by Ken Nail

When you're the master and commander of your boat, you know how important it is to keep the crew happy.

Pioneer's TS-MR1640 speakers are built specifically for the tough marine environment, so you can count on dependable performance onboard your craft.

The TS-MR1640's 6-1/2" IMPP woofer cones are bonded to weather- and water-resistant rubber surrounds. With a low-end frequency response down to 30 Hz, they're masters at providing full, deep lows. The PEI tweeters will give you bright highs that will command your attention even when fighting against the sound of the waves, wind, and engine noise.

These speakers are designed for your nautical applications, with corrosion-resistant mounting hardware and gold-plated tinsel leads and speaker terminals.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.


UV- and Water-Resistant: These marine speakers feature UV- and water-resistant white grilles, composite speaker baskets, injection-molded polypropylene cones, rubber woofer surrounds, PEI semi-dome tweeters, and stainless steel mounting hardware.

Injection-molded Polypropylene (IMPP) Woofers: Each woofer is constructed from injection-molded polypropylene. This process of cone molding assures a uniform cone thickness for superior linearity and clarity. In addition, the cones are lightweight and rigid for decreased distortion and superior bass response. For a smoother response and increased durability, each woofer uses a rubber surround.

Tweeters: Each speaker uses a 1" PEI semi-dome tweeter. PEI (Poly-Ether Imide) is a polymer that has ideal sound characteristics, making it perfect for use as a tweeter. A PEI semi-dome tweeter produces a wide soundstage for superior imaging.

Pioneer TS-MR1640

Written By Scott Wayne, Essex, MD on Wednesday, June 22, 2011
Crutchfield Customer Review (What's this?)
I bought these speakers to replace Kenwood 6.5 inch speakers on my Grady White. I picked these because of the 91 db sensitivity since I don't have an external amplifier. I believe the Kenwoods were 84 db. These play louder and clearer and can handle a bump in bass. Even my wife noticed the difference. Replacement was easy and took only 15 minutes. They use the same mounting holes as the previous speakers. Very satisfied with this purchase.

These speakers were incredibly clear and undistorted at the loud play levels required on the water. They represent a good buy.

Hi I bought three pairs of tsmr1640 to replace my old tsmr165 The problem is the tsmr165 is a 7" and the 1640 are 6.5" apparently and they won't fit in the hole my tsmr165 had. What can I do? [ Jesse  Mar 17, 2014 ]

  • Thanks guys [ Jesse   Mar 19, 2014 ]
  • I ran into a similar problem, the hole also was too shallow, l used aluminum plate and cut out a ring over sized ,fastened the speaker to the ring and the ring to the surrounding hole and painted the speaker grill to match. It worked for my application. [ JAY   Mar 18, 2014 ]
  • Hey Jesse, The best thing I can tell you is dremel the holes out a little larger with a cutting bit. It really doesn't take that long. Good luck. [ DAVID R   Mar 18, 2014 ]
