When it goes about the quality car music, the first thing to do is install the best 6×9 speakers. Their performance usually differs greatly from the regular stock speakers, while the price isn’t high.
The market offers plenty of alternatives varying in design, build and sound quality, mounting options, etc. Here’s a shortlist of parameters to consider when purchasing the speakers for your car:
- Drivers. The basic models represent a single driver transmitting the whole frequency range. Still, there are models having more drivers (even 4-driver ones, with super-tweeter) and ensuring better handling of extreme frequencies. Still, the differentiation of drivers usually means higher power requirements and the need for a good crossover.
- Power and amplifier requirements. The additional car speaker systems usually require little power. However, the better the driver build, sensitivity, and output, the more power is required. Some speakers even require an external amplifier to produce all the juice they possess. At the same time, hooking up an amplifier means more twiddling with the installation and additional costs involved.
- Mounting method. While all models are of the same size, they differ in the actual construction and method of mounting. Some can have propping or too recessed grills, others feature the holes that don’t match with the car design, etc. Consider the mounting method and tools required before buying the particular speaker model.

What Makes Speakers Sound Well?
When listening to different models of speakers, one might notice there’s a difference in their output. While the sound quality estimation is rather subjective, there are basic parameters widely acknowledged as “good sound”. Grouped together, they are based on sound fidelity or authenticity.
The first parameter to consider is the “working” range or the speaker or its frequency response. This rate shows the spectrum of frequencies the speaker can reproduce faithfully, with high fidelity to the source. Usually, the frequency range provided by the speakers’ manufacturer falls within the spectrum audible by the human ear (16Hz – 20 kHz). The frequencies exceeding these limits aren’t audible; yet, the clear reproduction of 22 kHz or 14Hz frequencies will result in more balanced sound transmission, with more detail, transparency, and dynamics.
The frequency range can be separated into sub-ranges having their own designation. The sub-bass frequencies reign on 20 – 60Hz, the bass goes at 60 – 250Hz, lower mids start with 250Hz and end up somewhere near 500Hz, the midrange falls within 500Hz – 2 kHz spectrum, upper mids reach 4KHz, and all of the above is usually marked as “highs”.
The majority of modern speakers provides a wide range of frequencies handled. However, their output differs considerably. The range alone doesn’t stand for the good sound, but the character of the response matters as well. Usually, the more enhanced speakers’ models provide more even response pattern and “catch” the vast frequency range. However, one model can surpass another at some level of frequencies (e.g. lows or mids). This advantage is both discerned by the ear and can be seen on the frequency chart. The flatter, closer to the central line is the signal, the more accurate the frequency response is.
Driver cones materials
Driver cones in speakers serve to push the sound wave and disperse it. While the task seems simple, differently composed cones don’t do it in the same way.
The cone material defines how rigid the cone is, how fast it pushes the sound, and how much distortion is added to the wave. Distortion could be caused both by cone vibration and external factors.
The more the cone’s surface deforms, the more distortion it adds to the sound. However, the hard metal or steel brings the metallic echo and aftertaste, which is unfavorable for the sound. Another reservation concerns the cone movement. It moves back and forth to push the wave; so, it should be lightweight enough to be pushed by the small electric impulse. So, today manufacturers test various materials and composites attempting to find the balance between cone rigidity and natural sound. At the same time, it should be taken into account that particular frequencies are handled better by more or less rigid materials. The most popular cone materials are the following:
- Polypropylene has good rigidity and uniformity but less dynamic than paper analogs. Another big advantage of the PET cones is their low cost.
- Paper delivers a punchy attack and high dynamics, as well as precise solid highs. Expensive to produce and are subject to humidity.
- Fabric or wool is lightweight and soft, while distortion could be higher than with rigid cones.
- Metal (aluminum, titanium, etc.) is rigid but expensive and heavy.
The sound design stands for the number of features determining the way the speaker is engineered and how it works. Here are the most important elements of sound design:
- Drivers number and location. The speaker might feature a single driver to reproduce the full range of frequencies or split them between separate drivers. Besides, the drivers can be represented by separate units or make the body of one speaker (coaxial models). The number of drivers doesn’t directly influence the sound quality. Their material, smoothness of frequency response matter as well. The most frequent multiple-driver design consists of a woofer, tweeters, and super-tweeters. Still, even granted the driver’s quality is high, it should be hooked up correctly, with the right frequencies coming to it.
- Crossover. That’s an appliance regulating the frequencies distribution. It splits the outgoing sound signal into different frequency bands and sends them to the relevant drivers in a speaker. The crossover can be passive (drawing power from the source) or active (with an amp). The crossover accuracy and overall performance depend on the power output and impedance.
- Surrounding material and enclosure. The speaker’s body and surrounding material should fit tight and ensure minimal vibration to the drivers. The polymer foam, various kinds of rubber can be used as the surrounding material. The enclosure should have an optimal shape and be made of the material with good dampness (preferably wood) to submerge the vibration produced by the speaker’s work.
