Price Range
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
Number of Subwoofers
This value represents the number of subwoofers that the enclosure accommodates or that are included in the package or bundled kit.
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Total Peak Power Handling
This is the Total Peak Power handling of all the subwoofers included in the package or enclosure.

If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total peak power handling for all of the subs combined.

Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements.
