Sony 6-1/2" Dual-Cone Marine Speakers (White) - XS-MP1611

- Sony’s dual‑cone design blends a polypropylene woofer and dome tweeter, delivering wide 45–20,000 Hz frequency response with 65 W RMS (140 W peak) per speaker—ideal for clear mids and highs with decent bass 
- Certified IPX5 and rated for UV/saltwater exposure (ASTM standards), making it a solid choice for outdoor or marine environments
- Compact 2.1″ mounting depth and standard cutout size (4‑15/16″) allow easy retrofit into boats, ATVs, or RVs with existing speaker openings 
- Customer reviews praise value and durability, though some note cone wear after ~2–3 years in harsh marine conditions—better suited for freshwater or covered deck installations
