Best 12 Inch Subwoofer Review & Buying Guide 2021

What is a subwoofer?

A subwoofer is a speaker that is loud which is designed to produce low-pitched audio frequencies. These low-pitched audio frequencies are known as bass and sub-bass. These are generally lower in frequencies than those generated by a woofer. The first subwoofers were developed in 1960 to add more bass to the home stereo systems, you can use both center panel speaker & 12 inch Subwoofer, just pairing them. In this article, we will share you list of best 12 inch subwoofer (list of best 10 inch subwoofer here), check below

What Is the Distinction Between a Passive and Powered Subwoofer?

Subwoofers are driven or inactive.

To begin, let us discuss passive subwoofers. Passive subwoofers have encased woofers that must be driven externally. Passive subwoofers typically provide a smoother sound and provide more flexibility in terms of total wiring configurations.

Powered subwoofers incorporate sealed woofers to provide control to the subwoofer. Although these subwoofers are simpler to understand and control than passive subwoofers, they normally do not provide the same amount of sound quality as passive subwoofers.

How to build a 12-inch Bass Subwoofer Audio box?

Building your subwoofer box is an excellent thing because it will give you the great look and design you want. Before building a subwoofer box, you need some tools, materials and hardware.

Materials needed

  • Jigsaw
  • Table saw or circular saw
  • Electric drill with bits
  • 3/4″ MDF (medium-density fiberboard)
  • 2-inch drywall screws
  • Panhead sheet metal screws (1/2″ and 3/4″)
  • Carpenter’s glue
  • Silicone caulk
  • Non-hardening rope caulk
  • Speaker terminal cup

Time needed

Building your subwoofer box takes about an hour and a half. It also differs from one person to another because of its box design and complexity.


  • Determining the minimum height of the box
  • Determine the minimum width and depth of the box
  • Determine the available space in your box
  • Sketch the design of your box

Rectangular box                             Wedge box


Height: 13″                                        Height: 14″


Width: 14″                                          Width: 18″


Depth: 12″.                                        Depth 1: 5″


Depth 2: 8.”

  • Determine the internal dimensions of the box


Rectangular box                             Wedge box


Height: 11.5″                                     Height: 12.5″


Width: 12.5″                                      Width: 16.5″


Depth: 10.5″                                      Depth 1: 3.5″


Depth 2: 6.5″.


  • Calculate the internal box dimensions in cubic inches

For example: 11.5 x 12.5 x 10.5 = 1509.375 cubic inches

  • Convert cubic inches to cubic feet

For example: 1509.375/1728 = 0.873 cubic feet

  • Adjust your box’s volume to match the subwoofer specifications
  • Determine the final exterior of the box

Handling of Power

There are two levels of control to remember when it comes to subwoofer power handling: RMS (root mean square) and Peak. RMS capacity relates to the amount of power that a subwoofer will reliably manage over time. This is the most critical factor to remember while purchasing a subwoofer. The higher the RMS of a subwoofer, the clearer and more efficient it should be reliably.

Peak output is the highest level of power that a subwoofer can handle in brief bursts. This would be greater than the RMS, but is not as important to remember. Finding a subwoofer capable of handling the amp’s capacity is important.


Subwoofer sensitivity relates to the amount of power used to generate sound from a subwoofer. The greater the sensitivity of a subwoofer, the more sound may be squeezed from less fuel. Sensitivity levels for subwoofers should be between 80 and 99 dB.

You’d find the more responsive the subwoofer, the better. This is not necessarily the case, though. Certain subwoofers are very sensitive and readily muffled and blurred. In general, you’ll want a subwoofer with a sensitivity of about 90 dB. This is the optimal level of sensitivity.

Matching the Impedance of the Subwoofer to the Impedance of the Amplifier
The most difficult aspect of purchasing a subwoofer is matching it to the appropriate amplifier. To do so, you would take the impedance of both devices into consideration. To begin, you must determine the RMS wattage of your subwoofer. After determining this, you must locate an amp capable of supplying between 125 and 200 percent of the subwoofer’s total RMS wattage.

The second parameter to check is ohms. The majority of mono amps are capable of driving two-ohm loads. Since the majority of two or four channel amplifiers are not capable of delivering 2 ohms when bridged. You cannot attach a device with a low impedance to an amplifier.

Single voice coil subwoofers can only be matched with amplifiers that have the same ohm rating.

For example, a single voice coil subwoofer with a resistance of 2 ohms can only be matched with a resistance of 2 ohms.

You may attach the dual voice coil subwoofer in series or parallel.

As an example, consider a dual voice coil subwoofer wired in series at 4 ohms: 4+4 = 8 ohms; (4*4)/(4+4) = 2 ohms in parallel wiring. It should be remembered, though, that it works better when paired with a low-ohm amplifier. The lower the ohm value, the greater the total power.


If you want a tall, rounded, complete volume, a subwoofer is a must-have. The 12-inch subwoofer is the most common size available. If you may go larger or smaller, you can give up either control or capital in the process. When it comes to selecting the best 12-inch subwoofer, there are a few factors to remember. However, once you weigh any of these factors, you should be able to locate a subwoofer that is a better match for your sound setup.
