Buyers Guide for the Best 6×8 Speakers for Bass.

All 6×8 speakers for bass are not the same. They differ in design, sensitivity, frequency, sound, and build quality, among other features. Therefore, you need to be sure that all qualities of the speaker suit your needs before making a purchase. Below are five vital factors to consider when buying the best 6×8 speaker for bass.

1. Should You Buy a Component or a Full-Range Speaker?

6×8 speakers fall under these two broad categories. Both component and full-range speakers are excellent choices, depending on your exact needs.

Component speakers have top-notch sound quality. However, they are a bit expensive as compared to full-range speakers. If sound quality is your top priority, these speakers are a perfect choice.

If you are looking for a cheaper version of 6×8 speakers, full-range/ coaxial speakers are the best. Besides being cost-friendly, these speakers are easy to install and also sound good.

After weighing both options and deciding on which type to buy, compare the available options before making the final decision.

2. Build Quality

When shopping for such an essential item, durability should be one of your top priorities. The quality of a speaker’s build materials greatly affects its durability and sound quality. The speaker’s main components are a tweeter, woofer, and the surround/ casing material.

3. Tweeter

In every audio system, the kind of materials used to make tweeters greatly affects its sound quality. If you want a highly refined sound, look for tweeters with soft materials such as silk, textile blends, and poly. Hard materials like ceramic, titanium, metal, and graphite are ideal for people looking for bright and clear sound.

4. Woofer

To achieve low notes from your woofer, you should consider a stiff and lightweight material. Synthetic films such as polypropylene mixed with Mica and woven fabric coated with aluminum or titanium are the ideal materials for a woofer.

Some manufacturers also use Kevlar coated paper on woofers, and it works incredibly well. Water-resistance is another key quality you should look out for in a woofer’s material.

5. Speaker surround

A speaker’s surround facilitates free movement of the cone and is responsible for producing a bold bass. The surround’s material should have the ability to withstand humidity and temperature variations to perform this critical role.

Foam and cloth are the most common materials. Besides being durable, they are affordable. However, the best and most recommended surround material is Butyl rubber. It is a high-quality material and has superior durability.

6. Compatibility and Ease of Installation

One of the most attractive things about 6×8 speakers is that they are compatible with almost all modern vehicle brands. However, it is crucial to understand your car set up and research the appropriate power it can send to the speakers. You can do this through online resources or better still consult with a professional mechanic.

Installation of new 6×8 speakers for bass in your car depends on the type of vehicle. Some cars have complicated wiring systems, which makes installations very tasking, while others are straightforward.

The speakers come with an installation manual, making it easy to do the installation yourself. However, if you are not conversant with car wiring, let a professional mechanic do the installation for you.

7. Frequency Response and Sound Quality

Sound is probably the primary factor that causes people to upgrade or change their car audio systems. But what makes an excellent sound quality?

Sensitivity (dB) is the most significant determinant of a car’s sound quality. The level of sensitivity shows the loudness of the speaker at a given power. It also shows the effectiveness of power conversion from the amplifier to the speaker.

As for the frequency response, the lower the range’ beginning, the deeper the bass. The end of a range shows the highest frequency that that particular speaker can produce.

Most factory car stereos have a low power capability and thus require speakers with over 90dB sensitivity level. However, if your car system is already high-powered, look for speakers with a lower sensitivity level. The higher the sensitivity level, the more efficient the speakers will be.

8. Power Handling Ability

Another term for a speaker’s power handling is Root Mean Square (RMS). Peak power metrics and RMS show the actual amount of power that a speaker can handle. If it exceeds this amount, you risk damaging your speaker.

When shopping for a speaker, always check the maximum RMS and not peak power. A low-powered system needs a low RMS speaker and vice versa.
