JL Audio M6 Marine Subwoofer 10" with Black Luxe Grille (M6-10IB-L-SbSb-4)

M6 Series 10" 4 ohm Marine Subwoofer with Black Luxe Grille (M610IBLSbSb4) (010-03869-00)

Engineered for boat-audio enthusiasts who demand serious bass with marine-grade durability, the JL Audio M6 Series 10″ 4 Ω Marine Subwoofer with Black Luxe Grille (model M610IBLSbSb4) delivers top-tier performance and a sleek, low-profile finish. Whether you’re upgrading your wake-boat system or outfitting a luxury yacht’s audio rig, this subwoofer transforms your sound-stage with clean, deep low end and corrosion-resistant construction.

Key Features & Benefits:

• Delivers 250 W RMS power handling at 4 Ω, giving your system serious bass output while letting your main speakers breathe and play louder with less distortion. 
• Designed for infinite-baffle (free-air) installation, meaning you don’t need a dedicated enclosure—just a large air volume (2 cu ft/56.6 L or more) behind the driver to achieve full performance. 
• Built with a mica-filled injection-molded polypropylene cone and synthetic-rubber surround for rigid performance and low distortion. 
• Features a polymer basket and fine-mesh black Luxe grille that minimally protrudes into your cabin for a clean, integrated look—great for premium vessels.
• Marine-rated hardware: marine-grade brass binding posts, a synthetic fiber spider, polymer basket and stainless steel back plate that resist salt-water exposure and UV abuse. 
• Sensitivity of roughly 86.1 dB at 1 W/1 m, meaning this subwoofer is efficient enough to deliver solid bass without wasting amplifier power. 
• The long-excursion design (one-way Xmax ~0.52″ / 13.2 mm) means the unit moves more air and hits deeper frequencies with authority. 

Why this subwoofer stands out:
Adding this JL Audio M6 Series 10″ subwoofer frees your smaller main speakers from the burden of reproducing deep bass content, allowing them to perform cleaner and louder across their range.

In turn, your entire boat audio system sounds more dynamic at all listening levels. The low-profile mounting bezel combined with the Luxe grille ensures the sub blends into premium marine interiors—so you get not just power but elegance.

Installation & System Setup Tips:

• For free-air (infinite baffle) installations, ensure you have at least 2 cu ft (56.6 L) of available behind the sub for optimal performance. 
• If you choose to mount in a sealed or ported box (though infinite-baffle is preferred for this model), Crutchfield lists recommended net internal volumes: sealed ~2 cu ft and ported ~2.5 cu ft. 
• Use an amplifier rated between 75 W and 250 W RMS into 4 Ω for best performance and reliability. Avoid grossly over-powering the driver beyond rated RMS levels. 
• When installing in a marine environment, use corrosion-resistant mounting hardware, ensure proper sealing of cabinet or panel edges, and use marine-grade wiring (tinned copper, proper gauge) to maintain longevity in salty, humid conditions.
• Set crossover frequency appropriately (e.g., ~80 Hz depending on your system) to send only deep bass to the subwoofer, letting satellites focus on mids/highs for more clarity.

Ideal Applications:

• Premium wake or ski boats where space is limited but serious bass is desired.
• Luxury in-board or cabin vessels where aesthetic integration and rugged marine duty matter.
• Audio systems seeking to upgrade from standard coaxials/minis to a dedicated subwoofer channel without bulky box constraints.

In summary, when you choose the JL Audio M6 Series 10″ 4 Ω Marine Subwoofer with Black Luxe Grill you’re getting a high-performance, marine-duty, low‐profile bass solution that elevates your boat’s audio system both in power and refinement.

From textured wave-crushing bass to crystal-clean mids from your other speakers, this subwoofer completes the soundscape.
