Edge-driven tweeter design

Infinity employs an edge-driven design in their soft dome tweeters for a smoother, more open response and minimal distortion at high volume. Prepare for a more clearly defined soundstage as the details in your music come alive. 

Famous Plus One+ technology

This Primus polypropylene woofer delivers solid, punchy bass, thanks to Infinity's proprietary Plus One+ woofer design. Infinity extends the cone right up to the edge of the basket, giving you lots of surface area — and a bigger cone means more bass when your music needs it.

Make the most of your power

Infinity's special "true 4-ohm architecture" uses a low-impedance voice coil to safely draw extra power out of your factory radio, aftermarket stereo, or an external amplifier, so you'll get a stronger clearer sound.

Grilles are not included; the factory grilles should be suitable for most applications.

Nice Upgrade

Verified employee purchase (What's this?)

I purchased these speakers to replace the rear speakers in my Bugeye WRX. I was able to fit them with spacers. They're much better than stock speakers in terms of clarity. I'm running them from my Apline iLX-207, but plan to run them from an amplifier in the near future.

Pros: Improvement over stock speakers.

Cons:

Good Speakers

Adam from Cleveland, OH on 12/24/2018

Verified employee purchase (What's this?)

I'm very happy with these speakers. So much of the sound quality from a speaker depends on what's driving them, but I have a quality receiver/ amp and these speakers seem well built. After playing with the EQ for a short while these things were sounding like a dream. They're 5.25" speakers, so don't expect them to blow you away, but once they're dialed in you'll be happy.

Pros: quality sound for price solid construction expected longevity

Cons:

They are decent speakers but the seriously lack on bass. I'm going to return them for something different as I'm not very happy. The sound is pretty good though I will say.

How do they do it?

Andrew from Corvallis, OR on 9/7/2018

1995 Ford Windstar

Verified customer (What's this?)
Verified employee purchase (What's this?)

How the heck can such good sound come out of 5-1/4" speakers? I'm rating these within the 6" range. They do need a subwoofer for the full range but I am blown away that they sound so good, much more than I would expect. Excellent highs and midrange, and great, clean bass (down to mid-bass). No mud at all with the mid-range JVC receiver that I also bought from Crutchfield.

Pros: Really great sound down to mid-bass.

Cons: They need a subwoofer, but what do you expect?

They were a hug upgrade over my factory speakers. Even though the amp in my stereo can't fully power them, they sound great and will sound even better I'm sure with the proper amp.

2007 Subaru Impreza 2.5i

Verified employee purchase (What's this?)

Other customers have said in their reviews that the bass on these speakers is missing? That's not at all true, these are two way speakers, not subwoofers. For a two way speaker, the bass is no doubt sufficient, and even a little more than I expected. Use a crossover on these to cut out the low frequencies and use them as intended, and they sound amazing. Big sound from a relatively small speaker. To put into perspective, these sound significantly better than my 6.5" pioneer two ways of same rms wattage. Awesome speaker.

Pros: Big sound from relatively small sized speaker

Cons: Tweeter protrudes out of speaker, so mag run into a scenario in which the door panel does not sit flush as I did. Ended up having to cut a hole in the door panel with a router and use a speaker grill. Would be nice if the speakers game with grills.

These speakers are a very good choice to replace factory speakers. I only wish they made a 2 ohm version to match the factory stereo.

Pros: Big improvement in sound quality over facotry speakers

Cons: A 2 ohm version is not available.

These speakers are great. They put out power and have a great sound. Such an upgrade from stock. Every speaker in my car is going to be Infinity.

Product Research

Features

Plus One Woofer Cones: The Plus One speaker cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and an increase in efficiency.

Voice Coil: The Primus Series speakers feature 2.7Ω voice coils to compensate for the high in-line resistance of small gauge factory wiring and extract every watt from the factory receiver, increasing overall system output and efficiency (relative to 4-ohm speakers). The speakers also benefit from increased power when you upgrade the wire and add aftermarket amplifiers capable of powering a lower impedance load.
