Main Features Explained


Before making the purchase of the best car speakers, it is necessary to take into account structural things, such as the size of each piece, since this influences their organization and the choice of the place where they will be placed. There are certain cars in which the installation is on the sides, while most focus on the rear. 

In this case, this purchase comes with two pieces: a woofer and a tweeter. The woofer cone, in charge of the bass, has been made of mica, a resistant material suitable for this type of item and, furthermore, it has a diameter of 16 centimeters. On the other hand, the tweeter is made of polyetherimide and comes with dimensions of 2.5 centimeters; this piece is responsible for the production of high-pitched sounds. Both components require a depth of 4.3 centimeters to be able to make the correct assembly. 

To add extra durability and strength, manufacturers have used Hybrid Surround technology, which uses two materials to create a hybrid edge that also contributes to the final sound quality. In this case, the elements used are rubber and fabric. Installation requires little time, if you know about this type of product, so in minutes you can enjoy the music you want to listen to on every walk you take. 

Technical specifications

The structural part of the speaker set pieces and their design are important aspects, however, the first thing to consider when making a comparison of car speakers is each of the technical specifications given by the manufacturer. 

Speaking of power, this device accepts an electrical power input of up to 300 watts without problems. In addition, it has an impedance of 4 Ohms to resist electrical current without affecting the sound produced by the speakers. This data is based only on the ability of the speakers to withstand the passage of energy through them, however, when talking about sound quality, this pair of speakers has a nominal power or RMS of 30 W, which indicates that this is the maximum power of the product with completely safe operation, without distorting the sound. 

The sensitivity level of both the woofer and tweeter is 92dB, a number that’s right in the middle of normal car speaker parameters. The frequency response range is wide and, despite being a two-way device, it manages to produce a wide range of sounds. Manufacturers do not specify their peak power, so it is recommended not to exceed the volume. 

coaxial system 

When among the opinions you are looking for, the relationship between quality and price is given greater value, and if you are considering acquiring one of the cheapest models, those with coaxial systems will surely be the first to attract your attention. 

This is because its structure is one of the most practical and versatile on the market, since, despite being a system made up of different parts, they are integrated and work to handle all possible frequencies together, offering a wide range wide sound without the need for additional elements. In a two-way coaxial system, the woofer is the device in charge of reproducing all the low and medium sounds, while the tweeter type speaker focuses on the reproduction of high and medium-high frequencies. This is the exact case of the model offered by JVC.

As it is not a separate track artifact, the sound quality of the set is not professional, because as each piece is responsible for reproducing several frequencies, the noise can weaken and sound less intense than desired, especially the bass. This does not mean that it is a poor quality product at all, but that it is made for everyday use and should be used under this criteria, without expecting a 100% faithful and professional sound.
