Marine speakers don't just need to sound good — they need to last, too. Sony's XS-MP1621 marine speakers have the auditory bases covered, thanks to responsive polypropylene woofers and tweeters, while durability is ensured with UV-protected components and a water-resistant design.

And, thanks to the sharp styling of the grilles, these 6-1/2" speakers will cut a fine figure in your boat's bulkhead. Don't like white? No problem, the grilles are paintable, so you can customize the look to match your style.

  • white 2-way 6-1/2" marine speakers (pair)

Crutchfield Customer Review (What's this?)

Nice marine speakers. Great sound, affordably priced, easy installation, and good looks. The only thing i would have liked to see included was wiring with the installed ends (20' of speaker wire would be sufficient in most cases). Even though my install was a replacement of existing speakers, i had to modify the terminal ends to fit the Sony's. The small end on the speaker is very small! Other than that, everything works great and i'm happy with the purchase. Ray

Pros: Great looks, great sound, easy install, a perfect replacement for my existing speakers.

Cons: Would like to see some wiring with the terminal ends included in the box.
