Key Features To Consider When Choosing The Best 15 Inch Subwoofer:

Choosing a subwoofer is not only about visiting your local sound store and choosing the first one you see. There are a couple of intricate features you will need to understand and we have done some of the legwork and talked to a couple of experts to help us find these subs.

Here are a couple of the key features you will need to keep in mind:

  • Power

    With more power, you will have more sound thus more fun. Nothing can be more frustrating than having a subwoofer without the right amount of power. The power is generally split into either RMS power or Max power. It is worth noting the RMS power is always better the max power and having an RMS power output of around 750W, will surely keep the party booming.

  • Voice Coil

    The voice coil is another important aspect of the subwoofer and you will need to keep this in mind as well. The more voice coils you have, the better the sound will be, but the different designs should also be taken into account. You will also notice that various different metals can be used to keep the voice coils protected.

  • Impedance

    When it comes to impedance, less is always better and with less impedance, you will have clear and crisp sound. The impedance is generally indicated on the sub as well.

  • Frequency

    The frequency will capture the highest and the lowest of sounds. This means that a wider range of frequency will capture the best of both sounds. If you like high pitched sounds, you will look for a higher frequency, whereas lower bass sound will need a much lower frequency if you are to catch them correctly and have the best sound.

  • Driver Size

    When it comes to low bass music, the driver size is fundamentally important and it is generally in proportion to the bass. 15-inch subwoofers will have a much larger driver and this means that they have better bass, whereas smaller subwoofer might not give you such great sound on those lower notes.

  • Build Quality

    If you are new to the world of speakers, you might not know how important the build quality is. However, it is worth noting that everything on and surrounding the speaker will affect the quality of the sound. Speakers are mostly packed and enclosed in boxes, but the materials are fundamentally important and if you pack an expensive speaker around cheaper metals, you might not get the same quality sound.

  • Adjustability

    This might be another area of concern for beginners and it is fundamentally important to understand the adjustability of the subwoofer. While it can take some time to get used to this new piece of technology, once you have it done, you can be ready to enjoy great sound without any hassles and customize it to your needs.

  • Integration

    This will need to be kept in mind if you are using the subwoofer with different parts and different brands. As a rule of thumb, it is much better to keep to the same brand when you are building up a sound system. If this is not possible, you will need to ensure that your new sound system can be integrated with the other parts.

  • Crossover

    The crossover is the final part of the puzzle you will need to keep in mind and it is the circuit that prevents the subwoofer from picking up the wrong frequency. It also ensures that sound is never distorted in any way and the right notes are picked up. A crossover of 100Hz is generally recommended as the best option.

    Ok every time I read a review its these brands. What about sundowns a-x series, dc audio, DB, psi , and DD. I e heard a lot of subs and I’ll take an a series or dc level two or psi level one over any of these Junkers. Hifonics has lost it quality it had in the 90’s and the kicker is corporate junk since the list the glory of the Stillwater C-series, Rockford is solid but this is far from there best sub. JL led the way with modern designs in the W7 but has since become the over priced black sheep of the car audio world putting its ego engineering twords home audio subs. This is a bought and paid for review. Power accoustic really they had to throw their best to compete with budget 15″ subs.
