Buyer’s Guide: Things to consider when buying 6.5 Speakers


Sensitivity is definitely something you should take into consideration when you’re buying speakers. It’s not about sound quality per se, but is about the volume of your amplifier on your speaker, and how high it needs to be for your speakers to be at their best.

Speaker sensitivity is a measurement of how well a speaker converts amplified power to acoustic energy. So when someone is talking about speaker sensitivity, this is what they’re referring to. Although if you’re reading this article on the best 6 5 car speakers then you probably already know.

Sensitivity is measured by the speaker manufacturer and so different factory speakers will have different sensitivity measurements. So it’s always good to compare similar speakers from different makers, to see if the sensitivity you have on your speaker is the quality you’re looking for.

Depth of Mounting

This is one of the most important things you should consider before buying, as your depth of mounting decides what type of speaker you can buy. Shallow mounting depths and deep mounting depths obviously require different speaker types. So you need to know how much space you have in your car to correctly fit your speaker.

Don’t worry if you don’t have much room either, as shallow mounting speakers are designed for tight spaces and therefore should be just as high quality as regular car speakers.

Another thing to think about when considering mounting depths is speaker enclosure. Speaker enclosure is important for optimal bass response. So if you want a speaker that doesn’t quite fit, then a speaker enclosure takes up that extra space, making sure that your bass response is as high quality as you want.

So this is definitely something to consider when choosing your car speakers.


Frequency Response

Frequency response is normally used to describe the audible frequency range that a loudspeaker can produce.

Audio frequency is measured in hertz (Hz) and the human frequency range is from 20Hz (lower bass notes) to 20 kHz (the highest treble notes). So if you get a speaker, to get one that falls within this range is normally the go to when purchasing.

However, you also want your car speakers to be able to reproduce these frequencies at their optimal level. So the ideal frequency output you’re looking for should be equal to the frequency input of whatever is going into your speaker.

Most factory speakers will have this information, but it’s definitely something you want to look into before purchasing any car speakers, as a great frequency response will produce a great sound.

Additional Features

Even if you’ve researched the above points before purchasing your speakers, you might also want to consider additional features before buying.

  • cross overs – external crossovers are typically used to lessen the amount of distortion a speaker might have by separating frequency inputs. It helps to separate highs and lows. most speakers should come with these, but it’s definitely something to look for before buying just in case they don’t and you’ll have to factor in cross over purchases in the price.
  • RMS (Root mean square) Also known as continuous power rating, is what a speaker consistently uses during it’s performance – most manufacturers will provide you with this information, and is something to consider before purchasing.
  • Design – This might not seem like a big one, especially if your speaker will be in your door out of the way. It also might not seem like to something to think about if you’re only concerned about performance. But for some, design is something they look for different reasons. One, because it might contribute to performance. Some speakers have designs to help improve overall sound quality. But it’s also important to see how it fits into your car with the design, and the overall aesthetic you’re trying to go for with your speakers.


What are the best materials for 6.5 speakers?

It depends on which part of the speaker you’re meaning. There are different elements to speakers such as the cones, voice coils, and dome tweeters; so each element will have a different material that suits it best.

  • Tweeter – Whether it’s dome tweeters or otherwise, the best materials are: – silk or polyurethane, or metal, ceramics, or graphite depending on what kind of sound you want.
  • Woofer – For a woofer, the best material is polypropylene. However, woven fabrics, or metal-coated synthetics can also be used to a similar degree.
  • Surround Materials – The best material is rubber. But cloth and foam surrounds can be used, and these are the less expensive options if you’re worried about price.

How much power do I need for my speakers?

This all depends on your speakers efficiency. The best power your speaker needs also depends on what your music taste is like.

If you’re a fan of more mellow music, such as classical and jazz, then 50 watts would be best for your car.

However, if your music taste is for the louder bass beats, then something around the area of 200-300 watts might be more your speed.

But it’s not just music taste, it’s also down to how loud you want your music to go, so whether you’re the resident parking lot DJ, or are known to have impromptu festivals from your car, a higher wattage might be the way to go.

What are the best 6.5 speakers for bass?

From our list, due to research and reviews, and the materials these speakers are made out of, there are several speaker manufacturers that we would suggest are the best speakers for bass:

  • Rockford Fosgate
  • Pioneer TS
  • Boss Audio
  • Kicker
  • JBL

There are other speaker manufacturers out there, but these are the ones that we think give your bass some bounce. Just take a look at our ones on the list and see what you think for yourself!

Are 6.5 and 6.75 speakers the same?

There is no real difference between 6 5 inch speakers and 6 75 inch speakers when it comes to elements such as high frequency rates, RMS, and sensitivity rating etc.

The difference between the two is just the small difference in size, and even if you accidentally buy 6 5 inch speakers when you needed 6 75 inch speakers, you can always purchase a speaker enclosure to close the gap, and make sure your speakers are nice and snug, making sure you still get that optimal sound.
