You jump in your ride and turn on your favorite song — you're straining to hear the snare drum, but it's still just barely audible. And that dull, fuzzy-sounding bass guitar is just about breaking your heart. Pioneer TS-A Series speakers bring your music back into focus with precise, superior reproduction of instruments and vocals, so all those details you love will really pop.

Pioneer's TS-A1684R 4-way speakers feature a 6-1/2" woofer with a stiff Aramid-reinforced polypropylene cone that ensures clarity in your music's bass and percussion. The highly elastic polymer surround helps keep cone movement under control, for smooth, tight bass. A 3/4" dome fills in all the midrange details for lush vocals and crisp instruments.

A soft dome tweeter and supertweeter deliver warm, dimensional treble, so you'll hear all the overtones that give your music ambiance. The built-in crossover ensures that the right frequencies go to the tweeters, midrange, and woofer, so your music sounds natural, just as the artist intended.

Product Highlights:

  • 6-1/2"/6-3/4" 4-way car speakers (pair)
  • mica-injected polypropylene woofer with elastic polymer surround
  • 3/4" dome midrange
  • 3/8" and 7/16" Mylar balanced dome tweeter and supertweeter
  • power range: 2-50 watts RMS (350 watts peak power)
  • frequency response: 33-27,000 Hz
  • sensitivity: 91 dB
  • top-mount depth: 2-3/16"
  • grilles included
  • warranty: 1 year
  • Our 60-day money-back guarantee

Why replace your car's original 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.

Features

Woofers: Each speaker features an IMPP (Injection Molded Polypropylene) cone woofer interlaced with carbon graphite and long aramid fibers and a 12-ounce strontium ferrite magnet. This IMPP cone design provides the strength and rigidity that powerful bass requires. The high-density, compressed internal architecture is resilient and transfers sound very quickly. The result is full-bodied, rich sound.

Surrounds: For durability and a smooth response, each woofer uses an elastic polymer surround.

Midranges: Each speaker has a 3/4" polyester fiber dome midrange for accurate response with low distortion. The midranges have 0.2 ounce neodymium magnets.

Tweeters: Each speaker uses a 7/16" dome tweeter and a 3/8" dome super tweeter made from PET (Polyethylene Terephthalate) film for crisp, clear highs.

Mounting: The speakers can be mounted in standard 6-1/2" openings, 4-hole 6-1/2" openings, or 6-3/4" openings.

Love these speakers

Written By Detron, Kenosha WI on Thursday, October 04, 2012

Crutchfield Customer Review (What's this?)

I love my Pioneer TS-A1684R speakers, I put for of them into my 2008 Kia sportage, and all of my friends love the sound. One of my friends no longer likes music in his car, because he realizes he is getting a low end factory system sound, he did not know this until he heard these speakers.

I love the super tweets that are built in, some of the highs sound so clear, and even old favorites have new life with these speakers. Pink Floyds money sounds different, just because of some of the highs that were not present on my factory speakers.

Pros: descent bass, amazing mids and highs

Cons: none

TS-A1684R Sound Fantastic in 2008 Impala

Crutchfield Customer Review (What's this?)

Everything needed for easy and quick install included. Crutchfield includes excellent instructions taking you step by step through the process. These Pioneers are a huge improvement over stock speakers. I paired them with Pioneer TS-A6964R's which are in the rear deck giving me a rock concert every day to work! Now I'll replace the tweeters to complete the job.

Pros: Ease of installation and great result.

just as advertised

Crutchfield Customer Review (What's this?)

speakers work exactly as imagined. Replaced stock front and rear speakers and deck at the same time. Had to drill new mounting holes since stock Camry housing was prefab to the old speaker. Speakers work fine, perfect entry level speakers to replace stock. Note: Could not use wire harnesses provided. Connector didn't plug into existing, plus the wire was too short, I had to cut and resplice harness.

Great for the money

Crutchfield Customer Review (What's this?)

I bought these speakers to put in my '98 Camry with the new Kenwood KDC-248U receiver I installed the previous week. Compared to the factory speakers, these sound great and didn't empty my bank account. I have the bass turned down on the receiver because they do get a little distorted at a high volume on songs with a lot of bass but not so much so that the bass is completely missing from the song. I am very happy with these speakers and would recommend them to anyone looking to swap out factory speakers without breaking the bank.

A Trade Off

Written By Suspence23, Kenmore, WA on Thursday, August 11, 2011

So first and foremost, these speakers work great, no problem with them at all. The problem lies in the car. I am putting this one here to warn people of the problems. I have a 2000 Subaru Impreza Outback Sport. These DO NOT fit in the front doors like crutchfield says. 1. The speaker baffle is too small for the speaker, and has 3 holes instead of 4 for the speaker to drill into. 2. I went to 3 professionals and asked what to do about the speaker baffle problem, and they all told me, is what the do is just drill it into the door itself, and thats it. ONE PROBLEM! If you were to do that with these speakers, when you go to slide the window down it will hit the back of the speaker!!! Don't buy these for this model car unless if you want to lose to use of your windows. That is all. Great speakers though!

[Editor's Note: Our Installation Details state "Cut out the back of the plastic factory cup or mounting bracket to provide enough depth for your new speakers."]

They sound great! High to low and everywhere in between. A loose fit for the
front doors of my '05 Cobalt.
