By reducing the low frequencies, they aim to make the mid and high frequencies seem better, claiming it's for low distortion. In reality, this is all deception, as they can't technically enhance only the 100Hz frequency range without affecting other ranges.)

The primary limitation here is that it's nearly impossible to boost only the 20-200Hz range without affecting the 300Hz range; excessive boosting in the 300Hz range leads to muddiness in the sound. However, with our Castor's dual-driver design, one driver is dedicated to independently handling the 20-200Hz frequency range and fully amplifying the output within this range.
