Top Best  Best Pioneer 4 Inch Speakers on The Market

#1- Editor’s Choice- Pioneer TSG1045R 4-Inch 210W 2-Way Car Speakers

When it comes down to it, most people are looking for replacements for stock speakers when they’re trying to find a 4 inch speaker.

We find ourselves pretty much in love with these. With a 210W peak and 30W RMS, you can rest assured that these provide plenty of sound and they’re 2-way which means even more clarity than you’d already be receiving from 4” speakers.

They’re easy to install as well, and newbie-friendliness plus awesome sound quality makes them our pick for the largest number of people looking for a great upgrade.

They’re loud, clear, and make a clear and perfect upgrade for those stock speakers which just aren’t cutting it anymore. If you look no farther, you can pick these up and rest assured that you’re in good hands.

What We Like

  • Awesome sound quality
  • 2-way speakers
  • 210W peak, 30W RMS
  • High build-quality

What We Didn’t Like

  • No grill turns off some users
  • Not exceptionally durable


Our second favorite is a little bit higher in cost and part of the Pioneer G-series. These coaxial speakers are designed to sound like component speakers while eliminating the extra installation time.

They’re a little bit less powerful than our first picks, coming with a 190W with 30W nominal but the main thing that pushed them down from being our primary pick is that they’re only a single speaker.

That said, they still offer that Pioneer quality that you know and love and most people will find them to be a perfect upgrade over their stock speakers.

If you’re not quite in the “low budget” range but don’t want to spend top dollar just yet, then these speakers might be exactly what you’re looking for.

We can’t recommend them for even budding audiophiles, but for someone who wants a solid upgrade… they’re top notch.

What We Like

  • 190W peak, 30W RMS
  • High-build quality
  • Excellent, attractive grill covers
  • Awesome price

What We Didn’t Like

  • 1-way
  • A little bit weak

Our favorite budget option of the easily available 4 inch speakers from Pioneer, these tiny cones still pack a punch when it comes down to it with 150W peak and 20W continuous. That may not sound like much, but it’s getting up there when it comes to speakers of this size.

They’re also super cheap, no matter how you look at things. Most people can afford to use these to replace stock speakers without any difficulty and that’s a win for everyone.

These speakers serve pretty well through mid and high ranges, but they’re a bit lacking in bass. That’s normal for this size of speaker, but if you’re willing to spend a little bit more you can handle the lower end of the soundscape a bit more deftly.

That said, we definitely wouldn’t hesitate to recommend adding a pair of these to your vehicle if you want to save a couple of bucks from our first pick.

What We Like

  • 150W peak, 20W RMS
  • High build-quality
  • Easy to install
  • 2-way speakers

What We Didn’t Like

  • Really light on bass
  • Distorts at higher volume pretty easily

If you’re willing to spend about double what you would on the G-series of Pioneer speakers, you can pick up the A series which are some serious component speakers.

While the power rating isn’t superior on these, coming in at 150W peak and 20W nominal, you’ll be able to enjoy these 3-way speakers through a wide range of different sounds.

They’ve got a 90dB sensitivity, allowing you to fine tune the volume and get things going amazingly well for a 4 inch speaker which don’t have much a reputation for being lound.

They function as both a shockingly good mid-range and a tweeter, allowing you to get an impressive amount of usage right from the get-go.

The A-series is also infamously well-built, for most people they’re going to last for the entire time you’ll have the vehicle as well.

If you’ll settle for only the best, then these are exactly the speakers you’re looking for. Just remember that you have to pay a premium to ensure you get the best.

What We Like

  • Crystal clear sound quality
  • Functions as mid-range and a tweeter
  • Impressive 90dB sensitivity
  • Easy to install

What We Didn’t Like

  • Treble can get lost in mid-range at low volumes
  • Lacking bass

It’s not suitable for everyone, but this part of the Pro Series from Pioneer is perfect for those who are looking for a great tweeter.

The entire thing is made of materials which you simply won’t be able to get with lesser products, including a titanium diaphragm which is sure to last basically forever.

This is a top of the line tweeter, topping out at an amazing 500W.

Of course, you have to keep in mind this a specialized component which lacks the mid-range of most 4 inch speakers as well. It can be an integral part of a high-end setup, but for most people it’s not going to be the best option unless you’ve already got a serious system.

The fact of the matter is… the wattage is too high if you’re not running a fully upgraded setup.

If you are, however, consider buying a pair of these tweeters to really push your treble’s sound quality to a realm that you didn’t even know was possible.

What We Like

  • Super high-end tweeter
  • 500W peak power
  • Incredible build-quality
  • Easy to install

What We Didn’t Like

  • Expensive
  • Only one comes with the purchase, buy two if you want a pair

Why Pioneer?

With so many different brands of speakers kicking around, it can be hard to really point to one specific manufacturer as the absolute best.

Everyone does things just a little bit differently, after all, and when you get past a certain point it’s mostly personal taste you’re going to be discussing.

We feel Pioneer does one thing best: they offer the perfect balance between cost and performance, making them an excellent choice for everyone from newbies to pros.

While there are definitely audiophiles who might turn their nose down at them, most people will find themselves well-served by this company and we really like to feature their products no matter what size or series.

We feel strongly about providing the best value to the uneducated buyer: so we recommend Pioneer.

Choosing Your 4 Inch Speakers

4 inch speakers are best for the higher ranges, there are even dedicated tweeters made in this size that only handle the high end range of sounds.

Upgrading 4 inchers isn’t going to give you a whole lot of bass, is what we’re getting at.

What you can get is crystal clear highs to accompany the whole thing. If you’re the type who focuses on the whole soundscape instead of just the lows, then you’ll be in good hands with the right Pioneer 4 inch speaker.

Of course, picking them out can be a bit difficult if you don’t know much about technical specifications, so let’s cover the basics and help you make an educated choice.

1- Power Handling

This is probably the easiest metric to understand for most people.

Fortunately, it’s also one of the most important as well.

When you’re looking for the amount of power that a speaker can handle the most often advertised wattage rating you’re going to see is the peak. This is all well and good, but it actually doesn’t give you quite as good of an overview of things as you’d probably think.

Instead you need to look for the RMS, or continuous, wattage which a speaker puts out. This will let you know what type of power you can supply to a speaker without distortion.

We’ve all had the experience where we turn our speakers up and they sound terrible at one point or another, the higher the continuous wattage rating you have… the higher of a volume you’ll experience distortion at.

2- Material

Differing series of Pioneer speakers have different materials used for them.

For tweeters and high-range speakers like 4 inchers, there’s not quite as much difference as you’ll find when it comes to woofers and large speaker cones.

Instead, you’re going to want to look for the build-quality of the speakers. The tighter the build, the better they’ll sound and the longer they’ll last.

The better ones aren’t going to be built out of paper, but regardless of the material you can actually achieve pretty good sound as long as you’re careful with your selection.


3- Sub-speakers

When you see a speaker labeled as “2-way” or “3-way” it means they’re an all-range speaker.

The higher the amount of subspeakers, the better off you’ll be if you’re using your 4 inch speakers for full-range.

On the other hand, tweeters make an excellent accompaniment to 6.5, 6x9 ( Best Pioneer 6x9 Car Speakers, Best Pioneer 6.5 Car Speakers)or other full range speaker types and can let you get a high range out of your sound system while tuning the others to a more appropriate range.

That’s especially important if you’re using coaxial speakers for the rest of your speakers.

Speaking of which…

4- Coaxial vs. Component

Coaxial speakers are easier to install and use for most people, while component speakers are a little bit more complicated but also… well, they sound better.

There’s two reasons for that: the first is the fact that coaxial speakers tend to be focused on audiophiles so they’re inevitably made of better materials than coaxial speakers which are within the same wattage range.

The second is the fact that you can tune component speakers to a wider range thanks to the fact that they have multiple drivers. With one for each subspeaker, you can set each individual component to your liking.

The choice between these two will basically boil down to how much work you’re planning on doing.

If you just want a quick replacement: go with a coaxial speaker. If you’re looking to get the absolute best sound quality then you’ll want to go with component speakers.

5- Budget

Your budget is always going to be a factor, which is why we always offer a cheaper speaker for those who are just looking to get started with a minimal amount of sunk cost.

Chances are that any Pioneer speaker your replace the stock ones with is going to be a whole lot better than what you’re used to.

To get superior sound, however, you’re always going to end up spending a little bit more money. It’s not a bad idea to invest a good amount from the start, however, especially if you’re planning on keeping the car for a while since higher-quality speakers also tend to last a lot longer.


We hope that we’ve helped you find the best Pioneer 4 inch speakers for you. If you’re still undecided, we strongly recommend our editor’s pick of Pioneer TSG1045R 4-Inch 210W 2-Way Car Speakers for those who still aren’t sure what they need.

There’s definitely something here for everyone, however, whether you need a budget pick or want to drop in a pair of amazingly well constructed tweeters. What are you waiting for? Fantastic sound quality can be yours at a great price.
