• M6 8-inch marine subwoofer for infinite baffle use (200 W, 4 Ω) - Gloss white trim ring, glossy white classic grille
• With the right system design, adding a subwoofer can free your smaller main speakers from the burden of reproducing low frequencies, allowing your entire system to play louder and sound cleaner at all listening levels.
• Designed and built specifically for marine use, the M6 ​​infinite baffle woofers are designed to operate without the need for a special enclosure. The long excursion capability and robust suspension systems help produce a deep, powerful bass response that will transform your boat's audio system.
