Rockford Fosgate PM282 Punch Marine 8" Full Range Speakers

Rockford Fosgate PM282 Punch Marine 8" 2-Way Coaxial Speakers Marine-Grade Punch, Built for the Water

Product Overview

The Rockford Fosgate PM282 is a Punch Marine 8" 2-way coaxial speaker system featuring a bridge-mounted 1" (25 mm) component-grade coated aluminium alloy tweeter and a CEA-2031 compliant 100W RMS / 200W peak power handling rating. Designed as a true marine-grade speaker system rather than a standard automotive speaker adapted for outdoor use, the PM282 is engineered from the ground up to withstand the UV radiation, salt fog, moisture, and vibration conditions of open Australian watercraft and powersport environments.

Every material and component in the PM282 has been specifically selected for marine environment durability: UV stable Centrex 814 injection-moulded plastic parts, UV and salt-fog resistant TPE surround, injection-moulded mineral-filled polypropylene cone with UV inhibitors, moisture and fatigue-resistant Aramid fibre spider, corrosion-resistant gold-plated polarised input terminals, and an 18-gauge corrosion-resistant removable stainless steel grille. The integrated 12 dB/octave sealed crossover with protection circuit, spare terminal set for optional additional tweeters, and 48 Hz 22 kHz frequency response complete a full-range marine speaker designed to perform from the dock to full throttle on Australian waterways.

Features & Benefits

• True marine-grade compliance engineered for the outdoor environment: The PM282 is not a standard coaxial speaker with a weather-resistant sticker. Every component is purpose-selected for UV, salt fog, moisture, and vibration resistance addressing the specific failure modes of speakers used in open Australian marine environments where conventional automotive speakers degrade rapidly.
• UV stable Centrex 814 injection-moulded plastic parts: Centrex 814 is a premium UV-stabilised ABS material specifically formulated to resist colour fading, brittleness, and structural degradation under prolonged UV exposure a critical requirement on Australian watercraft where direct sun exposure is constant and intense.
• UV and salt-fog resistant TPE surround: Thermoplastic elastomer (TPE) surrounds maintain their mechanical properties under UV radiation and salt fog exposure where rubber surrounds crack and foam surrounds degrade. The PM282 surround is specifically formulated for marine conditions, not repurposed from an automotive application.
• Injection-moulded mineral-filled polypropylene cone with UV inhibitors: Mineral-filled polypropylene is stiffer and more dimensionally stable than standard paper or non-filled polypropylene cones, resisting moisture absorption and UV degradation that would cause paper cones to soften and polypropylene cones to embrittle over time on the water.
• Moisture, tear, and fatigue-resistant Aramid fibre spider: Aramid (Kevlar-family) fibre spider resists moisture absorption, tearing, and mechanical fatigue maintaining consistent compliance and linear voice coil alignment across extended high-excursion use in humid and wet marine environments where standard fabric spiders would absorb moisture and change compliance characteristics.
• 1" (25 mm) bridge-mounted component-grade coated aluminium alloy tweeter: The bridge mounting positions the tweeter at the acoustic centre of the woofer for coherent time-aligned sound reproduction across the listening area. The component-grade coated aluminium alloy diaphragm delivers extended high-frequency response to 22 kHz with the corrosion resistance required for marine use.
• 100W RMS / 200W peak power handling CEA-2031 compliant: CEA-2031 is the industry standard for marine speaker power ratings. At 100W RMS with a verified compliance rating, the PM282 is accurately rated against a recognised standard not a peak-only marketing figure.
• 90 dB sensitivity @ 1W/1M: 90 dB sensitivity means the PM282 produces meaningful output from modest amplifier power important in open-air marine environments where ambient noise and wind require efficient speakers to maintain audible music levels without demanding extreme amplifier output.
• 48 Hz – 22 kHz frequency response: A wide frequency range for a coaxial marine speaker, extending lower than many comparable marine 8" speakers and covering the full audible spectrum to 22 kHz from the aluminium alloy tweeter.
• Integrated 12 dB/octave sealed crossover with protection circuit: The sealed crossover design prevents moisture ingress into the crossover network. The integrated protection circuit safeguards the tweeter against over-excursion and power surges particularly important in marine installations where amplifier gain is often set aggressively to overcome ambient noise.
• Corrosion-resistant gold-plated polarised input terminals: Gold plating resists corrosion at the terminal connection point where dissimilar metals and moisture can accelerate galvanic corrosion over time. Polarised design prevents reverse polarity connection.
• Spare terminal set for optional additional tweeters: The PM282 includes a spare terminal set allowing connection of optional additional tweeters for expanded high-frequency coverage in larger vessel installations a flexibility feature not commonly found in standard marine coaxial speakers.
• 18-gauge corrosion-resistant removable stainless steel grille: The grille protects the driver from physical damage and water ingress during high-speed operation and is removable for servicing. 18-gauge stainless steel resists corrosion in saltwater and estuarine environments indefinitely.
• Stainless steel mounting hardware: All mounting fasteners are stainless steel, preventing corrosion at the mounting point over years of saltwater exposure a common failure point with standard plated steel hardware in marine installations.
• Fully insulated flex lead wire stitched under spider: The lead wire is stitched under the spider and fully insulated, protecting it from mechanical fatigue at the spider attachment and from moisture ingress at the voice coil connection addressing a common failure mode in marine speakers subject to high-excursion and wet conditions.

Frequently Asked Questions

Are the PM282 speakers suitable for open saltwater marine use in Australia? Yes. The PM282 is built to true marine-grade compliance with UV stable Centrex 814 plastic parts, TPE surround, Aramid fibre spider, gold-plated terminals, and stainless steel hardware all specifically selected for the UV intensity, salt fog, moisture, and vibration conditions of Australian coastal and estuarine watercraft.

What is the mounting depth of the PM282? The PM282 requires 87 mm (3.4") of mounting depth. Confirm available mounting depth at your intended installation location before purchase, as marine vessel mounting locations particularly in smaller tinnies and runabouts can have restricted depth behind the mounting surface.

Why does the PM282 include a spare terminal set? The spare terminal set allows connection of optional additional tweeters to expand high-frequency coverage in larger vessel installations where a single tweeter per speaker position may not provide sufficient high-frequency dispersion across the listening area. Confirm compatible additional tweeter options with Rockford Fosgate or your supplier.

How does 90 dB sensitivity affect amplifier requirements? At 90 dB sensitivity, the PM282 produces 90 dB of output from 1 watt at 1 metre. In open-air marine environments where wind and engine noise are present, higher sensitivity means more audible output from the same amplifier power reducing the amplifier wattage needed to achieve satisfactory volume levels at the helm and seating areas.

Are the PM282 speakers available in black? The PM282 is supplied in white as standard. A black finish is noted as available confirm availability and the correct part number for the black version with your supplier before ordering.
