Bass is very important for any purpose of the speaker, whether you need it for music or movies. That’s why a good bass speaker is the dream of every enthusiast. But what determines the bass of a speaker?

At A Glance: The bass is determined by the size of the driver in the speaker. The bigger the driver, the more area will be for the cone to move in. The deeper it moves in that area, the deeper will be bass, and the lower it can go in the frequencies.

Keep reading as we will be discussing a few more things and I will answer a few related queries to it. You will master the mechanism of bass and speakers after reading this article.

How is bass produced in speakers?

I don’t want to make anything complicated for you to understand. That’s why I will talk less about the technical part and come straight to the bass production process. Because our end goal is to understand that and the whole sound production process described in the above GIF.

There is a motor at the tail of the speaker driver and a coil at the head of it. The motor works on magnetic fields and electric current phenomena. The already existing magnetic field and the opposite magnetic field produced by the electric current compel the coil in the motor to move back and forth. 

This coil is attached to the cone, and the cone follows the motion with the coil. This movement pushes the air to your ear. This air moves the eardrums and hence produces the sound.

Now, this is the sound. What determines the bass? Well, when the coil can move deeper in the driver, the fuller and deeper will be the bass.

The deeper it can move, the lower end of frequencies it can hit. The lower the frequencies, the deeper the bass will be.

Keep reading as we will be discussing the perfect frequencies that will determine the perfect bass.

What Hz is best for bass?

Generally, the bass frequencies start from below 40 Hz but for deeper bass, the frequency should be lower than 30 Hz up to 20 Hz.

The bass that starts from 40 Hz is a bass that can be enjoyed and considered deep by a newbie or normal audio consumer. 

But those that have listened to bass for quite a few years they will prefer deeper bass that will be lower than 30 to 20 Hz.

But few bass freaks do prefer their subwoofer to go beyond the 2o Hz to 14 Hz or 15. 

But I don’t recommend this 15 Hz frequency for the bass. Enjoyment is fine till 24 Hz to enjoy, but beyond that, it will hurt your ears or senses. 

That’s why 25 Hz is the best frequency for the bass. You can enjoy deep bass and that too with safety.

How to get more bass out of speakers?

To fine-tune any level of the sound, you must first focus on the acoustics of the theater room. No matter how great your speakers are, how great your amplifier is. If the acoustics are not helping. Then they will all sound awful.

That’s why you must soundproof the home theater. The sound should not leak outside, or outside sound should not leak into the room. This will preserve the energy inside, and you will get filtered sound from the speakers.

Another thing to do in perfecting the acoustics is to kill the sound reverberation. To kill the reverberation you must install soft things all around the theater room and install acoustic panels on the wall, ground, and ceilings.

The soft material all around the room will absorb the sound and will not let it bounce all around the room.

I have discussed 7 more tips in this guide. How to increase home theater bass in 9 steps. Apply these steps, and you will have a blast of bass for you. I have also discussed how to keep the dB maintained for safety.

Because safety comes first.

How many watts is good for a subwoofer?

There are no exact watts for the subwoofer. Find the bass blank spots around the room. If you find it, go for the higher watts subwoofer, but if you can’t then your watts are perfect for your room.

The subwoofer should be able to fill the room with the bass. To find the blank spot in the room, you should crawl around the room to observe the areas where you feel like the bass is not hitting right. If you don’t find the blank spots, then that watts’ subwoofer is the best for you.

But if you find it, then you can go for higher watts or install another subwoofer.

Does a bigger magnet mean a better speaker?

Not only a bigger magnet but a well-built speaker is better.

Along with bigger magnets, the coil, and cone should be able to play the frequencies well. All the parts of the speaker matter, not only the bigger magnet. 

But a bigger magnet ensures a larger size of the driver where a coil can move deeper for deeper bass.

Do bigger speakers have better bass?

The bigger the driver, the larger will be the playroom for the coil to move in and the deeper and tight sound it can produce. That’s why the bigger speaker is better.

The sound of the speaker is determined by the movement of the coil in the driver’s body. A blogger speaker driver will allow the coil to play out of the box. This larger area will help it to move deeper and hence the deeper frequencies it will produce. And in a result, the sound will be fuller, deeper, and more accurate. 

That’s why a bigger driver will always have the deeper bass because its coil has a larger area to move in it.
