Car subwoofers RENEGADE

Car subwoofers are used to produce low-frequency sound waves. They provide deep surround sound, increase the bass, and take the strain off mid-range speakers.

Car subwoofers: 7 key facts

1. These devices can be either active or passive. Active ones feature a built-in low-frequency amplifier and, quite often, an equaliser. They are supplied assembled. They help to get rid of distortion in the whole range as mid-range speakers sound clearer when the bass is removed. The design of the passive ones doesn’t include an amplifier, so you’ll have to buy it separately. There are also no controls. These devices are available at a low price. They can provide a well-balanced sound in combination with a powerful car stereo.
2. The design of a subwoofer determines how difficult it is to install as well as the quality of the sound it produces. Subwoofer components are built right into elements of the car interior trim. However, during installation, it is important to consider the specifics of sound wave propagation, resonator volume, and interior trim materials. Designers took these aspects into account when they developed enclosed models.
3. They also fall into several types. Closed box versions have a simple design and ensure high-quality low-range sound. However, they are not very efficient. Bass reflex speakers have a special port, or vent, that connects the inner chamber with the ambient environment. These subwoofers increase the pressure exerted onto the loudspeaker cone, are twice as efficient as sealed ones, and deliver a loud sound but with quite a narrow range. In bandpass boxes, the cone is placed inside the enclosure and the sound waves produced are only emitted through the ports. These appliances are the most effective ones but their design is complex and they are quite pricey.
4. When choosing a sound system, you should take into account your preferences in music. Sealed box types are suitable for pop, rock, club, classical, and instrumental music. Bass reflex enclosures are better for slow bass music, so they are an ideal option for dubstep, trip-hop, rap, R&B, etc. Bandpass boxes are widely used at car audio contests.
5. The way a subwoofer is mounted depends on the car body type. In estate cars, the loudspeaker and port should face the rear. In hatchbacks, they should be directed upwards or towards the boot. In saloons, they should face the rear seat backrests or point towards the armrests. To compensate for the loss of sound, it’s a good idea to buy equipment with extra power.
6. New speakers require special care. During the first week, it is not recommended to turn the volume up higher than 50% and then you should increase it by 10% every day.
7. You should also consider installing car interior insulation. This will help you to protect some interior elements from vibration and help block noise from the outside.
