The 2 Ohm voice coil may be wired for 1 or 4 Ohm settings, giving you the flexibility to match your amp. It has a wide frequency response range of 20 to 200 Hz, which is more than enough to pick up on the low frequencies that cause your automobile to shake.

It’s also a long-lasting free-air subwoofer with a Mica-injected resin cone that’s both hard and light, allowing it to fire at high pressures without distorting the sound. This design is able to move more air than previous versions, resulting in a bass response that is both powerful and accurate.

Frequently Asked Questions

What Is a Free Air Subwoofer?

Although a free-air subwoofer is the most basic subwoofer installation option, it does necessitate specially built subwoofers. Free air subwoofers don’t need a mounting box to function properly. Subwoofers are commonly mounted in the rear deck or affixed to a board put between the backseats of a car and the trunk in a free-air system.

This board creates an airtight seal, effectively enclosing the entire trunk – this is known as infinite baffle (IB) design (more on that later). However, it should be remembered that employing a free-air subwoofer may degrade sound quality to some extent.

A subwoofer put in a well-designed enclosure will sound far better than one mounted in the open air. Furthermore, whatever you put in the trunk may hinder the sub(s) from sounding as well as they could, which can be inconvenient for normal car use.

When you’re mounting a sub or a couple of subs on your rear deck or behind the backseats, keep this in mind. It’s highly advised that you apply a sound deadening substance like Dynamat or Hushmat in the trunk to improve sound quality.
