The 2Ω 5.25" fairing speaker for factory-radio Harley Touring — direct replacement for front fairing and Tour-Pak® positions.

The MAS.522 is Precision Power's 5.25" 2Ω fairing coaxial for Harley-Davidson® Touring models with 5.25" speaker positions — built to extract more output from factory Boom!™ Box radio power and compatible amplifiers than the stock fitment delivers. 75W RMS, 92 dB sensitivity, polypropylene cone with Santoprene surround, 1" titanium dome tweeter. Direct-fit into factory 5.25" fairing and Tour-Pak® pods without modification. Sold in pairs.

The 5.25" fairing position appears across the Harley-Davidson® Touring range — front fairing pods and Tour-Pak® speaker positions on models from 1998 onward. Factory speakers in these positions share the same design compromises: low efficiency, inadequate thermal handling, and no real attention to the acoustic demands of riding at speed. The MAS.522 is a direct replacement that addresses all of this — without requiring amplification or any modification to the mounting location.

Who This Speaker Is For

Riders with 5.25" fairing or Tour-Pak® speaker positions who want a genuine improvement on factory radio power. The 2Ω impedance draws more current from the source at a fixed voltage — producing more acoustic output than a 4Ω replacement from the same head unit without touching the wiring or adding amplification. For amplified builds where load stability and thermal margin matter more than maximum output efficiency, the MAS.524 is the 4Ω variant.

What This Is Best For

• Maximum output from factory radio power: Ohm's law: at fixed voltage, power doubles when resistance halves. A 2Ω speaker draws twice the current of a 4Ω replacement from the same head unit — producing noticeably more volume without adding an amplifier or touching the existing wiring. The MAS.522 is the correct choice for factory-radio builds where volume and clarity matter.
• Highway-speed clarity with titanium dome tweeter: At 92 dB sensitivity and with a 1" titanium dome tweeter, the MAS.522 maintains vocal intelligibility and high-frequency detail at speeds where wind and road noise dominate. Titanium resists UV, moisture, and temperature cycling — the three things that degrade fabric dome tweeters over time in an open-air fairing environment.
• Direct-fit with no modification: The MAS.522 drops straight into factory 5.25" speaker mounting positions with no cutting, no adapter plates, and no modification to factory openings. The 50.8mm (2.0") mounting depth clears the tight spaces behind fairing and Tour-Pak® pods on Harley Touring models.
• Long-term durability in harsh conditions: Polypropylene cone, Santoprene surround, and glass fibre-reinforced ABS basket are chosen specifically for the heat, vibration, UV, and moisture that accelerate the failure of cheaper speakers in motorcycle fairing and Tour-Pak® positions.

The Bottom Line

A properly engineered 5.25" fairing and Tour-Pak® coaxial for factory-radio Harley Touring builds — 75W RMS, 92 dB sensitivity, titanium dome tweeter, and a polypropylene cone and Santoprene surround built to last in the conditions a motorcycle speaker actually faces. The 2Ω impedance extracts maximum output from the factory Boom!™ Box radio without touching the amplifier, and the drop-in fit means installation is a speaker swap, not a modification project. For amplified builds, see the MAS.524 (4Ω).

What's Inside the MAS.522

The cone is UV-resistant polypropylene, co-moulded with a low-density Santoprene surround through a chemical bonding process — not mechanical joining. Polypropylene is impermeable: road spray, humidity, and condensation do not affect its acoustic properties or structural integrity. Santoprene holds its compliance across the temperature extremes a fairing or Tour-Pak® pod creates — from cold morning starts to sustained summer heat — without the degradation that affects foam surrounds over time. On the road: the speaker's acoustic behaviour in rain or summer heat is the same as on a dry winter morning. No compliance shift, no cone sag — consistent response across the seasons.

The 1.25" (31.75mm) oxygen-free copper voice coil is wound on a thermally absorbent aluminium former. Aluminium conducts heat away from the voice coil windings faster than paper or Kapton — transferring it to the air gap and basket, where it can dissipate. The neodymium motor delivers a high magnetic flux density in a low-mass package — the field strength needed for 92 dB sensitivity without the bulk and weight of a ferrite motor. On the road: at sustained volume on a long touring day, the aluminium former keeps voice coil temperature in check — maintaining consistent power handling and output through the ride.

The tweeter is a 1" titanium dome — rigid, low-mass, and thermally stable. Titanium moves quickly and accurately at high frequencies without the breakup modes that limit softer dome materials. It resists UV degradation, moisture, and temperature cycling better than fabric domes — which soften in the heat and exposure of a motorcycle fairing over time. An integrated 6dB high-pass crossover rolls off low frequencies before they reach the tweeter, protecting it from excursion damage at high output levels. On the road: the titanium dome maintains its acoustic character through weather and seasons. The clarity you hear on the first ride is the clarity you get after three summers in the fairing.

The glass fibre-reinforced ABS basket provides the structural rigidity to handle vibration transmitted through the fairing and Tour-Pak® pod directly into the speaker frame — keeping the motor and cone assembly aligned across extended high-volume riding.

Sensitivity and Impedance

At 92 dB (1W/1m), the MAS.522 converts source power to acoustic output efficiently. In a factory-radio build where output is fixed, every decibel of sensitivity is front-stage volume you do not have to generate with more power. The 2Ω impedance compounds this: by drawing more current from the source at a fixed voltage, the MAS.522 produces more acoustic output than a 4Ω replacement at the same sensitivity — a meaningful volume increase over stock 5.25" speakers without adding an amplifier.

2Ω — What It Means for Your System

At fixed source voltage, power delivered to the speaker is determined by the speaker's impedance: halving the impedance doubles the current and doubles the power. A 2Ω speaker draws twice the current of a 4Ω replacement at the same source voltage — extracting more power and producing more acoustic output. This is the correct impedance for factory-radio builds and most compact motorcycle amplifiers. If an external amplifier is in the system in a bridged configuration, confirm impedance compatibility before ordering — bridging halves the impedance the amplifier sees, and a 2Ω speaker on a bridged channel presents a 1Ω load below the safe operating limit of most amplifiers. In that case, the MAS.524 (4Ω) is the correct choice.

Fitment

The MAS.522 drops straight into factory 5.25" speaker mounting positions on Harley-Davidson® Touring models — no modification or adapters required. Confirm your fairing pod accepts a 5.25" driver before ordering; some Touring models use 6.5" fairing positions.
