The subwoofer craze will never fade and it just keeps getting better day by day. 

SPL Subwoofers have been designed to do one thing and one thing only, rattle your bones. These woofers can literally blow you away and they promise powerful performance with bass that you can never get on a SQ Subwoofer. 

To understand what you’re getting into, you need to know what’s the primary difference between SQ Subwoofers and SPL Subwoofers.

What Are SQ Subwoofers?

SQ Subwoofers are woofers designed to be clear and offer Hi-Fi sound by allowing you to experience every single frequency of the song that’s playing. You may not get the bass you’re looking for with SQ Sub, but you will definitely have a balanced car audio system.

What Are SPL Subwoofers?

SPL Subwoofers are those woofers that are not made to target clarity or fidelity, but are built to be extremely loud. SPL Stands for Sound Pressure levels, so basically SPL Subwoofers are those that come with a higher decibel rating and can end up being extremely loud.

Here are the top 6 best SPL Subwoofer brands:
