Most people love loud music, especially when the bass is powerful. However, choosing the right subwoofer can be tasking. Mostly, people choose to buy a high-quality amplifier which is expensive. In this article, How to make subwoofer louder, I will guide you on simple adjustments to your subwoofer and help you regain or attain louder sound without spending more cash.
First, you need to get familiar with different types of subwoofer enclosures. Enclosures help the subwoofer to maximize its potential and its role play in the sound system. They protect the unit and boost the sound of the bass if you match the right subwoofer to the suitable enclosure.
Enclosures depend on the type of bass you want, like a boom or tight.
Types of enclosures
The sealed enclosure has no air out of the box, making it necessary to have a higher watt amplifier to drive the subs.
The importance of the sealed enclosure is it produces excellent low-frequency bass. It is the best when playing hip hop as it produces deep, precise bass. However, it’s not the most recommended when playing jazz or rock because it is less boomy, and music may not sound so good.
They have one or two vents placed at the front or the back of the box. The vents allow powerful bass to be generated without the need of a powerful amplifier. To work, the measurements should be accurate to the dimensions of the box. Do not eyeball the size of the box. Because of these perfect dimensions, the ported enclosure is loud and has more bass, best for hard rock or metal music.
This is a mix of sealed and ported enclosures. It has two chambers, one sealed and the other ported with sound waves coming out of it.
It’s possible to produce low-frequency delivery performance excellently while limiting resonance. You get to play all genres of music with the best bass. The bandpass should not be tuned to the frequency of the port, and it’s something to watch out for.
How to improve the sound of a subwoofer
1.Tune the subwoofer properly
Tune in the unit controls correctly and listen to the output to confirm if you are getting louder and precise sounds. If you don’t adjust them properly, the main speakers and the subwoofer competes in the bass frequencies and cancel each other out.
Cabinets are covered from inside using sealants as a way of improving bass. Also, using a soft material like fleece or felt, glue it to the walls. This deepens the bass.
3. Adjust an amplifier
Purchasing of a good amplifier like BOSS Audio Systems R1100M Monoblock Car Amplifier doesn’t just increase the volume of your audio; it adds clarity in a new dimension to the sound by sending precise signals to the speakers. It improves the audio quality, and you can hear instruments and sounds you have never heard in your favorite song.
Test it by playing a middle bass song, increase the volume to 80%, and if you don’t hear distortion, advance slowly.
4. Select the right size of box for a ported enclosure
When it comes to subwoofers, big boxes don’t guarantee louder sound, just lower bass responses. If your box is large than the ideal subwoofer, it won’t sound good. The over-excursion of the free air damages will likely damage the subwoofer.
On the other hand, a smaller box will produce more power to perform the same.
Therefore when selecting the right box to your speakers make sure you select the right one to fit your speaker. Below are few sizes of subwoofer sizes that are available on Amazon
- Atrend BBox E12D Dual 12″ Sealed Carpeted Subwoofer Enclosure
- SCOSCHE SE10KT 10-inch Single Car Speaker Enclosure
- Atrend Bbox SC6.5PRC 6.5” Pro Audio Tuned Speaker Enclosures
5. Properly position the subwoofers
The position of a subwoofer will surprisingly make a difference, as it influences how the volume of the bass will flow in your car.
By setting it at the corner, the bass gets boosted up to six decibels without an amplifier. If the port is located at the back, leave at least 3 inches of distance from the walls. Placing them in an asymmetrical position relative to the car wall boosts the bass.
6. Use high-quality audio files
Many players are currently trying to compress their music files. This makes the audio lose the lower and high-frequency information and other details, making music exciting and loud. When you play the compressed audio file using earbuds or headphones, it’s unnoticeable.
When you are choosing music files, go for the one which has a high bit rate. Some formats have the best audio quality. They are FLAC and AIFF. If you streaming music, chooses apps that have high resolution and ensure the settings guarantee high sound quality.
When the music file is of high quality, it directly impacts the quality of sound your subwoofer will produce.
7. Reduce electrical impedance
For a subwoofer to work efficiently, it needs to convert the electric charge into sound without any limitation. Electrical impedance is used to measure the degree of resistance that a subwoofer faces to perform this function. If your subwoofer have got a high impedance, its ability to convert the electric charge into audio is less.
To minimize the electric impedance, ensure that coils and magnets are fully operational. The circuitry that controls your subwoofer should be in perfect shape to discover that.
You should consult a technician if any components should be replaced
8.Replace the cable
If cables are old in your stereo system, they will affect the electrical signaling, which leads to poor sound quality. The cables should be replaced from time to time and they should be of quality and adequately sized. To avoid the struggles of replacing cables every time you should purchase the best quality like Mediabridge ULTRA Series Subwoofer Cable (15 Feet)which enables the current to flow freely, and feeds enough electric power to the speakers to operate adequately.
9. Add an improved heatsink
Heat damages many electronics. A subwoofer circuitry generates heat which can affect a subwoofer. Most subwoofers have built-in amplifiers, and they produce a lot of heat.
To disperse this heat fast, a heatsink is added. You can replace your heatsink with a larger one. Heatsink are usually located at the back of your subwoofer or on the subwoofer circuit board.
A thin layer of heatsink compound should be applied on the contact surface and glue down the heatsink sides since you can’t drill down like the original one.
Amplifiers can be a big help when trying to boost sound quality. Nevertheless, with the above tips, it’s easy to achieve the desired volume.
Moreover, if you must get an amplifier, you have to think about the type of amplifier best fit for your subwoofer.
