6.5 vs 6x9 speakers comparison

6.5” vs. 6×9” speakers: Which one is worth your money?

The two most commonly used speakers are the 6.5” and 6×9”, producing melodic sound. And, you are wondering what the differences are.

Well, 6.5” and 6×9” differ in several aspects besides size. So, when you’re picking one of the two, you’d want to choose a speaker that matches your current audio system. This guide will provide:

  • Differences between these two speakers
  • Top 6.5” and 6×9” speaker models

So let’s jump right into it!

6.5” vs. 6×9” speaker – Key differences

6.5 vs 6x9 speaker comparison chart
The table illustrates the differences between 6.5” and 6×9” speakers

6.5” models are popular choices among audiophiles looking to upgrade the audio system with aftermarket speakers. They come with power handling capabilities sufficient for producing realistic sound.

6×9” speakers are more futuristic in the sense that they represent an all-in-one speaker solution. Its up-to-date design ensures that the output can reach high frequencies without interruption or distortion. As a result, these speakers offer a premium music experience with deeper bass.

Do 6.5” speakers sound better than 6×9” ones?

Short answer, no it’s worse. For the long answer, it depends.

Even when choosing between the two speaker types, you have to decide whether you want two-way or three-way. These two speaker categories refer to the number of speaker drivers included with the improving frequency range.

For instance, between a high-quality 6×9” and 6.5” three-way, a 6×9” speaker will be your jam. However, a high-quality 6.5” three-way speaker will perform better than a two-way 6×9” speaker. That’s because a two-way 6×9” speaker has a more limited frequency range.

How the speakers are installed also has to be considered. If the 6×9″ speaker is hi-fi, but the installation is not done right, it can sound worse than a low-quality 6.5″ speaker. Hence, you can only compare these two types of speakers when you put them in the same condition about the type, configuration, installation, etc. And, in this way, 6×9” can outweigh the 6.5”.

If you have not yet decided on a speaker for your car, go through the product chart given below to have a smart decision for your audio system.

Where is the best place to mount them?

Typical places for mounting speakers include dash panels, doors, rear deck, or the back of your trunk. The shape comes into play when you are mounting the speakers.

6.5” speakers have a compact design that is ideal for fitting in a classic vehicle. They can fit in any 6.5” or 6.75” opening. The best place to mount them would be on the doors due to their circular shape. That way, you get great surround sound.

As for 6×9” speakers, they are small in size with a modern design. Nevertheless, they do have a larger cone area than 6.5” ones. So when replacing original factory speakers, you may have to fit them after making modifications with a special prying tool. In case they do not, add a speaker adapter or bracket plate. You can mount these speakers on the rear deck for their pleasant outputs.

Speaker design

6.5 vs 6x9 speaker shape comparison
The speaker shape along with its size and material will be a vital role resulting in the sound quality

One of the main differences between the two speaker types is the shape. In the case of speakers, size and shape matter a lot.

A larger surface area means the speaker cone will move more air when in motion. The speaker cone can produce a louder volume, more bass, and overall better performance when it moves more air.

As you know from the chart, 6.5” speakers have a circular shape, and 6×9” ones have an ellipse (oval) shape. Well, 6×9” speakers come with a much larger width, paving the way for bigger cones. So 6×9” can achieve high and midbass frequencies more easily than 6.5” circle speakers.

Which is cheaper?

Since it has a better design and more bass performance, 6×9 speakers tend to be more expensive than 6.5” speakers. In this competition, 6.5” speakers will be the champion with their medium to low prices.

That is why 6.5” speakers are hot among buyers who are looking for something affordable. If you are an audiophile, a 6×9” is the most cost-efficient way to get powerful audio performance.

Who is the winner?

It all comes down to what you prefer in a speaker system.

6.5” speakers are ideal for those who are just looking for an OEM replacement and are not too selective about the harmony. They are an affordable way to get pure sound quality. You may run into some problems with this speaker if you prefer to hear high-frequency sounds. Thus, you will need a subwoofer to help your 6.5” speakers produce the rich melody.

With 6×9” speakers, subwoofers are not needed because they are self-sufficient. You can customize your music to be loud, thereby giving you a better mixture of the frequencies. The quality of the final output is excellent. So, in my view – as a mechanic and an auto-audiophile, 6×9” speakers will be the better choice out of the two.

Top recommended speakers comparison

When buying a new speaker, there are two common types of speakers you should go into – component and coaxial speakers. Coaxial speakers have different drivers, all combined in one structure. On the other hand, component speakers come with drivers that can be installed in several different locations of the car.

Mentioned below is the comparison of the recommended speakers in each category.

6.5” vs. 6×9” coaxial 2-way speaker

Pioneer TS-F1634R and Rockford Fosgate P1692 are excellent choices for 2-way coaxial speakers. Both are designed with a shallow basket for versatile installation and improved sensitivity levels.

Pioneer TS-F1634R has a solid construction with a max power of 250W; yet, its RMS is only at 25W.

The sound enhancement over factory speakers with Rockford Fosgate speakers is much better. Its Vertical Attach Surround Technique (VAST) increases cone area for optimal performance.

Since they are 3-way speakers, Boss Audio CH6530 and CH6930 speakers provide extra mid-bass frequency than 2-way speakers. Both come with a woofer, mid-range, and tweeter. Most specifications are similar, like good durability and cone material.

Although CH6530 offers more bass than most 6.5” speakers, it cannot defeat CH6930 in quality. The surround sound for CH6930 is impeccable, with a better range and clear vibration for hours on end.
