Shallow Mount Subwoofers is not the same as full range subwoofers. The same manufacturer may make both but they are not the same product. If you are looking for something small and compact to place in your car or in your dorm room, then that is one thing. You could also look into something like an enclosure for your car to place your small speaker. On the other hand if you want to be able to listen to your music loud and clear at home or at work, then you need a full range subwoofer. Useful resource
