Best Shallow Mount Subwoofer

Getting an excellent bass is not hard when the car has a lot of space and you’re using the large subwoofers. But when a space for installation is limited, for example, when you want to install a subwoofer in an invisible place or install it in a sports car, it becomes more difficult to obtain low-frequency waves of high quality. The only option to achieve the goal is to use small subwoofers of 6.5 or 8 inches. But if your goal is to get superior sound, then you need to look for a smarter solution and that’s the shallow mount subwoofer offering high performance and small size for installation in very narrow places. Further, we will tell you in details about the distinctive features of this device and reveal the best shallow mount subwoofer on the market in 2017.

Shallow mount subwoofers are designed specifically to be installed in places where it is difficult to locate a conventional sub. Thus, the main difference is the installation depth. Moreover, you won’t find large speakers in terms of diameter. The usual size of shallow mount subs is 8, 10, or 12 inches.

The main advantage of this type of subwoofers is its compact size and portability. You can add to this an ease of installation, which is due to a thoughtful design. By installing a shallow mount sub you won’t weight down the vehicle and you still have plenty of space in the trunk. If necessary, you can also easily take a sub out and transfer it to another car.

As for the drawbacks, they also exist. In order to make such woofer produce a powerful and high-quality bass, the design should be well thought out, but manufacturers often do not care about it. As a result, the user receives a sound of a doubtful quality, but only in a compact size. In contrast to easy installation, there is such a disadvantage as the fragility of mounts. From vibrations, during the car movement, such sub may simply fall out or suffer from other damages.
