Selecting a subwoofer is quite easy when you need to check the common features and specifications. But, when it comes to understanding SPL and SQ of a sub, many of us confuse both terms’ differences and meaning.

SPL means sound pressure level, which measures the volume of sound that how loud it could be played without any distortion. The unit in which SPL could be measured in dB.
SQ means sound quality, and SQ subwoofers are specially designed to check the spectral balance and tonal quality of sound. It has less relation to the volume of sound.
