Treat your ears to a fuller, richer soundstage! Kenwood has adapted anti-diffraction home speaker technology to their Image Enhancer series car speakers. A smooth, domed ring around the PEI balanced dome tweeter virtually eliminates "bounce back" — reflected sound waves that interfere with direct sound coming from the tweeter itself. The result is wider "sweet spot" dispersion and more accurate mids and highs.

The KFC-1679ie knocks out satisfying bass from a 6-1/2" pearl-mica injection-molded poly woofer. The KFC-1679ie also has mounting tabs for oversized 6-3/4" applications.

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.

Product Research


Image Enhancer: The KFC-1679ie is equipped with Kenwood's patented Image Enhancer surrounding the tweeters. Its smooth rounded surface eliminates most of the reflected sound waves that would interfere with the direct sound waves coming from the tweeters. The end result is a better dispersion pattern, less distortion, and clear high-frequency reproduction. 

Woofers: The woofer cones are silver Pearl Mica Injection-Molded Polypropylene. Uniform pearl mica crystals form an overlapping structure that adds strength and heat resistance to polypropylene; the result is reduced distortion and improved reliability.

Tweeters: The speakers have a 1-3/16" PEI balanced dome 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.

Surrounds: The speakers have a urethane surround.

Grilles: The supplied hard plastic grilles have a unique 3-spoke design with a cutout for the Image Enhancer.

Mounting: The speakers can be mounted in a 6-1/2" opening, or, using the four mounting tabs, the speakers can be mounted in a 6-3/4" opening.

Kenwood KFC-1679ie

Written By Justin, Bethlehem, PA on Wednesday, November 16, 2005

These speakers are just what I wanted. I wanted something with nice mids and highs that wouldn't distort at high volumes. These do the trick. I will be pairing these up a powered Kenwood sub so I'm not too concerned with the bass in these speakers. However, the bass is acceptable at reasonable levels. The higher you go the less detailed the bass sounds. More of just a flat "whap" instead of crisp bass. However, with the right high pass filter settings these speakers sound great at any level. I'm very satisfied with these. The only reason I gave them a 4 was because of the bass, but if you're looking for a configuration like I am, these are perfect.

Also, as a side note, I found that these speakers do fit into the front door of the 2005 Nissan Frontier if you use the 6x9 to 6.5 adapter bracket.

Great sound at a good price!

Crutchfield Customer Review (What's this?)

When I first installed these, I was terribly disappointed. They sounded weaker than the OEM speakers. Well... after much tweaking on the new Kenwood head unit (KDC-X529), I got them to absolutely kick butt! Turns out the X529 defaults to an "OEM" speaker mode, where it 'goes easy' on what it assumes to be OEM speakers. Kick that over to the 6" setting, and the power is unleashed! HUGE improvement over the OEM! The only reason I gave them a 4 vs. a 5 is because you could certainly get more bass out of a component setup, but these are great in the low, and excellend in the mid and high! I highly recommend these!

Very solid speakers for the price

Written By Timothy, Washington ,DC. on Wednesday, April 20, 2005

These are impressive little speakers. Very good bass response when fitted with dynamat. Sounds much better than the stock JBL's that came in my Hyundai.

These won't fit in the standard Tiburon mounting holes, but with a few self tapping screws... problem solved.

Overall, I give these an A-
