Each speaker in this 4-pack handles up to 195 watts of peak power and 65 watts RMS, paired with a 2-way coaxial layout that combines a polypropylene woofer with a titanium dome tweeter. Frequency response runs from 35Hz to 21,000Hz at a 90dB sensitivity spec and a 4-ohm impedance per voice coil, tuned for open-air marine listening rather than a sealed cabin.

• Peak power handling: 195 watts; RMS: 65 watts per speaker
• Frequency response: 35Hz to 21kHz, 4-ohm impedance
• 2-way coaxial design with a titanium tweeter and polypropylene woofer

These are built as OEM-style replacements for standard 6.5-inch marine speaker openings, with a top-mount depth of roughly 2-7/8 inches, and are shaped to fit directly into KICKER KM enclosures on boat towers. Because cutout size, mounting depth, and screw pattern vary between boat models, checking the existing opening before ordering is the deciding factor in a clean swap.

• Confirm the boat's existing cutout diameter and mounting depth before installing
• Speakers ship as four units (two pairs), enough for a typical bow-and-stern setup
• No grille trim ring or wiring harness is included beyond the speakers themselves

The white grilles and cabinet are built with water-resistant construction intended for spray, rain, and sun exposure typical of pontoon, deck boat, and fishing boat use. That water resistance is rated for open-air marine exposure rather than full submersion, so the speakers are not intended for underwater mounting or direct pressure washing during cleanup.

• Water-resistant grilles and cabinet suit open-deck marine environments
• Not rated for submersion or high-pressure washing
• White finish is designed to match light-colored boat interiors and towers

Each pair delivers 320 watts peak and 160 watts RMS across two 6.5-inch 2-way coaxial drivers, with a 1-inch silk dome marine-grade tweeter mounted directly on top of the mid-woofer for a seamless crossover point. Sensitivity is rated at 88 dB into a 4-ohm load, so the speakers reach reasonable volume without demanding a high-power marine amplifier.

• 320W peak / 160W RMS power handling per pair suits mid-power marine head units and amps
• 1.2-inch SV voice coil manages heat during sustained outdoor use
• 57 Hz to 20 kHz frequency response covers most of the audible range from one driver

Because the tweeter sits atop the mid-range rather than beside it, imaging stays consistent whether the speakers are mounted in a hull, tower, or dash.

Mounting depth is 3.25 inches with a 5.75-inch cutout diameter and a 7-inch outside diameter, dimensions worth confirming against an existing speaker opening before ordering. The marine housing wraps around the driver for extra protection while helping the mid-range portion move more air for fuller sound.

• 5.75-inch cutout diameter matches many factory marine speaker openings
• 6.10-inch bolt hole circle diameter lines up mounting screws without redrilling in many installs
• 4.25-inch overall height keeps the driver low-profile once mounted

Because these dimensions are marine-industry standard sizes, the pair is intended as a direct swap for many stock boat, UTV, or ATV speaker locations rather than a custom-fit installation.

Built specifically for harsh marine environments, the speakers use a microfiber composite mineral-filled mid-woofer cone paired with a butyl rubber surround rather than the foam surrounds found on standard indoor speakers, which resists cracking and water absorption over time. The tweeter's marine-grade housing is designed to handle sun, salt air, and moisture exposure on a boat, UTV, or motorcycle.

• Butyl surround resists the stretching and drying that foam surrounds develop in humid or wet conditions
• Marine-grade housing on the tweeter and mid-woofer targets sun and moisture exposure specifically
• Sold in black, a neutral finish that matches most marine and powersport interiors

Because the pair is engineered around marine materials rather than adapted from an indoor design, it is suited to being mounted somewhere exposed to weather rather than only in an enclosed cabin.

Each speaker measures 2.125" x 6.875" (D x W) with an approximate 6.5-inch driver diameter, handling up to 140W of maximum power and 65W RMS. The dual cone design with a magnet built for high frequencies keeps sound clear at varying volumes.

• Impedance: 4-ohm, compatible with most marine and vehicle head units
• Power handling: 140W max / 65W RMS
• Driver type: dual cone for extended frequency response
• Overall dimensions: 17"D x 15.25"W x 9.75"H including mounting hardware

Sound output still depends on the connected head unit or amplifier's power delivery.

Built for marine use, these speakers carry an IPx5 water resistance certification and use a magnet made from polypropylene and ferrite to resist saltwater corrosion and UV exposure over time.

• Water resistance: IPx5-rated for splash and spray exposure
• Magnet material: polypropylene and ferrite for corrosion resistance
• UV resistance: constructed to withstand sun exposure on open boats or vehicles
• Certified for marine use, extending suitability to ATVs, UTVs, and golf carts

IPx5 covers splashing water but is not a full submersion certification, so speakers still need mounting away from direct waterline contact.

The removable grille allows repainting to match a boat, ATV, or golf cart's existing color scheme, while front or rear mounting flexibility adapts to different dash or panel layouts.

• Mounting: front or rear mount options depending on available space
• Grille: removable and paintable for a customized look
• Compatible platforms: boats, ATVs, UTVs, snowmobiles, golf carts, and coolers
• No built-in amplifier, so output depends on the connected marine stereo

Because these are passive speakers, pairing with a marine-rated head unit or amp is necessary to drive them at their full rated power.

Power handling comes in at 300W peak with 100W RMS continuous at 4 ohms.

• 40-22kHz frequency response range
• 300W peak power handling, 100W RMS continuous at 4 ohms
• Built-in crossover splits high and low frequencies between the tweeter and woofer

Dynamic Balance technology, proprietary to Polk, uses laser imaging during design to identify material combinations that reduce resonance, aimed at a cleaner, less distorted sound output.

These speakers carry IP56 marine certification, meaning they're tested against salt-fog, UV exposure, and humidity for use in boats, motorcycles, ATVs, and other exposed installs beyond standard car audio. Coated steel driver baskets add corrosion resistance compared to uncoated steel found in non-marine speakers.

• IP56 marine certification for splash and moisture resistance
• Tested against salt-fog, UV, and humidity exposure
• Coated steel baskets for corrosion resistance in outdoor and marine installs

IP56 covers protection against water jets and dust, not full submersion, so these are suited to open-boat and exposed-deck installs rather than fully underwater mounting locations.

The woofer is sized to fit both standard 6.5-inch and 6-3/4-inch mounting openings, which covers more replacement scenarios than a single fixed cutout size, and mounting hardware plus grilles are included in the box. Grilles are styled for a finished look in car door panels or marine installs where the speaker face is visible.

• Fits both 6.5-inch and 6-3/4-inch mounting openings
• Mounting hardware and grilles included for installation
• Black grille finish suited to both car and marine interior styling

As coaxial 2-way speakers, these are designed as a direct upgrade over stock door or marine speakers rather than as part of a component speaker system with separately mounted tweeters.

Each speaker in this pair handles 200 Watts RMS and 400 Watts peak power, driven by a 20 oz magnet across an 85Hz-20kHz frequency response at 4 ohms impedance for full 2-way stereo sound.

• 90dB sensitivity spec supports clear output at moderate amplifier power
• 1-inch aluminum voice coil handles sustained power without excess heat buildup
• 2-way design splits frequency response across dedicated drivers for fuller range than a single-driver speaker

Because these are passive speakers rather than powered units, they need to be wired to a compatible marine amplifier or head unit to actually produce sound.

The speakers use a universal standard OEM replacement size, with a 2.48-inch mounting depth and a 5.31-inch cutout diameter, along with complete wiring and mounting hardware included in the box.

• Low-profile design fits shallow mounting locations on boats and other vehicles
• Universal cutout size matches many factory marine speaker openings
• Wiring and mounting hardware are included, reducing extra parts to source

Because the mounting depth is shallow at 2.48 in, these speakers fit tighter installation spots than deeper aftermarket speakers, though checking the exact cutout against the existing opening first avoids a mismatch.

Built for marine and outdoor use, the speakers combine a polypropylene cone with a butyl rubber surround and a heavy-duty molded ABS plastic basket and grill, aimed at resisting water splashes, humidity and sun exposure over time.

• Fully waterproof construction suits open boats and other exposed vehicle installations
• ABS basket and grill construction resists sun-related degradation better than untreated plastics
• Butyl rubber surround resists hardening and cracking from repeated moisture exposure

This weather-resistant build makes the pair suited to permanent outdoor or marine mounting rather than an indoor speaker adapted for occasional outdoor use.

This pair handles 900W peak / 200W RMS combined (450W peak / 100W RMS per speaker), built around a 2-way design pairing a 1-inch PEI tweeter with an 8-inch woofer for balanced sound across music and vocals. Frequency response spans 40Hz-20kHz with an 89dB sensitivity spec for clear output even over engine or wind noise.

• Beat-Sync LEDs flash red or blue in time with music intensity, powered through the existing speaker wire
• 2-way driver layout splits highs and lows between dedicated tweeter and woofer components
• No separate amplifier is included, power handling figures assume a matched external amp or source

Suited to boats and ATVs wanting louder, clearer sound than stock marine speakers typically deliver.

Sealed to IP66 against both salt and fresh water, these speakers are built for marine environments rather than adapted from indoor designs. A UV-treated cone resists sun degradation, while stainless steel terminals hold up against the corrosion that standard metal contacts suffer near saltwater.

• Molded ABS housing adds another layer of protection against the elements on an open boat or ATV
• Polypropylene cone material resists moisture absorption better than paper-based cones
• Weatherproofing depends on grilles and mounting hardware being installed correctly per the included instructions

Built specifically for boats, yachts, ATVs, and other outdoor vehicle applications rather than general indoor use.

Installation calls for a 6.89-inch cutout and 3.54-inch mounting depth, dimensions worth checking against existing marine speaker locations before ordering. The included kit covers 16.4 ft of speaker wire, stainless steel mounting screws, and black grilles, so most installs need no extra parts.

• Beat-Sync LED wiring runs through the same speaker wire, avoiding a separate power run for the lights
• Compact mounting depth suits tight marine speaker pods better than deeper home-audio drivers
• Sold as a matched pair, both speakers come from the same production batch for consistent output

A straightforward upgrade for boats and ATVs with speaker locations already sized for 8-inch drivers.

These speakers handle up to 200W max power with a 100W RMS spec, paired with a frequency response of 85Hz-20kHz through a 1-inch aluminum voice coil for the high end. Sensitivity sits at 90dB, moderate for the category, meaning louder outdoor listening on a boat deck benefits from pairing with an amplifier rather than running directly off a low-power head unit.

The 2-way design splits frequencies across the cone and built-in tweeter for clearer separation between bass and treble than a single-driver speaker offers. Poly carbon cone construction is chosen specifically for its resistance to warping under repeated sun and moisture exposure.

Sized for a standard 6.5-inch OEM cutout at 5.31 inches with a 2.48-inch mounting depth, these speakers are built as drop-in replacements for factory marine or vehicle speaker openings, and the package includes complete wiring and mounting hardware. This standard sizing means most boats, marine watercraft, or vehicles with existing 6.5-inch speaker cutouts can swap these in without modifying the mounting area.

They ship as a pair, both finished in white to match common marine trim and deck colors. No dedicated amplifier is included, so reaching higher volumes outdoors means adding a separate amp to the setup.

Construction combines a poly carbon cone with a butyl rubber surround, materials chosen to resist the warping and cracking that standard paper or foam speaker components suffer under sun and saltwater exposure. The molded ABS plastic basket and grille add further protection against sun damage and impact during outdoor and marine use.

These speakers are built to handle heavy water splashes and general outdoor weather rather than full submersion. The low-profile design keeps the housing compact enough for tight marine mounting locations, such as boat hulls or vehicle door panels, without protruding far past the mounting surface.
