Good brands generally have a better bass but they also come with a slightly bigger price tag. When placed in strategic positions, they have the capacity to realistically recreate all the frequencies in the audio spectrum. Hence, if you are an audiophile, it is highly recommended that you check these out before settling down for a particular option.

Components of a subwoofer and their role in the overall performance

It is always the components that decide the performance of the subwoofers. Having a good knowledge about them would, therefore, give you a better idea about the working as well. The integral components of a subwoofer are dust cap, diaphragm, voice coils, spider, basket, magnet and suspension and each of these are important to the subwoofer.

The voice coils determine the vibrations during sound production while the spider, which is connected to the basket, adds stability to the subwoofers and protects them against damage especially due to strong vibrations. The diaphragm also has a central role in audio reproduction as they solely determine the conversion of vibration into audible sound waves. For the loudest tones, the diaphragm relies on the amplification. The subwoofers are, therefore, a very compact and complex structure and any minor difference in the components can have a marked difference in the output.

What is the benefit of having an 8 inch subwoofer installed into your car?

First of all, it is a point to note that there are not many options when it comes to car subwoofers. Installing a large-sized subwoofer is out of the question. Hence, you will have to settle for something that is smaller but also very efficient.

Things to consider while buying the best 8 inch subwoofer

1. Power handling

When you are checking for the power handling, you should always consider the RMS (root mean square) and peak power. Peak wattage is the maximum power that the subwoofer can handle for short periods of time without getting damaged. RMS wattage, on the other hand, is the measurement of power consumption in a continuous stream and it will give you a better idea about the average power consumption of the subwoofer.

2. Sensitivity

The sensitivity of a subwoofer is measured in decibels and it is the efficiency of a subwoofer in converting the power into sound. The more sensitive a subwoofer, the higher amount of sound it will be able to produce.

3. Impedance

Impedance is nothing but the amount of resistance present in the electrical circuits of the subwoofer. Better impedance would mean a better balance between the input and output of the subwoofer. The best 8 inch subwoofer would generally have an impedance of about 4 ohms.

4. Frequency response

Frequency is the measurement of the range of audio wave frequency that a subwoofer can sense and reproduce. It is measured in terms of hertz. A wider frequency range would mean that the subwoofer will be capable of reproducing every sound with high clarity. Subwoofers with lower base numbers are more efficient at reproducing deeper tones and low range bass.
