Shallow Mount vs Regular Subwoofers

Now we’ll discuss some key differences between shallow mount subwoofers and their regular-sized subwoofers.

Shallow mount subs come in a flat, compact, and lightweight form. This also makes them easier to install than regular subs.

Another difference can be seen in their respective enclosure boxes. While regulars subs fit inside large, bulky, and cubical-shaped boxes, shallow mount subs require smaller-sized flat boxes.

The power consumption of shallow subs is also limited. While this can be beneficial as it doesn’t put much burden on the amp, it also results in lower power output which means that sound quality will not be as high as that of a regular subwoofer.

Frequently Asked Questions
