Purpose-built for real-world marine duty, JL Audio's M3-Series subwoofer drivers are designed to deliver outstanding bass performance that will transform your boat’s audio system.
With appropriate system setup, the addition of a subwoofer allows your smaller main speakers to be free of the burden of reproducing low frequencies. This allows your whole system to play louder and to sound cleaner at all listening levels.
Targeted towards moderate powered applications, the 10-inch, M3-10IB is designed to operate without a dedicated enclosure and features long excursion capabilities with a rugged suspension system. For best audio performance, the M3-10IB is best used with amplifier power in the 50-175 W range and is optimized to operate with a large volume of air behind it (at least 2 cu. ft. / 56.6 l).
All JL Audio marine speakers are saltwater-rated, utilizing corrosion and UV resistant materials throughout to deliver years of listening enjoyment.
