R1675 6-3/4

Better components give better detail
The Prime R1675 6-3/4" 3-way speakers sport stiff mica-injected polypropylene woofer cones that deliver strong drums and bass, along with clean reproduction of the midrange frequencies. The Mylar tweeter and supertweeter add the excitement of strong high-frequency response to your music without a trace of harshness. Built-in crossover networks divide the frequencies going to each driver, so all your music plays faithfully. Grilles are included.

  • 6-3/4" 3-way car speakers (pair)
  • mica-injected polypropylene woofer with foam surround
  • 1/2" Mylar balanced dome tweeter
  • piezo supertweeter
  • power range: 2-40 watts RMS (80 watts peak power)

Why replace your factory speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Product Research

Features

Woofer: The Rockford Fosgate Prime R1675 utilizes Mica injected polypropylene cone woofers, cold rolled steel baskets, and foam surrounds.

Dual Tweeters: Each speaker features a 1/2" Mylar balanced dome tweeter and a Mylar Piezo super-tweeter. A semi-dome tweeter has a dome placed inside a cone; balanced dome tweeters are semi-dome tweeters with equal reproduction area given the cone and dome portions of the tweeter. The low distortion Mylar material allows accurate reproduction of high frequencies for an open sound stage.

Mounting: The speaker's mounting ring has multiple mounting holes for various 6-3/4" applications.

Nice speakers

Written By Pete, Bradenton, FL on Wednesday, September 12, 2012

Crutchfield Customer Review (What's this?)

These are 6.75" not 6.5" They sound better than I hoped. I installed in the back doors of my Tundra. Not too bad, better bass response than I thought I'd get, mids and highs are fine. Quality built.

Pros: Great bass and mids, highs are decent

Cons: None

Not enough range for me

Crutchfield Customer Review (What's this?)

Replace the factory speakers with these...Thanks to Crutchfield's awesome support, these will be returned. The range of these speakers is very limited. The highs sound great, but there is no mid's or bass at all. I am ordering some kicker ds60's...hoping these will at least have some midrange sound. Yes, I double checked to make sure everything was hooked up correctly...I have an aftermarket pioneer head unit that is great, but just not with these speakers.

Pros: Crutchfield support

Cons: Only highs..no mids or bass.

Get everything you’ll need to enjoy your new Rockford Fosgate Prime R1675

Reduce ambient road noise and your vehicle's "rattles," for better sound inside your car.
You'll need speaker wire to connect your speakers to your amp.
Keep your speakers clean and dry. They compress to fit behind your speakers.
These speaker connectors are handy if you're running new speaker wire or if your speakers have oversized terminals.
The right tools will help keep your installation simple and clean.
If your stereo doesn't cut the deep bass from your full-range speakers, a set of bass blockers can help prevent distortion and give you cleaner bass too.
