Buyer’s Guide 

Should I check the audio quality across the full frequency range?

We suggest that you check the audio quality across the frequency range as it can tell you if you are using too much bass, treble, high or mid-range. Once you find out the problem, you can simply adjust that part according to your needs and you will get a good sound quality. Otherwise, if this process goes unchecked, the overall quality of the audio can sound unprofessional. That is why we always recommend that you check the audio quality across the full range of frequency. 

How much impact does sound clarity have on bass production?

If you boost the sound clarity, the bass will sound better and have a higher quality. With that being said, if you boost the sound clarity too much, the bass will not sound as good and the overall sound will be muffled and distorted resulting in a bad bass production. 

What’s the best sensitivity range for 6×9 speakers for bass?

Usually, speakers have around 87-88 decibels of sensitivity which is great. To get the best results, a speaker that has over 90 decibels sensitivity is considered to be phenomenal. You will get good bass and overall full-range of sound on that speaker. 

Do tweeters really matter if I’m looking for 6×9 speakers for bass?

Tweeters are a must-have in any speakers as they ensure that the high frequencies are loud enough for you to hear properly. Not only high-range, but tweeters also help with mid-range sounds and make the quality of it much better. Normally all the speakers already have a tweeter inside them so you do not have to worry about this factor.

How can I tell which woofer materials deliver the best bass?

There are mainly three materials, paper, plastic, and metal. The paper material is light and gives a great quality of sound but can be destroyed in high temperatures. The plastic material is well versed and gives a great sound quality regardless of the temperature. The metal material is good but it dampens the sound quality and you might not think the sound is loud enough. We suggest that you go for the plastic material as it gives you the best results as compared to the other two.  

How do surrounding materials impact bass?

The surrounding materials of your room or car can have an impact on bass, whether it’s a small impact or a large one. Once the sound leaves the speakers, they reflect off of the floor, ceiling and car seats just to name a few things. Some of these reflections can distort the sound and make the quality of it bad. Usually, in a car, you do not have to worry about this as the speakers are near your ears.

Frequently Asked Questions (FAQs)

Do JBL GTO939 come with grills?

Yes, the JBL GTO939 comes with a grill that is attached to the front with a couple of screws. The shape of the grill is dome-shaped and it compliments the overall design of these speakers and makes them good to look at. 

Are the woofer and tweeter of Infinity Kappa 693.11 waterproof?

One thing that most users complain about this product is that they are advertised as waterproof but in reality, they do not work if excess amounts of water get poured on them. These speakers are only water-resistant. Which means that they can withstand a little amount of water. 

Does the grill on Polk Audio DB691 come off?

The grill on top of these speakers can be easily removed. On top of that, they are waterproof speakers which you can even use in boats if you want to. Although the grills are separate, they screw in with the speaker. You can remove it by unscrewing it and pulling it off. 

What size amp would be recommended for Jl Audio C2-690tx?

The JI Audio C2 is a great speaker that gives you a clear and crisp sound. On top of that, they have a loud sound with exceptional bass. If you are using an amp with these speakers, we recommend that you use an amp ranging from 50 RMS to 75 RMS per speaker.

Can you surface mount Kenwood KFC-6965S?

You can surface mount these speakers if you want to but most of the time you will not have to do so. Some cars like the 2003 Cavalier do not require you to surface mount the speakers which means that you do not have to do it.  

Do 6×9 speakers require an amplifier?

Normally you will not need to use an amplifier with your 6×9 speakers. This is due to the fact that these speakers are compatible with a lot of modern stereo players. However, if you want to use them with the traditional stereo players, then you will need an amplifier.  

Can 6X9 speakers provide powerful bass?

One great thing about the 6×9 speakers is that they are exceptional at giving powerful bass. Some of these speakers might have an average sounding bass but some of the top-rated speakers such as the Rockford R169X2 have phenomenal bass.

How do I install 6×9 speakers in my rear deck?

To do so, you must first remove the grilles and detach your previous speakers. Once you have done that, attach the new speakers and wire them the same way you would wire the door speakers. This might seem complicated, but it is a simple thing to do. 

Do I need a subwoofer for 6×9 speakers?

This is a common misconception but in reality, you do not need to get a subwoofer for your 6×9 speakers. This is due to the fact that these speakers have a 3-way sound design which means that the subwoofer is already included in the speaker itself. 

How much battery power do 6×9 speakers use?

This is something that depends on the battery of the car that you are using. Some batteries can run for ages when using the 6×9 speakers while some will shut down quickly. Normally, the 6×9 speakers require around 480 watts per hour. 

Wrapping Things Up 

6×9 speakers are a great option for replacing factory speakers, especially when the bass is considered.

Our best choice has to be the Rockford R169X2 6 x 9 coaxial speaker, as it delivers superb full-range performance.
