What are Bass Blockers, and how do they work?

If you do not know what Bass Blockers are and how they work, you aren’t getting the most out of your speakers. So many people who use speakers but don’t know about bass blockers. In this article, you’ll get to know everything about bass blockers and how can you use them in your speakers.

In short, the bass blockers are a kind of filters that filter out the lower audio frequencies from the speakers letting the sub-woofer elements produce the bass sound. They also improve the quality of the bass sound.

Now, let’s know everything in detail about bass blockers-

What Are Bass Blockers?

Bass Blockers are the filters that impede low frequencies from damaging your speakers and increase their life span. They also work as an external equalization device by cutting out the low bass frequencies from the signal that goes through the bass blockers. Low frequencies are sometimes responsible for rattling noises.    

The bass blockers can be used in all kind of speakers that don’t reproduce the bass sound, and they are probably the cheapest alternative to external equalization devices. You can boost the performance and power of the midrange speaker by installing the bass blocker.

So this was about bass blockers and how they work to get you the most out of your speakers.

What Are The Benefits of Using Bass Blockers In Your Speakers

  • They protect your speakers from audio distortion.
  • They prevent the rattling noise from coming from the speakers.
  • They keep your speakers from blowing that usually happens due to low-frequency sound.
  • They enhance the performance as well as the life span of your speakers (especially midrange speakers).

So these are the benefits of using bass blockers in your speakers, and you must’ve found them impressive. Now, let’s know if they are worth it or not.

Are Bass Blockers Worth It?

The average cost of a pair of good quality car speakers is 80 USD, and the average price of a bass blocker is 10 USD. Now, as you know that the low-frequency sound sometimes blows your speakers, you also read above in this article that using bass blockers can prevent your speakers from blowing.

If you compare the price of the speakers to bass blockers, you will see that there’s a huge difference, and if you use a 10 dollars bass blocker, you would not have to worry anymore about your speakers. Apart from that, they will also enhance the performance of your speakers, which will ultimately improve your experience.

This clearly shows that the bass blockers are worth it. What brand of car speakers are you using, and how much do you rate them out of 10? Please let me know in the comment section.

What Kind of Bass Blockers Do I Need?

First of all, find out what’s the size of your car speakers. You can refer to your vehicle’s manual to know about it. Now, visit the nearby store and buy your speakers’ size bass blockers. You can easily find the bass blockers in the store as most of the stores have started keeping them.

You can also order them on Amazon if you don’t want to go outside to buy them.

How to Install Bass Blockers?

You’ve known probably everything about bass blockers, and now it’s time to understand how can you install them in your speaker. You’ll need to have some components to execute the process, and here are they-

  • Bass Blockers
  • Electrical tape
  • Male and female spade connectors
  • Your vehicle’s repair manual
  • A ratchet set
  • Wire cutters

Here is the step by step process-

Step 1: Pop the hood of your car and disconnect the negative cable of the battery.

Step 2: Remove the interior components using the Ratchet set to get access to the back of your speakers. (If you don’t know how to remove the interior components, consult your car’s repair manual).

Step 3: Find the positive speaker wire connector and cut it using a wire cutter. I recommend using BOOSDEN wire flush cutter, which is best for precision cutting.

Step 4: Now, strip 10 mm of insulation from both ends of the positive speaker wire.

Step 5: Now crimp the male spade connector to the positive wire of the speaker and the female spade connector to the stereo head.

Step 6: Take the bass blocker and connect it with the female spade connector and positive speaker wire.

Step 7: Connect the male spade connector to the positive stereo side.

Step 8: Wrap the electrical tape around the terminal connection of the bass blocker.

Step 9: Now, reconnect the negative battery cable and close the hood.

Step 10: Finally, get in the car and turn on the sound system. If the speakers are working correctly, pat your back, you did a great job.

So this is how to install the Bass Blocker in your car.

Important note: If you haven’t installed the bass blockers correctly, you might hear some unnecessary noise coming from your speakers, and in the worst-case scenario, your speakers would blow. So make sure you go with the step-by-step process so that you can install it the way it is supposed to be.

If you don’t want to spend money on buying Bass Blockers, you can make them yourself. Let’s know-how can you do it-

How to Make Bass Blockers?

To make your bass blockers, you’ll need to have Capacitors that you can buy from an electronic store.

Now, here are the steps that you have to follow-

1. Find the speaker’s impedance for which you want to make the bass blocker and that you can find on the sticker affixed to the back of the speaker.

2. Now, decide which frequencies you want to block. Most bass sounds are below 150 Hz, so that’s a very common value to use.

3. Calculate the value of the capacitor in Farads using this formula- C=1/2 (2*pi*R*FC), where C is the capacitance in farads, pi is 3.14, R is Impedance in ohms (Ω), and FC is the frequency.

4. Now, use the calculated (capacitance) value to source the correct impedance capacitors. If you can’t find the exact value, join the capacitors in parallel to add in capacitance. For example- connect a 350uF capacitor and a 400uF capacitor to make 750uF.

5. Splice the capacitors and then connect them to your speakers and ensure to do it before the signal reaches the speaker.

6. Finally, connect the splices using a soldering iron and then wrap the electrical tape around them. If you connect more than one capacitor, keep them in parallel and remember to join positive terminal to positive terminal and negative terminal to negative terminal.

This is how you make bass blockers using capacitors. This process is a little bit challenging, and most people mess with it. You’re advised to buy the Bass Blockers if you’re unsure that you can make them yourself.

Conclusion

So here you got to know everything related to speaker Bass Blockers. You’re advised to use them to increase the performance and life span of your speakers. The bass blocker installation process is also easy, and you can get it done in minutes.                                                                                                                                                    

Frequently Asked Questions (FAQs)

Here are some frequently asked questions related to bass blockers-

Does lower Hz mean more Bass?

Hz (Hertz) is defined as the unit of frequency, and lower Hz indeed means more base. When you lower the frequency scale, the Bass becomes deeper, and as you keep lowering it, then at a point, you only feel the bass sound.

You can feel the Bass at 60-250 Hz. At 250 Hz, you feel the Bass without the loss of definition of the music, and that’s probably the best frequency for Bass, and at 40-60 Hz, you feel the deep bass sound.

Yes. They both are the same.

If you are using smaller-sized speakers, the 600 Hz Bass Blockers will be best for that low-powered system and 800 Hz Bass Blockers will be best for the high-powered system. Most cars have smaller size speakers. Here’s the size of a smaller speaker – 3-1/2″,4″,4″×6″.
