Should you choose 15 inch subwoofers or 12 inch subwoofers for your car? That is good question, and really only you can answer it. When you’re attempting to choose the right after market sound system for a car, the choice of subwoofer size can seem daunting. The size of the vehicle, the type of music you listen to and even how much power you have available should all be taken into consideration.
The answer to the question of whether 15 inch subwoofers have better base than 12 inch subs is not an easy one to answer. The fact is, “better” is a personal opinion. 15 inch subwoofers are larger and displace more air than 12 inch subwoofers do, so the 12 in will have a crisper, sharper sound than the larger ones.
The choice of subwoofer is really based on the music you listen to and the frequencies inherent to the music. The basic rule is, the larger the speaker, the lower the sound that comes out of it. A subwoofer that’s too large can cause distortion of the music.
For most 12 inch subwoofers the frequency range is 45 hz on the lower side and around 500hz on the upper. The human ear can hear frequencies between 20 hz and 20,000 hz.
Rap and hip hop music often hit frequencies of around 40hz, so if you want a lot of boom, a 15 inch subwoofer may be a better choice for that type of music then a 12 inch subwoofer. If you’re looking for bass that has a rich, tight sound, a 12 inch subwoofer between 80hz and 150 hz is the better choice.
