Frequently Asked Questions

1.Does the type of enclosure make a difference?

Yes, the type of enclosure does make a lot of difference when it comes to sound quality. Suppose if you have a high-end speaker along with a badly engineered enclosure, then it will produce worse sound.

Also, the size of the enclosure depends upon the size of your subwoofer. So, you need to choose your enclosure wisely.

2. Does a subwoofer need an amp?

The passive subwoofers require an amp to work. These subwoofers cannot function on their own without being supplied by an amp. These subwoofers are specifically manufactured to deliver low frequencies.

Therefore, these need a particular amount of power to produce the perfect bass effect. And to achieve an adequate amount of power, the right type of amplifier is needed.

3. Can I get away with using a cheap amplifier with the subwoofer?

It depends upon the sound quality you want and the size of the subwoofer you are using. As the size of the speaker gets larger, the need for amplifier increases because the speaker needs the power to get moving. If you want seamless results, then you need to add amplification.

You can also check out some other options available in the market, like, active subwoofers. These subwoofers already come with an amplifier. You can select one of the best 8 subwoofers according to your requirements.

4. Does the material of the subwoofer cone make a difference?

The heavier the material of the cone, the more energy it stores. It results in more distortion and other issues. More rigid material results in a better and flattering response and produces very negligible distortion in the frequencies, which are above human audibility.

The subwoofer cone should be made of a material that has a balance between weight and rigidity. Therefore, the apt material for any cone depends upon the other mechanical and electrical properties of the driver as well. Generally, paper, Polypropylene, aluminum, etc. are used to make subwoofer cones.

5. What is the best shallow-mount subwoofer?

The shallow mount subwoofers are compact. For instance, PWE-S8 by Alpine electronics gives outstanding bass output within a compact space. Such a subwoofer is perfect for vehicles as it takes very little space ad comes with Durable built quality and a Flexible sound setup.

6. Which are better – 2-ohm or 4-ohm subs?

When we compare 2 ohm and 4-ohm subwoofers, the biggest difference is the price range. The 4-ohm subwoofer would be cheaper than the 2 ohms.

When it comes to quality, there is a slight difference of 2.5 dB, which a layman would not be able to notice. If we run both the subwoofers on the same power, then the sound quality will be somewhat similar.

7. What’s the difference between subwoofers and speakers?

The most basic difference between a subwoofer and a speaker is the frequency range. The subwoofers or woofers find use in covering the low-frequency spectrum of the sound and deliver the bass effect.

However, on the other hand, speakers focus on the electro-acoustic transducer. Speakers deliver output in every frequency range, but woofers have specifications for the lows only.

8. Is the subwoofer powered, or will it need an amp?

If your subwoofer is already powered, then you won’t need an additional amplifier because the amplifier is in-built in powered subwoofers.

However, if you are using passive speakers, then you would need an amp. Moreover, you can add an amp if you want to your powered best 8in subwoofer as well.

9. Does the sub have single or dual voice coils?

Both single and dual voice coils subwoofers are available in the market. The single voice coil subs are cheaper than the dual voice coil subs. The SVC has a single winding, and the DVC has two separate windings.

The Dual voice coil subs offer better wiring options to adjust the amplifier according to your liking. The DVC is a better and popular choice for the best 8-inch subwoofer car audio for more flexibility in setting up the wiring.

10. Is the sub’s frequency range wide enough to allow the sub to produce deep low frequencies?

The subwoofers are specifically engineered to produce deep, low-frequency sounds. The better your subwoofer is, the better, crisp, and clear bass effect it will produce. The general frequency range of a subwoofer fluctuates between 20–200 Hz.

11. Is the new 8-inch speaker compatible with my audio system?

If you already own an audio system, then it is important to cross-check whether the subwoofer you are planning to buy has compatibility with the existing system. You also need to check the impedance value of the subwoofer.

For example, if your audio system is working on 4-ohm impedance, then the subwoofer should also be of 4-ohm impedance.

12. Should I go for a single voice coil or a dual voice coil 8-inch sub?

If you want a budget-friendly upgrade for your music system, then you can go for the single voice coil 8-inch sub. The bass results in an SVC are satisfactory. The bass effect in a DVC is way better than the SVC, so it would be the best 8-inch woofer. Therefore, it entirely depends upon the personal choice of the user.
