. Correct throat geometry loads the motor within its optimal operating range — too tight and the motor is over-damped, too loose and coupling efficiency drops. The RR3WG-65F geometry achieves correct loading for both motor formats, ensuring consistent output and frequency response regardless of which motor is in use.

On the road: whether the front stage is running RR2TM or RR3TM motors, the waveguide loads correctly — consistent crossover points, consistent frequency response, and no distortion artefacts from mismatched acoustic impedance.

Dispersion: Front-Stage Optimised

At fairing-to-rider distances, wide horizontal dispersion with controlled vertical output is the correct pattern — you want even coverage across a broad arc (covering rider and passenger in a natural way) without excessive energy going to the footpegs or the sky. The RR3WG-65F's horn geometry is designed for this: broad horizontal spread that integrates well with the rear bag lid or Tour-Pak stage, controlled vertical output that keeps the energy in the listening zone. The result is a front stage that adds clarity and imaging rather than hotspot harshness.

On the road: the front stage sounds like it's in front of the rider — a natural soundstage rather than two isolated point sources, one for each fairing speaker.

Internal Wave Path

The smooth internal flare geometry follows an optimised path from throat exit to horn mouth, minimising the turbulence and internal reflections that generate colouration and distortion in the radiated output. For a compression driver operating in the 3kHz–20kHz range, the acoustic path geometry at the horn has a direct effect on the distortion character and frequency response linearity at the output face. The RR3WG-65F's flare profile maintains smooth pressure distribution across the mouth face for consistent, low-distortion output at any volume level.

On the road: the front stage stays clean and accurate at sustained high-volume touring — no upper-midrange harshness developing as the session goes on, no fatigue from distortion peaks at specific frequencies.

All-Weather Composite Construction

Moulded from UV-stable, moisture-resistant composite materials formulated for powersports durability. Fairing positions on a touring motorcycle see direct solar radiation, engine heat from the fairing cavity, vibration from the engine and road, and rain. The composite material maintains its dimensional accuracy through this environment — essential for a horn, where geometry is performance.

On the road: acoustically and structurally consistent across the full range of Australian touring conditions — no warping from fairing heat in summer, no cracking from cold starts in winter.

Nanofram™ Compatibility

Fully compatible with Cicada Audio's Nanofram™ horn cover system. Nanofram™ provides a physical barrier at the horn mouth against direct water ingress and debris while having minimal effect on the acoustic output in the motor's operating frequency range. For fairing positions that see regular rain splash or high-pressure washing, Nanofram™ provides the additional protection layer beyond the all-weather composite housing.

On the road: add Nanofram™ for particularly exposed installs or regularly wet environments — the acoustic performance difference at high frequencies is minimal, and the physical protection from direct water contact is real.
