Bass Focus - If you listen to a lot of music that is particularly bass heavy, such as trap, EDM, or house, you will either want a 6 x 8 speaker model for which you can dedicate one speaker specifically to bass, or you can purchase a subwoofer and leave the high- and mid-end frequencies to your 6 x 8 speakers.
6x8 Speakers Buying Guide
Whilst you have probably noticed that many of the arrays available don’t differ too heavily from one another in terms of their design and functionality, though some exceed the capabilities of others.
In this guide, we aim to give you a good general overview of what to be aware of before you buy.
What to look for in 6x8 speakers?
When shopping with a dictated dimension, the space available is limited between each product, however, there are some manufacturers who implement clever design refinements to ensure their speakers will take advantage of the space more effectively, work more efficiently, respond more accurately, and are better balanced in the crossover.
This can be seen in the PlusOne cone technology model and the Vertical Attach Sound Technique employed in some of those we have presented in today's reviews.
One thing to consider is just how you like your bass, as that can be the most difficult thing to do justice in a smaller space. If you listen to bass heavy genres it is probably wiser to opt for a 2.1 setup in your car with a speaker dedicated to handling the low-end frequencies and freeing up your left and rights to deal with the mids and highs.
Speakers usually function far better in an arranged set-up. If you listen to particularly low-frequency genres or you like to feel the air move and aren’t averse to growling distortion you may even want to take this one step further and invest in the subwoofer.
Of course, your set-up is largely dictated by your speaker amplification powers. First you need to know how many channels you have available and at what power and impedance each is capable of working at. Some amplifiers have versatile channels which give the user a little more wiggle room to play with.
If you don’t know your amplifiers specs, it might be wiser to seek a professional to upgrade or replace your speakers. If you want to go ahead on your own we suggest replacing each speaker with a model that matches the specs of the one removed.
Replacing a speaker isn’t too difficult a job and if you are willing to do a bit of digging you can typically find an instructional video or two online with details, you may even find a video specific to the model you are looking to install on your car itself. Though it isn’t a huge job if you have a little know-how, it is important to remember that it is recommended to let a professional do the job.
If you don’t have too much experience you are probably best off opting for a coaxial style car speaker as they are already paired to handle the highs and lows together in unison, but some cars call for component speakers it is really dependent on your original set-up.
Component speakers allow for more control over your treble frequency placement often opting for separate tweeters (high-frequency response speakers) on the dashboard itself closer to the driver. The majority of tweeters these days can pivot which makes the sound more accurately directional and allows you to control where the audio produced is directed. You might want to head on over to our 10 Best Component Speakers article for inspiration and information in its detailed buyer's guide.
The high frequencies usually hold the details of the audio, if they aren’t catered to well, then the audio loses a lot of clarity and definition and it becomes difficult or muffled to hear. This is especially true for spoken word so if you listen to radio programming or use Bluetooth for hands-free calling in your car it is essential to have a good mid-range and high response to get the necessary definition and avoid confusion.
For full-range sound you need at least a 2-way classified set to better cover the highs and lows typically this will be a woofer-tweeter pairing with the woofer ideally taking the mid-range in a 2.1 system, however, the audiophiles out there will probably be better of seeking out a 3-way classified set to better cater to their tastes. A 3-way class set supported by a dedicated sub cover a far broader spectrum and provide richer, spacial audio.
The quality of construction and engineering is most important as well as the materials used within the components. Speaker cones need to both rigid enough to withstand the motion but flexible enough to sensitively pick up the signals processed and respond. Typically they are of a stiffened paper or pulp composition, sometimes this is more synthetic utilizing polypropylene for example as you will have seen in some of our top ten selections.
The magnets need to be good grade and oversized voice coils react better within the magnetic fields. The tweeters should be dome style and if there are pivot mounted they will direct the sound better providing better definition.
Generally speaking, the majority of dedicated car speakers on the market typically have a little more to offer than your stock speakers and with a competitive market full of manufacturers trying to undercut the next we are seeing some surprisingly good products which cost very little to purchase.
There has never been a better to replace your car speakers than in the current economic climate, even the models sitting in the lower priced regions serve as a great upgrade.
We have highlighted a fair few options which each makes for strong candidates and our buyer's guide will hopefully have helped to clue you in a little more before you commit to your new speakers.
