Our take on the Sony XS-MP1621

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.

Style and sound for your boat

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.

Crutchfield Customer Review (What's this?)

The first pair failed after 2 years. Cones were dry rotted and cracked. I am concerned that they are not truly Marine quality.

Pros: Good sound and price

Cons: Not durable

It took only minutes to install each speaker. More efficient and richer sounding than the factory installed Sony speakers being replaced.

Crutchfield Customer Review (What's this?)

Sounds great, looks great , easy to install. Has a cardboard template on back of box.

Pros: None

Cons: Good quality

don't hold up very well

t e from trent woods nc on 3/2/2016

really good sound for price but they only last about a year and a half. in fairness, all 4 on the boat are fully exposed, all year round. i am on my 3 set in 5 years. will be spending a little more money this year and going with truly "marine" speakers

Pros: good sound for the price

Cons: just can't handle constant exposure

Speakers were easy to replace and sound great. Hopefully they will hold up well in marine environment

Pros: Easy to replace. Sound great

Cons: None

Nice speakers

RaySea from New York on 8/9/2012

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.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

Exact replacement for the speakers i had before - fit like a glove. [ Eric  Jul 05, 2017 ]
We installed these speakers on our Pontoon Boat four years ago with a Kenwood Marine Radio purchased from Crutchfield and have been extremely pleased with the performance, reliability, and durability of the system ever since. It was time to add two more speakers to finally realize the full sound of a four speaker system on board our boat. [ Duane  Mar 18, 2017 ]
Existing speakers were Sony and wattage matched up with receiver [ Ben  Oct 10, 2016 ]
They fit existing cut out, and Sony is a reputable brand that offers high value for the dollar. I have owned Sony products before. [ William Terry  Jul 16, 2016 ]
price [ bryan  Jul 07, 2016 ]
I chose this because it will work well without an amp, for the frequency response response range which is amazing for the class (no subwoofer required), and for the relatively compact size. Although some reviews worry about full sun exposure in Florida, this wont apply to my install. [ james  Jun 29, 2016 ]
good quality and great price. [ S  Jun 07, 2016 ]
accidently broke one of my other speakers so have to buy one. [ Gregory M.  May 12, 2016 ]
Top of the ratings with best price and warranty. [ Brian  Apr 15, 2016 ]
